Title: Improvements in and relating to closets
IPC: A47K11/03
Filed: 1932-02-20
Abstract: 395,071. Dry closets ; tipping-basin closets ; indicating liquid-levels. JACKSON, E. L., 34, High Holborn, London, and CHRISTOPHER, S. A., 52, Meadway, High Barnet, Hertfordshire. Feb. 20, 1932, No. 5158. [Class 26.] In a closet of the kind having a vessel to receive the sewage when a pan or other primary receiver is tilted or otherwise moved, and means for delivering a quantity of liquid on to the bottom of the pan when the latter is moved from normal position to the sewage-delivery position and back again, the said means are rigidly secured to the pan. The pan 24, Figs. 1 and 3, which comprises a base-member 23 having a bib 26 extending through a gap 25 in the wall 24, is secured to a hinged seat 1 resting upon a casing 3, and the secondary vessel 7 rests upon a vessel 13 with which it communicates by an overflow device 8 closable by a stopper 9. In one form, a second wall 27 shaped as shown, extends about the wall 24 forming a second chamber 28 communicating with the pan by means of an aperture 29 opposite the gap 25. An apertured cylindrical chamber 32 arranged with its axis parallel to the axis about which the pan is mounted, communicates with the chamber 28 by means of pipes 31 carried by the pan, and in the normal positions of the parts, is immersed in the liquid in the vessel 7, a perforated shield 11 preventing the entrance of solid matter. When the seat is tilted the contents of the chamber 32 are discharged into the lower portion of the chamber 28, and on the return of the seat, enter the pan through the aperture 29 and cover the base 23 to a height determined by the upturned edge 30 of the bib 26. In another form, Fig. 5, when the seat is raised, liquid enters chambers 37 carried by the pan from a chamber 33 formed about the pan ; when the seat is lowered, this liquid enters the pan by way of pipes 40, 41. In another form, Fig. 8, the chamber 33 supplies the pan bv pipes 38, a chamber 39 and pipes 43. The height of the liquid within the overflow-vessel 13 is indicated by a float 15, Fig. 1, or by the arrangement shown in Fig. 4, 22 being a floatcontrolled indicator operating in a hole in the fixed portion of the closet-seat. The vessels 7, 13 may be arranged side-by-side, or on the same level or alternatively, the vessel 13 may be dispensed with, the vessel 7 discharging directly into a drain. Specification 358,544 is referred to in the Provisional Specification.

Title: Improvements in Thermal Electric Relays and Circuit Controllers.
Inventor: GRAHAM EDWARD ALFRED
IPC: H01H37/48
Filed: 1917-04-16
Abstract: 111,420. Graham, E. A., and Rickets, W. J. April 16, 1917. Electric switches.-In thermal switches having the contacts carried by a frame a, b, y, z, a thermal sensitive member such as the rod c being placed between the narrow ends of the frame so that, by its expansion or contraction, the circuit is controlled, the contacts g, h are mounted on levers d, e integral with and at the centres of the long sides a, b of the frame. The lower ends of the levers bear on an adjustable abutment x. When the rod c expands, the centres of the sides a, b are brought inwards, this movement being multiplied at the points where the contacts are mounted, the sides of the abutment acting as fulcra for the levers d, e. The rod is sensitive either to a heating-coil i which surrounds it or to the temperature of the surrounding medium. As shown, the rod carries the narrow ends of the frame, but these ends may be carried by blade springs mounted on the base; the rod may be arranged to slide in supports at the ends of the rod. The switch may be used to short-circuit the heating-coil, which is included in a lamp circuit thereby obtaining a constant raising and lowering of the light for flash-light signs. The switch may also replace the electro-magnetic relay e in the battery-charging system described in Specification 15769/13, the coil i replacing the coil of the relay.

Title: A method of obtaining a reversible functional compoundage of engines of high thermal efficiency and high pressure compressors
IPC: F02B41/06
Filed: 1921-02-16
Abstract: 159,185. Franchimont, E., and Cesar, V. Feb. 16, 1920, [Convention date]. Void [Published under Sect. 91 of the Act.]. Compound and multiple - expansion engines.-Steam and internal - combustion engines of high-thermal efficiency, and high-pressure compressors, are worked so that the mechanical actions producing violent detrimental accelerations and retardations are brought to bear upon an idle shaft, normal forces being applied to a second shaft from which power may be taken in a regular and adjustable manner. The energy corresponding to a motor energy diagram, e.g. that of a Diesel engine, Fig. 1, is transferred to an idle running combined motor and compressor having a diagram such as Fig. 2, and a powersupplying motor with a diagram such as Fig. 3. At the point E<1> in the expansion of the motor', Fig. 2, the fluid is discharged at constant pressure E<1>B<1>G<1> to the power-supplying motor, Fig. 3. In the idle motor, Fig. 2, the resisting work of compression A'B'C' of the air and the pumping of the burnt gases at constant pressure E<1>B<1>G<1> are compensated for by the work produced by combustion C<1>D<1> and expansion of the burnt gases D'E'. A slight injection of cooling-liquid vaporizable by the burnt gases can be made at the end of the expansion resulting in a mixture of burnt gases and steam more or less superheated. The two engines may be coupled if the two-stroke engine, Fig. 3, runs at half the speed of the four-stroke engine, Fig. 2. To avoid undue size of cylinders, the compressor section of the diagram G<1>K<1>H<1>A<1>L<1>B<1> may be divided into two parts, one of which is realized in a Diesel engine running light and the other in a special compressor worked thereby. The compressor may be a turbine, and the compressed air fed momentarily to a tank. By a reversal of the process, the compression of fluid can be carried on in stages, the higher stages running light. In an arrangement applied to a locomotive, the lightrunning Diesel engine has a speed four times that of the driving-axle, and supplies a doubleacting two-stroke motor directly connected thereto. During braking the motor acts as a compressor and charges a tank for starting.

Endless-chain machines; endless-chain conveyers; scrapers, construction of.-Relates to mining machines, more particularly to machines of the long-wall type of the construction shown in Specification 211,876, and comprises a frame, a cutter chain having cutter bits thereon mounted on the frame and movable longitudinally thereof adapted to form a substantially horizontal kerf in the material to be mined, a convever mounted to the rear of the cutter chain and .extending parallel therewith, and means at the butt end of the machine for forming a substantially vertical kerf in advance of the horizontal kerf in the material to be mined. A frame A carries a cutter chain 12 having the usual bits 14 and extending over the sprockets 8, 10. The conveyer comprises T-shape members 25 secured to chains 26, 27 trained over idler sprockets 18, 19 and driving sprockets 21, 22, and is raised at the delivery end to deliver into cars B from the conveyer plate 17. A disc shaft 28 journaled on the base carries worm 30 meshing with worm wheels 31 freely movable on threaded feed-in bars 32. These latter carry nuts 30a adapted to be locked to the wheels 31 by pins 31<a>, and are positioned against removable jacks 34 at the rear while their forward ends project through openings 35 in the frame. The bars 32 are arranged in pairs so that one bar of each pair may be put ready in forward position while the other is advancing the machine. As the machine cuts under the coal and advances into the kerf formed by the chain 12, the coal falls on to the housing 7 and is pushed on to the conveyer plate 17 and delivered into cars. Hydraulic jacks 70 supporting the roof are arranged' in two rows in staggered relations, those in rear being loosened and moved forward of the others as the machine advances. The chain 12 is driven from a motor 39 through a shaft 40 and worm 41 and the conveyer chains are driven from a stub-shaft 46 through chains 55, 60 and gears 54, 56. The shaft 28 is rotated from the same stub-shaft through a chain 50 to operate the feedin bars 32 and vertical cutter Y, or the latter may be driven from a separate power source. The cutter Y is supported on the frame A by a housing and support 80 riveted to a support 81 on the frame A. Plates 82, 83 are spaced apart by filler blocks 84 - - 87 and bolted together by bolts 88 so as to receive the chain 97 carrying the bits 98 between them, the block 87 supporting the cutter chain which travels downwardly therealong. A chain 99 connects a sprocket 100 on the shaft 28 with a sprocket 96 mounted on a shaft 91 which also carries the cutter chain drive sprocket 95, so that the cutter chain 97 is driven from the motor 39. The plates 82, 83 and chain 97 are in advance of the chain 12 so as to cut a vertical kerf in advance of the horizontal kerf and the cutter Y overhangs the chain 12 and conveyer so that the latter removes cuttings from it. A guard plate 101 is provided for the chain 97 and is secured to the plate 82 by means of a bracket.

Abstract: 1286021 Golf practising device R GLADSTONE 19 April 1971 [6 Feb 1970] 5678/70 Heading A6D [Also. in Division G1] The velocity of the head of a golf club when swung by a player can be measured directly by connecting a chassis f of an accelerometer by fastening means a, b, c, y to the shaft z of the club, the accelerometer comprising a body h of known mass mounted on the chassis springs g1, g2 for movement relative to and parallel to the golf club shaft against the action of the springs; and indicating means mounted on the chassis and adapted to indicate the extent of any movement of the body h towards the golf club head in excess of a predetermined minimum. The fastening has a duralumin strip a formed with a shallow V-shaped groove to locate shafts of various thickness together with a spring wire strap b tensioned by a screwed rod c and nut y. The chassis f is bolted or riveted to the strip a being enclosed by a perspex base and cover. The characteristics of the springs g1, g2 are such that when they oppose centrifugal force towards the club head due to swinging the club, the angular movement transmitted to a pointer k when a bent semi-rigid arm i reaches the side of a sector n gives an indication of velocity on a scale j. The maximum reading is held by the friction of light springs bearing on vee pulleys on sleeves carrying the pointer k and sector n and a button q contacts a spring strip r, s to return the sector n until the pointer k contacts a stop x, arranged so that only velocities above a desired level are indicated to allow calibration for maximum use of the scale circle. Suitable dimensions are suggested.

Title: Preparation of shaped elastomers from isocyanate modified polymers
Inventor: SHRIMPTON RONALD HORACE
IPC: C08G18/00
Filed: 1954-02-27
Abstract: A moulding compositin comprises a plastic dispersion of solid particles of a reaction product of a diisocyanate and a polyester, polyesteramide or polyalkyleneglycol dispersed in a liquid reaction product of the same kind.  This paste or dough can be shaped by the usual methods to give products which have sufficient strength to be used in tyre-building operations.  The solid particles or crumb is prepared from partially cross-linked reaction products, the liquid dispersion medium being uncross-linked and a cross-linking agent being incorporated into the dispersion.  Alternatively the liquid component may be prepared in the presence of a cross-linking agent provided an inhibitor is also present.  The liquid comprises 10-150 per cent, preferably 80-120 per cent by weight of the crumb.  In examples: (1) a crumb was prepared from the reaction pruduct of naphthalene 1,5-diisocyante and polyethylene terephthalate by cross-linking with water, and disintegration until 90 per cent passed through a 30 mesh per inch sieve.  The crumb was mixed with 0.8 per cent water and 100 parts dispersed in 100 parts of a similar reaction product in the liquid state.  The resulting dough was shaped at 100 DEG  C. for 5 minutes at low pressure and subsequently moulded at 500 p.s.i. for 45 minutes at 150 DEG  C. with an after cure of 24 hours at 110 DEG  C. or 72 hours at 70 DEG  C.  Figures are given for tensile and tear strengths and elongation.  Examples 2 and 3 are similar but use 1.4 butane diol and 1.4 butene diol respectively as cross-linking agents.

Abstract: 1530637 Pistons KARL SCHMIDT GmbH 13 Feb 1976 [24 Feb 1975] 05843/76 Heading F2T A light alloy piston 1 for a diesel engine with a head 2 provided with a recess in the form of a combustion chamber 4, and possibly also a fuel-guiding channel 3 and valve pockets (not shown), is characterized by a hard anodized layer in selected regions, namely those which are relatively less highly stressed in use by gas and inertia forces. Where appropriate, the hard layer is present adjacent to the fuel guiding channel 3 but absent from regions adjacent to all edges of the valve pockets and certain edges of the combustion chamber 4. The hard layer is said to seal the piston head and to give protection against corrosion and oxidation; omission in highly-stressed areas avoids stress-cracking there. In an embodiment, the anodized layer has a hardness of between 450 and 550 HV, a thickness of 35-80 microns and consists of pure alumina with a covering layer of alumina and aluminium hydroxide.

Title: Improvements in or relating to generating oscillations
IPC: H03K3/78
Filed: 1948-02-27
Abstract: 654,684. Pulsing carrier frequencies; generating oscillations. DEPARTMENT OF COMMERCE, DIRECTOR OF THE OFFICE OF TECHNICAL SERVICES OF. Feb. 27, 1948, No. 5934. Convention date, Jan. 11, 1944. [Class 40 (v)] Oscillations are generated by shock-exciting a resonant circuit, then suppressed by applying inverse feedback to the circuit, so that the oscillations begin and cease almost instantaneously and remain constant in amplitude intermediately. In Fig. 1 a positive gate pulse applied to the cathode of a valve 10 renders it non-conducting and shock excites through its resonant anode circuit a transformer-coupled balanced bridge circuit comprising a piezo-electric crystal 34, which circuit resonates with substantially pure sine waves from which shock has been eliminated due to its balancing, and with low decrement due to the series circuit of the valve 10 and its anode circuit being non-conducting. The oscillations are applied through amplifier valves and taken off from an output 56 and are further passed through a valve 59 to develop across a variable resistor 82 an opposing feedback to the valve 10 and crystal circuit, ineffective as long as valve 10 is blocked, but, on the gate pulse terminating and the valve 10 conducting, strongly damping or suppressing oscillation in the crystal circuit. In Fig. 2, a valve 90 at near cut-off due to the cathode resistor 92, is connected in series with a bridge circuit comprising three condensers 101, 102, 104 and a piezo-electric crystal 106, a diagonal tapped high resistance 108 balancing the bridge. A positive gate pulse applied to the cathode of a succeeding valve 137 (not shown) is fed back to the grid of valve 90 through a lead 150 to energize the valve and excite sinusoidal oscillations in the crystal bridge, which are maintained due to the valve 90 resistance being low and are passed to output amplifiers. On the positive gate pulse ceasing the valve 90 is driven to near cut-off so that its high resistance is between the condensers 101, 104 and the high resistance 108 is in series with the crystal, and the oscillations therefore damped. As before, the oscillations produce in part through the amplifier valves and valves 137, 90 an opposing feedback to the bridge suppressing oscillation.
