Title: Improvements relating to slicing machines
IPC: B26D7/01
Filed: 1945-01-25
Abstract: 594,417. Slicing-machines. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd., and THOMAS, H. Jan. 25, 1945, No. 2058. [Class 28 (ii)] The slice thickness gauge plate 3 of a slicer is adjusted by a hand-turned knob 8 through a bell-crank lever 19, 20 designed so that equal turning movement of the knob produces slice thickness adjustment of progressively increasing size whereby the thinner slices have finer adjustment for the same amount of turning of the knob. A helical cam 15 on the knob shaft 9 engages a roller 22 on the crank arm 19 to rock the arm 20 whereby its roller 23 moves a plate 16 fixed on a guide shaft 12 secured to the gauge plate 3. The guide shaft 12 thereby slides axially in its bearings 14B. The gauge plate movement is steadied by another shaft 13 also attached to the gauge plate 3 slidably in a bearing 14A. This shaft 13 is short so that at extreme opening of the gauge plate it becomes free of its bearing so allowing the gauge plate to be rocked on a shaft 12 away clear of the disc knife when desired. The inclination of the gauge plate supports is designed that the greater the slice thickness the greater the clearance between the gauge plate and the back of the knife for passage of the slices. The faces of the plate 16 which contact with the roller 23 may be cam shaped to vary the result of the setting of the gauge plate.

Title: Improvements in or relating to telecommunication systems
IPC: H04M15/38
Filed: 1938-01-25
Abstract: 510,012. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., and WRIGHT, E. P. G. Jan. 25, 1938, No. 2408. [Class 40 (iv)] In a system in which information used for computing charges for calls is recorded by printing or like equipment, apparatus associated with the connection stores the calling and called numbers and the duration of the call and the printing equipment comes into use at the termination of the call and receives the records from the storage apparatus. The storage apparatus (Fig. 1) which is individual to a toll junction comprises a pair of registers R1, R2 which control code relays A-F in the printing equipment (Fig. 2) when the latter is associated with the storage apparatus over a finder F. The digits of the called number are recorded in turn on R1, to which impulses are repeated at contact ta, and the settings are transferred to R2 as positive or negative charges on condensers connected to successive positions of wipers rm24-28. The relapse of CC at the end of each train restores R1 and advances R2 one step. The digits of the calling number are received in a similar manner from identifying equipment to which a starting signal is sent by means not shown, and these are stored in subsequent positions of R2. On the reply of the called party, relay M energizes at contact tm and R2 restores, whereupon CC pulls up and places R2 under the control of time pulses on wire 3SGL. When R2 reaches position 20, after one minute of conversation, C pulls up and disconnects CC to advance R1 one step, and R2 goes quickly to normal and starts a fresh cycle. Upon release, the relapse of B connects up C, S, R1 takes a step to record the uncompleted minute of conversation and R2 restores. The finder F now picks up the storage apparatus and T energizing in the test circuit connects up W, which connects wipers rm24-28 to relays A-F. One of relays A-E is operated by the charged condenser and F operates if the charge is of a particular polarity. The operated relay or relays lock in series with G and send a code signal to the printer, the printing magnet of which opens the locking circuit at contact TMC. The relapse of G advances R2 one step. The duration of the conversation in minutes, tens and units digits, is transferred in positions 18, 19 of R2 which are cross-connected to the banks of wipers rm14, 15, the former being connected to positive battery (since the tens digit cannot exceed 5) and the latter to positive or negative battery over wiper rm12. Relay W falls back in position 19 and disconnects M to free the apparatus. In blank positions 10, 17 of R2 interposed between the three records, relay G alone energizes and operates the tape-stepping magnet which releases G at contact SMC. The calling number may be recorded at the end of the conversation instead of before reply, or it may be recorded during conversation if separate means are employed for recording the duration. Specifications 440,348, 484,568 and 507,431, [Group XXXVII], are referred to.

Title: Improvements in or relating to Receiving Apparatus for Wireless Telegraphy.
Inventor: BRILLOUIN LEON NICOLAS
IPC: H03D1/16
Filed: 1917-02-22
Abstract: 127,013. Brillouin, L. N., and Beauvais, G. A. March 27, 1916, [Convention date.]. Telephonic relays.-In receiving-apparatus for wireless telegraphy, one or more vacuum tubes are arranged to act both as amplifiers and rectilying detectors, the grid of each tube being connected through a resistance to a point which is at a positive potential relatively to the positive end of the filament. Fig. 3 shows an arrangement with three tubes, with their filaments f<1>, f<2>, f<3> connected in parallel across a battery A. A potentiometer P is connected on the one hand to the positive side of the battery A and on the other hand through resistances r<1>, r<2>, r<3> to the respective grids g<1>, g<2>, g<3>, in order to raise their normal potential above that of the filaments. The plates p<1>, p<2>, p<3> are connected, preferably through resistances R', R<2>, R<3>, to one side of a highvoltage battery V, the other side of which is coupled to the positive end of the filaments. Each plate is also connected through a condenser c<2>, c<3> to the grid of the next tube, the last plate being connected to a telephone receiver T. The incoming oscillations pass through the terminals B and act through a condenser c<1> to vary the potential of the grid g'. An amplified and partially rectified oscillation thus produced in the plate-filament circuit of the first tube, varies the potential of the second grid and so on, the rectified current being detected by an ammeter, or by a telephone receiver if the waves are of audible group-frequency. The plate of one tube may be connected through condensers to the grid of a preceding tube to increase the amplification. The capacities c<1>, c<2>, c<3> are small, in order to transmit readily only currents of high frequency. The apparatus is stated to reduce strong interfering waves, and to amplify only weak signals; and noises due to irregular working of the tubes are suppressed.
