Abstract: 504,080. Ice-making. GENERAL MOTORS CORPORATION. May 6, 1938, No. 13557. Convention date, May 10, 1937. [Class 29] [Alao in Group XXII] A removable metal grid of a domestic ice-making tray comprises a longitudinal wall formed of several sections 13, 14, loosely connected together by transverse plates 30 in such a manner as to permit limited distortion of the grid as a whole in any direction to facilitate release of the ice cubes therefrom. The longitudinal sections are formed of folded metal sheets, one end section 14 and the intermediate sections being forked to embrace the edge of an adjacent section. Vertical slots formed in the forked edge of one section and the plain edge of its co-operating section are aligned, as shown in Fig. 4, and one transverse plate 30 with a bent over lip 32 is threaded through these slots. The other transverse plate has initially a tongue 32<1> which is threaded through the same slots and this tongue is then bent over to provide a similar lip 32 which locks all the plates together. Clearances 40, 41 between the plates permit the distortion. When the grid is placed in a tray with sloping walls the grid takes up the form shown in Fig. 1 with the transverse walls vertical and parallel. One end plate 14 may be formed with a notched lug 50 to receive a tool for prising the tray away from the grid when frozen.

Abstract: 1,217,032. Loom dobby. STAUBLI & CO. GEB. 21 March, 1968 [25 April, 1967], No. 13826/68. Heading D1E. A needle 5 which reads a pattern card 13 is moved with greater force further into the cylinder 12 if it feels a perforation such movement controlling the heald. Each needle 5, 5' is moved by a holder 21, 21' having a projection 27, 27' engagable by a pivoted driving lever 26, 26'. When the lever 26' swings anticlockwise from the initial position, the holder is urged towards the card by spring 28'. If the needle is resisted by the card arm 26b' of the lever passes the projection, while if a hole is felt the arm drives the holder and needle e.g. 5 positively into the cylinder. Such positive movement raises the baulk lever 1 from stop 11. If arm 26b' does engage the projection when the needle is resisted, relative movement between needde and holder is permitted by spring 15. In a modification (Fig. 2 not shown) a draw lever (30) is dropped into the path of a knife (14) when a supporting lever (32) is swung aside by a projection (31) on the holder. In a further embodiment, figure 7 the holder is moved by a reciprocating bar 56 which engages arm 57 which is carried outwards by stop 54a as the needle feels a hole. In a further embodiment (figs. 8, 9 not shown) the end of the holder adjacent the reciprocating bar is laterally offset from the remainder and has a cut-out (67) which engages the arm when the off-set part passes fixed guides and is thereby swung towards the bar as it feels a hole.

Title: Improvements relating to ramp form voltage generators

Filed: 1965-04-02
Abstract: 1,136,407. Limiting rate of change of voltage; ramp generators. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 1 April, 1966 [2 April, 1965], No. 14182/65. Headings H3P and H3W. [Also in Division G3] In a system, particularly for controlling the speed of a lift, in which a step voltage control function is converted into a ramp function, the step voltage is fed to an integrator A2 via a current limiting circuit D, the limiting value of the current limiting circuit being gradually increased from zero on occurrence of a step control voltage so as to limit the first and second differentials of the output ramp function. As shown, the acceleration and deceleration of a lift are respectively controlled by energizing and releasing a relay SR (coil not shown). On energizing relay SR, contacts SR/1 feed a voltage step via amplifier A1 to a Miller integrator A2. Contacts SR/3 switch a previously discharged capacitor C1 across part of a potential divider R11, P4, R14, R12 so that as capacitor C1 charges it gradually increases the current limiting value of a diode bridge D so as to limit the rate of change of current fed into the integrator A2 and hence the second differential of the output ramp function at V2. When capacitor C1 becomes fully charged, the input current to the integrator A2 remains constant at a value determined by capacitor C1 until the output voltage V2, which is fed back via resistor R2, reaches a value such that the input to amplifier A1 is nulled. The output then remains constant until relay SR is released when its contacts reverse their positions, discharging C1 and allowing the previously discharged capacitor C2 to provide a similar function so that the output voltage decreases to zero, decelerating the lift. The linearity of the control current from capacitors C1, C2 may be improved by a further diode bridge in series with bridge D.
