Patent DE-1921829-A1 (DE)
Inventor: BOURAT GUY
IPC: C08L25/18
Filed: 1969-04-29
Abstract: 1,220,776. Cation exchange membranes. RHONE - POULENC S.A. 29 April, 1969 [29 April, 1968], No. 21897/69. Heading C3P. [Also in Division B1] A cation exchange membrane made of a homogeneous mixture of (a) a poly-p-vinylphenol, which is optionally halogenated, and which is cross-linked via the oxygen atoms of its hydroxyl groups and substituted by cation exchange radicals, and (b) an inert polymer may be prepared by forming a layer of a solution in and organic solvent of the inert polymer and the poly-p-vinylphenol and then, either successively or simultaneously, evaporating the solvent, cross-linking the poly-p-vinylphenol by reaction with its hydroxyl groups and introducing the cation exchange radicals. The inert polymer is one which does not interfere with the cross-linking of the poly-p-vinylphenol or the introducton of cation-exchange radicals and in particular is inert to halogenated compounds and sultones. Suitable polymers are polyvinyl chloride and a copolymer of vinyl chloride with vinylidene chloride or vinyl acetate. Cross-linking may be effected by dehydration in an inert medium containing hexamethylphosphotriamide or dioxane or by treatment of the salt of the polymer with a compound containing at least two reactive halogen atoms e.g. o- or p-xylylene dihalide or 3,3 - bis(halogeno - methyl) - oxetane. Crosslinking and radical introduction may be effected by reaction with a polysultone e.g. spirobi-2: 2 1 - propanesultone. Exchange radicals may be introduced by sulphonation with e.g. sulphuric acid, oleum, chlorosulphonic acid or a monosultone e.g. propanesultone. The membrane may also contain a quaternary ammonium salt and a hexaalkyl phosphotriamide. In the examples are also used poly(4 - hydroxy - 3 - chlorostyrene), poly(4 - hydroxy - 3 - bromostyrene), methyltrilaurylammonium chloride and tributyl orthophosphate.

Abstract: 1,221,759. Moulding pipes. HYDROTILE MACHINERY CO. 20 Nov., 1969 [22 July, 1969], No. 56935/69. Heading B5A. A vertical pipe casting machine in which a rotary packer head 28 is drawn upwardly and axially through a mould 13 whereby concrete fed on to the head by a conveyer 19 is spread radially by vanes 33 and formed into a pipe includes means to control the concrete feed to maintain the level of concrete above the head substantially constant. In Fig. 2 a probe 44 for sensing the concrete level is located in an electrical sensing circuit comprising a control unit 49 and a normally closed limit switch 48. The probe is adjustably attached to a tube 26 attached to the head, and when the concrete contacts the probe the control unit 49 operates to slow or stop the feed conveyer motor 42. The switch 48 is operated to stop the motor when the head reaches the top of the mould. In a modification the conveyer is driven by an hydraulic motor supplied with pressure fluid from a pump via two solenoid operated valves operated by the control unit whereby one or both of the valves are operated depending on the concrete level to stop or slow the conveyer motor. Alternatively instead of a probe the sensing unit comprises an air pressure chamber vented by a valve in response to the concrete level, and an electro-pneumatic transducer signals the control unit in response to the air pressure in the chamber. The sensing unit may comprise an ultra-sonic signal transducer which senses the concrete level with ultra-sonic signals, the control unit being operated by such signals; alternatively the sensing unit comprises a radar unit sensing the concrete level with electromagnetic signals which effect the operation of the control unit.

Title: Remote switching circuit for controlling load - is fitted with reed relay in contactor coil circuit
Inventor: RIESS MANFRED
IPC: H03K17/96
Filed: 1973-07-05
Abstract: Switching of lamps from a remote point involves using electromagnetic switches instead of solid state circuitry such as triacs. The control circuits can be contained in a standard switch housing and comprise a transformer and rectifier to provide a low voltage control supply. The operating button, or proximity switch, is used to actuate the reed relay via a delay element. The operating coil of the contactor is in series with the reed relay. The contactor is located at some convenient point, and may be controlled from several remote switching points. The air path provided by the open contactor adds to safety. Supply failure does not alter the state of the circuit.
