Title: An electrode array for muscle stimulation and recording
Inventor: HODGSON JOHN ASHWORTH
IPC: A61N1/04
Filed: 1984-05-10
Abstract: A flexible backing pad 10 bears a spaced pair of recording electrodes R at right angles to a spaced pair of stimulating electrodes S. The recording electrodes R may have associated signal ground electrodes G. The array is attachable to mammalian skin over a muscle so that the recording electrodes pick up electrical muscle activity. A resulting signal is fed to processing apparatus which generates a stimulating signal and feeds it to the stimulating electrodes S. The electrode array is arranged to minimise direct influence of the stimulating signal on the recording electrodes R. <IMAGE>

Title: Controlling artificial lift in wells
Inventor: HOPPER HANS PAUL
IPC: E21B43/017
Filed: 1987-11-12
Abstract: Crude oil production from a well is stimulated by artificial lift. To control the artificial lift and hence the production of oil, a choke unit 112 associated with a natural flow production well is modified so that the artificial lift fluid is passed through the choke 212 itself and the crude oil is passed around but not through the choke. The choke unit may be modified by inserting a spool 209 below the choke itself, the spool defining passages which lead the artificial lift fluid into the choke and the oil to bypass the choke. The spool may also have a port 210 in the crude oil passage for the injection of chemical fluid. <IMAGE>

Patent GB-880608-A (GB)
Abstract: 880,608. Calculating-machines; transfer mechanisms. PENN INVENTIONS Ltd. Nov. 20, 1959 [Nov. 27, 1958], No. 38318/58. Class 106 (1). An adding device having registering discs on parallel shafts has transfer mechanism between each pair of discs comprising a lever which is moved gradually against the action of a spring or weight during rotation of the lower order disc through several digital positions and then suddenly released to effect transfer, a transfer pawl carried by the lever acting to prevent further rotation of the higher-order disc after transfer is completed. The discs 4, 5 and 6 of a device for adding Sterling amounts have holes 7 by which they are settable using a stylus 8. The number registered by a disc is indicated through a hole 20 in the disc. An overflow order pointer 10 is advanced one step for each ú20. Transfer mechanism.-Before transfer, two pins 31 in a lower order wheel 51, fixed on the same shaft as its disc 4, rock a lever 27 against a spring 30. At transfer, the lever drops off the second pin and the transfer pawl 28 carried by the lever advances the higher order wheel one step. The pawls and wheel are shaped to prevent overthrow, or the pawl 280, Fig. 4, may move against a fixed pin 33. In this case, the lever 270 is arranged to overthrow its rest position, under its own momentum, to ensure the abutment of the pawl against the pin 33, and is then slightly withdrawn by a spring 34 to free the pawl.

Patent GB-2206211-A (GB)
Title: Sensor circuit
Inventor: BILLINGSLEY JOHN
IPC: G01N27/04
Filed: 1988-06-09
Abstract: A sensor interface arrangement comprises a first reference sensor R1 and a second sensor R2 for detecting a physical parameter (e.g. humidity) to be measured, first and second resistors R3 and R4 connected in parallel with the sensors via a normally closed switch 1, a capacitor C being connected across resistor R3, it being arranged that the voltage across the capacitor C is one or two percent greater than the voltage across the resistor R2, a comparator for comparing the voltage at the junction of the sensors R1 and R2 with the voltage at the junction of the resistors R3 and R4, the comparator affording an output to a microcomputer 4 which is effective for operating the normally closed switch 1. When a physical parameter is to be measured, the switch 1 is opened by the microcomputer 4 whereby the voltage on the capacitor C begins to decay. When the voltage across the capacitor C equals the voltage at the junction of the sensors the comparator operates and affords an output to the microcomputer. The time interval between the time the switch 1 is operated and the time the comparator operates is indicative of the physical parameter being sensed. Applications to strain gauges and to temperature sensing are also envisaged. <IMAGE>

Title: Address translation for I/O controller
Inventor: FROST ADRIAN RICHARD
IPC: G06F12/02
Filed: 1989-05-12
Abstract: A data processing system includes a central processing unit (CPU), 10, a main memory 11 and an input/output (IO) controller 14. The CPU addresses the memory by means of a virtual address, which is translated into a physical address by a memory management unit (MMU) 13. The IO controller also addresses the memory by a virtual address, which is translated by a separate MMU 17. The use of virtual addresses by the IO controller allows an IO buffer area in the memory to appear as contiguous range of addresses, even though it is in fact fragmented. <IMAGE>

Patent GB-2238329-A (GB)
Title: Building panel
Inventor: PITTS GEOFFREY CHARLES
IPC: E04B1/10
Filed: 1989-11-14
Abstract: A prefabricated building panel has insulation 36, an outer wall 52 comprising moisture-resistant and fire-resistant material, for example plasterboard, and an inner wall 54 of structural boarding, for example plywood, such that the outer wall has a lower vapour resistance than the outer wall. The internal plywood sheathing provides lateral bracing for the panel which, in earlier designs, was previously provided on the outside (Fig. 1). The relatively high vapour resistance of plywood, in comparison with that of the external moisture-resistant plasterboard, means that airborne water vapour will naturally pass through the wall to the exterior. No separate breather membrane or vapour barrier is required. There is also disclosed a building structure using a pair of such panels which abut each other 74 so ensuring that the integrity of the wall insulation is not broken by the intermediate floor 14 or the joists 10, 12. <IMAGE>

IPC: B26B21/22
Filed: 1989-12-01
Abstract: A safety razor (1 Fig 1) comprises a handle (2) having a head portion (3) and an exchangeable razor blade assembly (6). Disposed within the head portion (3) is a bifurcated holder 5 comprising a base plate (11 Fig 6) two lateral arms 13 integral with the base plate (11) via webs (12 Fig 6) and a displacing element 9 in the form of a portion of the base plate (11) accessible at an exterior surface of the head portion (3). Movement of the displacing element 9 with respect to the head portion (3) causes movement of the bifurcated holder 5 from a first position in which the arms 13 engage the razor blade assembly (6) to a second position in which the arms 13 are pivoted so as to release the razor blade assembly (6) in order that another razor blade assembly (6) may be substituted. Teeth 19 laterally of the resilient tongue 17 forming element 9 are released from rear recesses (25, Fig 10) by downward pressure on the tongue, and forward movement of the tongue causes projections (16, Fig 6) to move along oblique slots (24 Fig 9) to spread arms 13, the teeth engaging forward recesses (25). <IMAGE>

Title: Internal cutting tool and holder
Inventor: SEIFERMANN NORBERT
IPC: B23B29/04
Filed: 1990-02-28
Abstract: The holder 10 is associated with the hook-ended tool 11, having a shank 12 clampable in a receiving holder recess 21 by a clamping means, for example, a screw. Diametrically opposite the clamping means, the receiving recess 21 has a radial extension 22 for a radial projection 17 on the shank 12 of the hook-ended tool 11. When the shank 12 is clamped in the holder 10, the radial projection 17 abuts on clamping surfaces 23 of the extension 22 which converge radially outwardly and precisely define the position of the hook-ended tool. The respective surfaces may be flat with a groove cut into one clamping surface 23 to provide for three-point contact. Alternatively the clamping or projection surfaces are concave and convex with the other surfaces flat, to provide the three-point contact. Coolant can be supplied through a bore 19. <IMAGE>
