Title: Electrical wiring arrangement
Inventor: PRIOR HECTOR THOMAS
IPC: H05K7/12
Filed: 1970-04-07
Abstract: 1,249,752. Wiring guide. INTERNATIONAL STANDARD ELECTRIC CORP. 7 April, 1970 No, 16399/70. Heading H2C. A wiring guide 1 made of resilient metal or plastics is mounted on an electrical equipment rack 2 and has holes formed in an upstanding strip of the guide for receiving wires 3. These wires are led in by a tool 5 and when it is necessary for this tool to move at right-angles to the upstanding strip it is pushed through one of a number of slits 4 which are formed in the upstanding strip one at the side of each hole. The two edges of the respective slit are forced apart by the tool 5 and then spring back with their own resilience.

Abstract: 480,247. Lapping or burnishing gears. BROWN & SONS (HUDDERSFIELD), Ltd., D., and MERRITT, H. E. June 13, 1936, No. 16540. [Class 60] [Also in Group <I> XXII] In a method of finishing the teeth of helical spur, or worm gears a finishing tool a having teeth conjugate to those of the work b but of different helical angle is arranged on an axis a<1> inclined to the work axis b<1>, the tool gear being mounted in a slide d which is reciprocated in adjustably inclined guides d<1> which are not parallel to either tool or work axes. In a modification, Fig. 2, the tool spindle slide d is reciprocated in guides c. These motions are equivalent as shown in Fig. 3, to traversing the gear b on its axis and traversing the tool in a direction c<1> perpendicular to the tool axis. If the tool acts as a shaving tool it may be reciprocated one or more times across the work while it makes one traverse in the direction c<1> or it may be reciprocated in direction c<1> while it traverses the face of the work. Either of these cycles may be repeated to take successive shaving cuts. A higher speed may be used for lapping or burnishing. The tool gear teeth may have straight or inclined cutting edges to take shaving cuts or they may be smooth to provide a burnishing action or when supplied with abrasive to give a lapping action. Either tool or work may be driven and to provide pressure between tool and work either the non-driven member may be braked or the work and tool may have relative approach feed movement.

Title: Improvements in or relating to impingement-type separators for the removal of finelydivided matter from a gas stream
IPC: B01D45/08
Filed: 1958-05-23
Abstract: 852,163. Separating liquid particles from gases. UNION CARBIDE CORPORATION. May 23, 1958 [May 24, 1957], No. 16582/58. Class 123(3) [Also in Group XXVIII] A separator for removing finely divided liquid droplets or dust particles from a gas stream consists of a cylindrical casing 12 across which is mounted a series of staggered row of struts 13 of substantially streamlined tear-drop cross-sectional shape as shown in Fig. 3. The casing is preferably substantially vertically positioned with the inlet 11 at the top and the outlet 15 at the bottom. The finely divided matter impinges on the struts and passes therefrom into a collector chamber 14 whence it is removed through conducts 16. To secure the struts firmly to prevent rattling in use whilst allowing them to be removed easily for cleaning they are held in position by a series of retainer rings 17, each ring having edge slots which co-operate with those on the adjacent rings, Fig. 3, to define openings into which fit the ends of a row of struts. The assembly is mounted between standard flanges and held together by rods extending therebetween. When the carrier gas is acidic the casing, struts and retainer rings are made of an inert substance such as resin impregnated graphite. For large diameter casings wherein excesive strut length would cause re-entrainment, short struts are assembled into units having separate drain chambers and the units are arranged to fill the casing.

Title: Improvements in and relating to methods of removing cations from liquid media
IPC: B01D15/04
Filed: 1943-10-13
Abstract: Liquid media, e.g. water, are purified from cation-containing constituents by passing the media through a granular mass of an insoluble infusible resinous product obtained by reacting a phenol, an aldehyde, and a semi-amide of a polycarboxylic acid, e.g. maleamic, oxamic, or phthalamic acid, the semiamide being present in the proportions of 0.25-0.8 mols. per mol. of phenol.

Abstract: 220,420. Sykes, A. F. June 28, 1023. Addition to 160,223. Thermionic amplifiers. - An electromagnetic sound transmitter or receiver similar to that described in the parent Specification may operate a loud speaker, or scund-recording apparatus, or may control a broadcasting station, through the valve circuits shown in Fig. 6, which permit selective amplification of the low or high notes. The potentials induced in the detector or transmitter are applied to the grid of valve 37, the plate circuit of which includes a resistance 189 and the primary 43 of a transformer, the secondary being connected to the grid of valve 42 and, at will, to the point 190 or 191. A resistance 193 in the plate circuit of valve 42 is adjustably shunted by a condenser 194. The plate circuit of valve 46 is connected by transformer 45, 54 to a power valve 47. Valve 37 amplifies uniformly the lower harmonics but increase or diminishes the higher harmonics according to the transformer connections. Valve 42 amplifies the bass notes more than the treble, while valve 46 increases the value of the harmonics in direct proportion to their frequency. A condenser or inductance mav also be connected across part of the resistance 189. Specification 186,658 also is referred to.

Title: Improvements in Search Lights and in Luminous Sources.

Filed: 1918-10-18
Abstract: 120,568. Reache, L. G. Gerville-, and Pineau, J. L. T. Oct, 18, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Search-lights.-A searchlight apparatus stated to be applicable for searching for passing aircraft consists of a reflector in the form of surfaces of revolution, such as a paraboloid or a series of truncated cones, and an intense source of light of large diameter, produced for instance by the combustion of magnesium, calcium silicide, or an alumino-thermal or other composition. Provision is made for maintaining the luminous source at a constant level as the composition is consumed, for rotating it rapidly so as to eliminate slag, and for preventing the deposit of burning particles &c. on the reflector. The luminous source may be intermittent and may change in colour. The burning particles, smoke, &c. may be withdrawn by a blower and an air exhauster, which may be supplemented by a revolving grating or fan for cooling purposes, or alternatively a jet or sheet of water may be projected between the focus and the reflector. In the form shown in Fig. 1, the reflector is constituted by three assembled truncated cones 1, 1<1>, 1<11>, and the luminous source consists of a pot 2 containing the combustible composition. In a second form, a sheet of water is poured from a slit conduit over the inner surface of the reflector to protect it from the burning particles. Instead of employing an illuminating pot, the composition may be used in a pulverulent form, delivered from a container in front of a blowpipe or like nozzle which projects it in the form of a cloud. If desired, as in the case when the constituents of the composition are innocuous singly but when combined form an explosive mixture, the constituents may be delivered separately to the blowpipe.
