Title: Supports for the windscreens of motor cars or the like
IPC: B60J1/00
Filed: 1923-08-30
Abstract: 203,337. Minguet, M. G. A. Aug. 30, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Windscreens.- The windscreen A of a motor or like vehicle is mounted on a telescopic support, the lower part a of which is pivoted at its base b while the upper part c slides s within the lower under the control of a connecting-rod or stay f which, when the support is pivoted about its base, causes a relative movement of the parts a, c giving sufficient lift to the screen to make it move in a substantially horizontal path. In the construction shown in Fig. 2, the rod c is provided at its lower end with pins d which project through slots e in the tube a, while the rod f is pivoted at its ends to the pins d and to a fixed support g. The extreme movements of the support are limited in either direction by the ends of the slots e, and wing-nuts provided on the pins d may clamp the support in any intermediate position. In order to assist the lifting action of the rod f a spring h is preferably located in the tube a. Modifications are described in which the pins d also move in slots in the rod f, and in which the rod f lies substantially horizontally when the support a, c is vertical.

Abstract: 1,154,515. Electron multipliers; image converter tubes. MULLARD Ltd. 12 March, 1968 [15 May, 1967], No. 22339/67. Heading H1D. In a channel intensifier device as described in Specification 1,090,406, the photo-emissive surface areas, in addition to being in contact with the input electrode of the device, are arranged in such manner as to lie across and effectively close the entrances to the channels of the device while being adapted to receive radiation from the side remote from the input electrode and to emit photo-electrons from the side facing the channel entrances. The input electrode may be extended some way into each channel to provide a lens effect or the channels may be tilted. In either event the photo-electrons are directed to the channel walls at an early stage. These two arrangements may be combined. In the figure shown where P is the photo-emissive layer and E1 the input electrode the lenses formed by the penetrating parts of the input electrode are tilted. The parts of the photo-emissive layer P which corresponds to the input electrode E1 may be omitted and in another alternative the photo-emissive layer may constitute the input electrode. The photoemissive layer may be provided on a glass plate which may be the window of the tube. A combined photo-emissive layer and input electrode may be a gold layer, e.g. in an ultra-violet image intensifier. The entrances to the channels may be outwardly flared or tapered.

Title: Glycol carbamates and processes for the manufacture thereof
Inventor: VIARD MARCEL-JEAN
IPC: C07D295/205
Filed: 1950-09-15
Abstract: The invention comprises glycol carbamates in which the N may be substituted by alkyl, aralkyl or aryl, heterocyclic, or may be a member of a heterocyclic ring, or symmetrical glycol carbamates as above but having two N atoms joined by alkyl &c., or in a common heterocyclic ring; these are obtained by the action of ammonia or a primary or secondary mono- or di-amine which may be substituted by alkyl, aryl or aryl alkyl groups, or be heterocyclic, on cyclic carbonates of glycols, obtainable by the action of sodium bicarbonate on chlorhydrins or carbon dioxide on ethylene oxide or its homologues.  In examples, the cyclic carbonate of ethylene glycol is caused to react with ammonia, ethylamine, propylamine, diethylamine, benzylamine, thienylamine, cyclohexylamine, and piperidine, to give the corresponding substituted glycol carbamates, and with ethylene diamine and piperazine hydrate to give the symmetrical dicarbamates derived from one mol. of the amine and 2 of the glycol.  The reaction must take place at a relatively low temperature, generally < 50 DEG C., to avoid the formation of undesired products.

Title: Improvements in or relating to the production of sodium methoxide
IPC: C07C29/70
Filed: 1947-08-20
Abstract: Solid sodium methoxide substantially free from methanol is obtained by heating the sodium methoxide monoalcoholate of methanol to a temperature above 128 DEG  C., but below the charring temperature of sodium methoxide at atmospheric pressure in the absence of air or oxygen.  Sodium methoxide is said to char at about 300 DEG  C. or on prolonged exposure to high temperatures at about 250 DEG  C.  A methanol solution of sodium methoxide may be contacted with a heated metal surface as by passing a charge, which should be equivalent to about one-third of the total capacity of the vessel, into a closed heated vessel provided with agitation means so that the product is obtained in a discrete form or by revolving an internally heated drum therethrough in an enclosed system, the methoxide separating on the drum being removed by means of a doctor blade.  Both these processes are performed in an inert atmosphere by passing through an inert gas, e.g. argon or nitrogen which also serves to remove liberated methanol.  Alternatively, the above solution may be subjected to flash evaporation by contact with a heated inert high boiling liquid, e.g. xylene or decahydronaphthalene.  An example is given of the first of the above processes and drying times of three and four hours are used at temperatures of 170 DEG  and 160 DEG  C. respectively.

Abstract: 1325226 Coating inside hollow objects; spray nozzles NORDSON CORP 19 April 1971 [5 March 1970] 23240/71 Headings B2E B2F and B2L A hollow can body 10 is coated internally by the overlapping spray patterns from two nozzles 12, 13 which nozzles are operated during high speed rotation of the can. As shown in Fig. 2 cans 10 are indexed by a turret 21 to a coating point where they are pressed against a driving roller 22 by means of a pressure roller 24. After coating the cans are allowed to roll down a chute 18 to allow the coating to harden before they enter an oven (not shown) which completes the finishing process. The nozzles, which have apertures o or o' as shown in Figs. 3, 4 respectively, produce spray patterns which spray more coating material to one side of a central axis of the nozzle than is sprayed on the other side of said axis the effect being that when these nozzles are used in combination with an overlapping zone towards the centre of the can body a uniform distribution of coating material along the whole length of the can body is provided. The can is rotated in such a way that the leading edge of the seam moves directly towards the oncoming sprayed material thus ensuring that the seam is completely coated. The centrifugal force of the cans rotation also helps distribution of spray material. The coating materials may be vinyl, epoxy, phenolic, acrylic or alkyd.
