Title: Improvements in or relating to an actuating device for alternately opening and closing electric switch controls
IPC: H01H13/56
Filed: 1955-07-28
Abstract: 788,371. Electromagnetic relays; switches held set and freed mechanically. SIEMENS & HALSKE AKT.-GES. July 28, 1955 [July 28, 1954], No. 21878/55. Class 38 (5). A mechanism for operating switch contacts " on " and " off " by successive depressions of a push-member may be applied to a relay or to a hand-operated push-button switch. A relay (Figs. 1, 1a, 1a<SP>1</SP>, 1c, 1c<SP>1</SP>) comprises an armature A attracted to a core K to lift a plate-like slider 2 guided for vertical movement in a channelsection base-plate 1. A lug 2a on the slider co-operates with the tongue 3a of a U-shaped rocker member 3 so that that end of the member 3 is also lifted to engage a post P and close a pair of blade contacts F. The other end of the member 3 is apertured at 3c whereby it is supported on an extension 1b of the base 1. A spring 4 connected between a depending arm of the base 1 and the member 3 holds a depending arm of the member 3 against a tongue 1c extending into an opening formed in the horizontal top part of the base-plate 1, Figs. 1, 1a, 1a<SP>1</SP>. The said depending arm of the member 3 has a window 3d and when the member 3 has been lifted the window receives the tongue 1c, the member 3 moving bodily to the left as viewed in Fig. 1a<SP>1</SP> by the action of the spring 4. Thus when the armature is released the member 3 is held latched but it tilts, however, so that the inclined upper side of the aperture 3d rests on the tongue 1c, Figs. 1c, 1c<SP>1</SP>. On the next momentary energization of the relay the lug 2a engages the back of a further tongue 3b of the member 3 so that the member slides bodily along the base 1 towards the right to release the aperture 3d from the tongue 1c and the spring 4 pulls the member down, permitting the contacts F to open. On subsequent release of the armature the parts assume their initial positions. A modified " on "-" off " mechanism is shown incorporated in a manual push-button switch (Figs. 2a, 2a<SP>1</SP>) and in a relay (Figs. 2c, 2c<SP>1</SP>). The push-button switch comprises a push-button 6 carrying an insulating slidable bush P operating contact sets f1, f2, the bush being lifted by the rocker 3 when the latter is raised by a projection 6a on the button. The rocker 3 is latched as previously described by a tongue 1c received in a rectangular-shaped window 3d by the action of the spring 4 but the rocker does not tilt as in the first embodiment. Upon release of the button the projection 6a disengages the rocker and permits the latter to rotate counter-clockwise, Fig. 2a<SP>1</SP>, so that on the next depression of the button the projection moves behind the member 3 and releases the aperture 3d from the tongue 1c, thereby permitting restoration of the parts to their original positions under the action of springs 4, 6b, 6c. The relay, Figs. 2c, 2c<SP>1</SP>, operates similarly, the armature A lifting a slider 2 having a tongue 2a co-operating with the member 3.

Abstract: 1,043,421. Bridges; expansion joints. E. LUBBERT, U. FINSTERWALDER, R. JECHT, E. RUF, E. LUBBERT, E. LOFFLER, G. LUCKING. May 31, 1963 [June 1, 1962; March 28, 1963], No. 22005/63. Heading E1G. A prestressed concrete elevated roadway comprising rectangular slab sections 2 cantilevered from central columns 1 and joined lengthwise of the carriageway by freely suspended slabs 3 has resilient tension members 7 rigidly anchored in contiguous sections 2, 3 and bridging the expansion joint 6 and means for distributing the temperature expansion over an appropriately long length of the surface covering 15. The tension members 7 are anchored at each end by rods 13 cast in concrete 12 embedded in the sections 2 and 3, and pass through holes 17 in transverse concrete joints 14 separated by asbestos strips 16 and resting on a bed of sand 18. Thermal expansion in the joint 6, which includes a rolling bearing 5, is thus spread over the overall length of the joints 14, which are individually bonded to the members 7, to a figure below that productive of cracking in the asphalt covering 15. The roadway is constructed from scaffolding comprising a torsionally rigid box girder 19 supported on a roller mounted gantry 21 at one end and by trestles 25 over subsequent columns 1, the box girder 19 having transverse cross bearers 20 enveloping substantially half of the roadway on each side and providing support for shuttering. The roadway is constructed in sections of two cantilever sections 2, 2<SP>1</SP> followed by a suspended section 3, then the box girder and cross bearers are moved forward by hydraulic jacks to permit the construction of subsequent spans.

Title: A new or improved construction of building partitions
IPC: E04B2/74
Filed: 1948-08-23
Abstract: 652,071. Partitions. BEAN & CO., Ltd., J. H. and KNOTHE, H. Aug, 23, 1948, No. 22211. [Class 20(iv)] In a hollow internal partition for buildings of the type consisting of two spaced substantially parallel faces, 1, 2, each comprising lining boards secured in edge to edge relation, with or without gaps between the edges, by one or more cover strips 3 covering the adjacent edges of the boards on one side and devices 6 which usually pass between the adjacent edges of the board to attach the boards to the cover strips, the frames being held at a fixed separation by connecting means 4, 5 engaging the cover strips, the cover strips are wholly on the outside of the lining boards and are of channel form with the free ends of the. arms of the channel bent outwardly to form flanges, the flanges seating on the outer faces of the lining boards with the mouth of the channel directed towards the outer faces over the adjacent edges of the boards, cover strips 8 cover any horizontal joints. The partition is located on the floor and ceiling by bars 10 at each face having one web 11 secured to the floor or ceiling and the other web 12 lying against the outer surface of the face. and engaging in slots 13 cut in the ends of the cover strips. As shown the ceiling is lined with insulating boards 20, and cover strips 21 of top-hat section, the channel portions being cut away at the ends so that the flanges 22 rest on the bars 10. The space between the faces may be filled or partly filled with heat or sound insulating material. The partition is readily dismantled, and the separation of the faces readily varied, e.g. between 2 and 12 inches. The device 6 is shown as comprising a bolt and washer with a spiral spring surrounding the bolt and acting between the washer and the base of the channel of the cover strip.

Title: Improvements relating to transmission systems comprising a hydraulic torque converter
IPC: F16H47/06
Filed: 1957-07-12
Abstract: 851,064. Electric control systems. DAIMLERBENZ A.G. July 12, 1957 [July 12, 1956], No. 22251/57. Class 40 (1). [Also in Groups XXIV and XXXIV] Relates to a motor car change-speed transmission having an engine powered shaft 10 driving through an electromagnetically controlled clutch 48 to the pump 12 of a hydrodynamic torque converter, the turbine 14 of which transmits torque through gear trains 16, 122 to the input shaft 120 of a constant-mesh change-speed gear, engagement of an electromagnetically controlled bridging clutch 51 bypassing the torque converter (see Group XXIV). A control circuit for the gearing comprises a generator 33 driven from the driving shaft 10 and producing a voltage proportional to speed which is applied to the coil 35 of a three-position switch 41. A second generator 34, also producing a voltage proportional to speed, is driven from the input shaft 120 of the changespeed gear, and feeds current to a second coil 36 of the three-position switch. On starting the car from rest, the generator 33 is driven by the engine and conditions the switch to the position shown so that an accumulator 46 is connected through a contact 43 to the torque converter clutch 48, which is accordingly engaged. Drive then passes through the torque converter 12 &c., to the shaft 120 which rotates and drives through the change-speed gearing to the road wheels of the car. As the speed of rotation of the shaft 120 increases, the generator 34 applies potential to the coil 36 of the three-position switch 41. When the speeds of the shaft 10, 120 are synchronized, the potential applied from the generator 34 to the coil 36 is sufficient to move the switch 41 to an intermediate position B, so that the accumulator 46 is no longer connected to the clutch 48 and the clutch is therefore disengaged, but is connected through a contact 44 to the bridging clutch 51, which accordingly engages without shock. The generator 34 has a compound characteristic, so that if the speed of the shaft 120 becomes excessive, the potential applied to the coil 36 moves the switch 41 to a third position C, when the accumulator 46 is no longer connected to the bridging clutch 51, which accordingly disengages, but is instead connected through a contact 45 and a line 55 to a coil 54 to apply a brake 13 to the pump 12 of the hydrodynamic torque converter. Hydrodynamic braking is thus effected.

Title: Improvements in and relating to the spinning of artificial threads, filaments, fibres, films and the like
Inventor: COLES WALTER VALENTINE
IPC: D01D5/06
Filed: 1955-08-03
Abstract: <PICT:0789691/IV (a)/1> Obnoxious gases, e.g. hydrogen sulphide, produced in the manufacture of regenerated cellulose filaments and like products by the viscose process, are collected by passing the freshly formed products upwards through a stationary vertical tube with a concurrent stream of coagulating liquid, the tube having at the discharge end a stationary, partially enclosed chamber provided with an outlet for the liquid from the chamber directed downwards and so shaped as to cause the liquid leaving the chamber to draw gases from the chamber and entrain them with the liquid.  The term "partially enclosed" means that the chamber has one or more relatively small openings to the atmosphere, insufficient to allow escape of the gases but sufficient to allow air to be drawn into the chamber by the entraining action of the liquid.  Fig. 1 shows a section through a suitable spinning chamber.  The freshly formed filaments 16 pass up the spinning tube 1 in a concurrent stream of coagulating liquid, through a slot 7 in disc 4 and through the thread guide 6 in cover 5 to further treatment positions or a collective point.  The coagulating liquid welling up into chamber 9 flows by gravity through outlet 10, extension pipe 13, funnel 12, exit 14 and pipe 15, maintaining a liquid level in the chamber shown by the dotted line.  As it passes from pipe 12 to exit 14 a suction is created; gases are drawn from the space above the coagulating liquid in chamber 9 through outlet 11 and are entrained in the liquid, which passes through pipe 15 to a quiescent zone where separation takes place.  These gases comprise air drawn through the thread guide 6 and slot 7 in disc 4 and also gases, e.g. hydrogen sulphide, formed by interaction of the viscose and the coagulating liquid, which are carried up tube 1 either in solution or suspension in the coagulating liquid and given off in chamber 9.  Fig. 2 is a plan view of the enclosing disc 4, showing slot 7 and a hole 8 used to position the disc by fitting over a peg (not shown) a member 2.  Specifications 504,132, [Group IV], and 782,585 are referred to.

Filed: 1966-05-19
Abstract: 1,108,124. Electric resistance heating. ROLLS-ROYCE Ltd. 19 May, 1966, No. 22290/66. Heading H5H. [Also in Division F1] A temperature reponsive device comprises inner and outer casings 25, 23, an electric heating element 27 disposed in the space 26 between the casings which is filled with insulating material and a temperature sensing device in the inner casing which controls the supply to an electric heater to prevent overheating. The sensing device may be a metal bar of lower coefficient of expansion than that of the casing 25 or a Pt resistance wire connected to a Si rectifier. The device is mounted near a gas turbine air intake (see Division F1) and controls cyclically and continuously energized deicing heaters disposed between neoprene layers on the intake surface. The thickness of insulation and connection of the heaters with the element 27 produce a temperature difference between the casings proportional to that between the intake surface and one deicing heater.

[Class 41] [Also in Group IV] Compounds containing double carbon linkages are produced by reduction of acetylene or its non-metallic organic derivatives containing a triple carbon linkage with zinc and aqueous alkali in the cathode chamber of an electrolyzing vessel separated from the anode chamber by a diaphragm. Zinc formed at the cathode is removed by a stirrer or stripper. The cathode itself may be constructed as a stirrer and of metal yielding the zinc in active form, e.g. Zn, Fe, Ni, Pb, Cd, or their alloys. The amount of zinc regenerated may equal that used up or may be greater, when the electrolysis can be periodically discontinued. In one example, vinylacetylene is led through the cathode chamber of a bath filled with a suspension of zinc dust in 10 per cent caustic soda to yield mainly butadiene.

Title: Improvements in polishing machines
IPC: B24B19/00
Filed: 1920-07-29
Abstract: 167,084. Rogers, F. H., (Simmons Hardware Co.). July 29, 1920. Roller apparatus. - A machine for polishing knives comprises a buffing-roll A, Figs. III, IV, and VI, formed of radially-slit flexible e discs 3 threaded in groups upon a spindle 1. Between the groups are interposed washers of less diameter than the discs, and the whole are clamped between a collar 4 and a nut 5 on the spindle 1. Bearings 2 of the spindle 1 are carried on pivoted arms 69, which are simultaneously raised or lowered by screws 73, bevel-geared to a handrotated spindle 76. The handles of knives K are clamped between plates 15, 16 of a work-holder; yielding material, such as felt 18 and rubber 19, is interposed between these plates. A knife-holding carriage comprises spring arms 10 secured to a square part 9 of a shaft 7, which is rotatably mounted in long arms 23 pivoted at their lower ends 24. Each holder is detachably secured to the carriage by screws 13 pivoted at 14 to the arms 10, and can also be secured in a reverse position so that the opposite sides of the knives can be buffed without removing them from the holder. Cranks 51 on a shaft 50 and connecting- r( ds 25 impart to the arms 23 and hence to the holders a motion towards and from the roll A. Four pins 26 fitted to each end of the square part 9, engage guides 29, 30 during the reciprocation of the carriage. As the carriage is withdrawn from the roll, one of the pins 26<a>, Fig. X, contacts with an abutment of a lever 27 and is caused to move upwards in a circle with the pivot 28 of the lever 27 as centre, thus causing a partial turning of the carriage about its axis. The pin 26<b> moves in the direction indicated, and the pin 26<c> enters a recess 32. On the forward movement of the carriage, the pin 26<c> contacts with a camsurface 30<1> and completes the turning of the carriage through a right-angle. Thus, after each strolce, a fresh set of blades is brought opposite the polishing-roll. A pawl 34, engaging a ratchetwheel 33 on the shaft 7, prevents the carriage from turning while in its operative position. The roll A is belt-driven from an electric motor M, and in turn rotates, by means of belts, a shaft 40 and a pulley wheel 44, which drives a shaft 45 through the medium of a clutch C operated by a hand-lever 48. The shaft 45 is geared to the shaft 50 and also carries a. crank 68, which imparts an axial traverse to the roll A through the medium of a connecting-rod 67, a bell-crank 65, 63, a connecting-rod 62, and a shifter lever 60, the forked end of which engages a collar 58 mounted loosely between collars 59 rigidly secured to the shaft 1. The front of the machine is permanently closed by a plate 77, Fig. III, and, when working, a plate 78 hinged to the former can be raised and held in position by a spring catch 79.

Title: Improvements relating to the manufacture of rubber-like substances
IPC: C08G63/91
Filed: 1945-09-03
Abstract: Highly polymerized esters of di-alkylol arylamines of the general formula HO-(CH2)n-NR-(CH2)nOH, where R is an aromatic radical, with dicarboxylic acids of the series HOOC-(CH2)n-COOH, n and m being integers greater than 1 (see Specification 572,671) are incorporated with a polymer of formaldehyde, e.g. paraformaldehyde and the mixture heated to yield an insoluble and infusible product.  An acid catalyst may be present, e.g. d-camphor-10-sulphonic acid which may have been used for preparation of the polyester.  Admixture of the ingredients may be effected by milling, masticating or by mixing paraformaldehyde with a solution of the polyester and evaporating the solvent.  Inert fillers, e.g. carbon black, may also be added. Suitable starting materials for the polyesters are N-phenyl-diethanolamine, and glutaric, sebacic or adipic acid. The products have increased toughness, hardness, elastic recovery and resistance to hydrolysis, decreased solubility in solvents and no plastic flow.  In examples: (1) highly polymeric N-phenyl diethanolamine adipate was compounded with 0.5 per cent by weight of paraformaldehyde on a roller mill, and heated in a steel mould under 2 tons/sq. inch at a temperature rising from 96 DEG  to 145 DEG  C. in 40 minutes.  The cooled substance was swellable, but not soluble, in chloroform and did not melt at 250 DEG C.  Example (2) is similar, but employs 2.5 per cent of paraformaldehyde and 25 per cent of carbon black.
