Abstract: 505,764. Television receivers. WHITE, E. L. C. Oct. 15, 1937, No. 28110. [Class 40 (iii)] Line and frame synchronizing signals, distinguished by duration, are isolated by a valve 1 and applied to an inductance 11, the current. in which grows to a value dependent upon the duration of a signal. At the end of the signal, the inductance 11 and shunt capacity 7 oscillate to give a pulse at 13 whose amplitude depends on the duration of the synchronizing signal. The larger amplitude pulses correspond to frame synchronizing signals and are isolated by an amplitude filter or the whole train may be applied to a frame deflecting oscillator biassed to respond to the larger pulses only. The oscillator may be of the type described in Specification 402,629. The line deflecting oscillator may be controlled by pulses from 12, or 14. The condenser 7 may be the distributed capacity of the inductance. The inductance is preferably damped by a resistance 10. Specification 455,375 is referred to. Reference has been directed by the Comptroller to Specification 484,412.

Abstract: 980,328. Electrically released switches; protective arrangements. ELEKTOPRISTROJ, NARODNI PODNIK. Aug. 3, 1961 [Aug. 6, 1960], No. 28173/61. Headings H2B and H2K. A polyphase protective device comprises two bimetallic members 1, 2 for each phase, the members acting in opposite directions and having their free ends co-operating with a lever 6 pivoted on a member 9 which is pivoted on the frame of the device at 11 and normally maintains contacts 12 closed. The bimetallic members may be directly or indirectly heated by the phase currents and the members 1, 2 have different time constants. Under normal load conditions, the members 1, 2 for each phase bend towards each other and the lever 6 pivots without substantial lifting of the lever 6. On a symmetrical overload the lever 6 is lifted sufficiently to turn the member 9 about the pivots 11 and release the contacts 12 which open. In the event of unbalance due to failure of a phase, the lever 6 is lifted due to the cooling of the member 2 associated with the defective phase and the heating of the members 1 associated with the other phases, Fig. 4. The members 1, 2 for each phase may be formed by a single strip bent into a U-shape, Fig. 2 (not shown) A stop for the lever 6 may accelerate tripping under balanced overload conditions, Fig. 5 (not shown).

Abstract: 726,777. Shaping prior to tanning or finishing leather. SECOTAN, Inc. Dec. 4, 1951, No. 28364/51. Drawings to Specification. Class 76. [Also in Groups VII and XVI] A process of forming hollow leather articles such as shoe uppers directly from limed, dehaired and bated or pickled and untanned skins comprises clamping the margins of the blank and forcing the unconfined area of the blank by fluid pressure into conformity with a hollow porous mould. The pressure may be by suction or direct liquid pressure, in which case the liquid may be a dehydrating fluid such as acetone or alcohol. This may be followed by other treating liquids such as the tanning liquids, fat liquor and a dyeing liquid in any order. The surface of the mould may be such that it produces ornamentations or other markings on the grain side of the skin, and in shaping an upper a marginal flange or a bellows formation at the instep may be produced. The blank may be tensioned in any direction to cause the fibres to be oriented in any desired direction. A treated shoe upper may have a stiffening compound applied directly to the counter or toe portions while in the mould. For producing lined uppers, superposed plies of untanned skin may be employed and treated as a single blank. The apparatus used comprising the porous mould is described and claimed in Specification 726,828. Any watermiscible solvent may be used in place of acetone or alcohol. A chrome tanning solution or vegetable solution may be used or aldehyde, aluminium, titanium and zirconium tanning solutions. It is practical to combine the tanning and dehydrating solutions.

Filed: 1970-06-11
Abstract: 1318431 Seaming non-metallic sheet material EASTMAN KODAK CO 11 June 1970 [16 June 1969] 28367/70 Heading B5K [Also in Division G2] An apparatus for ultrasonically splicing webs such as thermoplastic film comprises a stage S on which are supported the film strips F1, F2 which are to be joined in end to end relationship, and an ultrasonic horn 27 whose lower end bridges and overlaps the film ends to be joined. Splicing tape. is fed forward between the horn and the stage, and the end is cut off to form a splicing patch. The film strips F1, F2 are placed in channels in the stage S, and held there by vacuum means actuated by switches 23, 25. The facing ends of the strips extend into a central recess 21 where they are trimmed by cutters 13, 15. A retractable carriage C can be moved forward towards the horn by a pneumatic piston, and draws the forward end of a roll of splicing tape under and then up into contact with the under surface of the horn. A knife blade cuts off the end 29 of the tape and leaves a rectangular splicing patch adhering to the horn by vacuum means. The tape actuating mechanism can be a separate unit removably bolted to the support frame A of the device. The remainder of the operation is controlled automatically by the circuit of Fig. 11 (not shown), and initiated by closing the two switches PB1 and PB2. The stage S is raised so as to bring the film ends into contact with the splicing patch adhering to the horn. In this position the stage is still about À002 inch away from touching a pair of micrometers M. The horn is now energized for a predetermined time, which softens the splice materials and allows the upwardly urged stage to compress them slightly. The amount of such compression can be controlled by the micrometers. After the horn is de-energized, all holding means are released and everything returns to its initial position, when the spliced film can be removed.

Title: Improvements in temperature control apparatus
IPC: G05D23/19
Filed: 1954-10-05
Abstract: 772,504. Automatic temperature control systems. MINNEAPOLIS - HONEYWELL REGULATOR CO. Oct. 5, 1954 [Oct. 5, 1953], No. 28669/54. Class 38 (4). In a temperature-controlled heating system a relay controls the circulation of the heating medium and is itself partially controlled by a thermal switch at a reference location which deenergizes the relay when the temperature at that point exceeds a predetermined value. In the embodiment described, water heated in the boiler 10 by burner 25 under the control of unit 30 circulates through the mains 13, 22 when pump 23 and valve 24 are operated by the source 121 through the amplifier and relay 32. This is energized by the unbalanced output of bridge network 31 which depends on the relative values of the temperature dependent variable resistor 34 in the return main and of a resistive element 110 of a thermal switch 33 at a reference location so that when the temperature at the thermal switch, and consequently the value of resistor 110, falls, the pump 23 is energized and the bridge re-balanced when the temperature and resistance of element 34 have risen by a predetermined amount, when the relay is deenergized and the pumping stopped. The thermal switch 33 having a contact 105 and controller 106 and connected in parallel with switch 61 is such that when 61 is open, during the night period in this case, it controls the relay 32 and when the temperature experienced by resistor 110 exceeds a predetermined value contact 105 is opened and the pump 23 cannot be energized. Cams 41 and 42 rotate once every 24 hours by the motor 43 operate switches 52, 53, 61, 62 to introduce additional resistors into the bridge circuit to maintain a lower temperature of the water by night than by day by varying the relationship for bridge balance between 110 and 34. Thus, at night, the cam followers 51 and 60 ride on the lower portions 44, 54 of the cams to switch out resistor 90 and insert resistor 94 and potentiometer 92. Further, the cam lift 50, which is ahead in time of that on cam 42 and corresponds to the early morning period, temporarily provides an excess heating period to raise the temperature rapidly from night to day value. The various relationships produced between resistive elements 110 and 34 are adjustable by potentiometers 91, 93, 100 and 103.

The input shaft 91 is connected to the shaft 60 by a pawl 95 urged into engagement with ratchet teeth formed in a wheel 94 integral with the latter shaft, by a spring 97. The pawl 95 is provided with a projection 95b which, after a predetermined rotation of the shaft 60, abuts a cam 98a, Fig. 17, formed in a cap 99 and thereby disengages the pawl and allows the shaft 60 to return under the torsional resilience of the tube 50. The shaft 92 remains stationary due to the one-way drive of a ratchet 93, and the shaft 91 continues to rotate until the projection 95b rides off the cam surface 98a and allows the pawl 95 to engage another ratchet tooth. The tube 50 may be of metal, rubber of plastics material.
