Title: Improvements in and relating to electric cables
Inventor: ENDACOTT JOHN DERRICK
IPC: H01B13/30
Filed: 1965-04-30
Abstract: 1,110,878. Cables. BRITISH INSULATED CALLENDER'S CABLES Ltd. 29 April, 1966 [30 April, 1965], No. 18326/65. Heading H1A. [Also in Division H2] In a high voltage cable, a solid plastics (polyethylene) dielectric which in operation of the cable is subjected to the pressure of a cable gas, is pre-impregnated with the gas. Impregnation may take place before or after sheathing and may be partly or wholly effected after installation of the cable. Impregnation is accelerated by impregnating at a temperature near the maximum working temperature of the dielectric, and at a pressure of one and a half times the working pressure. If the cable has been previously sheathed an equal pressure is applied to the outside of the sheath during impregnation by the use of the gas or another fluid. The impregnation may be effected in a pipe in which the cable is to be installed. Preformed plastics parts for use as dielectric in joints or terminations may also be preimpregnated.

Title: Improvements in and relating to portable drill stands
IPC: B25H1/00
Filed: 1947-07-11
Abstract: 643,869. Drilling-machines. PYE, J. R. July 11, 1947, No. 18408. [Class 83 (iii)] A portable drill stand has a hand-lever for bringing the drill slidably into its working position and control means operatively asociated with a switch such that when the drill is moved into the working position the current to the drill motor is switched on and remains thus until the drill is returned to the non- working position. The drill 15 is carried in arms forming part of a bracket 12 which is slidable on an upright 11 secured to a base 10. A hand lever 16 is pivotally connected at 17 to the bracket 12 and at 19 to a link 20 pivoted to a member 21 secured to the upright. A compression spring 22 is interposed between the top of the bracket and the member 21 for raising the drill when pressure on the lever is released. A further lever 25 is pivoted to a bracket secured to the member 21 and is held in an extended position by means of a spring 26 and turnbuckle 28. On downward feed of the drill an adjustable projection 30 on the lever 25 contacts the switch or trigger 23 of the drill and as the latter approaches the work the switch is actuated to commence rotation of the drill. In an alternative arrangement the switch for the motor is fixedly located on the upright and is moved to "on" and "off" positions by a pair of tension springs one of which is connected to the drill.
Patent GB-596095-A (GB)
Title: A process for the manufacture of ª‡, ª‰-(p, p-dihydroxy-diphenyl)-ª‡, ª‰-di-lower alkyl-ethylenes and of ª‡, ª‰-(p, p-dihydroxy-diphenyl)-ª‡, ª‰-di-lower alkyl-ethanes
IPC: C07C45/52
Filed: 1945-07-18
Abstract: a  : b  - (p : p1 - Dihydroxydiphenyl) - a  : b  - di - lower alkyl ethylenes are obtained by converting a p-hydroxy-phenyl-lower alkyl ketone by treating with sodium amalgam in alkaline medium into the corresponding pinacol, treating the pinacol with a dehydrating agent to obtain the corresponding pinacoline, treating this latter with an alkali metal and an alcohol to obtain the corresponding pinacoline alcohol and reacting the pinacoline alcohol with a dehydrating agent, particularly a mineral acid.  a  : b  - (p : p1 - Dihydroxydiphenyl) - a  : b  - di - lower alkyl ethanes are obtained (a) by hydrogenating the corresponding ethylenic compound obtained as above; (b) by converting a p-hydroxy-phenyl-lower alkyl ketone as above into the pinacoline alcohol, and treating this with hydrogen iodide, advantageously in conjunction with red phosphorus.  In all cases, the expression "lower alkyl" represents an alkyl group containing not more than five carbon atoms.  Suitable agents for dehydrating the pinacoline alcohols are halogen hydracids, especially hydrogen chloride or bromide.  Both the saturated and unsaturated products are oestrogenic.  In examples: (1) p-hydroxypropiophenone, in aqueous caustic soda, is shaken with sodium amalgam and the free pinacol, obtained by adding glacial acetic acid, is treated, in ether, with gaseous hydrogen chloride, the resulting pinacoline being reduced to the corresponding pinacoline alcohol by sodium and alcohol, prior to saturation, in ether, with hydrogen chloride to obtain a  : b -(p : p1 - dihydroxydiphenyl) - a  : b  - diethyl - ethylene; (2) the pinacoline alcohol of (1) is heated in glacial acetic acid with hydriodic acid and red phosphorus to obtain a  : b -(p : p1-dihydroxydiphenyl) - a  : b  - diethylethane; (3) the product of (1) is reduced with hydrogen iodide and red phosphorus in glacial acetic acid to obtain the product of (2).

A process for preserving food articles by cleansing and coating them comprises submerging the food articles in a coating composition comprising a plastic edible normally solid film forming material heated to above its melting temperature, agitating the food article while submerged, removing the excess coating composition from the article while the coating is in a fluid condition and cooling the coated articles to room temperature. Preferably the coating composition is an acetylated monoglyceride derived from hydrogenated lard and contains small amounts of citric acid and the antioxidants BHA and BHT, but hydrogenated coconut oil, confectioners coating butter (a blend of hydrogenated vegetable oils), rearranged animal and/or hydrogenated vegetable oils, and solid plasticized beef shortening are also specified. The coating compositioin is preferably heated to a temperature sufficient to sterilize the surface of the food or the food article may first be cleansed and sterilized by dipping in a heated liquid cleansing medium prior to coating. This cleansing medium may have the same composition as the coating composition or it may be a non-polar low molecular weight organic solvent. In the examples various raw and roasted nuts are coated. Other foods specified include vegetables, condiments, meats, fowl, sea food, cereal grain and dried fruit. Raisins, prunes, figs, dried apricots and dates are specifically mentioned.
Patent GB-166141-A (GB)
Title: Journal box
IPC: B61F15/16
Filed: 1921-07-08
Abstract: 166,141. Lotte, L., (Assignee of Compagnie GÚnÚrale Parisienne des Tramways Soc. Anon.). July 10, 1920, [Convention date]. No Patent granted (Sealing fee not paid). Ball and rolling-friction bearings for axle-boxes of railway or tramway vehicles. The box rests on the axle 8 through the medium of two rings 7 which are mounted in 'ball bearings and are of considerably larger diameter than the axle 8, so that only line contact with the axle takes place. When the wheel encounters an obstacle, the axlebox moves forward relatively to the axle, and prevents sudden shocks. The bearings permit a swinging movement, in order that the axle may assume the oblique position necessitated by the relative movement. Since the movement of the axle in the plane of the outer ring 7 is greater than that in the plane of the inner ring 7, the axle is made conical between the two bearings so as to give an equal distribution of load when using identical ball bearings. If the axle is made cylindrical, the internal diameters of the two rings 7 are made different. The box is closed by covers 3, 4, and is provided with vertical recesses for mounting on the vehicle frame. Vertical reactions are absorbed by springs 10 secured to the vehicle frame.

Title: Improvements in or relating to latches
Inventor: ORDIDGE EDWARD FRANK
IPC: E05C1/16
Filed: 1967-04-22
Abstract: 1,221,653. Latch fastenings. JOSIAH PARKES & SONS Ltd. 16 April, 1968 [22 April, 1967], No. 18659/67. Heading E2A. A combination comprises a slidable-bolt, mortice latch in which the latch bolt head 16 has a pair of parallel side faces 30 and at least one face 31 at its outer end which is rounded or V-shaped, each side face having at least one rib 33 which projects from the side face and extends generally parallel to the direction of shoot of the 'bolt, each rib terminating at its outer end in a bevelled face 34 which forms a continuation of said outer end face or of one of said outer end faces if there are more than one and a striker plate 44 having a bolt hole 46 to receive said head and a bevelled lip 45 to engage said head, the side of the bolt hole adjacent the lip being recessed to receive the or each rib on the side face of the head adjacent to said side. In the construction shown in Fig. 1 the bolt head has a single rounded outer end face which extends the whole distance 'between upper and lower faces of the head and each side face has one rib only. Fig. 4 shows a bolt head in which the outer end face 55 is V-shaped and extends only for part of the distance between the upper and lower faces of the bolt head, the head having secondary end faces 58 which are stepped back from the primary end face; both heads can however have either a round end face or a V-shaped end face and can be modified to have two ribs on each side instead of one. In the case of Fig. 4 when there are two ribs on each side there will be two primary end faces. The striker plate shows an addition to the recess 48 to receive the rib in the lip side of the plate has a second recess 48 to the rib at the opposite side of the bolt head. In addition to the recesses 48 the striker plate has tabs 49 which extend rearwardly and which engage one side face of the bolt head. The striker plate shown is for use with a latch which is also fitted with a dead bolt and it has two holes one for the dead bolt and one for the latch bolt the striker being reversible for left or right hand doors. The bolt heads being symmetrical about their centre line are suitable for right and left hand doors without any modification being necessary to the latch. The provision of the ribs is stated to provide a good compromise between a long enough abutment surface of the bolt head to cater for comparatively large clearances between the forend of the latch and the striker plate when the latch is installed and also give an adequate bolt surface to ensure that the bolt retracts when the door is slammed since the bevelled surface in effect overlaps the abutment surface due to the bevelled surface being continued on the outer ends of the ribs.

An intermittent metal strip feed comprises a pair of rollers adapted to be driven by a reversible electromotor controlled by switches actuated by a reciprocable member which is driven forward by the strip and returns independently. Strip from a coil 2 passes between vertical guide rolls 6, and through straightening rolls 7 to a pair of serrated rolls 8 which are driven by a reversible motor 9 through a freewheel. The strip then passes over a carriage 10 which reciprocates on guide rails 13 and which supports a fixed lower jaw 11 and a pneumatically or hydraulically controlled movable upper jaw 12. The carriage actuates limit switches 16 and 17 which reverse the electric motor 9 and cause the jaw 12 to grip or release the strip as required. Beyond the carriage track are further guide rollers 14 and a pair of rollers 15 which apply lubricant to the strip. Operation.-When the machine is started the motor 9 drives the rollers 8 which feed the strip and the jaw 12 clamps the strip so that the carriage 10 moves with the strip until the limit switch 16 reverses the motor and simultaneously releases the clamp 12. Due to the freewheel device, the motor armature is free to reverse and the carriage stops immediately. The feed of the strip is determined by the travel of the carriage, which is returned by springs or weights.
