Title: Speed variators
IPC: F16H15/38
Filed: 1971-04-20
Abstract: 1338693 Variable ratio friction gear G A LOUIS 20 April 1971 [21 April 1970] 10164/71 Heading F2D In a continuously variable-ratio friction gear in which a number of circumferentially spaced idler rollers 22 are in frictional driving contact between a pair of inwardly facing driving and driven curvilinear cones 16, 50, the idler rollers are tiltable, for ratio change, in a radial plane at right angles to the axis of the cones 16, 50 by a roller 35, on each idler roller carrier 23, engaging spiraloid grooves 37 on a plate 38 journalled at 39 in the casing 42 and turned for ratio change via a worm 45 and worm-wheel 44 connected by straps 47 to the plate 38, the roller carriers 23 being guided and supported in the right angled plane by a roller 31 carried by the casing 42 engaging a profiled slot 29 formed in the carrier 23 and further, by rollers 27 carried at 28 in the casing, arranged at right angles to the roller 31 and engaging surfaces 26 of the carrier 23. In an alternative embodiment (Figs. 6 and 7) the roles of the rollers and supporting and guiding surfaces are reversed, i.e. a roller (67) of the carrier 23 engages a guide surface 69 on the casing 42 whilst at right angles thereto rollers on the carrier support and engage surfaces on the casing 42. The driving and driven shafts 1, 64 are connected to their respective cones 16, 50 via freely floating resiliently connected centre plates 12, the plates 12 being connected via torque responsive rollers 13 and "V"-cam grooves 15 to the driving and driven cones 16 (Fig. 5, not shown), a driven plate 54 being slidably splined on the driven shaft 64, a Belleville spring pack normally urging a light thrust bearing 58 into contact with the plate 54 to hold it clear of a heavy thrust bearing 62 which only becomes operational when high torque at low speeds produces axial movement of the light bearing 58 against the Belleville spring pack to additionally bring in the support of the heavy thrust bearing 62.
Patent GB-437928-A (GB)
Title: Improvements in or relating to the manufacture of rubber compositions from rubber latex
IPC: C08J3/24
Filed: 1935-04-02
Abstract: Vulcanized rubber sheet is made by adding to latex a vulcanizing agent and an accelerator, coagulating, sheeting, and drying at such a temperature that a substantially unvulcanized product is obtained, and maintaining it at atmospheric temperature for a long period, the accelerator being such, and added in such amount that vulcanization proceeds for a period of from one or two weeks to several months.  An activator such as zinc oxide, fillers, colouring matter may also be added to the latex, the additions being preferably converted into aqueous dispersions. According to an example, a mix consisting of 100 lbs. of rubber as latex, 3 lbs. of sulphur, 9 lbs. of zinc oxide, 4 oz. of zinc dimethyldithiocarbamate and 8 oz. of colouring matter is coagulated, creped, and dried for 7-10 days at 70-120 DEG  F.  The dried sheets are laminated and stored for 3-6 months to vulcanize. Another accelerator specified is piperidine pentamethylenedithiocarbamate, which may be added in the proportion of 8 oz. to 100 lbs. of rubber.  Such rubber resists ageing, can be joined with cold rubber solution, is very resilient, and resists abrasion and tearing.

Title: Manufacture of 3-methylal-pentane and 3-methylol-pentane
IPC: C07C29/17
Filed: 1933-04-07
Abstract: 3-Methylal- and 3-methylol-pentane are prepared by subjecting acetaldehyde and butyraldehyde to the aldol condensation, dehydrating the resulting acet-butyraldol, and hydrogenating the 3-methylalpentene-2 so formed.  When the hydrogenation is carried to the alcohol stage, the latter may then be dehydrogenated to the aldehyde.  The aldol condensation is effected with the aid of caustic alkali solution at a temperature of 3--10 DEG  C.; dehydration occurs on subsequent distillation.  The hydrogenation may take place in the liquid or vapour phase in the presence of such catalysts as nickel and copper, using temperatures below 100 DEG  C. for the production of the aldehyde and from 100--200 DEG  C. for producing the alcohol; dehydrogenation is carried out at a temperature above 200 DEG  C. in the presence of, say, copper or zinc. Examples are given.

Abstract: 1,079,280. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. March 11, 1966 [March 17, 1965], No. 10805/66. Heading H4K. In a traffic control system, such as a telephone network or a road or rail network, in which nodes (switching centres or exchanges in the case of telephony) are interconnected by links, the links are constantly supervised as to their condition, whether they are satisfactory for use or have become degraded suddenly or otherwise, and corresponding information is supplied to all the nodes, the information arriving at a node being weighted according as it is received directly or indirectly from the link in question. It is assumed that information received indirectly is more subject to delay or to error than that received directly. The information may be transmitted between nodes in time-division multiplex fashion, and equipment is provided at each node for collating the information according to its weighting (Figs. 2, 8). In a telephone network, each exchange includes a model of the network with means for determining the most suitable route for setting up a desired connection (Fig. 13).

Title: Improvements in electric air blast circuit breakers
IPC: H01H33/16
Filed: 1957-04-03
Abstract: 806,232. Air-blast switches. ALLMANNA SVENSKA ELEKTRISKA A.B. April 3, 1957 [April 14, 1956], No. 10853/57. Class 38 (5). In an air-blast switch having a main " breaking gap " 24, 32, an auxiliary " breaking gap 24, 31 and a shunt resistor 25 enclosed in a compressed air container, the resistance is electrically connected between a wall of the container and one contact 31 of the auxiliary gap, the other contact 24 of the auxiliary gap being connected to or constituted by a contact of the main gap insulated from the wall of the container. When a valve 46 is operated to close a pipe 49 and to open a cylinder 42 to atmosphere at 52, the resulting drop in pressure in a pipe 41 and a cylinder 29 enables the pressure in the cylinder 22 to move a piston 28 to close the auxiliary contacts 31, 24 and connect the resistor 25 in parallel with the main contacts 24, 32. The pressure in the cylinder 22 acts on the blast valve 37 to move it downwardly to open exhaust passages 40 and at the same time to engage and move a valve disc 35 to open the contacts 24, 32. When the valve disc 35 abuts a sealing-ring 36 and closes the outlet to atmosphere from the cylinder 42, compressed air supplied through a pipe 44 increases the pressure in the cylinder 42 so that the blast valve 38 is reclosed and the auxiliary contacts 24, 31 are opened. The main contacts may be reclosed by moving the valve 46 to the right to close the aperture 52 and open the pipe 49 so that compressed air acts on the underside of the disc 35 and a spring 48 is able to reclose the contacts 32, 24.

A keg 9 placed horizontally on a roller unit 7, 8 within a machine framework is turned about its axis until its bung 10 becomes aligned with a rotatable, vertically reciprocable bung extracting auger 39, whereupon the keg is clamped in this position by a unit 16 forced downwardly thereon and the auger raised to pierce and withdraw the bung. The clamping unit comprises a pair of spaced shoes 19 secured to the downwardly extending flanges 17 of a bracket carried by two arms 11 pivoted at 12 and raised and lowered by a power cylinder 20. A subsidiary clamping mechanism to provide a relatively light hold-down pressure to the keg before the shoes engage it consists of two pairs of rollers 26, each roller being carried at the end of an arm 24 pivoted at 23 to the clamping unit, and the ends of adjacently pivoted arms being urged together by springs 27. The auger is mounted on a spindle 37 driven by an electric motor 35 mounted on a cage 33 vertically reciprocable by power cylinders 34, and guided by rollers 31, 32 engaging standards 29, 30. The broken bung, on its removal, together with any other matter received from the keg, is received by a tray 45 which rotates with the spindle 37, and is surrounded by a stationary wall 46 with an opening therein leading to a shoot to which the bung &c. is swept by a stationary deflector extending adjacent and radially of the tray.
