Abstract: 734,779. Power feed for machine tools. GIDDINGS & LEWIS MACHINE TOOL CO. July 4, 1952 [July 24, 1951], No. 16861/52. Class 78 (2). [Also in Group XXII] A multiple power line feed for a machine tool element 35 susceptible of translational movement along a given path, comprises a feed reel 95 carrying a number of feed lines and tensioning means 115 for tensioning the lines. Thus (Fig. 11), in a planing machine, lines X, comprising air hydraulic and cooling water lines, come from fixed connections on the right and are -led around movable reel 95 and pass down movable duct 99 to a headstock. Likewise, electric lines 111-4 are led around movable reel 92 and pass down the same duct to the headstock. The tensioning means is cable 115 which is secured (Fig. 4) resiliently at 116, passes round reel 95 (or 92) then around fixed pulleys 118, 119 (not shown) and then secured at its other end to said duct 99. As the headstock carried by duct 99 is moved along its slide so as to position its cutter head, the reel 95 rolls over its floor and spaces itself from the duct under the influence of cable 115 so that the lines are maintained taut. Lines are similarly led to the ducts 121, 126 (Fig. 4) of other headstocks, and to the head 132 of the movable control panel 69. The lines are contained in housing 70 which stretches over and across the planing machine. The milling cutters are controlled automatically from valves 51, one for each headstock 34, 35, 36, which valves are worked by cams. When the cutter is to work longitudinally, the cams and valve are placed alongside the planing machine, and when the cutter is to work crosswise the cams and valve are placed on the appropriate slide 41 of the headstock, the valve and associate lines being made to fit at will in sockets fixed beside the planing machine or on the said slide.

Abstract: 981,294. Cigarette mouthpieces. BRITISH-AMERICAN TOBACCO CO. Ltd. May 2, 1963 [May 3, 1962], No. 17070/62. Heading A2C. A hollow mouthpiece comprises a strip of corrugated paper 1 adherent at its crests to a flat backing strip 20 and brought to a round cross-section with the backing strip on the outside, the corrugations being formed longitudinally of the material from which the corrugated strip is produced. The strip 1 is first passed between two plates having converging, inter-fitting, corrugations so as to form the initial corrugations in the strip. The flat corrugated strip is then passed between a series of corrugated rollers where the strip 20 is applied. The strip 20 may be provided with a heatsensitive adhesive, heat being applied when the strips 1 and 20 are brought together. The edges 24 of the strips are trimmed and the strips are passed through a former to produce the shape shown in Fig. 6. A further adherent strip 31 is then applied, the ends of which are folded around the strip 20. The assembly is then heated and compressed until the edges of the strip 31 form a butt joint 40. After being cooled the formed tube is cut into suitable mouthpiece lengths. The strips 20 and 31 may be of paper or metal foil, e.g. aluminium foil, and the paper strip 1 may be glassine paper, flocked paper or metallized paper coated with a thin film of metal, e.g. aluminium.

Title: Improvements in speed-responsive switches

Filed: 1936-06-19
Abstract: 480,351. Centrifugal switches. BURGESS, A. F. (Lee Engineering Research Corporation) June 19, 1936, No. 17099. [Class 38 (v)] [Also in Group XIII] In a speed-responsive switch a rotary member 15 carries at its periphery a plurality of pairs of contact-carrying springs 28, 29 connected in parallel or series-parallel and adapted to disengage or engage each other simultaneously or in close succession at a certain speed. The position of the springs 28 is determined by screws 43 in a disc 40 rotatable with the member 15 but axially adjustable in relation thereto by means of a screw 46. The springs 29 with their contacts 33 are acted on by centrifugal force and at a certain speed leave the contacts 32 on the springs 28. In the' form shown there are ten pairs of springs 28, 29 and the current to them is led through brushes 25, 26 engaging slip rings. The springs 29 may be bimetallic so that if one of the contacts tends to overheat through arcing, the corresponding strip 29 bends and causes it to reengage its associated contact. This prevents overheating and tends to cause simultaneous operation of all the contacts. The spring 29 may be of steel and the plate 31, riveted to it, of brass or the substance known under the Registered Trade Mark " Duralumin."
Patent GB-802185-A (GB)
Title: Unsaturated diamine products and their preparation
IPC: C07C209/02
Filed: 1956-06-04
Abstract: The invention comprises the products of addition of two amino radicals to a dimer of a conjugated diene.  The products are prepared by reacting a conjugated diene with free amino radicals generated in a system known to be capable of producing such radicals.  The process is preferably carried out in the liquid phase using a mutual solvent for diene and aqueous components, such as butanol, tert.-butanol, ethanol, isopropanol, acetone, methyl ethyl ketone and dioxane. Exemplified conjugated dienes are butadiene, isoprene, dimethyl butadiene and pentadienes such as methyl 1 : 3-pentadienes.  The free amino radicals are preferably generated in situ by the addition of hydroxylamine or the sulphate, nitrate or hydrochloride thereof, and a metal salt that undergoes oxidation-reduction reaction with the hydroxylamine to form free amino radicals to a solution of the diene. The addition of the hydroxylamine and the metal salt is preferably conducted concurrently.  The preferred oxidation-reduction salt is titanous chloride.  An example describes the conversion of butadiene to octadiene-2 : 6-diamine-1 : 8 in admixture with isomers thereof. The products may be isolated as the hydrochlorides and fractionally separated or may be hydrogenated to the corresponding octanediamine-1 : 8, which may then be isolated as the hydrochloride.

Abstract: 1,192,674. Slack adjusters. ALFRED TEVES G.m.b.H. 10 April, 1968 [25 July, 1967], No. 17249/68. Heading F2E. Automatic compensation for brake lining wear is provided during brake release by a device including a screw-threaded pin 3 on to which a bush 2 is screwed, the two being relatively rotatable to adjust the brake clearance. Such relative rotation is obtained by a screw-threaded grooved member 4 which rotates relative to the pin 3 when a predetermined brake clearance s has been exceeded, and which positively connects the pin 3 to rotate the pin during brake release to close the brake clearance. As shown, brake shoes are acted on by a thrust member 14 located in the end of pin 3, brake force being applied to bush 2 either mechanically or hydraulically. The member 4 is provided with helical grooves 6 into one of which a pin 5 projects with a clearance corresponding to an axial movement of the member 4 through the distance corresponding to the predetermined brake clearance s, so that when the member 4 is moved an axial distance greater than s it is caused to rotate. The member 4 and pin 3 are connected by a roller 8 biased by a leaf spring 9 such that for rotation of member 4 in one direction (i.e. that corresponding to brake release), pin 3 is positively connected thereto, and in the other direction is rotatable relative to pin 3.
