Patent GB-2069341-A (GB)
Title: Breathing Apparatus
IPC: B63C11/24
Filed: 1981-02-04
Abstract: Semi-closed circuit re-generative breathing apparatus for use by divers wherein the flow of gas into the breathing circuit is automatically adjusted to suit the pressure at the depth that a diver happens to be and which compensates for variation in the pressure of gas supply to the apparatus from an external source. This is met by having mass reducing means for gas admitted to the breathing circuit sensitive to external pressure with the mass being decreased as the dive depth increases, and whereby the oxygen partial pressure in the breathing circuit is maintained between 0.16 and 2.0 atmospheres. <IMAGE>
Patent GB-810798-A (GB)
Abstract: 810,798. Calculating-apparatus. BURROUGHS CORPORATION. July 10, 1956 [July 18, 1955], No. 4131/57. Divided out of 810,797. Drawings to Specification. Class 106(1). In an accounting machine having a movable paper carriage and means, controlled by the carriage according to its columnar position, to disable normally operating tabulating or carriage return mechanism, the disabling means are themselves disabled by certain manipulative members. The arrangements disclosed are fully described in Specification 810,797, [Group XVI], and comprise two control mechanisms. By means of the first, the lane 19 carriage control, which causes line-spacing and prevents tabulation, is disabled when the machine cycle is initiated by the crossfooter (front) totalizer sub-total key or by either of the " Skip " or " Return " motor bars. The lane 19 control facilitates the listing of items, e.g. cheques, on a tally strip, depression of the sub-total key causing a skip-tabulation to an item column. By means of the second control, the " Return " motor bar may be used to cause a skip-tabulation, after the last of a series of items has been entered in an item column, to a New Balance column, this movement taking place from a column in which a lane 20 control normally disables the carriage return mechanism but is itself disabled on depression of the sub-total key so that a return to the Old Balance column will follow a sub-total operation. Specification 709,181 also is referred to.

Title: Wheel truck for supporting the flat or damaged tyre of a vehicle
Inventor: MURILLO HERNANDO
IPC: B66F7/24
Filed: 1981-11-06
Abstract: The small, compact, collapsible three-wheeled truck has a foldable ramp (12) which rests flat on the ground while the rear wheels (3) are in slightly raised position, so as to prevent movement of the truck while the flat tyre is being driven onto it. As the ramp (12) pivots upwardly into retaining position behind the tyre, the rear wheels (3) are lowered into ground contacting position. Simultaneously, an extension (15) attached to the ramp causes a retaining member near the front of the truck (10) to pivot upwardly out of the way of the approaching tyre into the front retaining position. The tyre after mounting, rests in a cradle (11) and is prevented from moving forwardly or rearwardly with respect to the truck. <IMAGE>

Filed: 1982-07-13
Abstract: A VLSI device is formed on monocrystalline silicon and comprises FET's (G, S, D) and diffused connections 101 surrounded by field oxide and polysilicon interconnections 102. First oxide and nitride layers are formed (for the gate insulator) and doped polysilicon is applied, oxidised to a second oxide layer and covered with a second nitride layer which is oxidised to an oxynitride layer. The last two layers are masked and etched except where polysilicon contacts 103 are required. A third silicon nitride layer is applied and oxidised to an oxynitride layer and these layers are masked and etched to define the polysilicon connection 102 including gate electrodes G. Then the exposed second nitride with its oxynitride and then polysilicon are removed. The first nitride and its oxynitride are masked and etched to define the FET areas 405 and diffused line contact areas 406. Batch etching steps are followed by doping the diffused and polysilicon lines 101, 102 thereby exposed. More batch etching steps are followed by doping the source and drain regions thereby exposed. Oxide is removed from contact areas Pc, Nc and interconnection lines are applied. <IMAGE>

Title: Beamrider guidance system using digital phase modulation encoding
Inventor: LAYTON ALLEN C
IPC: F41G7/26
Filed: 1982-10-26
Abstract: A beam of electromagnetic radiation is spatially encoded 20 using a digital phase modulation technique. The spatial encoding defines the beam cross section into a series of resolution elements each identified by a different digital code. The codes defining resolution elements are detectable by a missile 11 located in the radiation beam and can be used to define the location of the missile in this bean. An encoding mask 24V, 24H, moved through the beam at its source, provides the digital phase modulation, and is provided with a series of bit areas, each of which bears at least two sets of cyclically recurring bands effective to modulate a detectable parameter of the radiation, such as intensity. The spacing between adjacent bands of a set, termed a bit cycle, is proportional to a predetermined phase of the modulation of the beam parameter.

Title: Improvements in or relating to water level control
Inventor: GODWIN JULIAN RICHARD
IPC: E02B7/44
Filed: 1983-10-12
Abstract: A pivotable water level control gate set in a waterway is coupled to a rotatable float 10, partially immersed in a float chamber connected to the waterway. The float responds by motion about its rotational axis 14 to a change in water level and thereby operates the gate to adjust the water flow in accordance with the water level change. The float has a sealed buoyancy chamber 15, a constant mass part 16 which may be a chamber filled with a fixed volume of water, and optionally a third mass 17, again a water-filled chamber. The float construction ensures the metercentre close to the centre of mass so that small water level changes produce large control movements. The float may operate the gate via a pulley system or the gate is coupled to pivot with the float. <IMAGE>

Title: Soil cultivating implements
Inventor: VAN DER LELY ARY
IPC: A01B49/02
Filed: 1984-06-14
Abstract: A soil cultivating implement comprises power-rotatable soil working members 3 and a ground roller 10 and a soil accumulating or capturing member 23. In order to prevent the member 23 moving downwardly when large volumes of soil are displaced by the tines 5, said member 23 is carried by arms 22 which are connected to plates 16 carried by the frame portion 1 by two pivotable polygonal linkages 24 which can, as illustrated, be in the form of parallelogram linkages. The leading pivot pins 17 of linkages 24 are in advance of a plane containing the axes of rotation a of the soil working members 3. This allows the member 23 readily to move upwards without significantly tilting and thus losing its uniform soil distributing and further soil crumbling effects. Weight-relieving springs 29 interconnect the linkages 24 and brackets 27 carried by the frame portion 1. <IMAGE>
