Title: Dusting suppressing mineral mining cutter head
Inventor: BINGHAM TERENCE RONALD
IPC: E21C35/187
Filed: 1982-08-25
Abstract: A cutting head (1) for a mineral mining machine has a plurality of pick boxes (2) each capable of receiving and retaining a radial pick (15) having a water passage (20) extending through the body of an inner end to a location behind a cutting edge (16) of the pick. Each pick box has a housing (8) at the base thereof into which a water passage (7) through the cutting head opens. An elongate jet (12) having a water passage (14) extending longitudinally therethrough is retained and sealed within the housing (8) so as to be capable of limited universal movement relative thereto. A first end of the jet communicates with the water passage (7) through the cutting head and the jet projects generally radially outwardly from the housing into the pick box to be received in a bore (18) in the inner end of a pick. The jet is sealed in the bore by a seal (19) and communicates with the water passage (20) through the pick. The limited universal movement of the jet which is provided by the seals allows movement of the jet as the pick wears in the pick box while retaining the integrity of the water passage. <IMAGE>

Patent GB-2142489-A (GB)
Title: Low power consumption electronic circuit
Inventor: YAMASHIRO OSAMU
IPC: G04G19/00
Filed: 1983-10-12
Abstract: According to the present invention, the voltage of a battery is supplied to an electronic circuit such as a watch circuit through a step down circuit which is constructed of capacitors and switching MIDFETs. The step down circuit performs a current converting operation as well as a voltage converting operation. The operating current of the electronic circuit is reduced by the reduction in the operating voltage of the same. As a result that the operating current level of the electronic circuit is dropped and that the current conversion is performed by the step down circuit, the battery current is relatively largely dropped. The construction thus far described elongates the lifetime of the battery. According to the present invention, therefore, there is provided a circuit which is proper for driving the step down circuit.

Patent GB-2257252-A (GB)
Title: Target detection sonobouy
Inventor: BURRELL GEOFFREY JOHN
IPC: G01S11/14
Filed: 1984-03-07
Abstract: A target detection sonobouy 1 contains some signal processing capability so as to eliminate non-target data and thereby reduce the amount of data which the buoy needs to transmit. The sonobouy 1 comprises a narrow band receiver 3 arranged to have a plurality of spectral cells 4 across its bandwidth. The output from the receiver 3 is passed through a threshold detector 5 to a Doppler signal processor 6. The Doppler processor 6 produces an output signal when the input signal satisfies predetermined Doppler criteria of monotonic movement of the received signal across the spectral cells 4 of the receiver 3. The sonobuoy includes a transmitter 7 arranged to periodically sample the received background noise signal and to 12 transmit the Doppler/threshold selected target signals. The transmitter 7 is arranged to transmit coded information on a single frequency repeatedly with random time intervals to minimise interference with similar sonobuoy transmissions in a multi-sonobuoy detection array. <IMAGE>

Patent GB-2143075-A (GB)
Title: Lasers
Inventor: BOWES DONALD
IPC: B23K26/10
Filed: 1984-05-04
Abstract: A gas laser 10 has a support tube 40 supporting and maintaining the alignment of the optical resonator structure 24, the tube containing active medium and being in communication with the discharge tube 26 in which lasing occurs. An active temperature controller maintains the lasing medium in the tube (40) at a substantially constant temperature above ambient by means of a temperature sensor 20 and a servo 22. An active pressure controller uses a pressure sensor 30, an electronic processor, and a motor-driven needle valve 14 to maintain the pressure of the lasing medium in the laser 10 within the desired operating pressure range. The laser 10 can be switched in operation from a continuous mode to a pulsing mode by using switches to create an asymmetrical flux pattern in the transformer of a power supply system. An active power control system maintains the power output of the laser at the desired level through an active feedback loop in which the output beam is used to generate a voltage signal for control of discharge current. Because the optical resonator structure 24 is lightweight, it can be mounted on a movable mechanical assembly (155) for delivery of the beam to a desired location. The assembly includes linked relatively movable members with reflecting mirrors in the joints for transmitting the beam. The laser may form part of a distributive lasing system comprising a centralized pump 36 delivering the lasing medium to a plurality of remotely located optical resonator structures 24, each of which may have a separate heat exchanger 18. <IMAGE>

Title: Stepping drive mechanism
Inventor: CHEESEMAN ROBERT ANDREW
IPC: F16H27/10
Filed: 1984-07-02
Abstract: A stepping drive device, suitable for driving the rotor (2) of a peristaltic pump (3) used to deliver fuser oil to a dispensing wick in contact with the heated fuser rollers in a xerographic copying machine. A ratchet and pawl mechanism (1) includes a shield member (35) having a window through which the pawl (26) can engage the ratchet wheel (24). In a first mode of operation, the pawl is prevented from engaging the ratchet wheel over part of its movement by the shield (35). Towards the end of its movement, the pawl drops through the window and advances the ratchet wheel by, for example, one tooth. In a second mode of operation, the shield member is rotated so that the pawl can engage the ratchet wheel through the window earlier in its movement. In this way, the pawl advances the ratchet wheel by several teeth. The device allows two different amounts of output movement for a given input movement. <IMAGE>

Title: Gas-fired heating appliance
Inventor: CHESWORTH ARTHUR
IPC: B60H1/22
Filed: 1984-10-23
Abstract: A caravan has a gas-fired convector heater (11) mounted on an internal wall. A balanced flue for the heater comprises a first combined section comprising an inner exhaust duct (16) and an outer air inlet duct (17). The ducts then separate, the exhaust duct extending upwardly through the roof of the caravan, the air duct extending downwardly through the floor.

Title: A process for forming waste plastics material into an article
Inventor: BUNYAN RICHARD J
IPC: B29C48/09
Filed: 1985-10-21
Abstract: The process comprises the steps of feeding the waste plastics material into a housing having a rotatable screw member and then mixing the material in the housing until the material becomes flowable. The flowable material is then transferred by means of a screw member via a hole in the housing into a mould having a heating means operatively associated therewith. The internal temperature of the mould is substantially the same as the temperature of the flowable material so that the flowable material takes up the internal shape of the mould. The mould is allowed to cool to enable the material to set and then the article is removed from the mould. In a preferred embodiment, the moulds (52-59) mounted on a rotatable mould holder, are successively pushed against the outlet of the housing. A heater assembly (6) is lowered by a ram (17) so that the heater frame (6b) contacts the mould. The mould is filled, the heater removed and the mould then passes successively to the cooling tank (4), followed by removal of the moulded article (59). <IMAGE>
