Title: Temperature compensating spacer
IPC: F16B1/00
Filed: 1980-11-01
Abstract: A thermally responsive spacer means, which may be a washer 17, for use in a clamped assembly such as nut 13 and bolt 14 securing components 11 and 12, comprises at least two members 18, 19, which in use have mutually contacting faces angled to the direction of action of the clamping forces and made of materials of different coefficients of thermal expansion chosen such that either: member 18 expands radially faster than member 19 and is forced radially outwards to reduce the longitudinal dimension of the spacer; or such that member 18 expands slower than member 19 and thus contracts radially thus increasing the longitudinal dimension in order to compensate for the differential thermal expansions of the components 11, 12 and the bolt 14 in that direction. The spacer can comprise three members retained in a sheet metal housing (fig. 2). <IMAGE>

Title: Support means for supporting planks on ladders
IPC: E06C7/16
Filed: 1981-01-05
Abstract: An elongate object, for example a plank (4) is releasably clamped to a ladder or ladder-like frame between a rung (1) and a pair of elongate clamp bars (8). A pair of U-shaped bolts (6) straddle the rung (1). Threaded ends of the limbs (7) of the bolts (6) pass through openings (9) in the clamp bars (8). Wing-nuts are screwed onto the ends of the bolts (6) and are tightened so as to act through tubular thrust transmitting spacers (11) to urge the bars (8) and plank (4) into engagement with the rung (1), thus clamping the plank (4) substantially against lengthwise movement. The clamp bars (8) extend to the outer ends of stiles (3), and the stiles are firmly clamped between the bars (8) thus preventing angular movement of the plank (4) with respect to the rung. <IMAGE>

Title: Automatic safety gas heating device
IPC: F23N5/02
Filed: 1981-05-26
Abstract: Unlike directly controlling a valve of the gas conduit in the conventional gas heating device, a valve rod 3 which is connecting to a diaphragm valve 1 merely actuates a microswitch 4 for electric control board 11. A first gas conduit and a second gas conduit which communicate separately with the nozzle 14 of a pilot burner and the nozzles of a main burner 18, are controlled respectively by a first solenoid operated valve 5 and a second solenoid operated valve 6. In the vicinity of the nozzle 14 of the pilot burner, a sensor 16 is provided for detecting the presence of the flame 15 of the pilot burner. As the flame 15 of the pilot burner is ignited by the igniter 12, the sensor 16 will send a first electric signal to the electric control board 11 to discontinue the sparkling of the igniter 12, and to open the second solenoid operated valve 6 and supply the gas to the main burner 18. As the flame is undesirably blown out during the use of gas heating device, the sensor 16 will send a second electric signal to the electric control board 11 to continue the sparkling of the igniter 12, and to actuate the second solenoid operated valve 6 and stop the gas supply to the main burner 18 so as to prevent the unburned toxic gas from flowing out of the nozzle thereof. <IMAGE>

Title: Method and apparatus for measuring thermal neutron characteristics
Inventor: JOHNSTONE CHARLES W
IPC: G01V5/10
Filed: 1982-10-08
Abstract: The thermal neutron decay characteristics of an earth formation are measured by detecting indications of the thermal neutron concentration in the formation during a selected set of two measurement intervals following irradiation of the formation with a burst of fast neutrons. These measurement intervals may comprise a sequence of time gates following a delay after the neutron burst. The duration of the neutron bursts, of the delay between the burst and the start of the sequence, and of the individual time gates, may all be adjusted by a common, selected one of a finite number of scale factor values. The set of two measurement intervals is selected from among a number of possible sets as a function of a previously measured value of the decay characteristic. Each measurement interval set is used over only a specific range of decay characteristic values for which it has been determined, in accordance with a previously established relationship between the decay characteristic value and a function of the thermal neutron concentration measurements for the set, to afford enhanced statistical accuracy in the measured value of the decay characteristic. <IMAGE>

Title: Calendering sheet paper
Inventor: MATSUMOTO KIYOSHI
IPC: D21H25/14
Filed: 1983-03-03
Abstract: Sheet paper covered with synthetic resin is inserted between a metallic endless belt 14 and press roller 16. The metallic endless belt is wound around and heated by main roller 18 in which a thermal fluid such as steam of oil is circulated. The sheet paper heated by conductive heat of the thermal fluid is then cooled by the endless belt 14 which is cooled by cold water shower 28 and, finally, the sheet paper is peeled off from the endless belt. In this way, construction of calendering apparatus can be simplified and an improved heat control can be realized. Furthermore, the sheet paper covered with synthetic resin can uniformly be heated and, thereby, calendering effect can be enhanced. <IMAGE>

Title: Apparatus and method for processing data arrays
Inventor: FOUNTAIN TERENCE JAMES
IPC: G06T9/20
Filed: 1983-05-27
Abstract: For speed in image processing it is advantageous to have one processor for each element of a data array which is to be processed. However arrays of processor cells become expensive when data arrays become large. An alternative is to scan a large data array with a small cell array but problems then arise where data elements needed in a partial scan are outside the current partial scan. In the apparatus described groups of processor cells 13 to 16 form a cell array, with similar groups, for scanning a data array, and to overcome the above mentioned problem, edge-signal stores 17 to 20 are provided. These stores hold signals relating to information in the data array just outside the current partial scan or processed information required for the next partial scan. In propagation processing time is saved by passing processed information from edge-signal stores in a leading edge of the cell array in scanning to edge-signal stores in the trailing edge by way of paths 48 and 49. <IMAGE>

Abstract: An arrangement is provided for controlling the direction of a towed vehicle having an angularly displaceable wheel, in response to the direction of a towing vehicle which is connected to the towed vehicle. A trailing (2) carries steerable wheels operatively connected to a reversible motor (6). The motor (6) is controlled by power relays in response to signals from a linearly variable potentiometer or an optical linear displacement transducer (11) which senses the portion of the steerable wheels, and from a rotary variable potentiometer or an optical angular displacement transducer (12) which senses turning of the trailer relative to the towing vehicle 3. The combination of towed and towing vehicle then exhibits, when reversing, the steering characteristics of a single vehicle having a wheel base comparable to that of the combination. In another embodiment the transducers sense turning of the steerable wheels on the trailer and on the towing vehicle respectively. <IMAGE>

Title: Oxygen sensor
Inventor: PARKER DR DAWOOD
IPC: G01N27/49
Filed: 1983-06-30
Abstract: A polarographic oxygen sensor intended primarily for measuring levels of oxygen in blood during by- pass surgery has a sensor body comprising a rod-like cathode 12 mounted in a tubular anode 10, an electrolyte film covering flush end surfaces of the cathode and the anode, and a low oxygen permeability membrane 22 trapping the electrolyte on the sensor body. The preferred material for the membrane is a polypropylene film. By using a relatively low permeability membrane, the cathode can be made significantly larger and hence less expensively than in prior art sensors without creating unwanted consumption of the oxygen being measured. The sensor is potted in a standard conduit section 26, the combination of the two constituting a sterile, disposable item. An electrical connector or cable termination includes contact elements for engaging the electrodes of the sensor. One of the elements has a recess for a thermistor which is in close thermal contact with the cathode when fastened to the sensor so that the temperature of the blood in close promixity to the sensor can be accurately monitored simultaneously with the oxygen level. <IMAGE>
