Abstract: 1300729 Rolling mills INSTYTUT METALURGII ZELAZA IM STANISLAWA STASZICA 8 June 1970 [7 June 1969 14 April 1970] 27520/70 Heading B3M A cluster mill incorporates cantilevered work rolls 32, Fig. 12, and backing rolls 40 mounted in a frame 3, the frame being slidably supported by columns 4 in a fixed main housing 1. When the frame is moved along the columns by a cylinder 96 the rolls are axially adjusted. For adjustment of the work rolls towards and away from one another the backing rolls are adjusted, the work rolls being urged against their respective backing rolls so that they follow their movement. The backing rolls are carried in frameworks 132, Fig. 13, which are pivoted at 133. A worm-driven screw adjuster moves the two frameworks to adjust the rolls. One work roll is driven by a control shaft 33 from shafts 13 and 15, and the two rolls are drivingly coupled by pinions 9, 10, 11 and 12 (Fig. 11). Alternatively, the rolls may be driven by separate motors and drive shafts. The work rolls have sleeves which can be removed from tapered supports 30, and the backing rolls can similarly be removed from the frame. To remove the backing rolls, tapered shafts 135 and 136 are moved axially towards each other out of their bearing cups 130 by a worm wheel 141, the rolls then being removable. A similar arrangement is shown in Fig. 9, but the backing rolls, and hence the work rolls, are adjusted by eccentrics 116. The eccentrics are coupled to frames 115 in which the backing rolls 40 are supported, the eccentrics being rotatable to move the frames and rolls. A driving shaft 78 (Fig. 11) is coupled by screw adjusters and levers to the two eccentrics such that rotation of the shaft leads to adjustment of the rolls. A further embodiment (Figs. 1-8, not shown) is basically similar to the above embodiments.

Patent GB-1075426-A (GB)
Title: Method of bonding
Inventor: HARRIS ROY JOHN
IPC: C08J5/12
Filed: 1963-07-12
Abstract: A metal surface is bonded to a rubber composition comprising an interpolymer of ethylene and an alpha-olefin with or without one or more copolymerisable compounds serving to confer unsaturation on the unvulcanised interpolymer by mixing the interpolymer in the unvulcanised state with an organic peroxide which liberates a mineral acid when heated, applying the mixed composition to the metal surface to be bonded, and heating the composition to a temperature in excess of the temperature required to cause said peroxide to liberate a mineral acid, to effect vulcanisation of the interpolymer and bonding of the composition to the metal surface.  The peroxide may be tri- or tetra-chloroditertiary butyl peroxide.  The compositions may also p contain carbon black and sulphur.  In examples the polymers are bonded to mild steel; they may form liners for vessels containing corrosive fluids.

Title: Means for creating a controlled consumption of lubricating oil in injection type internal combustion engines
IPC: F01M1/10
Filed: 1957-09-03
Abstract: 867,711. Fuel injection pumps. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. Sept. 3, 1957 [Sept. 29, 1956], No. 27734/57. Class 102(1). [Also in Group XXXIV] The inlet chamber of a fuel injection pump is connected to the engine lubricating oil system during part of each cycle of operation. As shown in Fig. 1, a duct 12, leading from a groove 13 in the cylinder bore to the inlet chamber 5, and a duct 11 from the cylinder bore to the lubricant channel 7 are interconnected during reciprocation of the plunger 4 by a groove 14 and recess 15 in the plunger so that a small quantity of lubricant is forced into the chamber 5. In a modification the groove 14 is tapered and of varying depth so that the quantity of lubricant forced into chamber 5 varies according to the angular setting of the plunger 4 and hence the speed of the engine. In a further modification a restriction in the fuel inlet to the chamber 5 creates a greater depression therein at higher speeds whereby a larger quantity of lubricant will flow into the chamber. In another arrangement the flow of lubricant to the chamber 5 is controlled by a passage in the actuating cam-shaft of the pump, which passage connects the lubricating system to the inlet to chamber 5. The invention is for use with dual fuel injection engines ; when an engine is to be run with fuel oil the supply of lubricant to the pump is cut off. The stated object of the invention is to ensure that by increasing the lubricating oil consumption constant replenishment will prevent deterioration of the oil when running on petrol.
Patent GB-408287-A (GB)
Title: Hinge mounting of doors, particularly automobile doors
IPC: B60J5/04
Filed: 1932-10-06
Abstract: 408,287. Door buffers; hinges. HAMILL, W. W., Beechcroft, Four Oaks Road, Four Oaks, Sutton Coldfield. Oct. 6, 1932, No. 27758. [Classes 65 (i) and 65 (ii).] A buffer for vehicle doors, adapted also to prevent rattle, comprises a block of rubber shaped to key into a cavity in the hinge post of the door frame or the hinged edge of the door so that when the door is closed it exerts pressure on its hinged edge in the plane of the door to take up any clearance. The hinges of the door are adapted to yield to a limited extent in a horizontal direction in the plane of the door under the reaction of the rubber block, and may be of the rising type to counteract the opening tendency due to the pressure of the rubber, the lowest part of the cam surfaces being horizontal to avoid resistance to the take-up movement of the door. Fig. 1 shows the buffer 9 keyed into a cavity in a wooden door or frame member 12, the rubber being formed with a cavity 11 into which it can spread when deformed. In the case of metal doors or frames, the metal is formed to provide a socket of shape corresponding to the rubber. If projecting hinges are used, the hinge leaves may be sufficiently resilient to allow the door to be moved in its own plane under the pressure of the rubber to take up any clearance ; alternatively, one of the hinge eyes may be slotted, as in Fig. 4, to allow such movement, or one of the hinge plates may have an additional joint, to act as a link supporting the door. In the case of resilient hinge leaves, the hinge knuckles may be provided with stops which operate to bend the leaves when the door is nearly closed ; the projecting part of the hinge leaves may be tapered in thickness towards the hinge pin. According to the Provisional Specification, the rubber block may be replaced by a spring- pressed plunger, which may, if desired, be provided with a plurality of concentric springs ; in another modification one or more spring tongues may be pressed up from one of the hinge leaves to engage the other. The rubber block or spring plunger is preferably incorporated in one of the hinge leaves. The rubber buffer may comprise a headed portion and a tapered waist or constriction seating in a corresponding part of the hinge leaf. The device may be applied to the door sill to act upwards, the door having a co-operating antifriction roller.

Bed frames are made from structural elements as shown in Fig. 3 of extruded or rolled aluminium or an alloy thereof or a thermoplastic synthetic resin, which may have two grooves 6 one in each side wall 2 and 3. The elements are joined together by inserting die-cast plugs 12 into abutting compartments 5 and the legs 15 are attached by passing the headpieces 18 of bolts 16 into compartments 5 so that the shanks 17 extend through the undercut portion and engage lugs 19 of the legs 15. The springing of the bed frames is provided, by rubber webs secured to the frame by inserting hooks, which are attached to the webs, into groove 6, or by linked or chain type springing with hooks engaging the groove 6. An adjustable bed is formed (Fig. 4) by attaching the legs 23 to the bed frame 26 using bell crank levers 25 which are pivotally mounted on the upper ends of each leg 23 and carry stirrups 30 having a T-piece slidably engaged in the lower compartment 5 of the associated rail length 27. When the bed is raised to the dot-andpick position the upwardly extending edges of the levers 25 are seated in the groove 6. The bed may be locked in intermediate positions by a screw bolt carried by each stirrup 30. Attachments can be secured to the bed frame for supporting plasma bottles and other surgical or medicinal equipment. These attachments are illustrated in Figs. 6, 7 and 8 (not shown) as substantially V- shaped members with flanges engaging groove 6 and slot 8. Fracture boards may be slung between the sides of a bed by hooks engaging in grooves 6 and when using structural elements with two grooves 6 bracing legs may be attached to the inwardly directed groove 6.

Abstract: 827,839. Underpinning buildings. PYNFORD Ltd. Sept. 28, 1956 [Sept. 29, 1955], No. 27778/55. Class 20(2) In a method of underpinning buildings, shoring piers erected in spaced openings in the damaged substructure, each include at least one pair of load carrying metal shoring plates C<SP>1</SP>, C<SP>2</SP> and J, Fig. 1, held spaced apart by removable spacers G<SP>1</SP>, G<SP>2</SP>, &c., Fig. 3, each consisting of a metal bar fitting with slight clearance between the two shoring plates C<SP>1</SP> or C<SP>2</SP> and J and a number of bolts H which engage with the shoring plate J and are tightened to force the spacer bar G<SP>1</SP>, G<SP>2</SP>, &c. into engagement with the shoring plate C<SP>1</SP>, C<SP>2</SP>, whereby, (when the remaining portions of the damaged substructure have been removed) by removing and replacing such spacer bars in turn, metal reinforcing rods L can be inserted laterally from the front or back of the wall between the two shoring plates C<SP>1</SP>, C<SP>2</SP> and J into the appropriate positions for subsequent embedding in concrete to form the final beam-like underpinning structure. The shoring plate C<SP>1</SP>, C<SP>2</SP> is divided by one or more slits C<SP>3</SP> to enable the rods L to be passed down between the supporting pins D of the shoring piers. After the beam-like underpinning structure, which is denoted by the broken line a-a, has been completed to take the load, the spacer bars G<SP>1</SP>, G<SP>2</SP> &c., with or without the shoring plates C<SP>1</SP>, C<SP>2</SP> and J can be removed. Instead of providing the spacer bars G at the top of the shoring piers they may be provided at the bottom or at the top and bottom of the shoring piers. Reinforcing rods L<SP>1</SP>, L<SP>2</SP> can also be provided, and additional reinforcing rods L<SP>3</SP> of smaller diameter can be flexed to enable them to be pushed end first between the supporting pins D from the front and back of the wall. After the reinforcing rods have been inserted into position, supporting piers may be erected around the rods to take the load and thereby permit the shoring'piers or parts thereof to be removed, such supporting piers being embedded with the reinforcing rods in the final beam-like structure which can then extend for the full height of the original set of openings in the substructure.

Title: Improvements in or relating to centrifugal separators
IPC: B04B1/18
Filed: 1936-10-13
Abstract: 483,239. Centrifugal separators. FAWCETT, H. W. Oct. 13, 1936, No. 27787. [Class 23] A centrifugal separator has a bowl 1 with peripheral discharge apertures 2 controlled by an hydraulically operated sleeve 5 which is moved axially to bring the openings 6 into register with the apertures 2. The sleeve has rings 7, 9 between which works a ring 11 secured by a lock-ring to the bowl and which acts as a piston when liquid is supplied through the passages 13, 14. Cross-binding or sticking between the moving and the fixed parts is prevented by the provision of inter-engaging screw-threads 20 on the outer side of the bowl and the inner side of the sleeve. The threads have a coarse pitch and force the sleeve to move uniformly. Instead of providing the screw-threads 20, the end of the ring 7 and the bowl 1 may be provided with screw-threads 23, 22 respectively. In a modification, a ring 30, Fig. 4, is arranged on the bowl and provided with oblique teeth 31 which engage similar teeth 32 on a replaceable ring 33 secured to the ring 7. The ring 30 rotates while the sleeve 5 moves axially. Specifications 451,251 and 460,362 are referred to. The Provisional Specification states that the parts engaging for the hydraulic operation of the sleeve may be spherically shaped.

Title: Semiconductor devices
IPC: H01L31/173
Filed: 1965-07-01
Abstract: 1,073,460. Semi-conductor devices; lasers. BATTELLE DEVELOPMENT CORPORATION. July 1, 1965 [July 31, 1964], No. 27935/65. Headings H1C and H1K. A light-coupled semi-conductor device comprises a junction diode laser and a light-responsive junction. As shown, Fig. 2, a laser junction 28b having a coplanar photodiode junction 49b, 50b located at each end is produced by masking an N-type GaAs body 26b, doped with Te, with an evaporated layer of silicon monoxide using a photo-resist technique and diffusing-in Cr to produce semi-insulating regions 53b, 54b. Alternatively Cu or O can be used to produce these regions. The surface of the device is cleaned and masked with a layer of silicon monoxide in which three windows are formed, the two end windows being covered with a thin layer of silicon monoxide to retard the diffusion of impurities. Zn is diffused-in to produce P-type regions 24b, 29b, 32b, the doping level in region 24 being so high that it can be considered to be uncompensated by the Te atoms, while regions 29b, 32b have layers 31b, 34b which are partially compensated with Te. Windows are etched in the mask and Au is evaporated-on to form contacts. Alternatively the lower face contacts may be applied by ultrasonic soldering. Adhesion of the metal contacts can be improved by thermo-compression bonding. Variations are described with reference to Fig. 1 (not shown), in which a device has regions of complementary conductivity type and has the semi-insulating regions (53, 54) omitted, Fig. 4 (not shown), in which the photodiodes are replaced by phototransistors with the collector junctions (49d, 50d) coplanar with the laser junction (28d), Fig. 3 (not shown) in which the device of Fig. 4 has regions of complementary conductivity type, and Fig. 6 (not shown), in which one of the photodiodes is replaced by a reflective layer (70) of Al or Ag. Further variations are described with reference to Figs. 7 to 11 (not shown) in which the light emitted by a laser is amplified by a secondary laser before being applied to the detector junction which may comprise a photodiode or phototransistor. The laser may be anisotropically stressed in an axial direction, Fig. 12 (not shown), or by a bending moment, Fig. 13 (not shown), to increase the polarization of the spontaneous emission in the desired direction and hence increase the stimulated emission. The stress may also be applied to the amplifying lasers and to the detectors, Fig. 14 (not shown), to increase their amplification and absorption respectively. A bending stress may be produced by bonding the device to a bimetallic strip at an elevated temperature at which the strip is flat so that on cooling to normal operating temperatures the strip bends. The required partial compensation of the P- type regions may be achieved by heavily doping with Zn so that the excess Zn is located interstitially and acts as a donor.
