Title: Improvements in or relating to trouser presses
IPC: A47G25/72
Filed: 1929-11-12
Abstract: 335,112. Ram, F. R. Nov. 12, 1929. Trouser presses. - A trouser press of the type comprising top and bottom boards e, f which are hinged together at one end and adapted to be pressed together by a lever and stud arrangement a, d near the other end, is provided with a stretching device consisting of a U-shaped frame h which is pivoted to short links g pivoted to the bottom board. The curved ends c of the levers a are arranged to swing the links g, so that the action of closing the press causes the frame to move longitudinally of the press to stretch the trousers. The side arms of the frame are cranked inwardly, so that they underlie the top board e. In a modification, the side arms of the frame are extended, and are pivoted directly to the bottom board near the hinged end of the press. The stretching movement of the frame is obtained by the relative displacement of the frame and press hinges.

The support arm has a slit in a corresponding position to enable adjustment of screw 9 when the hinge is assembled. Fluting 7 prevents undesired longitudinal displacement between the support arm and the upper part 3.

Filed: 1935-12-17
Abstract: 462,407. Vices. STEELE, G. A., and ERRINGTON, W. H. Dec. 17, 1935, No. 34978. [Class 61 (ii)] A pipe-clamping device of the kind comprising an upper clamping jaw 3 and a lower clamping jaw 2 with pipe-engaging teeth has releasable means for locking the jaw and may have auxiliary clamping means 6, 7 for engaging the pipe rearwardly of the jaws 2, 3 to prevent oscillation of the pipe about the clamping point. The jaw 2 and the auxiliary jaw 6 are provided on a base plate 1 to which upstanding bolts 8 are fixed at the four corners. The jaw 3 is pivoted on one of the front bolts and is adapted to be held in pipe-clamping position by a flanged locking plate 5 or swung aside to the dotted position 9. The auxiliary jaw 7 is pivoted on one of the rear bolts and may also be swung aside. Rapid release of the pipe is effected by slacking the sleeve nut 4 and locking plate 5, also the nut at the releasable end of the jaw 7, and then pulling the pipe forward which causes the jaws 3, 7 to swing forward out of engagement with the pipe. The upper jaw 3 is of triangular form with a central dovetail groove providing pipe-engaging points preventing rotation of the pipe in either direction. In the modification shown in Fig. 5, the jaw 3 is formed of metal strip bent to U-form and strengthened by a rivet 3a ; the separate locking plate is dispensed with, the jaw 3 being displaceable transversely of the pipe and the toothed recess of the lower jaw 2 is curved. In another modification, Fig. 7, the sleeve nut engages a curved depression 3b in the end of the jaw 3.

Title: A machine for producing ice plates or slabs and pieces of different shape and size
IPC: F25C1/08
Filed: 1955-12-06
Abstract: 787,876. Ice making. RICHELLI, F. Dec. 6, 1955, No. 35014/55. Class 29 The invention relates to a plate ice machine in which ice is removed from the freezing plates by the combination. of a defrosting cycle with a harvesting device. The machine consists of a thermally insulated tank 2 filled with water to a constant level, the water entering the tank through a false bottom 34 and an opening 37, and containing groups of vertical freezing plates 8 through which refrigerant is circulated from a machine 9. An ice comb 12 sliding on guides 15 surrounds each group of freezing plates 8 and is linked to a pivoted arm 19 by a rod 18. Each arm 19 is connected by a torsion spring 26 to a similar arm 23 linked to a cam 25 on a main shaft 10 by a rod 24. In operation refrigerant is first circulated through the freezing plates 8 by the machine 9 for a relatively long freezing period, during which the shaft 10 is turned and the springs 26 tensioned, the combs 12 remaining at the bottom of the tank because of ice formation on the plates 18. Warm refrigerant is then circulated through the plates 8 for a shorter defrosting period. loosening the ice and allowing the combs 12 under the force of the torsion springs 26 to remove ice from the plates when it floats to the surface of the tank to be harvested by a belt 40. A spring 28 on the rod 24 returns the combs to the bottom of the tank. The cams 25 are angularly staggered on the shaft 10 and refrigerant is supplied to the groups of plates 8 in such a way that there is virtually continuous ice production.

Title: Remote control arrangements for electric apparatus
IPC: H04Q9/14
Filed: 1974-08-08
Abstract: 1476484 Remote control SONY CORP 8 Aug 1974 [16 Aug 1973] 35036/74 Heading G4H [Also in Division H3] A remote control system is designed to transmit and receive control pulse signals of a single frequency but of different pulse widths. As described, the system provides 40 kHz ultrasonic control pulses of 15, 25, 35 and 45 ms. duration separated by 5 ms. intervals for controlling volume increase and decrease, channel selection and power supply for a TV receiver. In the transmitter of Fig. 3 a pair of ganged switches S11, S21 &c. are selected to connect a resistor R1 &c. into an astable multivibrator circuit to determine its period. The multivibrator output controls an oscillator 20-26 connected to an ultrasonic transducer 19. In the reciever of Fig. 4, the ultrasonic pulses are received by a microphone 1, and passed through a band pass filter 2, a detector 3 and an inverter 29 to a gate 4 and an oscillator 6. For the duration of a control pulse, oscillator 6 sends pulses of 10 msec. period to a ring counter 5 whose outputs t 0 -t 6  change sequentially from 1 to 0. The outputs t from the ring counter are fed to counters 31-34; however only that counter corresponding to the last actuated output (e.g. counter 32, output t 3  for 25msec. control pulses) retains its count, the earlier counters (e.g. 31) being reset by NOR gates 41 &c. When five 15 or 25 msec. or seven 35 or 45 msec. control pulses have been received, the respective counter output (111 or 101) cause a NAND gate 51-54 to set the corresponding bi-stable 11-14 whose outputs 15-18 provide the required control signals. Logic circuitry 35-64 is included to ensure that spurious received signals of very short duration have no effect on the system, and that longer unwanted signals cause the system to be reset.

Abstract: 1417225 Internal resistance heating NIKOLAUS SORG GmbH & CO 25 July 1973 [25 July 1972] 35536/73 Heading H5H [Also in Division H2] To prevent the formation of local hot spots between a current supply device 3 and a ceramic electrode 1, a layer 2 of a conductive material which has a melting-point just below the operating temperature of the electrode and is ductile at the operating temperature, is interposed between the device 3 and electrode 1 and is urged into contact with the electrode 1 by device 3. The ductile layer 2 ensures uniform contact resistance across the head of the electrode 1 and the material of the layer is so chosen that it is not squeezed out from the gap between the electrode 1 and device 2. In the glass furnace shown, the device 3 acts as a ram and is secured to a spring-biased ceramic block 5 by a rod 4. The biasing spring 7 acts between the block 5 and the end-plate of a cylinder 6 which is secured to the furnace brickwork supports 10 by an adjusting screw 11. The spring 7 thus biases the electrode 1, which has an annular shoulder, against the furnace lining 9, to take up any movement between the supports 10 and lining 9 during operation. A supply cable 8 is connected to ram 3. The electrode 1 may be made of tin oxide and the layer 2 may be silver solder, e.g. Degussa alloy. The layer 2 may be made of ductile non-metallic materials.
