Patent GB-795388-A (GB)
Title: Process for the preparation of fatty alcohols
Inventor: BRACONIER FREDERIC FRANCOIS AL
Filed: 1955-07-20
Abstract: Higher fatty alcohols are obtained by reacting the corresponding fatty acids with an excess of methanol in the presence of a catalyst comprising one or more metals or metallic compounds having a hydrogenating catalytic activity at a temperature above 200 DEG  C. and a pressure above 300 atm., so that both the water formed by the reaction between the acid and the methanol, and at least part of the excess methanol are decomposed to yield active hydrogen which reduces the fatty acid to the corresponding fatty alcohol.  The "higher fatty alcohols" referred to are those containing from 6 to 24 carbon atoms. Suitable catalysts are, for example, copper, zinc, cadmium and iron or their oxides and they may be used alone or with a promoter such as chromium or chromium oxide.  In an example tallow fatty acids and methanol are passed through a tube containing active carbon impregnated with salts of chromium and zinc at 320-325 DEG  C. and a pressure of 350 atm. to give a mixture of higher alcohols.

Title: Improvements in shock absorbing devices
IPC: F16F1/371
Filed: 1937-07-31
Abstract: 499,414. Shock - absorbers ; universal joints. METALASTIK, Ltd., and STERN, N.S. July 31, 1937 No. 21307. [Class 108 (iii)] [Also in Group XXIV] A shock-absorbing device comprises at least one rubber block united by adhesion, e.g. cementing or vulcanisation, on opposite sides to rigid elements in order to damp relative displacement of the elements by tension or compression of the rubber which is perforated at right-angles to the direction of stress, rigid plates being provided to contact with a progressively-increasing area of the block with increase in compression. As shown in Fig. 1 a centrally-perforated cylindrical block 1 is formed with flattened surfaces 3 vulcanized to metal plates 4 constituting the rigid elements, which have attachment bolts 5 and are formed integral with plates 7 so shaped that under compression the block is deformed as shown in broken lines. The plates 7 may extend over only a portion of the block when compressed. Several constructions are shown in which a plurality of blocks are arranged in series or parallel and are adapted when compressed to follow a predetermined deformation by the interposition of one or more shaped metal plates or by engaging suitably arranged plates. Fig. 9, for example, shows a device comprising superposed blocks 22, 23, 24 vulcanized to plates 26, 26, 27, 27a and adapted when compressed to engage downward extensions of the plate 27a. Fg. 13 shows the invention applied to a coupling opposite pairs of abutments 31, 32 being secured respectively to the driven and driving members and adjacent pairs being separated by a rubber block 33 surface bonded to plates having extensions 34 which control the deformation.

Title: Improvements in or relating to the manufacture of filament supports
Inventor: GORDON RONALD DUNNING
IPC: H01K3/10
Filed: 1955-07-22
Abstract: 846,862. Making lamps or electron discharge devices; angular bending. GORDON AIRCRAFT COMPONENTS Ltd. Oct. 22, 1956 [July 22, 1955], No. 21354/55. Classes 83 (2) and 83 ( 4). [Also in Group XI] Apparatus for bending into the required spatial relationship and cutting to the required length in one operation all the filament support wires in a glass pinch of an incandescent filament bulb or electron discharge device comprises means for locating and clamping the wires adjacent the pinch, means capable of reciprocating relatively to the wires to engage and bend the wires and means for cutting the bent wires to the required length. In the construction shown in Figs. 2, 3 and 4 the filament support wires 1, 2 and 3 in the pinch are inserted in the slots 6, 7 and 8 of the locating plate 5. Downward movement of the ram 10 first causes the clamping plate 13 to contact the wires and hold them in position under the action of the spring 14 and then brings the cam striker plates 29 and 30 into contact with the rollers 28 of the plungers 21 forcing them apart against the pressure of compression springs 32, the wires 2 and 3 passing through the two outer slots 6 and 8 being bent by the upwardly projecting bars 33 into the required position and cut against the devices 34 and 35 to predetermined lengths. The continued downward movement of the ram 10 also causes the upper anvil 19 attached to the underside of the block 11 to bend and cut the wire 1 passing through the central slot 7 against the lower anvil 20. After completing its downward stroke the ram 10 moves upwards until the anvil and clamping plate are clear of the wires. The two plungers 21 are forced by their springs 32 to the normally closed position and the wires are removed from the slots by first lifting the pinch in an upward direction and then withdrawing it horizontally. In the construction shown in Figs. 5 and 6 the pinch is mounted in its adjustable carrier 51, the four wires 43 extending horizontally, and on the downward stroke of the ram 10 the wires are clamped by the plate 13. Further movement causes the member 37 to be moved against its spring 47 towards the plate 5 and the head 48 is forced between the wires 43 to bend the latter against the faces 40 of the fixed die members 38 and 39. The members 38 and 39 comprise fixed blocks located behind the plate 5 and having rearwardly inclined oppositely disposed inner faces 40 and 41. The face 40 is stepped at 42 and the face 41 is similarly although oppositely stepped to the resilient shape required for the wires 43. Further movement after the member 37 has reached the limit of its travel towards the plate 5 causes the cutter 49 to engage the ends of the bent wires 43 and cut them off by the forward and rearward cutting edges 49a and 50 so that the uppermost wires are shorter than the lowermost wires.
Patent GB-427378-A (GB)
Title: Improvements in or relating to methods of and means for delivering parisons to the finishing moulds of glass forming machines
IPC: C03B9/44
Filed: 1934-07-21
Abstract: 427,378. Glass manufacture. PARFITT, A. W., Stafford House, Norfolk Street, Strand, London.-(Europõischer Verband der Flaschenfabriken Ges.; 10, Breitestrasse, D³sseldorf, Germany) July 21, 1934, No. 21396. [Class 56] Relates to a glassware-forming machine of the continuously rotating type in which each parison, after the parison mould has opened, is suspended from the neck mould or tongs until it is enclosed in the finishing mould. According to the invention, the opening of the neck mould or tongs to release the parison is initiated by the closing movement of the finishing mould and takes place practically instantaneously, in order to prevent distortion of the neck of the parison. The machine comprises two horizontal tables or carriages 10, 13, Fig. 3, which rotate in unison with one another about vertical columns 11, 14, respectively, and support the mould units. The parison moulds 26, Fig. 2, are mounted on the table 10 and the finishing moulds 28 on the table 13, the neck moulds 27 being arranged above and in register with the parison moulds. Each neck mould also becomes coaxial with a finishing mould when they reach a point C on the line joining the axes of the tables 10, 13, the point at which parisons are transferred to the finish. ing moulds. Each parison mould consists of two halves which are pivoted on a vertical pin 31 and are opened and closed by a slide block 33 operated by a stationary cam 32. The halves of each neck mould are pivoted on the pin 31 and they are opened and closed by an arm 41, also pivoted on the pin 31, which has a lost motion connection with one of the mould halves. An arm 49, fixed to the other mould half, is connected by the arm 41 by a spring 47 which lies on one side or the other of the axis of the pin 31 according to whether the mould is open or closed. The finishing moulds are pivoted on vertical pins 55 and are opened by slides 56 operated by a fixed cam 61. A spring 63 connected to the arms of each mould, is so positioned as to cause the mould to close with a rapid or snap action, the slide 56 being released by the cam 61. A tilting mould bottom 65 of the usual type is also pivoted below the finishing mould. In operation, as a pair of mould units, shown in dotted lines in Fig. 2, approaches the transfer position, the finishing mould 28 commences to close and the parison mould 26 commences to open leaving the parison suspended from the neck mould 27 which is kept closed by a spring 54. When the moulds reach the position C, the spring 63 closes the finishing mould rapidly and an arm 52 on one of the mould halves strikes a part of the arm 41 and swings it around the pin 31. This movement carries the spring 47 across the pin 31 and allows it to open the neck mould rapidly. The parison is thus released by the neck mould and is enclosed in the finishing mould, where it is blown to shape by a blowhead operated in the usual way.

Title: Voltage variable capacitive network
Inventor: LUDWIG DAVID ROGER
IPC: H03J3/18
Filed: 1969-04-28
Abstract: 1,244,053. Tuning arrangements. W. J. KRESKE. 28 April, 1969, No. 21578/69. Heading H3Q. A voltage variable capacitance network for providing capacitance across a use device comprises the combination of a plurality of voltage variable capacitor elements coupled in series, each element having a reverse bias voltage variable capacitance characteristic and a forward bias conduction characteristic, means adapting said series for coupling across the use device, and means for providing a selectable bias voltage with capacity for a substantially different reverse bias simultaneously across each of the series coupled variable capacitance elements. Varactor diodes 12, 14 are connected in series, cathode-to-cathode, across terminals 28, 30 of use device 23, a fixed series capacitor 27 of relatively high value preventing shortcircuiting of the D.C. diode bias voltages by the use device 23. Diode 12 is so back biased from a variable control voltage source 20 and over R.F. chokes 18, so as to always act as a varactor. Diode 14 is provided with variable cathode bias from source 20 and its anode is given a fixed bias from offset voltage source 26: when the bias from source 20 is greater than that from source 26, diode 14 is back-biased and the arrangement comprises the two varactor diodes 12, 14 in series. When the bias from source 20 is less than that from source 26, the diode 14 is forward-biased and becomes conductive and the capacitance of the arrangement is effectively that of varactor diode 12 alone. The arrangement can be adjusted to give a capacitance variation which is linear over a wide range (Fig. 7, not shown), which may be extended by using more than two diodes in series, with corresponding offset voltage sources (Figs. 4-6, not shown).

Filed: 1943-12-24
Abstract: 575,031. Scribing blocks, surfacegauges &c. TURNER, A. Dec. 24, 1943, No. 21633. [Class 61 (ii)] [Also in Group XIX] Relates to a supporting column for scribers or surface gauges, test indicator stands and bases &c., fitted with a micro-adjustment for axial movement in a guideway and means for preventing rotation and transverse play therein. The column 6 is located in the hardened cylindrical core 3 of a guide 2 by hard steel balls 7 held under elastic compression between the bore and a hardened cylindrical surface 8 on the column. The balls 7 are held in cages in slots having hardened cheeks 12 lying, in planes parallel to the diametral planes through the balls and the column, axial movement but not rotary movement or shake of the column being thereby permitted. For a column of one inch diameter, the radial dimension of the annular space into which the balls are pressed is made less than the ball diameter by an amount of the order of one-and-a-half to two- and-a-half thousandths of an inch. Alternatively, the column and guide may be grooved for the balls, so as to prevent rotation of the column. A fine-pitched adjusting-screw 20 having a skirt 22 to exclude dirt effects the final adjustment of the column 6 through a lever 16, a spring 24 maintaining contact between screw and lever. A universal mounting slidably and rotatably mounted on a column has a friction clutch 29 with a movable member 30 supporting a rod 31 which receives the appliance to be supported. The clamping bolt 32 for the clutch is slidably keyed to the fixed member 29 to prevent rotation of the bolt when the nut 35 is tightened-up, and a compression spring 37 holds the clutch faces in contact when the nut is loosened.
