Title: Process and apparatus for dry cleaning
IPC: D06F43/08
Filed: 1935-08-21
Abstract: <PICT:0461963/III/1> In a dry-cleaning plant in which the cleansing liquid is filtered, pure liquid is recovered periodically from the soiled liquid by boiling the latter in contact with the filter to distil it, and the agitation produced serves to shake solid accumulations from the filter, this solid being present in the fluid as a filter aid. The liquid is pumped from the cleaning apparatus and delivered through tubes 35 and 37 into the filter chamber 5.  The liquid passes through the filter bags 7 the interiors of which are connected to a manifold 9 connected to the return pipe to the cleaning apparatus.  When it is desired to distil the liquid, steam is passed through a coil 13 to heat the liquid in chamber 5. The boiling liquid dislodges solid matter from the filters 7 and vapour passes through aperture 28 to tank 4 where it is condensed by cooling water coils 22 and 27.  The cleansed liquid is returned to the cleaning apparatus through valve 47, When the apparatus is being used simply as a filter, cooling water may be passed through coil 13 to coagulate impurities and facilitate the filtration.

Abstract: 483,534. Proofing permeable materials. CELA HOLDING SOC. ANON. Aug. 27, 1937, No. 23546. Convention date, Aug. 28, 1936. [Class 140] [Also in Group IX] The process of making pneumatic tyre covers described in Specification 449,588, [Group IX], is modified by subjecting the fabric, after treatment in the contracting and swelling bath, which may contain a wetting-agent, to an alkaline boiling treatment, e.g. by sodium carbonate lye under pressure. A suitable lye contains also soda soap and is used at 115‹ C. under a pressure of 1À5 atmospheres for four hours. The fabric is then washed in hot water, then in cold water, neutralized, e.g. with hydrochloric acid, again washed and dried. Treatment with rubber follows. In a further modification the threads are contracted and swollen before weaving. Before stretching and vulcanizing the impregnated tubes, the borders may be cut off to avoid buckling.

Title: Improvements in or relating to fishing tackle
IPC: A01K85/16
Filed: 1929-08-06
Abstract: 337,479. McLaughlin, F. Aug. 6, 1929. Artificial bait; spinning tackle.-The hook of a fishing bait on being released from its retaining notch is rotated about its shank as axis and assumes a position with the bait exposed. A wobbling device 14 which extends rearwards and downwards is mounted on the front of the bait by various arrangements which permit of a movement of less than one complete revolution. In Fig. 1 the hook is carried in bearing members 4, 5, and a spring 6, attached to the hook and to the member 4, rotates the hook on its release. Alternatively, the spring 6 may be attached to the bait and a projection 9 on the hook which is provided to limit its rotation. In Fig. 4 the rotation is effected by a spring plunger. The plunger stem 11, which is rockable relative to its head 12, is connected to an offset portion 10 of the hook. With the construction shown in Fig. 6 an outward swing of the hook occurs as well as the rotation. A spring 21 carries a plunger 22, which a. spring 24 tends to expel from the recess 23. The end 20 of the shank is hingedly connected to a loop which passes into a hole 18 and is fixed over a brace 19 carrying a wobbler 14. In order to swing the hook, a weight, or the resiliency of the hook itself, may be substituted. In a modification, the hook is mounted on a swinging frame carried under the body. The hook may also be mounted so as to be pulled free of the body when it is released by either attaching it to the main line or to a short fine line wound round the body. The notch for the hook, which also acts as a shield, may be formed in the body of the bait or by a tube projecting from the body, or on a spring passing across the body. The hook may be constructed in two sections connected by a sleeve and the bait may be replaced by a spoon, or a spoon 29 may be attached as shown. A diving device may also be attached to the bait.

Abstract: 686,082. Wrapping-machines. ROSE BROS. (GAINSBOROUGH), Ltd. Sept. 5, 1951 [Oct. 3, 1950], No. 24097/50. Class 94(i) [Also in Group XXX] In a wrapping-machine in which articles 11, e.g., blocks of ice-cream, are transferred in succession from the pockets 12 of an intermittently operated conveyer 13 to the pockets 27 of an intermittently rotating wrapping wheel 28, the transfer being effected while the conveyer is at rest by a reciprocating pusher 24 which passes through the pockets, the pusher is moved during its return stroke in the direction of movement of the conveyer and at substantially the same rate so as to be withdrawn through a pocket of the conveyer while the conveyer is in motion. The conveyer 13 comprises an endless chain passing over a sprocket 14 driven through Geneva mechanism by a main shaft 23. The pusher 24 is integral with an arm 31 which is pivoted to an arm 33 mounted on a shaft 34 and is formed with an extension 37 carrying a pivoted block 38 slidable in a cross-head 39, the arm 33 being pivoted at 41 to the sheave 42 of an eccentric 43 secured to the shaft 23. The cross-head is carried by an arm 44 pivoted at 46 to an operating lever 47 which is mounted on the shaft 34 and carries a roller 48 engaging a groove 49 in a cam 51 on the shaft 23. The arm 44 carries a pivoted guide block 52 slidable in a fixed guideway 53. The Geneva mechanism, the eccentric 43 and the cam 51 are so timed that the conveyer comes to rest as the pusher commences its forward stroke during which the cross-head remains stationary. As the pusher commences its return movement, the conveyer moves to bring the next block 11 to the transfer station and the cross-head is moved by the cam 51 to cause lateral movement of the pusher so that it is withdrawn through the pocket while the conveyer is in motion, the cross-head then moving the pusher once more into registry with the pocket at the transfer station.

Title: Improvements in or relating to frequency divider circuits
Inventor: HUNTLEY KEITH GORDON
IPC: H04N5/06
Filed: 1954-08-19
Abstract: 794,908. Automatic frequency control. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Aug. 19, 1955 [Aug. 19, 1954], No. 24122/54. Class 38 (4). [Also in Groups XL (b) and XL (c)] Fig. 1 shows the application of a pulse frequency-divider to a television wave-form generator in which it is required to produce pulses of the field repetition frequencies from input pulses of double the line repetition frequency. The master oscillator 1 generates pulses of double line frequency, Fig. 2A, which are fed with positive polarity to a two stable state trigger circuit 2 thus producing output pulses at line repetition rate, Fig. 2B. These are fed to a shaping circuit 3 which generates a short pulse coincident with the beginning of input pulses fed to it. The output from shaping circuit 3 is fed to a coincidence gate 4 the output from the gate being used to trigger a flip-flop 5 the duration of the unstable state of which is about 100 microseconds, i.e. approximately a line period. Thus output pulses of duration 100 microseconds are produced from flip-flop 5 and are applied via a further shaping circuit 7 which generates a short output pulse coincident with the trailing edge of each input pulse. The output from shaper 7 is applied to a further flip-flop 8 the unstable state of which has a duration of 20 milliseconds, i.e. approximately one field period, Fig. 2D. Only during the coincidence of a positive pulse from flip-flop 8 and from shaper 3 does the gate transmit an output pulse. In every field cycle one additional pulse is fed to the trigger circuit 2 via the delay device 6 so that the circuit 2 is caused effectively to divide the master pulse frequency from oscillator 1 by an odd number in any field period. The value of this odd number is set according to the duration of the unstable state of flip-flop circuit 8. In order to lock the output frequency to a reference frequency, such as for example the mains frequency, a control signal may be applied to flip-flop 8 to vary the duration of its unstable state in dependence upon the difference between the output frequency of the divider and the reference frequency.

Title: An improvement in or relating to sluice gates
IPC: E02B7/20
Filed: 1926-10-01
Abstract: 283,255. Blakeborough, R. A., (M'Call, G.). Oct. 1, 1926. Levels, regulating.-Control apparatus for a sluice gate by means of which the water level in a conduit served by the gate is maintained at a constant level, and comprising a float arranged to rise and fall with variations in the water level and to put into operation means for moving the gate in the required direction, is arranged so that after a predetermined movement of the float in either direction, of sufficient amount to actuate means for controlling the operation of the gate moving mechanism, the said control means are caused to move bodily with the float so that a predetermined movement of the float itself in one direction operates the control means to initiate movement of the gate back to its original position. A chamber a communicates with the conduit in which the level is to be controlled and contains a float c pivoted to the lower end of a rod d. At its upper end the rod d is pivoted to the end of the short arm of a lever e which carries at the end of its longer arm a contact g operating a reversing switch h which controls the supply of current to the electric motor operating the gate. The pivot seating of the lever e is carried on a bracket i attached to a vertical tube extending through a guide into the float chamber a and enclosing the rod d. The lower end of the tube is provided with a collar j<1> over which extends a stirrup c<1> on the float, the distance between the stirrup and the top of the float being such that a movement of the float can occur in either direction sufficient to cause the rod d to tilt the lever e and change over the switch before the float or stirrup touches the collar j<1>. The switch h is carried by the bracket i, so that on continued movement of the float in one direction, the tube j, the lever e and the switch h all move with the float. When the float, as the result of the operation of the gate and consequent variation of the water level, commences to return to its' original position, it operates immediately to tilt the lever e and change over the switch, thus reversing the movement of the gate. After a determined movement of the float, the tube and its associated parts are also returned and a position is finally reached in which the float regains its normal position in which it occupies such a relation to the tube that the latter is held balanced by counterweights o, whilst the beam is held by the float in a central position in which the reversing switch is neutral.

Abstract: 732,660. Regulating. CITY TANK CORPORATION. Oct. 18, 1951 [Oct. 19, 1950], No. 24343/51. Class 7(6). [Also in Groups XXIX, XXX and XXXI] The throttle valve or fuel contro means 38 of an engine 10, through which a hydraulic pump 14 is power ed to drive a hydraulic motor 16 en countering a wide range of loads, is actuated by a servomotor 34 having pistons 53, 58, Fig. 3, therein res ponsive to the pressure in the hydraulic system, the travel of the larger diameter piston 53 being limited by a stop 50 whilst the smaller diameter piston is capable of being moved independently of the piston 53 beyond the stop 50 by abnormally high pressures in the hydraulic system. As shown the engine 10 of a refuse truck drives through a power take-off 12 a hydraulic pump 14 which drives a hydraulic motor 16 actuating a refuse loading and packing mechanism 22 described in Specification 684,722, [Group XXX], and comprising a chain lift 23 and packer device 27. The engine throttle valve lever 37 is connected through a rod 35 to the servomotor 34 which is connected by a pipe 33 to the hydraulic fluid pressure pipe 15. The servomotor 34, Fig. 3, comprises a sliding piston sleeve 53 in which is slidably arranged a second piston 58 connected to the rod 35 and loaded by a spring 73 acting on a flange 67, the pistons being sealed by packing rings 56, 61. After engaging the power take-off 12, the operation of the engine at idling speed is suthcient to drive the loader 22 when unloaded. On loading thereof, the pressure rise in the line 15 actuates both pistons 53, 58 against the spring 73 to open the throttle valve. After a short travel the piston 53 contacts the shoulder stop 50 and both pistons remain stationary in this position for normal loading of the loader 22. An abnormal load causes a greater pressure build-up in pipe 15 and the piston 58 moves relative to the piston 53 to open the throttle valve further. Specification 545,099, [Group XXX], also is referred to.
