Title: Improvements in and relating to methods of and apparatus for sorting balls according to size
IPC: B07C5/06
Filed: 1935-05-03
Abstract: 457,920. Separating solid materials. SPENCER MOULTON & CO., Ltd., G., 2, Central Buildings, Westminster, and CHRYSTAL, J. M., Kingtson Mill, Bradford-on-Avon. May 3, 1935, No. 29622/36. Divided out of 457,881. [Class 117] Relates to apparatus for sorting balls of the kind comprising a runway provided with apertures of progressively increasing size, and consists in feeding the individual balls successively to the runway and clearing the apertures and advancing the larger balls along the runway in synchronism with the feed. The invention is described in connection with a duplicate machine having two runways, and feeding shoots and two sets of clearing devices working in alternation. The clearing devices consist of platens 60, 61, Fig. 3, resiliently carried by a rock-shaft 32 extending the length of the grading runway. The feeding devices consist of traps 5, 6 unidirectionally connected to shafts 41, 42 at the lower end of shoots 3, 4. The traps are lifted positively by the shafts to release a ball, and fall by their own weight. The shafts are connected by links 45, 46 to the shaft 32 so as to synchronize with the clearing devices. The drive of the shaft 32, the device for supplying the balls to the shoots 3, 4, and the construction of the shoots are the same as in Specification 457,881. Specification 457,919, [Group XXX], also is referred to.

Abstract: 606,693. Impedance networks. SELGAS Y MARIN, E. DE. Nov. 7, 1945, No. 29661. Convention date, Jan. 20. [Class 40 (viii)] [Also in Group XXXVII] An adjustable impedance network such as an equalizer, filter, variable capacity or means for producing a variable time-constant comprises sections or arms 9 connected by pairs of contacts 1 which are successively opened as re-' quired by a sliding member having a conductive surface 4 and an insulating surface 3, so that only those sections or arms 9 which are to the left of the bar are in circuit. Twoterminal arms, such as condensers may each be connected between two contacts instead of the three shown. In a balanced line, Fig. 2 (not shown), there are two bars 3, 4, and each section 9 has four terminals each of which is connected to a different contact 1. The contacts may be arranged in a circle or spiral.

Filed: 1925-11-24
Abstract: 265,717. Leitner, H., and Watts, H. C. Nov. 24, 1925. Screw propellers.-In airscrews of the kind in which the blade, is pivotally secured to the hub and is adjustable for pitch, each blade comprises a bar of high tensile steel or light aluminium alloy enclosed in thin sheet material constituting the front and rear surfaces of the blade. Each blade b, Fig. 2, consists of a tapering bar a with sheet metal surfaces as b<1>, the root of the bar is flanged at q, s, and is adjustably clamped by a divided coupling u to flanges r, t on a member o which has a knuckle type hinge connection at n with a bracket on the hub m. The hinge axis may be set at any angle to the shaft axis. Spring stops w control the pivoting motion and stops x coacting with the strap u limit the motion on failure of the springs. Two opposed blades may be hinged on a common axis. The bar a may be divided at its outer ends k, Fig. 17, and may terminate at any position short of the blade tip. The pivoted connection may be made between the bar and a cylindrical portion adapted to be adjustable for pitch in a boss socket. The outer skin may be in one sheet, Fig. 6, or two sheets united at the connection with the bar, Fig. 5.

Title: Integrated circuit array of cells
IPC: H01L21/82
Filed: 1968-06-21
Abstract: 1,209,268. Integrated circuit arrays. R.C.A. CORPORATION. 21 June, 1968 [23 June, 1967], No. 29723/68. Heading H1K. [Also in Division H3] In an array of cells supported by a common substrate and arranged in a number of rows with intervening runways, a supply line supported on a layer of insulation extends back and forth in zig-zag fashion along at least some of the runways. In the described arrangement a general plan view of which is shown in Fig. 6 each cell consists of four IGFETs the channels of which are defined by P-type source and drain regions diffused into the silicon substrate. The wide-length ratio of the channels is so selected that two of the IGFETs 20, 21 (Fig. 7) have relatively high transconductances g m , another, 22, has a low g m  and the fourth, 23, an intermediate value of g m . Along alternate runways extend lines carrying supply voltages and clock pulses as shown. Each runway is crossed by certain of the diffused regions 28, 46, 47, which are common to adjacent cells in a column and which contact certain of the conductors through etched holes 43, 44, 45 in the oxide insulation. Diffused regions 48 disposed between the cells provide further paths for intercell connections, while other connections within and to the cells are formed by depositing metal on the oxide insulation and via zones common to two devices. In some arrangements certain of these common zones have to be replaced by metallic interconnections as their leakage resistance would increase the circuit time constants to an unacceptable level. The internal cell connections and connections between cells may be varied to provide inverter circuits, two-input logic gates and delay stages of a dynamic register.

A flat annular air-gap A.C. induction motor comprises a printed-circuit two-face stator winding member 5 mounted between two rotor members, one of which has a squirrel-cage winding 10 supported by a magnetic core 11 and the other of which includes a magnetic structure 13. In the embodiment shown, the two rotor members are screwed together by a ring 14 and are keyed to a shaft 16 borne in a sleeve 15 in a central hub 2 to which the stator 5 is secured by a ring 6, but in other embodiments the stator periphery is secured to a base plate flange 4 by a threaded ring and the two rotors are either joined together at their centre, or are relatively rotatable. The second rotor 13 may be either a yoke plate of spiralled magnetic tape, or a ring of magnets or magnetized coercive ferrite; if it is a yoke plate, the motor operates asynchronously, but if it is magnetized the motor is stated to operate synchronously or self-synchronously depending upon whether the two rotors are relatively fixed or rotatable.
