Title: Selector for edge notch coded sheet-type items
IPC: G06K21/00
Filed: 1970-11-24
Abstract: 1298378 Selecting cards IMAGE SYSTEMS Inc 24 Nov 1970 [5 Dec 1969] 55770/70 Heading G4M Edge-notched cards 75, Fig. 2, are selected by complementary pairs of selector plates 17, 18, each pair of plates 17, 18 has an associated pinion 25 meshing with racks formed on the plates and spring-biased plungers engage the plates 18 to urge them towards the advanced position shown in Fig. 2 while simultaneously urging plates 17 towards the retracted position by means of the rack and pinion coupling. Solenoids 36, when energized, retract the associated plates 18 and thus advance the corresponding plates 17. The plates 17, 18 are retained in the selected positions by a spring-biased locking bar 49, Fig. 1, which engages hooks 46, 47 at the forward edge of plates 17, 18 and which is releasable by a solenoid 54. The front edges of plates 17, 18 are curved to conform with the periphery of a rotatable drum 41 in which the cards are stored. As the cards 75 rotate past the selector plates 17, 18, magnetic elements 76 are attracted by a magnet 65 which rotates as the cards pass by, and a card bearing the selected combination of notches partially moves out of the drum 41 to actuate a switch 79, for slowing down or stopping rotation of the drum, before its T-shaped notch 78, Fig. 2, is engaged on a retainer bar 82. On further rotation of drum 41, the selected card leaves retainer bar 82 so that its notch 78 may be subsequently engaged by an extractor mechanism. The magnetic elements 76 on the cards may be U-shaped clips.

Abstract: 1466807 Logarithmic amplifiers STANFORD RESEARCH INSTITUTE 31 Dec 1974 [22 July 1974] 56129/74 Heading G4G A logarithmic amplifier circuit, which may be used in a system in which acoustic transducers provide amplitude modulated signals which are to be processed, comprises a variable gain linear amplifier the gain of which in dB is proportional to a control signal and an envelope detector receiving the output of the amplifier to obtain a signal proportional to the level of an amplitude modulated signal at the circuit input, the detector output signal being applied as the gain control signal of the amplifier. In Fig. 1, the amplifier 10 includes two series connected amplifiers 20, 22, the latter being of constant gain and the former being gain-controlled at pin 5. The detector circuit 32 includes two common collector transistors 50 the gain control signal being taken from the collectors via a transistor switch 108 for combination with constant gain control signals set by potentiometers 28, 98, the combined signal being fed via an isolating circuit 26 to pin 5 of amplifier 20. The output is taken from the emitters of transistors 50 via a gating circuit 62 to a store capacitor 60 and thence to any desired utilization circuit. In the particular application described the circuit is operated sequentially by gating signals, but these are not material to the basic operation.

Abstract: 1,162,848. Electric selective signalling. GOTAVERKEN A.B. 21 Dec., 1966 [30 Dec., 1965], No. 57209/66. Heading G4H. A ship's engine plant may be controlled from either of two control posts, the bridge and engine room, each control post including a receiver, transmitter and telegraph unit, the telegraph unit 11 (Fig. 1) in the engine room, having, in addition to order indicating positions an extra position B to which the handle 10 of the telegraph unit 11 is moved when the bridge takes control. To take control on the bridge.-Closure of a switch 1 operates an alarm device 7 and a lamp 8 in the engine room to indicate that the control is to be transferred to the bridge. If a switch 9 in the engine room is then operated relays 13, 14, 15 are energized to switch off a lamp 17 and light a lamp 20 on the bridge and to switch off a lamp 19 and light a lamp 21 in the engine room. When the handle 10 of a telegraph unit 11 is manually moved to position B the alarm 7 and light 8 are cut off and a double pole switch 23 is closed to energize a relay 23 so that the order indicating part of the engine telegraph unit is disconnected and control is transferred to the bridge. To transfer control from the bridge to the engine room.-Switch 26 on the bridge is closed to de-energize a relay 3 and turn on a control lamp 27 in the engine room. The handle 10 is then moved to position B so that the telegraph unit is enabled to show orders transmitted from the bridge. A lamp 20 is switched off and a lamp 17 switched on when a switch 28 is pressed to indicate that control has been transferred. Orders from the bridge indicated by lighting up of a corresponding position on the engine room telegraph unit are then effected by moving a control handle 29. To transfer control to the engine room at the request of the engine room.-Handle 10 is moved from position B to a position corresponding to " slow " to open switch 22 and de-energize relay 23. This results in the " slow " light being illuminated at the bridge and an alarm sounded. Operating switch 26 and moving the bridge handle 32 to its " slow " position then transfers control to the engine room.

Abstract: 1,201,920. Boring earth &c. CEMENTATION CO. Ltd. 12 Dec., 1967 [28 Dec., 1966], No. 58021/66. Heading E1F. An adjustable platform assembly supporting earth boring equipment comprises a platform which is raised and lowered to move a boring tool into and out of the ground at a desired inclination, the platform having hydraulically actuated legs 25..28, Fig. 3, at or near four corners with the hydraulic fluid lines to two adjacent legs 27, 28 being interconnected to effect common controlled movement of said legs while movement of the two other legs is independently controllable. Supply and release of fluid to the legs is controlled by electromagnetically-actuated valves 20..23 and movement of the valves is controlled by three electric switches 31..33, Fig. 5, actuable by a pendulum 35 suspended from the platform so as to be vertical at the desired inclination of the platform. Thus, during raising or lowering of the platform any deviation from the desired inclination operates the appropriate switch to stop movement of the appropriate leg or legs until inclination is corrected by continued movement of the other legs.

Patent GB-2014062-A (GB)
Title: Method and apparatus for separating mixtures or particulate solids
IPC: B03B5/44
Filed: 1979-02-14
Abstract: Mixtures of particulate solids are separated by introducing them to a suspension of magnetic particles in liquid, the particles being of such size that they would tend to flocculate if exposed to a simple constant or alternating magnetic field, flocculation being inhibited by causing the particles to spin. A magnetic field may be applied to enhance the density of the fluid relative to the mixture, and different constituents of the mixture either float or sink and are separately collected. The spin may be imparted by a travelling or rotating magnetic field, which may also serve as the means for creating the enhanced relative density. The travelling field may be provided by a linear magnetic stator (6) with polyphase windings excited from a suitable AC supply (7). <IMAGE>
