Filed: 1949-09-02
Abstract: 661,445. Loaf slicers. RATTI, J. Sept. 2, 1949 [Sept. 3, 1948; Aug. 1, 1949], Nos. 22762/49 and 22763/49. Class 28 (ii). An automatic slicing machine for bread &c. comprises a cage 2 having sockets 2a in which are placed vertically loaves 15 which fall to rest on a table 10, the cage 2 being reciprocated horizontally towards and away from a hand-saw 11 situated above the table 10 at a height equalling the thickness of the slices. During cutting, each loaf 15 is held by a spring 24 against the rear wall of the socket, the spring force being temporarily relieved during the return wavecrest of the cage 2 due to the contact of a part 29 (attached through a bar 27 to the spring 24) with a fixed stop 30, thus allowing the loaf to fall and the freshly cut face to contact the table 10 for the next cutting. A flange 2c fixed to the cage 2 pushes each freshly cut slice slightly forward, and this, combined with a step 34 in the table 10, ensures that each slice is free of its loaf after cutting. Each slice pushes the preceding slice towards a conveyer which carries them to an oven.

Title: Improvements relating to electric accumulators
Inventor: BARAK MONTEFIORE
IPC: H01M4/76
Filed: 1949-09-05
Abstract: Tubular retainers for the active material of accumulator electrodes are made from polyvinyl chloride plasticized with polyblend and rendered porous by the process described in Specification 565,022. Polyblend is a mixture of colloidal polyvinyl chloride and the copolymer of butadiene and acrylonitrile, the mixture being fused by heat to produce a rubber-like plastic material which may contain from 55 per cent to 80 per cent of polyvinyl chloride.  The final mixture from which the tubes are made may contain from 99 to 77.5 per cent of polyvinyl chloride and from 1 to 22.5 per cent of the nitrile rubber. The tubes are made by mixing the polyvinyl chloride and polyblend with maize starch and methyl cyclohexanone and heating the mixture to 100 DEG  C. and then extruding it into tubular form and cutting it into the required lengths.  The tubes are immersed in boiling water and then placed over glass mandrels and finally immersed in sulphuric acid which removes the starch and causes the tubes to shrink.  They are then washed and treated with a wetting-out agent and dried.

Title: Improvements in or relating to hydraulic pumps
IPC: F16H61/42
Filed: 1920-08-07
Abstract: 172,369. Variable Speed Gear, Ltd., and Ingoldby, M. K. Aug. 7, 1920. Hydraulic transmission of power.-In a variable-stroke pump of the kind having a tiltable or other movable stroke-controlling member operated by a hand-lever &c., and having also an automatic control device depending on the pressure in the system for preventing undue adjustment of the stroke-member and for automatically reducing the stroke when the pressure rises above a certain point, means are provided whereby the control lever A is prevented from receiving a movement which is additional to its normal stroke-controlling movement, unless the strokecontrolling member A<1> is in a position corresponding to that at which it is desired to give the additional movement. In the form shown, the additional movement of the lever A is transverse to its stroke-controlling movement about the pivot a for the purpose of clutching together the driving shaft of a pump and the driven shaft of a motor when the member A<1> is in full stroke position, as described in Specification 150,794. The means controlling this additional movement consists of a stop lever c which is connected to the stroke adjusting mechanism of the member A<1>, so that the end of the lever blocks the transverse movement unless the member A<1> is in full stroke position. The automatic control consists of a fixed piston B<1> in a movable cylinder B<2> connected at opposite ends through the piston rods b to the pressure and suction sides respectively of the pump. The cylinder carries two stops b<2> limiting the movement of the hand-operated stroke-adjusting lever a<1x> and adapted, when the pressure exceeds a certain limit, to restore the member A' to no-stroke position. A spring link A<2> is provided in the hand-control linkwork to permit this automatic adjustment without affecting the position of the lever A. A balancing device D and a dashpot D<1> are provided for the purpose described in Specification 172,070.

Title: Pulse code modulation transmitter
IPC: H04B14/04
Filed: 1971-04-19
Abstract: 1348277 Transmitters for pulse code modulation systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 April 1971 [12 March 1970] 23498/71 Heading G4H A transmitter for a P.C.M. system comprises a first analogue to digital converter 9, an attenuator 12, a second analogue to digital converter 13, a network 14 having a non-linear characteristic, error correcting devices 24, 25 connected to each respective analogue to digital converter and a circuit 23 which controls each error correcting device according to the value of the bit stored in the most significant stage 22 of the first analogue to digital converter. The input analogue speech signal is fed through a microphone 1, a sampling device 4 controlled by a pulse generator 6 and a delay circuit 8 to the attentuator 12. The analogue signal is also fed through the network 14 and a threshold device 15 to the analogue to digital converter 13 which is connected to a digital to analogue converter 28. The network 14 forms the logarithm to the base two of the analogue signal and three units are subtracted by the device 15, the resulting number being binary encoded and fed to a shift register 19. The binary coded attenuation factor is converted to an analogue signal by the converter 28 and sets the attenuation of the attentuator 12. The analogue signal, divided by the attentuation factor, is converted to a digital signal by the converter 9 and fed to a shift register 18 via the device 24 which consists of four electronic two position switches. Circuits 10, 11 supply a polarity bit which is transmitted via an 'OR' gate 20 in sequence with the binary coded attenuation factor and amplitude value. In the event of the circuit producing a too low attenuation factor the high analogue amplitude signal fed to the converter 9 causes a "1" bit to be present in the stage 22. The circuit 23 therefore changes over the state of the electronic two position switches thereby connecting the second to fifth stages of the converter 9 to the register 18 instead of the first to fourth stages. Thus the correct binary coded amplitude signal is fed to the register 18 and the attenuation factor is corrected due to the circuit 23 closing a switch 26 to add a voltage signal to the output of the circuit 15. A modified transmitter is described for correcting too high attenuation factors and a transmitter in which the analogue to digital converters each comprise a pulse duration modulator connected to a counter is also described, this latter transmitter enabling correction of both high and low attenuation factors.
