Title: Improvements relating to a process for the chlorination of hydrocarbons
IPC: C07C17/156
Filed: 1962-03-20
Abstract: Olefines are chlorinated to 1,2-dichlorinated hydrocarbons by contacting a mixture of olefine, oxygen-containing gas and gaseous HCl with a fluidised bed of cupric chloride deposited on an active alumina support, the catalyst being disposed in a reactor in the shape of an inverted truncated cone, the upper periphery of which is connected to a cylindrical vessel, the apex of the cone having an angle of 5-15 degrees, the ratio of the larger to the smaller diameter of the cone being from 2:1 to 3:1, and the length of the cylindrical vessel being approximately one-fifth of the length of the truncated cone; the catalyst being employed in such amount that in the nonfluidised condition it fills approximately three-quarters of volume of the truncated cone and when fluidised it fills the cone substantially completely.  An example prepares ethylene dichloride from ethylene. Specification 955,751 is referred to.

Title: Improvements in jacquard card feeding mechanism for looms
IPC: D03D39/00
Filed: 1929-04-08
Abstract: 326,681. Liebender, G. April 8, 1929. Jacquards.-In looms for weaving chenille material in which the weft threads are selected by jacquard mechanism, provision is made for interrupting the feed of the card cylinder to allow a desired number of picks of the same colour to be inserted into the cloth. The pawl and ratchet mechanism which operates the cylinder is supplemented by an additional pawl 11 which controls and reciprocates with the feeding pawl 5, while it is axially displaceable relatively thereto, the nose of the pawl being capable of engagement with any one of a series of rotatable co-axial guide wheels 10<a> - - f, lobsely mounted on the shaft 1. The guide wheels are provided with ratchet teeth 20 and notches 21 which, on being swept by the pawl 11, allow sufficient pawl deflection for maintaining the feeding pawl, either in or out of operative position. The pawl 11 is mounted on a bar 12 which is reciprocated from a rock shaft 16 and is propelled across the surface of the guide wheels by a swinging arm 22 whilst a bell-crank 26 operated by jacquard mechanism comes into the path of a lug 27 of the bar 12 on its return movement to stop the pawl opposite the desired guide wheel. The spacing of the deep notches is regular in each particular wheel but differs from that of the other wheels so that the number of successive weft threads of the same colour can be varied by a suitable selection of wheels.

Liquid instead of, or in addition to, air may be admitted to the part e by a pipe l. The admission and exhaust of compressed air is controlled by a valve m operated by an electric motor n. In another form, a pipe is suspended centrally in the chamber d and is filled with water entering with the material. When compressed air is admitted to the upper part of the vessel, this water is forced down and loosens and drives the material towards the delivery pipe. Additional air or water, or both, may be introduced into the base or side of the vessel, or into the delivery pipe, to assist the compressed air introduced at the top. In another form, a number of air-pipes pass down into the vessel d so that compressed air or liquid admitted to them loosens the surrounding material, while a jet brought in at the base under the lower end of the delivery pipe forces the material up the pipe. Air is also admitted above the material and may be admitted to the delivery pipe. The lower part of the delivery pipe may be in the vessel d, and may have a hole for the exhaust of air during the filling of the vessel, and also for the admission of compressed air to the pipe during delivery.

Title: Improvements in float operated valves for use in steam traps and like purposes
IPC: F16T1/26
Filed: 1942-08-08
Abstract: 558,240. Steam traps. CARTER, F. S. Aug. 8, 1942, No. 11139. [Classes 64 (ii) and 123 (iii)] A float or bucket e is suspended from a discharge valve a by a wire or rod c, the valve being kept closed by the weight of the float acting against the fluid pressure. Decrease in weight of the float due to a rise in level of condensate allows the valve a to open under fluid pressure. A reducing valve in the inlet i<1> allows the trap to be used on higher pressures. In a modification, two inlets may be used diametrically opposite one another, at a level above the float so that the apparatus may be used as a liquid separator in a compressed air line. In another modification for lower pressures, the weight of the float may be partly balanced by a spring surrounding a rod extending upward from the valve a.

Title: Drive mechanisms for vehicle windscreen wipers
IPC: B23K37/00
Filed: 1972-03-10
Abstract: 1312428 Windscreen wipers ROBERT BOSCH GmbH 10 March 1972 [13 March 1971] 11206/72 Heading A4F [Also in Division H2] A parking device included in a drive mechanism for windscreen wipers comprises a permanent magnet whose circular path, when mounted on a worn gear driven by motor 10, leads past a magnetic field dependent resistor 38. Maximum magnetic field at the resistor 38 occurs when the wipers which are driven by the motor 10, are in their parked position. Closing of a manual switch 21 actuates the motor 10 via a switch 23 in a relay 20. As the magnet moves away from the resistor 38 the resistance of the resistor 38 decreases causing a transistor 34 to become non-conductive and a second transistor 31 to become conductive thereby by passing the manual switch 21 since the line containing elements 26, 24, 32, 31 and 33 is continuous. On manually opening the switch 21, the motor 10 continues to operate by virtue of the by-passing through transistor 31 until the magnet 40 again increases the resistance of the resistor 38, i.e. when the wipers are in their parked position. The transistor 34 then becomes conductive thereby causing the transistor 31 to become non-conductive and hence de-activating the relay 20 causing the motor 10 to stop.
Patent GB-309504-A (GB)
IPC: G03C7/04
Filed: 1929-04-11
Abstract: 309,504. Nordmann, C. April 11, 1928, [Convention date]. Colour filters.-The colours for a multicolour filter for colour photography or cinematography are ascertained by projecting a light beam from a source of white light, such as an electric arc, on to a screen after passing through a multicolour filter having coloured bands approximately in accordance with the normal spectrum of white light. The spectrum of the light source is projected on to the screen adjacent the first image and by successive trials of different dyes and varying quantities of the same dye the colour bands on the filter are adjusted until the eye sensations produced by the filter image are identical with those produced by the spectrum. When the colours and their intensities have thus been ascertained the colour bands may be interchanged on the filter or given any shape desirable. The filter may be used with sensitive layers covered with goffered elements.

A method of making a hollow metal body such as a shell, preferably having cylindrical and conical portions, comprises heating a metal billet to extrusion temperature, coating at least the external surface and lower part of the billet with a first vitreous lubricant having a low viscosity at the surface temperature of the billet, placing the billet 3, Fig. 4 (not shown), in a die 1, slightly compressing the billet in the die, Fig. 5 (not shown), placing in the centre of the upper part of the billet a small quantity of a second vitreous lubricant 6, Fig. 6, having a higher viscosity than the first lubricant, rapidly piercing the billet with a punch 2, Fig. 8, whose lower face has a recess 2e adapted to retain a certain quantity of the second vitreous lubricant, the metal of the billet being thereby forced down to the bottom of the die and also extruded upwardly along the wall of the die and punch, and ejecting the hollow body by means of an ejector 7. The billet is first heated to a temperature of about 1200‹ C. in. a coal furnace, gas or oil furnace, electric furnace or an induction furnace, the heating being effected without any special precautions to avoid oxidation. After withdrawal from the furnace the surface oxide on the billet may be removed by jets of water under pressure. The first viscous lubricant may be glass powder or enamel having a viscosity between 50 and 500 poises and is applied by depositing the powder on an asbestos sheet over which the billet rolls on its discharge from the furnace. The second viscous lubricant preferably comprises powder glass 6, Fig. 6, having a viscosity between 500 and 1000 poises and is applied through a funnel 5, Fig. 6. The extruded body may be subsequently machined. A specific example is given for the pressing of a 120 mm. calibre shell giving the dimensions of the punch and die, the dimensions of the billet, and the composition of the vitreous lubricants used. Specifications 716,933 and 731,321 are referred to.
