Patent GB-2088093-A (GB)
Title: An Automatic Position Control System for Slitters
IPC: B26D7/26
Filed: 1981-11-19
Abstract: An automatic position control system is for a slitter which longitudinally slits a sheet, e.g. of paper, into strips. Each slitter has an upper and lower slitter station which can be moved transversely to the sheet to be cut. Each slitter includes an electronic communication module, an electronic stepping motor drive module, and a stepping motor gear box and pinion assembly for moving the slitter. Each electronic module recognises when a main control computer 53 is communicating with that module by recognising its selectable address. Communication can occur in either direction between the electronic modules and the computer. The computer can command an electronic module to carry out specific functions and also can request information from the electronic module concerning its status at a particular time. Control information can also be supplied to the computer which can rapidly move the slitters to desired locations. <IMAGE>
Patent GB-2116807-A (GB)
Title: Remote switching unit
Inventor: HUGHES JOHN ROGER KERFOOT
IPC: H04M11/00
Filed: 1982-03-03
Abstract: Apparatus for remotely controlling an electrical circuit via a telephone network has a first relay operable to simulate an off-hook condition when a ringing signal is received, a timer which is actuated when the off-hook condition is established, and an output relay for switching the electrical circuit in response to the apparatus remaining connected to a calling telephone for longer than a predetermined period. The apparatus includes a tone generator for indicating the state of the output relay to the caller. Disconnection of the calling telephone is detected by sensing the dialling tone. Switching of the electrical circuit therefore only occurs if the caller waits until the tone transmitted by the tone generator indicates that the circuit has been switched.

Title: Semiconductor device and method of manufacture
Inventor: RYNNE D MICHAEL
IPC: H01L29/73
Filed: 1982-09-21
Abstract: Regions of semiconductor material are separated by grooves, an insulating layer (107) is then formed on the surface of the semiconductor material including the surfaces of the grooves, and polyimide material (108) is formed over the top surface of the insulating layer and the grooves to fill the grooves and to provide a substantially smooth top surface over the structure. An interconnective material (111) such as aluminium is then formed over the polyimide material and contacts active regions (103, 104) in the underlying islands of semiconductor material through vias (120, 121) formed in the polyimide material and the insulating layer. Polyimide is applied to the device in a low temperature process, so the PN junctions defining the active regions of the device are not altered by any high temperature, long duration, thermal oxidation processes and thus device characteristics and yield are improved over prior art structures. <IMAGE>

Title: Mos transistor integrated circuit with apertured contact sheets
Inventor: CLARKE PATRICK WILLIAM
IPC: H01L29/78
Filed: 1983-08-25
Abstract: In power MOSFETS, lead resistance loss is an important device design consideration. These devices typically use, for gate electrodes (15), sheets of polysilicon in order to provide low input impedance. Likewise, the source electrodes (17) are integrated together in a sheet-like structure. According to the invention, the sheet electrodes (15, 17) are perforated (18, 19) to improve the high frequency performance of the device by reducing interelectrode capacitance. <IMAGE>

Title: Method and apparatus for assessing the structure and mechanical integrity of osseous systems
Inventor: MINTOWT-CZYZ WITEK
IPC: A61B5/103
Filed: 1984-08-23
Abstract: A method and apparatus for assessing the mechanical and structural integrity of osseous systems for example the progress to completion of fracture union of a fractured bone. The method involves stimulating the bone to set up vibrations in the bone and then monitoring the resulting vibrations from the bone in such away that an accurate assessment of the integrity of the bone can be made. This may be done by either stimulating the bone by mechanical impulse and detecting the changes in transmission of vibration from one point to another in the bone, or stimulating the bone with a sinusoidal wave form and monitoring the changes in resonant frequencies of the bone parts under investigation. The disclosed invention has the attributes that it yields a measure of the mechanical state of bone and that measure is quantitative. Moreover it yields data of similar quality whether the bone is intact, disrupted, healing or the site of an implant, splint or prosthesis of whatever material, and has applications ass research tool or clinical monitor of skeletal changes. <IMAGE>

Patent GB-2153921-A (GB)
Title: Pumping and mixing apparatus
Inventor: SPENCER DENNIS LINCOLN
IPC: F01B21/02
Filed: 1985-01-17
Abstract: Linked pistons 24,24' caused to reciprocate by supplying fluid alternately to chambers 26,26', drive the linked bucket pistons 44,44' so that closing fluid admitted through valves 54,54' is accurately metered into chambers 26,26' and mixed with the main fluid. The dose is set by adjusting the length of the setting screws 56,56'. The alternating fluid supply is produced by valve 12, which responds to the drop in pressure in channel 64 or 64' occurring when the corresponding piston 24 or 24' reaches its inward end of stroke. This drop causes flexible diaphragm 86 to bend towards the low pressure side and carry rod 68, bearing spool valves 70,70', with it, so connecting the exhausted chamber 26 or 26' with the supply port 60 or 60' and the full one with drain 62 or 62'. The valve rod is held in its position by magnet 92 or 92'. In another arrangement, the pressure change is used to drive a pilot valve which governs pilot pressure acting on the main changeover valve (Fig. 2, not shown). <IMAGE>

Title: Flame spraying gun
Inventor: THOMAS NORMAN DOUGLAS
IPC: B05B7/20
Filed: 1985-03-19
Abstract: A flame spray gun for spraying pulverulent material is connectible to an unsealed powder hopper from which powder is in use disposed into a mixer body forming part of an injector unit. A nozzle connected to a source of compressed air projects into the mixer body and entrains powder.

Title: Injection moulding
Inventor: BARRETT MALCOLM TERENCE
IPC: B29C45/57
Filed: 1986-03-03
Abstract: A hot runner system unit 3 for use in thermoplastic injection moulding comprises a main flow path 7 which is connected at one end with a cold runner 9 in a mould 1 and which is connected at its outer end 13 with an injection device (not shown).

Title: Control system for a plurality of irrigation sprinklers
Inventor: KITCHING ROGER WILLIAM
IPC: A01G25/16
Filed: 1986-07-10
Abstract: An electrical control system for a plurality of irrigation sprinklers supplied by a water distribution pipe-line from a common pump 2. Each sprinkler 1 or group of interconnected sprinklers 1,1', 1'' is supplied through an individual branch pipe 4 from a main supply pipe 3 leading from the common pump 2. Each branch pipe 4 contains a solenoid-operable on/off valve 5 controlled by electrical controller 6. This may be a solid state electronic type. A pressure responsive switch 8 is set override opening of the valve 5 by the controller 6 when the delivery pressure in branch pipe 4 falls below the predetermined pressure for efficient sprinkling. With this system there is only a need for electrical cables between each solenoid valve 5 and the respective controller 6, there being no electrical cables between the controllers 6 and the pump 2. Thus long lengths of cable and consequent loss of control signals are avoided. <IMAGE>
