Title: Improvements in bottle closing or filling and closing machines
IPC: B67C7/00
Filed: 1925-01-29
Abstract: 246,262. Chaloner, G. W., and Blaxter, A. P. L. Jan. 29, 1925. Bottling; stoppering.-In a machine for closing milk bottles &c. the bottles are held below a carrier provided with recesses for the reception of the closing discs or caps and the bottles and the carrier are moved together below means which supply the carrier with discs &c. and apply them to the bottles through the recesses in the carrier. The machine may be adapted to fill the bottles as they approach the closure feeding and applying devices. A base 2 supports, a column 1 rotated continuously by a shaft 4 and provided with a platform 5 carrying bottle supports 6 which are engaged by a cam track 47 to raise the bottles 12 into engagement with throats 11 disposed in recesses 10 in a carrier or ring 7 secured to a boss 9 on the column 1. Milk from a tank 24 is supplied through pipes 25 and three-way valves 14 supported by the boss 9 to measuring vessels 26 when spouts 15 secured to the valves are in the position indicated in full lines. When a bottle is placed on a rest 6 it moves aside a spring-pressed lever 21 mounted on the platform 5, the movement bringing a distance piece 20 on the other end of the lever into alignment with rods 16, 17 so that when the rod 17 is raised by a cam track 19 the rod 16 moves the corresponding spout to the position shown in dotted line and the milk in the measuring vessel 26 flows into the bottle, the valve 14 cutting off its communication with the tank 24. As the bottle approaches the closuring devices, the spout is moved to its original position to permit its measuring vessel to be refilled. The bottle and carrier move beneath disc reservoirs 29, which place a disc in the recess 10 just prior to its passage beneath an applying plunger 34 operated by a lever 40 which receives a, sharp knock from a spring-actuated rod 42 controlled by a cam 45 on the shaft 4. The plunger 34 is carried by a plate 35 resiliently supported on levers 37 free to move sideways on their pivots to allow for movement of the carrier 7 during the closing operation, the plunger and its associated parts being mounted on a bracket 31 supported by an independent standard 33. Excessive horizontal displacement of the plunger operates trip gear to stop the machine.

Filed: 1945-10-24
Abstract: 609,034. Manure distributors. ATKINSON, R. L. Oct. 24, 1945, No. 28049. [Class 6(i)] A manure distributer comprises a base, movable intermittently towards one end of a vehicle, a plurality of tines rotatably mounted on two or more shafts extending across the vehicle and a plurality of impellers for broadcasting the manure. As shown mounted on a tractor vehicle body an endless belt C is mounted on two rollers D and E. A ratchet wheel N is mounted on the shaft of the rear roller E and co-operates with a pawl M oscillated through lever K by a double cam H on the axle of the trailer, backward rotation of roller E being prevented by a second pawl M'. The bellcrank J may be lifted from engagement with the cam H by a handle O operating through links P, R and bellcrank Q. The rate of intermittent movement of belt C may be varied by fixing link K into any one of a series of holes in bellcrank J. Two rotary cross shafts S' and S<SP>2</SP> carry tines T' and T<SP>2</SP> which both rotate in the same direction and are arranged to mesh. A shaft V carries a series of impeller blades W, the shaft V and shafts S<SP>1</SP> and S<SP>2</SP> being driven by chain and sprocket gearing from the vehicle axle. The distributing mechanism is mounted on a frame X which may be detached and replaced by a plain tail unit so that the vehicle may be used as an ordinary trailer. In this form it may be used for tipping, when the endless belt may be operated by hand. The front of the vehicle may be inclined inwards with respect to the vertical and foreshortened so as to permit the belt to pass beneath. A triangular guard is mounted along the walls of the trailer to seal the gap at the sides of the endless belt. A canopy may be fitted to partly enclose the tines and impellers when distributing fine material. A screen of flexible material may be attached to the canopy and extend almost to the ground.

Abstract: 1,180,262. Separation of a component from a fluid mixture by means of a semi-permeable membrane. IONICS Inc. 19 June, 1967 [9 Aug., 1966], No. 28104/67. Headings BIB, B1L and B1X. A component is separated from a fluid mixture by evaporation, dialysis, osmosis or gaseous diffusion, carried out in an apparatus comprising three stacked compartments, the first compartment being separated from the second by an impermeable barrier, and the second compartment being separated from the third compartment by a semi-permeable membrane supported by a porous member in faceto-face contact with the membrane. The evaporator shown has two basic units A, B, each comprising a heating compartment 7 separated by a heat transfer sheet 11 from the compartment 8 through which flows the liquid mixture from which a component is to be separated. The two units have a common vapour compartment 9 separated from compartments 8 by two semi-permeable membranes supported by a member 16 made of porous metal, ceramic or plastic. Spacer members 12 and 13 define tortuous flow-paths for compartments 7 and 8, respectively. Hot water (or other heating medium) is pumped via inlet 22 through compartments 7. Compartment 9 is maintained under reduced pressure by vacuum pumps 26 or, alternatively, a sweep gas may be passed through compartment 9. The feed liquid, e.g. coffee extract or fruit juice, is pumped via inlet 20 through the compartments 8. One of the components of the liquid mixture (water in the case of coffee extract or fruit juice) passes through membranes 10 and is vaporized in compartment 9, the vapours being withdrawn through outlets 21 and 24. The liquid product (concentrated coffee extract or fruit juice) is withdrawn through outlet 23. The membranes 10 and heat-transfer sheets 11 may be made of cellulose nitrate and anodized aluminium, respectively.

Title: Improvements in or relating to frequency modulated ultra-high frequency circuit arrangements
IPC: H03C3/30
Filed: 1952-11-07
Abstract: 721,985. Frequency modulation. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Nov. 7, 1952 [Nov. 13, 1951], No. 28158/52. Class 40 (5). To reduce distortion in a circuit in which the frequency of an oscillator is modulated a correction voltage for adding to the modulating voltage is derived from a phase discriminator, both inputs of which are derived from the oscillator but one being phase shifted by a resonator by an amount proportional to the frequency deviation from the central frequency. In one embodiment, the frequency of a carrier oscillator 1, which may be a reflex klystron, is modulated by the application to one of its electrodes of a signal from source 2. The modulated oscillations are fed through a cavity resonator 3, tuned to the mid-frequency, to a phase discriminator 4 which is also supplied with the modulated oscillations direct. The output from circuit 4 is the demodulated signal, as the phase change in resonator 3 is proportional to the frequency deviation. The demodulated signal is fed to a circuit 5 where it is compared with a reference voltage, from circuit 6, which is proportional to the signal voltage from source 2. The error voltage from circuit 5 is amplified in circuit 7 and fed to the control electrode of oscillator 1 to linearize the modulation characteristic. In a further embodiment, Fig. 2 (not shown), the phase discrimination is effected at an intermediate frequency, produced by beating the carrier with oscillations from a second generator.

Title: Improvements in burglar alarm apparatus
Inventor: SMITH DENNIS WILLIAM
IPC: H04M11/04
Filed: 1958-09-03
Abstract: 881,912. Burglar alarm devices. BURGOT RENTALS Ltd. Sept. 2, 1959 [Sept. 3, 1958], No. 28271/58. Class 40 (4). In a burglar alarm device of the type in which the tripping of an alarm device initiates a call to an exchange and after an appropriate delay sends 999, followed by a recorded message, the sequence preceding the message is controlled by one revolution of a timing wheel driven by the gramophone motor. When the alarm contact AL, Fig. 6, closes relay A energizes the gramophone motor 8 and the transistor amplifier 6 for the pick-up. Relay A also connects up the apparatus to the telephone terminals TR, R, T, and so completes the calling loop over TR, T via contacts 28 which are closed at this time. As shown, Fig. 1, the gramophone motor 14 drives the turn-table 11 which carries a spur wheel 16 driving an impulse wheel 19 coupled by spur wheel 22 to the timing wheel 23. The impulse wheel 19 is arranged to make seven revolutions for one revolution of the timing wheel and is provided with nine indentations 20 for opening impulsing contacts 21. The timing wheel carries a contact 29 which engages a contact strip 5 and is initially adjacent thereto. On its rotation, after the first four rotations, the cammed surface 24 moves the follower 25 to open the switch 28 so as to insert the dial contacts 21 into the loop, so that during each of the next three revolutions of the impulse wheel the digit 9 is transmitted. When the timing wheel reaches the end of its rotation, contact 5 closes to operate B which, besides operating appropriate contacts releases a spring-loaded plunger, Figs. 2 . . . 5 (not shown), to lower the playing arm 12 on to the record, so causing the message to be transmitted. The plunger also latches the relay B in the operated position. Inward radial motion of the pickup causes contact 7 to be made after the transmission of the message, and on the next closure of contact 5 relay C operates, releases A, and connects up a delayed alarm circuit over leads T5, T6. Relay C remains up until the contact 29 is disengaged from spring 5, whereupon it releases and the motor 8 and the transistor amplifier are disconnected. The apparatus is restored by release of the plunger, on manual restoration of the pick-up arm.

Filed: 1958-09-03
Abstract: 864,361. Hydraulic apparatus; accumulators. CRATZMULLER, J. L. Sept. 3, 1958 [Sept. 4, 1957], No. 38289/58. Class 69. (2). [Also in Croup XXXIV] An hydraulic power system suitable for actuating the brakes of a motor car comprises a hydro-pneumatic accumulator 2, Fig. 1, adapted to operate over a wide range of pressure, the minimum of which is at least equal to the pressure to be obtained in a utilization circuit having at least one hydraulic receiver 10, a pump 3 started and stopped by automatic regulating means to load the accumulator with a predetermined amount of pressure liquid, and a pressurereducer 12 interposed between the accumulator and the utilization circuit to maintain the pressure in the circuit substantially constant and independent of the output variations of the accumulator. The accumulator is designed so that it will operate over a wide range of pressure, say 150 kg./cms.<SP>2</SP> to 300 kg./cm.<SP>2</SP>, which allows the system to accommodate changes in temperature from - 30‹ to +90‹ C., and has compressed gas in the left-hand chamber V1 and liquid in the other chamber V0 supplied from the tank 1 and pump 3 which is driven by an electric motor 4 controlled by a pressure-responsive device 6 actuating contacts 7 ; the wide range of pressure is stated to permit the use of a comparatively small volume accumulator and tank. The pressure-reducer 12 is interposed between the accumulator 2 and a distributer 11 controlling the supply to a cylinder 10 in the utilization circuit. In another arrangement, the motor 4 is controlled by a switch 31, Fig. 4, actuated by a cam 16 on the rod 13 of the piston when the volume of liquid in the chamber V0 of the accumulator 2a falls to a predetermined value. If the volume falls to a critical value, an acoustic or visual indicator 42 is operated by the cam actuating a switch 43. The system shown in Fig. 4 may be applied to a motor car braking system in which a circuit 49 leading to the rear brakes is supplied by a distributer 52 from the accumulator 2a, pressure-reducer 12, a non- return valve 47 and an auxiliary accumulator 45, and a circuit 50 leading to the front brakes is similarly supplied. A further circuit 54 for aiding a steering-gear or for controlling a folding hood, windows, or the like, may be supplied through a distributer 41.  The accumulator 2a, Fig. 3, comprises a body portion 27 in screw-threaded engagement with a head portion 28, a lip 29 ensuring tightness between the two parts. The rod 13 of the piston 5 passes through a packing ring 23 pressed against the head by a spring 24 engaging an abutment 26 secured between the body and head parts. The chamber V1 is sealed from the chamber V0 by a packing-ring 30 spring- pressed against the piston 5. Specification 735,660 is referred to.
