Title: Improvements in Control Means
Inventor: MADDEN LESLIE JOHN
IPC: E21C35/00
Filed: 1966-01-05
Abstract: 1,170,731. Mineral-mining machines. L. J. MADDEN. 4 April, 1967 [5 Jan., 1966], No. 418/66. Heading E1F. [Also in Divisions Fl and H2] Coal-cutting mechanism mounted on a machine which is traversed along guide rails is driven by an electric motor supplied through cable 22. A split tube 23 and clamps 24 are mounted on the machine for gripping the cable. When the mechanical load on the cable becomes excessive due to entanglement of the cable, lug 28 moves piston 30 against the action of spring 34 or 36, whereby lever 38 actuates a trip mechanism on the machine. This discontinues operation of the cutting mechanism and movement of the machine which may then be reversed to relieve the load on the cable. The control device may be applied to other forms of movable machinery such as excavators, and can also be mounted on a fork lift truck, the cable being used for battery-charging. In further arrangements, the cable is a hydraulic or pneumatic feed-line. As a further alternative, the cutting machine has both an electrical power supply cable and a coolant feed pipe with common or independent gripping means mounted on the machine.

Title: Improvements in and relating to hand-operated die moulding machines
IPC: A21B5/02
Filed: 1956-01-06
Abstract: 839,742. Moulding pies &c. ENTWISTLE, J. April 3, 1957 [Jan. 6, 1956], No. 542/56. Class 87(2). A hand-operated die-moulding machine e.g. a pie-pastry-moulding machine, has a stationary heated die or hollow mould and a complementary hollow mould or die which is non-heated and movable towards or away from the heated member. A non-heated mould holder 32 carries a pie tin 38 and is mounted on a vertically slidable spindle 21 so that by anti-clockwise movement of handle 14 about the axis of a transverse shaft 13, it is raised towards a stationary heated member 24 carrying an interchangeable die 25 complementary to the tin. A crank 15 is located on shaft 13 on said movement, lifts an intermediate lever 17, which is rockably mounted on a transverse pin secured to the base, so that the top of said lever contacts the base of spindle 21 and If its it. The end of the lever 17 adjacent the crank has a curved recess so that when nearly vertical the crank exerts maximum pressure axially of the spindle and the holder 32 decelerates upwardly. A threaded rod (not shown) limits the angular movement of the crank 15 and thus determines the thickness of the pastry. The spindle 21 is moved downwardly by spring 35 and this movement is limited by a projection in the crank engaging a fixed notch. Fig. 4 (not shown), illustrates a hollow die which contains a spring to assist the release of the tin and pastry. Specification 839,741 is referred to.

Title: Improvements in or relating to semiconductor switching arrangements
IPC: H03K17/16
Filed: 1970-01-06
Abstract: 1287392 Semi-conductor switching circuits; pulse modulation circuits LICENTIA-PATENT-VERWALTUNGS GmbH 6 Jan 1970 [11 Jan 1969] 545/70 Headings H3T and H4L A switching circuit has a semi-conductor switching element Z1, Z4 or Z2, Z3 or T1 and a compensating semi-conductor element Z2, Z3 or Z1, Z4 or T2 having similar electrical parameters produced on a single semi-conductor structure and the compensating element Z2, Z3 or Z1, Z4 or T2 in operation is always blocked and is connected such that the signals it passes neutralize, that is, reduce or cancel, the signals passed by the switching element Z1, Z4 or Z2, Z3 or T1 when in its blocked state. Fig. 3 shows a bridge circuit where a blocking potential is applied to A1 and a switching potential is applied to A2 so that transistors Z1 and Z4 conduct signals between a1-b2 and b1-b2. Alternatively by applying the blocking potential to A2 and the switching potential to A1 transistors Z2 and Z3 conduct signals between a1-b2 and b1-a2. In an integrated circuit form of Fig. 3, the resistors R may also be integrated. The above circuit may be used in telephone exchanges. In Fig. 5, for use in an asymmetrical PAM system, the switching transistor T1 connects a filter condenser CF via a resonance coil LR to a bus-bar S, to which a second subscriber is connected. Compensating transistor T2 is provided on a single semi-conductor structure with T1. Transistor T2 is arranged to be blocked by Usp and is connected by a transformer Tr so that when T1 is switched off signals passed by the transistors will be cancelled by the emitter side coupling with respect of the subscriber LR/CF. Thyristors, diodes, field effect and metal layer transistors may be used for the semi-conductor elements.

Title: Improvements in or relating to loudspeaking telephone systems
Inventor: ROSEBY PHILIP NORTON
IPC: H04M1/60
Filed: 1953-01-08
Abstract: 736,988. Two-way transmission. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Nov. 18, 1953 [Jan. 8, 1953], No. 555/53. Class 40 (4). In a telephone.system having voice-operated switching for preventing acoustic reaction between loudspeaker-equipped substations by introducing attenuation in either the incoming or outgoing paths IC, OG of a 4-wire circuit, the line transformers TR1, TR2 have tertiary windings connected through rectifiers MR1, MR2.and smoothing condensers C1, C2 to resistors R3, R4 at which the rectified voltages are combined in opposition to control an attenuation-switching relay SR over a thermionic valve V1. If incoming signals predominate, relay SR releases and closes an attenuating circuit comprising resistor R2 in the outgoing path from a microphone circuit MIC. In this condition the incoming signals are applied directly to an amplifier and loud-speaker circuit LS.over a volumelimiting bridge comprising resistors R7, R8 and metal filament lamps LP1, LP2. When outgoing signals predominate, relay SR is pulled up by increased anode current and closes an attenuating circuit comprising resistor R1 in the incoming path. By arranging the valveoperating conditions to be such that its quiescent anode current is sufficient to hold SR operated but not to pull up the relay if released, the transmission direction which was last in use before cessation of all signals is. maintained. Alternatively the bias of the valve may be adjusted to give priority to one direction of transmission.

Title: Improvements in apparatus for separating the liquid and solid components of mixtures of liquids and crushed or ground ore products
IPC: B01D21/04
Filed: 1922-01-09
Abstract: 195,467. Arbuckle, A. J. Jan. 9, 1922. Separating by gravity.-Separated solid matter is discharged from a settling-tank 2 for ore pulp through a conveyer casing 6 in which is reciprocated a shaft 11 carrying perforated discs 12. The discs are in groups the individual members of which increase in size towards the outlet end of the casing, which is formed as a casting 7 and serves as a feed-chamber for an elevating device in a vertical casing 8. The elevator comprises a shaft 18 with perforated plates 19 of uniform size and provided at suitable positions along its length with valves which open or close according as the shaft is moved downwards or upwards. A ball or other suitable non-return valve 15 is provided at the bottom. The raised material is discharged through a shoot 50. The outlet from the settling-tank to the conveyer 6 is controlled by a valve 51 on a vertically-movable spindle 54, the material being forced past the valve by an annular piece 57 fixed to the spindle. The spindle works through a guide 55, fixed to the wall of the tank, the boss of the guide being protected by an air-tight hood 56 on the spindle. The walls of the tank are scraped by upper and lower sets of curved plates 58 suspended from a tubular member 64 which surrounds the spindle and is lifted by it as the spindle moves upwards. At the bottom of the tube 64 is a cone 79, and any air collected thereby passes away up the tube. The supply pipe 95 may be cone-shaped at top and bottom and may be supported from arms 62 which support the scrapers, so that it is moved up and down with the latter. The moving parts may be actuated from an engine 26 which is connected directly to the shaft 11 and by a rope or chain 82 to the spindle 54. The motion of the shaft 11 is communicated to the shaft 18 by levers 33, 31. In modified apparatus the means for discharging the solid matter are applied to tanks of other shapes. An arrangement is described in which a single conveying and elevating device discharges the solid matter from three settling-tanks. Fig. 17 illustrates the application of the conveying and elevating device to a tank 131 in which ore products and treating solutions are agitated together by means of air under pressure and circulated through a pipe 158. The solution is drawn off through valves 159 and the solid discharged through a conveyer 134 and elevator 136. The moving parts are operated in unison as described above from a crank disc 140.
