Patent GB-2133744-A (GB)
Title: Improvements relating to credit card imprinters
Inventor: MORRIS RAY
IPC: G07F7/08
Filed: 1983-01-14
Abstract: An imprinter has a space 1 for a credit card and also includes a keyboard 6 enabling details of a transaction to be entered, which will be displayed on an electronic display 7. At the same time, and only fan enabling switch 9 has been operated by the insertion of a credit card in the region 1, the amount of the transaction will be set up on a printing head 5. A comparator ensures that the amount entered on the printing head 5 will correspond to that shown on the display 7. A roller of conventional design maybe run over a charge slip placed above the credit card 1 and the printing head 5 so that the relevant details are entered on the slip. <IMAGE>

Patent GB-2118338-A (GB)
Title: Signal processing unit
Inventor: GRAN PAUL
IPC: H04Q9/14
Filed: 1983-03-16
Abstract: A status and control unit, in a supervisory control system, monitors status inputs and transmits messages to a central station indicating the status of these inputs and also has control outputs which may be activated on a command from a central station to provide a control function. In response to a predetermined stimulus such as a change of state at a status input the unit generates a new message for a neighbouring status and control unit by incrementing or decrementing its own address to obtain a new address for transmission. In this way messages may be transmitted between units as well as between the central station and the units thereby allowing communication to units which lie outside the range of the central station itself.

Title: Stretch forming parts from ductile materials
Inventor: MCGOWAN JOSEPH
IPC: B21D25/02
Filed: 1983-08-19
Abstract: A workpiece 1 of sheet metal is gripped around its perimeter by grippers 3, which are in turn pulled by pullers 4, to stretch the workpiece 1 over a former 2. This stretch forming of the workpiece 1 is carried out under the control of a microprocessor 6, which responds to an output of a scanner 12, which monitors the behaviour of the workpiece 1 during its stretch forming. In this way, shaped parts may be repetitively formed, with a high degree of accuracy. The same production machine is capable of producing parts of varying profiles in response to predetermined programmes. The machine will manipulate the workpiece in addition to the stretching of the workpiece because controlled mobility of the mooring points is included. <IMAGE>
Patent GB-2127860-A (GB)
Title: Improvements in and relating to a textile yarn winder
Inventor: HILL GRENVILLE
IPC: B65H54/12
Filed: 1983-09-13
Abstract: This invention relates to textile yarn winding apparatus having a traverse yarn guide mechanism. A problem arises with such apparatus when yarn is being wound onto flanged bobbins since either the yarn guide mechanism has to be positioned above the bobbin, which causes problems when unwinding the yarn, or else there is a gap between the flange and the yarn to prevent the yarn guide engaging the flange. This problem is substantially overcome by the winder of the invention in which the yarn guide is formed of two parts, between which the yarn is guided, the relatively leading part in any yarn guide stroke being movable at or prior to, contact with the bobbin flange to a position clear of the flange so that the relatively trailing part can be moved up to the flange to lay yarn closely adjacent the flange. <IMAGE>

Title: An air cooling and reciprocating type of air compressor without lubricant
Inventor: SONG PO WU
IPC: F04B39/06
Filed: 1985-05-23
Abstract: A cooled compressor is disclosed which needs no lubricant between its piston 3 and its cylinder 2. Piston 3 is driven by rotated shaft 7 via eccentrically located pin 5. Air to be compressed is admitted to the crankcase through a port wherein are located a filter and noise reducing plates. On the piston downstroke air passes through piston port 34 governed by valve 33 and is then compressed during the piston upstroke to the point where spring valve 12 opens to pass the compressed air to outlet 14. Cooling is partly accomplished by the passage of air through the piston, partly by fins 11 and partly by air admitted to funnel 23 being blown around the cylinder. Alternatively water cooling may be used. Piston rings made of polytetrafluoroethylene or graphite may be used to obviate lubrication. <IMAGE>
Patent GB-2180304-A (GB)
Title: Method of fitting a clutch cover assembly
Inventor: CURTIS ANTHONY JOHN
IPC: F16D13/50
Filed: 1985-09-13
Abstract: A clutch cover assembly 4 for a pull-type clutch comprises a cover 16, a diaphragm spring 18 with release fingers 22, and a pressure plate 14 attached to the cover by tangential leaf-springs 30 which pull the pressure plate into the cover 16 when the load of the diaphragm spring 18 on the pressure plate 14 is relieved by a pull on the fingers 22 in direction A. To fit the cover assembly 4 to a flywheel 6, the fingers 22 are pulled in direction A so allowing the release straps 30 to retract the pressure plate 14 into the cover 16. Thus the pressure plate does not press on the clutch driven plate 10 and so there is no opposition by the diaphragm spring to the tightening of the bolts 58 securing the cover 16 to the flywheel. The fitting can be done automatically with a tool 42 which is braced against the cover 16 as a gripping device 46 of the tool pulls back the fingers 22 in direction A. The tool 42, which has a shaft 56 holding the driven plate 10 centrally, offers the cover assembly 4 and driven plate 10 to the flywheel 6 to which the cover 16 is secured by the bolts 58 being automatically inserted and tightened by tool devices 60. <IMAGE>

Title: Apparatus for measuring ground impedance
Inventor: PHILLIPS WILLIAM JOHN
IPC: G01V3/06
Filed: 1988-02-15
Abstract: Apparatus for measuring the complex impedance of the ground comprises a first pair of electrodes (not shown) which in use are driven into the ground, a transmitter (not shown) for applying to the first pair of electrodes a voltage of known frequency and phase, a second pair of electrodes (1, 2) to be driven into the ground at a distance from the first electrodes and a control/monitor unit 4 for measuring the magnitude and phase of the voltage between the second pair of electrodes (1, 2) resulting from the applied field to permit prediction of the ground structure. To reduce measurement errors, a respective buffer amplifier A1, A2 is connected to each of the second electrodes (1, 2) and these are connected to a differential amplifier (D1) for amplifying the difference signal between their outputs by shielded cables of equal length. The arrangement is such that effects of coupling from external magnetic fields are cancelled and capacitive coupling from external sources into the cable is substantially attenuated. Delays in propagating signals from (A1) to (D1) and (A2) to (D1) are matched. A plurality of second pairs of electrodes may be provided which are connected sequentially to a measuring means. One of the buffer amplifiers may be housed with unit (4) and the other remotely located. <IMAGE>
