Title: Improvements in or relating to dry gas meters
Inventor: ALEXANDER ARTHUR
IPC: G01F3/22
Filed: 1959-12-09
Abstract: 917,107. Integrating-apparatus. PARKINSON COWAN Ltd. Nov. 30, 1960 [Dec. 9, 1959], No. 41907/59. Class 106 (4). A dry gas meter has a shaft 10 driven by the metering mechanism, a pawl 14 mounted on a radial arm 12 rotating with the shaft 10, a ratchet-wheel 16 which can be engaged by the pawl to drive indicating mechanism 24 and a device 26, 27, 28, 29, responsive to changes of temperature for intermittently interrupting the engagement between the pawl-and-ratchet wheel to provide a temperature compensated indication. The device comprises an arcuate shroud 26 carried by a fixed bushing 27 and a similar shroud 28 carried by a bushing rotatable in the bushing 27. A bimetallic spiral 29 is fixed at one end to the bushing 27 by a screw 30 and at the other to the shroud 28 which it will rotate as the temperature varies to vary the number of teeth of the ratchet-wheel 16 which are covered jointly by the two shrouds 26, 28. When a pin 15 on the pawl 14 encounters the rounded end of shroud 26, it rocks the pawl 14, against the action of a spring, out of engagement with the ratchet-wheel 16 and when the pin 15 drops off the end of shroud 28 the spring brings the pawl 14 back into engagement with the ratchet-wheel 16. Thus, the drive from the meter shaft 10 to the indicator 24 is interrupted for a fraction of each revolution determined by the temperature.

Abstract: 1415525 Dock gates MAUNSELL & PARTNERS PTY Ltd 11 Sept 1973 [11 Sept 1972] 42016/72 Heading E1H A dock gate 1 of the flap type pivots about horizontal hinges connected to its lower edge and has bearing surfaces 6, 7 which engage surfaces 9 and 21 of a claw 10 formed in the sill 20 of the dock. The surface 7 has a bearing strip (8) (not shown) which, together with rubber quoin seals (16) (not shown) abutting the sides of the dock, seal the gate 1 when it is closed. The gate is raised or lowered in a preferred embodiment by emptying or flooding respectively one or more ballast tanks 13 located within the gate 1 below the low water level and a further ballast tank 14 is located along the lower edge of the gate, the tank 14 providing buoyancy when stepping or unstepping the gate 1, but being normally flooded. The upper edge of the gate I has a roadway or walkway 15 and a trash flap 22 to protect the seal between the surfaces 9 and 7. The surface 6 may also be provided with a seal and an auxiliary seal (23) (not shown) provided on the outer (with respect to the dock) surface of the gate 1 so that when the gate is closed, the claw 10 may be drained, access to the claw 10 being provided by a shaft in the dockside. When the gate I is opened it is stowed in a well 25 extending outwardly from the dock entrance and having a shock absorber 27. In alternative constructions, the hinges, about which the gale pivots, are located in the claw 10 and a buoyancy tank is located either within but on the outer side of the gate or externally of and attached to the outer surface of the gate so as to provide a turning moment about the hinges. The gate may be open and closed by mechanical means either instead of or in combination with the buoyancy tanks.

In unit air conditioning apparatus comprising the evaporator 5 and condenser 6 of a refrigerating system a stream of air to be conditioned is passed over the evaporator and a cooling air stream is passed over the condenser, the separate air streams being produced by a single fan 8. Room air passes through a channel 3 in a casing 1, which channel includes filters 14a, 14b, and an electric heater 15a or a hot water or steam heater 15b, while outside air passes through a channel 4 which includes the refrigerant compressor 7. A centrally pivoted damper plate 18 on the upstream side of fan 8 is provided to regulate the amount of outside air from channel 4 which may be mixed with room air in channel 3. The condenser 6 and evaporator 5 are separated by a wall 20 on the downstream side of the fan, the wall being of porous material to allow condensate to drain away from the evaporator. Alternatively, a drainage path for condensate is provided by interweaving a water permeable cord with the coils of the evaporator and condenser. The wall 20 may consist of two relatively movable parts for varying the relative proportion of air supplied to the condenser and evaporator.

Abstract: A doped semi-conductor rod is zone-melted while held at each end in a vacuum of less than 10-3 mm.  Hg, the molten zone being maintained of constant length and being passed along the road at a speed of less than 1,4 mm./minute preferably 0,7-1,2 mm./minute, so as to produce a uniform concentration of doping agent throughout the length of the rod.

Title: Improvements in or relating to Semiconductor Devices

Abstract: 1,180,758. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 21 Sept., 1967 [21 Sept., 1966], No. 43023/67. Heading H1K. A semi-conductor device including a lightemitting PN junction has contacts suitably disposed for adjusting the lateral current in regions adjacent the junction to control the area of light emission along the junction. The term "light" includes all photon emission. In one embodiment a device 10 made of Si, GaAs, or GaP has a light-emitting PN junction 18, a contact 28 on an N-type region 12, and a pair of contacts 24, 26 on a P-type region 14. By biasing one of the contacts 24, 26 relative to the contact 28 and opening the other, junction breakdown can be caused to occur at either C 1  or C 2  so that light emission can be selectively obtained at either side of the contact 28 where the junction meets the surface of the device at 20. The device includes an isolating PN junction 22, and in order that the region 34 between the two junctions should exhibit an appropriate resistance to lateral current the distance between the junctions should be between 20 and 200 microinches and the dopant concentration should lie in the range 10<SP>15</SP> to 10<SP>17</SP> atoms/c.c. The lateral current may be further adjusted by applying a suitable reverse bias to the junction 22 via a contact 30 to extend the depletion layer into the region 34 and reduce the effective width of the region. The device may include a larger number of contacts to the region 14 and more than one light-emitting junction. Various arrangements are described suitable for alphanumeric display. A method of making a device consisting of a silicon wafer doped with Sb, P and B using conventional techniques is also described.

The reaction may take place in an aqueous medium which can optionally contain a water-miscible solvent, for example a lower alcohol.  The temperature is preferably in the range 50-150 DEG  C. The free biguanide can be obtained by the action of an alkali, such as sodium or potassium hydroxide.  Salts are formed by treating the free biguanide with an inorganic acid, e.g. hydrochloric or sulphuric, or an organic acid such as acetic, oxalic or picric acid, or with an alkyl halide to form a quaternary halide.

The composition may be in the form of a suspension or emulsion, preferably aqueous, or a solid. Preferred ingredients are biguanides which have the general formula <FORM:0996706/A5-A6/1> and their salts, where either (a) R is an aliphatic group having at least 2 carbon atoms and the aliphatic-oxyphenyl group contains a halogen atom or (b) no such halogen atom is present and R is a hydrocarbon substituent containing from 5 to 9 carbon atoms, and in either case the phenyl nucleus can be further substituted.  The compositions can be used to protect a variety of materials including cloth, leather and agricultural products.
