Title: Improvements in or relating to non-explosive capacitors
Inventor: FIALKOWSKI HEINZ
IPC: H01G2/14
Filed: 1965-08-12
Abstract: 1,072,087. Capacitors. SIEMENS A.G. Aug. 12, 1965, No. 34492/65. Heading H1M. Capacitor casing 13 is crimped over end plate 11 as shown at 14 so that the force exerted on the end plate when excess pressure develops within the casing is transmitted to the crimped end adjacent to the casing wall. The end plate thereby moves, because of corrugations 12 to rupture a tear-out protector (not shown) and the current supply is cut off. In previous designs, illustrated by Fig. 1 (not shown), the force tended to unfold the crimped edge. The end plate may further be provided with e.g. recesses on its interior faces which cooperate with notches or depressions in the casing wall to secure the end-plate independently of the crimped edges, and also to prevent rotational movement.

Filed: 1968-07-20
Abstract: 1,218,785. Sowing machine. S. MOORE. 14 July, 1969 [20 July, 1968], No. 34711/68. Heading A1D. An agricultural sowing machine comprises a frame 13 for mounting arm assemblies 36 which carry soil cutting discs 42, these being resilient means 50, 55 urging the arm assemblies away from the frame, and a resilient connection 29 between the frame and a member 11 connected to the frame, the adjustment of which connection alters the loading applied to the discs 42. Each arm assembly comprises pairs of arm 37 and 38. Each arm 38 carries a depth control roller 41 whose vertical position may be varied, and a pair of inclined soil cutting discs 42. A rod 52 pivotally connected to each arm assembly 36 passes through a member 54 and is surrounded by compression springs 55 and 56 whose loading is controlled by an abutment member 57. If a depth control roller 41 or cutting disc 42 encounters an obstruction, the corresponding arm assembly 36 will lift due to the yield of spring 55. A rod 24 engages members 11 and 13 at trunnion blocks 26 and 20, and is surrounded by compression springs 29 and 30, and rotation of handle 32 alters the effective length of the rod between trunnion blocks 20 and 26, thus ensuring that there is adequate weight on the discs 42 to provide adequate soil penetration, whilst maintaining adequate weight on ground compacting rollers 44. Seed is delivered through a tube (90), Fig. 4 (not shown), located adjacent to each disc 42 from a box 70 whose delivery is controlled by a seed metering device driven by the action of the spider wheel 74. A skim (94), Fig. 3 (not shown), prevents vegetation from gaining access to and blocking the seed tube.

Abstract: 1487913 Cationic oligourethanes BAYER AG 20 Aug 1976 [23 Aug 1975] 34779/76 Heading C3R [Also in Division D2] A cationic sizing agent for paper comprises a solution in water or in a mixture of water and a water miscible organic solvent, e.g. an alcohol, of an oligourethane Mol. Wt. 500 to 5000 having protonated and/or quarternized ammonium groups. The oligourethanes may be obtained by reacting a polyioscyanate, e.g. diphenyl methane 4,4<SP>1</SP> diisocyanate or the mixed phosgenation products of aniline/formaldehyde (technical MDI), with a polyalkanol, particularly an N-alkyl diethanolamine having a total of from 5 to 12 carbon atoms and optionally with a chain terminator, e.g. N,N- dimethylamino ethanol in a solvent, e.g. isopropanol. The amino-nitrogen atoms of the oligourethane are at least partially protonated and/or quaternized by reaction with an acid and/or a quaternizing agent during or subsequent to the polyisocyanate/polyalkanolamine reaction. Suitable polyalkanolamines are N- methyl, N-ethyl, N-cyclohexyl and N-benzyl diethanolamines, triethanolamine and tetrapropoxylated ethylene diamines. The required cationic groups may also be provided before the polyisocyanate/alkanolamine reaction by using quaternized or protonated derivatives of the polyalkanolamines. Suitable quaternizing agents are epichlorohydrin, methyl sulphate and benzyl chloride and suitable protonating agents are formic and acetic acids. The mainly organic solution of the protonated and/or quaternized oligourethane obtained on completion of the reaction is diluted with water or aqueous acids, e.g. formic and acetic to give solutions having solids contents of 5 to 57% by weight which can be stored and transported in this concentrated form and from which the ready to use sizing agent may be obtained by further dilution with water to give solutions having a 0À02 to 10% by weight solids content. The sizing agents may be used to size a wide range of papers including those containing acidic neutral or basic filling materials, e.g. chalk, talc or casein. They may be applied by mixing with the paper pulp, by subsequent immersion or spraying of the sheet and by coating on to the surface of the paper using a glue press.
