Abstract: A paper-coating composition comprises an aqueous dispersion or emulsion containing, on a dry solids basis, from 15 to 75% by weight of a non-oxidized polyethylene, from 15 to 55% of an elastomeric polymer in the form of a butadiene-styrene copolymer or an acrylic polymer, and a tackifying resin.  The elastomeric component may contain 0.5 to 7% of an unsaturated carboxylic acid e.g. (meth)acrylic acid or itaconic acid.  Specified acrylic polymers are those of ethyl (meth)acrylate, methyl methacrylate, butyl acrylate and propyl acrylate.  The tackifier is e.g. a glycerol ester of polymerized rosin (a), dammar gum, hydrogenated rosin, manila gum or a coumarone-indene resin.  In the examples polyethylene emulsions are mixed with (1) a carboxy-styrene-butadiene copolymer emulsion and tackifier (a); (2) to (5) a butadiene-styrene copolymer and tackifier (a); and (6) a styrene-butadiene-itaconic acid copolymer latex and tackifier (a).  The coatings are applied to kraft paper boards (see Division B2).ALSO:A heat sealable coated paper comprises a paper substrate and a coating containing 15 to 75% by weight, on a dry solids basis, of a non-oxidised polyethylene, 15 to 55% of an elastomeric styrene-butadiene copolymer or acrylic polymer and a tackifying resin.

Abstract: 989,000. Dish washing machines. WASTE KING CORPORATION. Nov. 27, 1963 [Nov. 27, 1962], No. 46881/63. Heading A4F. In a dishwasher for washing, rinsing and drying dishes the operating cycle of which is controlled by a timer, heating means 24 is provided comprising a low-output heating element 36 operable for all or a major portion of the operating cycle and a highoutput heating element 38 operable for at least one period in the operating cycle. In operation the timer controls the operating cycle of the dishwasher such that it energizes heating element 36 when the dishwasher is switched on and it energizes the heating element 38 only when the water for the main washing and rinsing operations is introduced into the tub 12 of the dishwasher. When the heating element 38 is energized the timer is itself switched off until the water in the tub 12 reaches a predetermined temperature, e.g. 200F., determined by a thermostat 40. The timer is then re-energized and it switches off the heating element 38. The thermostat 40 only operates to affect the timer when the heating element 38 is in operation. In the example shown the heating elements 36 and 38 are electric resistance heaters sheathed and embedded in insulating material. In a further example the heating elements are sheathed separately.
Patent GB-469849-A (GB)
Abstract: 469,849. Current, pressure, and power meters. LINCOLN, P. M. May 8, 1936, No. 13059. [Class 37] [Also in Group XIX] A thermal electric meter comprises electric heating elements influencing temperaturesensitive devices mechanically connected to an angularly-movable driving member coupled by pin-and-slot means to a pointer-operating member, the pin being adjustable in the slot when the members are in their zero position without moving the members, this adjustment altering the transmission ratio between them at other parts of the scale. The principle of the invention is shown in Fig. 2, in which the driving member 9 is pivoted at O<1> and the pointer or pointer-operating member 10 is pivoted at O. The pin 16 engages a slot 19 in the driving member 9 and is carried on a block 14 slidable along the pointer member 10 and arranged to be secured in any set position. In modifications, (a) the pin 16 may be secured to the driving member and the axis of this member may be movable along the line 001, and (b) the slots in the members may be curved to preserve a constant velocity ratio between the members over the deflection range. In the embodiment shown in Figs. 7 and 8 the heating elements 33 are positioned adjacent fluid chambers 32 each connected to a Bourdon tube 3<1>, 41. The lower ends of the tubes are connected to arms 25, 26 by screws 27, 28 which are used to adjust the pointer 29 to the zero position. The tubes are secured at the top to an arm 22 on a shaft 2 carrying the driving member 9 connected by the pin-andslot 16 to the pointer-operating member 10<x> which is fixed to the shaft 251 of a quadrant 26<1> geared to the pointer 29.

Abstract: 1281777 Semi-conductor devices HUGHES AIRCRAFT CO 9 Oct 1970 [24 Oct 1969] 48096/70 Heading H1K A tetrode IGFET comprises a first gate electrode extending from the source region partially over the channel region and a second gate electrode extending over part of the first gate electrode and over other portions of the channel from which it is insulated by a layer of material having a low electron trap density. This insulating material may be thermally grown silicon oxide as opposed to pyrolytically deposited silicon oxide or nitride. As shown, Fig. 1, a P-type Si layer is thermally oxidized to provide a masking layer for the diffusion of P or As to form N-type annular source region 12 and drain region 14. Oxygen is introduced near the end of the diffusion process to reform the masking layer and an annular window is opened to expose part of the channel region adjacent to the edge of the source region. A thin layer 4 of oxide is thermally grown and may be covered with a thin layer 5 of silicon nitride by pyrolytic decomposition of silane and ammonia. A layer of polycrystalline Si is deposited by pyrolysis, electron beam evaporation or sputtering and is degenerately doped with B and etched to form the first gate electrode 6. A thermally grown oxide layer may be used as a mask for the etching of the Si gate electrode. The silicon oxide and nitride layers covering the surface, other than layers 4 and 5, are removed and the whole surface is thermally oxidized, the oxide layer 4<SP>1</SP> extending over the first gate electrode 6 since this is also of silicon. Windows are etched and Al, Cr or Au is deposited to form source electrode 12<SP>1</SP>, drain electrode 14<SP>1</SP>, and a contact (not shown) to a tab extending from the first gate region 6. A layer of Al is then deposited and masked and etched to form a second gate electrode 16 which extends over the whole of the channel region. The second gate electrode need not overlap the first gate electrode or may overlie only part of the channel region not covered by the first gate electrode. The first gate electrode may be of metal instead of silicon.

[Also in Division C7] A silver base alloy for making electrical contacts consists of CdO 1À0-20À0% by weight K or Ca 0À001-0À25% by weight and the balance Ag apart from any incidental impurities. In making the alloy, Cd, Ag and either K or Ca in quantities such as to produce the alloy are melted together and the melt solidified and subsequently heated in an oxygen containing atmosphere to oxidize the Cd to CdO. The solidified melt may be formed into electrical contacts prior to or after the oxidation step. E.g. molten Cd-Ag-K may be poured to form an ingot, the ingot be reduced by rolling or drawing, and the stock so formed be heated for one to several hours in an oxygen bearing atmosphere at 1500‹ F. to oxidize the Cd. The Cd then takes the form of CdO particles dispersed throughout a Ag matrix containing K. Fig. 2 (not shown) illustrates a stud contact. Fig. 3 shows a contact assembly 15 comprising strips 7 of the alloy, layers 9 of fine Ag, solder layers 11 and a base metal strip 13, e.g. of brass, Be-Cu or phosphor bronze.
