Title: Improved manufacture of plates from resins or the like
IPC: B29C33/00
Filed: 1928-09-27
Abstract: 303,103. Herold Akt.-Ges. Dec. 28, 1927, [Convention date]. Moulding artificial resins.-Thin plates of artificial resin are obtained by introducing a number of metal sheets, preferably nickel, spaced apart the thickness of the plates desired, into a mass of artificial resin in the liquid phase and subsequently heating to the hardening temperature. The metal sheets may be of zig-zag or other section to produce plates which can be readily cut into rods &c., and may be parallel or inclined to one another. By withdrawing the plates after gelatinization, the spaces may be filled with a liquid of a different colour to obtain patterned products. Small articles e.g. umbrella handles are given a clouded or mottled appearance by filling a mould about one-third with clouded liquid material and pressing in a solid block to displace the material.

Title: Periodic wave generator particularly for use in television
IPC: H03K4/43
Filed: 1939-10-12
Abstract: 535,661. Valve generating circuits. HAZELTINE CORPORATION. Oct. 12, 1939, No. 27764. Convention date, Nov. 4, 1938. [Class 40 (v)] In order to improve the wave form of the deflecting current or voltage in cathode ray tubes, the effect of undesired capacitance (or inductance) in inductive (or capacitative) deflecting circuits is compensated by providing inductance and capacitance in the input circuit of the output valve, or in the input and output circuits of an additional valve between the oscillator and the output valve. In Fig. 1, the condenser 15 represents the inherent capacity of the inductive load 14 (e.g. the deflecting coils) and the valve, and the resistance 16 represents the inherent shunt conductance of the output circuit and the valve. The effect of 15, in parallel with 14, is compensated by the inclusion in the input circuit of the valve of an inductance 12 in series with the condenser 11, which integrates the current pulses supplied by 17 to develop a saw-tooth current in the output circuit. In order to secure maximum saw-tooth current through the inductor 14 without exceeding the normal current and voltage swings of the valve, the wave-form of the input pulses is such that the load diagram of the output current and voltage has at least one cross-over during each cycle of the current, preferably during the retrace interval of each cycle. In a modification, Fig. 2 (not shown) in which the inherent series resistance of the inductive load is taken into account, the compensating elements are divided between the input and output circuits of an additional valve. In a further modification, Fig. 3 (not shown), the compensating circuits are modified to allow the use of a step-down transformer between the output valve and the inductive load, so as to permit the use of a low-impedance secondary circuit. Similar arrangements are described, Figs. 4 and 5 (not shown) for compensating for the inherent shunt conductance and inductance in an output circuit feeding electrostatic deflecting plates.

Abstract: 707,390. Kinematograph apparatus. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Nov. 5, 1951 [Nov. 22, 1950], No. 28528/50. Class 97(1) [Also in Groups VII and XL(b)] In a step - by - step linear drive mechanism for kinematograph film apparatus, the application of a reciprocating driving force at a single point on a drive member causes one end of said drive member to move over a rectangular path due to the provision of mechanical restraining means which enable the end of the drive member to move in the direction of its length and breadth during both the forward and return strokes of said reciprocating force. When the reciprocating force indicated by the arrows at 4 is applied to the drive member 3 the engagement of surface 13 with a surface 11 on pawl 5 forces the member 3 to move horizontally until surface 19 engages a surface 20 on a guide member 27 and the remainder of the forward stroke moves the member 3 upwardly until a projection 21 engages the under surface of a fixed abutment 17. Also a spring-biased pawl 8 is rocked clockwise against a spring 10 and the member 3 in its uppermost position engages a surface 23 so that downward movement is prevented. On the application of the return stroke the head of the member 3 is moved to the left until the surfaces 22, 23 disengage, the latch 5 is rocked to its normal position, and in the final position of the stroke the member 3 moves downwardly until its surface 13 latches with the projection 11 on the pawl 5. The member 3 carries pins 26 for engaging feed perforations in the film and a member 27 moved oppositely relative to the member 3 carries pins 34 engaging the film when the pins 26 are engaged, and vice versa. In a modification, Fig. 5, a ball 40 carried by a frame 41 engages an upper recess 43 in the member 3 which, after lateral movement bringing surfaces 19, 20 into engagement, moves upwardly until the ball 40 snaps into the recess 44 and a surface 47 engages a fixed surface 48. On the reverse stroke of the reciprocating force the member 3 slides to the left and during the final part of the stroke, the member 3 moves downwardly so that the ball 40 snaps into the upper recess 43.
