IPC: B21F27/06
Filed: 1928-07-03
Abstract: 294,205. Vereinigte Stahlwerke Akt.- Ges., (Assignees of Wullner, P., and Jung, K.). July 20, 1927, [Convention date]. Reels.-Wire reel cores formed of two wire loops have the bent overlapped ends twisted together, Fig. 4, in a machine comprising half-pinions, one with a central radial projection engaging a recess in the other, which grip the wires and are then brought together and rotated to twist the wires together. Two halfpinions 2 are mounted on a fixed table and the companion halves 1 on slides 26, the halves 1 each having a projection 3 adapted to engage a recess in the half-pinion 2. The wire loops are arranged on plates 29, 30 with their bent-over ends over-lapping, whereupon the slides 26 are moved inwards by means of cam levers so that the wire loops are gripped between the halfpinions, which are then rotated by means of pinions 10, chain wheels 11, 12, bevel gears 13, 14 and a one or more revolution clutch device 21 thrown in by a pedal 25. Rods 28 connected by levers 27 to the slides 26 prevent actuation of the pedal lever 24 unless the half-pinions are brought close together. The shafts carrying the driving pinions 10 are driven by the chain wheels 11 through fine tooth clutches one part of which is connected by shearing pins to the chain wheels to avoid overstrain of the half-pinions. The table is positioned by springs and cams 31, 32 and the upper plate 30 is adjustable by a cam lever 35.

Title: Improvements in or relating to the manufacture of felt articles
IPC: D04H1/06
Filed: 1958-06-17
Abstract: 897,782. Boots; hats etc.; felting. HUCHLER, G. June 17, 1958 [June 21, 1957], No. 19294/58. Drawings to Specification. Classes 17(2) and 63 [Also in Group VIII] In the formation of felt articles, boots, hats, &c. from flat fibrous material, adjoining edge portions are united, during the felting of the whole article, by felting together bluntly abutting edges without overlapping so that the region of the seam has the same thickness as, but contains a larger number of relatively short fibres per unit volume than, the rest of the material. The prepared flat pieces of material are cut using a stencil or template, allowance being made for shrinkage during felting. The edges may be held together temporarily by a zig-zag sewing, by clamps or by hand. Sewing threads may be removed after felting; if retained they become slack during shrinking and act like the fibres of the material. The felted article may be subjected to known further treatment either mechanical or chemical and the fibrous material may be formed of layers of different density, quality or colour.

Abstract: 1303329 Pipe couplings E I DU PONT DE NEMOURS & CO 22 April 1970 [23 April 1969] 19321/70 Heading F2G A bundle of flexible thermoplastic tubes 21 or a single flexible thermoplastic tube (30), Fig. 3 (not shown), is provided with an end fitting which allows a radially deformable hose 22 to be clamped around the bundle or single tube in a fluid tight manner without collapsing the tube or tubes. According to the invention the fitting comprises a thermoplastic sleeve 11 having a first portion 12 formed with a circumferential groove 33 into which part of the hose can be deformed by at least one band clamp 19, 20, a second portion 13 of lesser diameter than the first portion and to the internal surface of which the bundle or single tube is bonded, and a rigid collar 15, e.g. of stainless steel, located within the first portion 12 to withstand the clamping pressure. Annular shoulders 18, 44, having axial extents large enough to prevent deformation by, for example, cold flow under varying pressure conditions, provide abrupt, highly discontinuous ends to groove 33. The axial extent of collar 15 may be less than that of groove 33 so that clamp 20 deforms the sleeve 11 inwardly which prevents shifting to the right of the collar. A third portion 17 of the sleeve may be slipped over the threaded end of a tubular heat exchanger, Fig. 4 (not shown), and secured by further clamps.

Title: Improvements in and relating to the production of nitroparaffins
Filed: 1945-07-30
Abstract: 2,2-Dinitropropane and/or 1,2-dinitro-isobutane are produced by heating isobutane or gas mixtures containing it with nitrogen dioxide in the vapour phase at a temperature of 190 DEG -300 DEG  C. in the absence of a catalyst.  The reaction may be conducted at atmospheric or higher pressures.  The reactants should be substantially dry and contact times (corrected to 20 DEG  C. at atmospheric pressure) of 90-180 seconds are suitable.  The volume ratio of nitrogen dioxide to hydrocarbon should not greatly exceed 2 : 1.  The reaction chamber may be of heat-resistant glass or of other impermeable vitreous, ceramic or refractory material and should be free from materials giving rise to uncombined oxides of iron.  The converter may be that described in Specification 586,203, and may be packed with pieces of non-catalytic refractory material such as heat-resistant glass.  In an example a mixture of 70 per cent isobutane and 30 per cent normal butane by volume is mixed with twice its volume of pure nitrogen tetroxide, the mixture is dried and passed through a converter at 260 DEG  C.  The product is freed from nitrogen tetroxide by bubbling carbon dioxide through it, washed with water and dried over calcium chloride.  The mono nitro paraffins produced are distilled off from the crude oily product under high vacuum and the residue on fractionally distilling under high vacuum yields, a fraction boiling at less than 70 DEG  C. and another boiling at 70-85 DEG  C., both at 1 mm. pressure.  2,2-dinitro-propane, which on reduction with tin and hydrochloric acid yields acetone, is obtained from the first fraction and 1,2-dinitro isobutane, which on treatment with alkali forms a -nitro-isobutene, is obtained as a precipitate by dissolving the second fraction in methanol and cooling the solution in a solid carbon dioxide/methanol mixture.  Further fractionation of the mono-nitro paraffin fraction yields 2-nitro-2-methyl propane and 2-nitro butane.  Specification 527,031 and U.S.A.  Specification 1,967,667 also are referred to.

Title: Thrust reducing or reversing device for jet propelling nozzles
Inventor: KADOSCH MARCEL
IPC: F02K1/32
Filed: 1951-05-10
Abstract: 750,623. Jet propulsion plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. May 10, 1951 [June 16, 1950], No. 19540/53. Divided out of 750,601. Class 110(3) [Also in Group XXXIII] Means for deflecting the jet stream flowing axially through a jet propulsion nozzle of a jet propulsion engine comprises a series of axially-spaced guide vanes which define passages laterally of the jet stream and opening into the atmosphere, controllable means being provided for urging the jet towards the inner ends and into the passages so that the jet issues at an angle to the axis of the nozzle. The jet nozzle in Fig. 2 is formed with an annular orifice 13 in the wall, a series of annular curved vanes 44 being disposed in the orifice. The inner cone 11 is axially movable in the fixed guide 12 in order to vary the cross-sectional area of the nozzle and is also formed with an annular step or barrier 40 which may be covered by an axially movable hood 41. The hood 41 is connected by arms 43 to a ring 23 which is movable axially by means of pulleys 31, 32, cable 29 and pin 27 which slides in a slot 28 in the sleeve 20. When the step is covered as in the lower part of the Figure, the jet stream, which may be the exhaust gas stream of a gas turbine engine, flows axially without deflection, but when the step is uncovered as in the upper part of the Figure. the jet is deflected between the vanes in the orifice 13. In Figs. 4, 5, the jet nozzle has two lateral orifices 13, 13a in which are disposed curved vanes 44 and the jet stream is deflected into the orifices by means of blasts of air under pressure from the slots 54 in the tapered member 53 which is disposed vertically in the jet nozzle. In further embodiments, the jet stream is similarly deflected into the lateral passages by blasts of air under pressure, but auxiliary barriers or obstacles are disposed so that the stream is deflected thereby should the air pressure be insufficient, for example if the gas turbine engine is throttled down. In Fig. 8, vanes 15a, 15b are disposed in orifice 13 and the opening may be closed by means of an axially-slidable sleeve 13a. When the jet stream is to be deflected, the orifice is opened by rearward movement of the sleeve, and suction is applied to the slots 15c. The vanes may be so curved that the jet stream issues with a forward component thus exerting a braking effect upon an aircraft in which the device is fitted. Specifications 691,302 and 691,948 [Group XXXIII] are referred to.

Title: Digital stop watch
IPC: G04G9/00
Filed: 1976-05-12
Abstract: 1515437 Electronic timepieces DAINI SEIKOSHA K K 12 May 1976 [20 May 1975] 19550/76 Heading G3T [Also in Division G5] An electronic digital stop watch has an electrochromic display device and a control circuit which, when a manually operable switch is closed, sequentially produces first and second control signals, the first signal causing a reverse erase voltage to be applied to the display device to wipe out any remanent display and the second signal enabling application of a voltage to produce a display in accordance with the contents of a counting circuit of the timepiece. Display device Fig. 2 (not shown) shows a device for displaying two alpha-numeric characters. A pair of segmented electrodes (metal oxide) are formed on a glass plate 9; a film of electrochromic material 11 (e.g. M 0 O 3  or WO 3 ) is formed on the electrodes by vacuum evaporation and an insulating layer 12 is deposited on the film. A second pair of electrodes 13 are formed on the layer 12 or on a glass plate 14. The glass plates are joined by an adhesive 15. Stop watch circuit. Figs. 3, 4. A timing signal at 100 Hz from a frequency divider 17 steps counters 19-24 which count from 1/100 secs to tens of minutes. The BCD coded contents of the counters are decoded by respective decoders 25-30 to produce segment signals which are applied to respective segment driving circuits 31-36 to drive a display device E C in conjunction with digit drive outputs from drive circuits 37-42. The segment and digit drive circuits are controlled by the second and first control signals respectively, which signals are produced by a control circuit 45 in response to signals from a switching unit 44 and manual switch 43. Fig. 4 shows the segment drive circuit 31 and digit drive circuit 37. Segment signals are delivered from output terminals 25a-25g of decoder circuit 25, to a respective AND gate 47a-47g together with the second control signal. The outputs of gates 47 control transmission gates 49, 50 connected to segment electrodes a-g. Likewise transmission gates 52, 53 are controlled by the first control signal and control the potential of electrode X. When switch 43 is closed, the first signal (waveform 61Q) Fig. 6 (not shown) commences at time to and continues until t 1 . At t 1  the second signal commences and continues until t 2 . The first signal turns on Tx gate 52 to apply potential IV D  to electrode X. Since at this time the second signal is not present the Tx gates 50 of all the drive circuits will be ON so that potential OV D  is applied to all the segment electrodes. Thereby any display present is erased. When the second control signal appears, the potential OV D  is applied to electrode X. The second signal enables AND gates 47 to pass output signals of decoder 25 which selectively turn ON Tx gates 49 so as to apply potential IV D  to appropriate segment electrodes whereby to effect a display.

Title: Improvements relating to infinitely variable speed drives for vehicles
IPC: G05G7/04
Filed: 1967-04-28
Abstract: 1,142,114. Change-speed control. GEBR. EICHER, TRAKTOREN - U. LANDMASCHINENWERKE. 28 April, 1967 [4 Nov., 1966], No. 19671/67. Heading F2D. The ratio of an infinitely variable hydrostatic gear for a vehicle such as an agricultural tractor is set to a desired value by a hand lever 3 and can be varied or reversed by operation of a pedal 17, the ratio returning to the desired value on release of the pedal. The hand lever 3 is linked to a bell-crank lever 7 which is linked to a lever 10 fast with a shaft 11 having a lever 12 connected by a rod 13 to a lever 15 which is pivoted at its midpoint 16 to a lever 18 and is pivoted at 20 to a rod 21 which is connected to a lever 23 adjusting the transmission. The lever 18 is fast with the pedal 17 and is pivoted at 19 to a fixed part, and the pivot point 16 bears against a rubber buffer 26. On movement of the hand lever 3 from the position I, in which the vehicle is stationary to a position II, the resistance to movement of the adjustment device operated by lever 23 holds the pivot 20 stationary and the pivot 16 moves, compressing the rubber buffer 26. On further movement of the lever 3 towards a position III the pivot 16 does not move further and the pivot 20 is shifted to the right, thus moving the lever 23 and operating the adjustment device to give forward movement, the position of the lever determining the ratio, and the lever 3 being retained in its set position by friction discs. If the speed is to be increased above that set by the lever 3, pedal 17 is pivoted in the direction of arrow A. The resistance provided by the friction discs acting on the lever 3 is greater than that of the adjustment device, so that the end 14 of the lever 15 is held stationary and the lever is pivoted anti-clockwise about this end to adjust the ratio. On release of the pedal a restoring device (see below) returns the lever 23 and pedal 17 to their original positions. If the ratio is to be reduced or the vehicle reversed, the pedal 17 is pivoted in the direction of arrow B, the maximum reverse position of the linkage being shown in chain-dotted lines. The adjusting lever 23 is fast with a shaft 24 which is fast with a plate 27 (see Fig. 4) having a cam slot 28 co-operating with a guide pin 29 on a lever 38 which is pivoted at 39 and actuates the adjustment device. The guide pin 29 is also connected to a rod 31 connected by a centring spring 34 to a housing 35 to provide the restoring force for returning the adjustment device to its preset position on release of the pedal 17. The housing 35 can be given a slight pivotal movement by an eccentric adjusting means in order to enable the speed to be set accurately to a low value to provide a constant crawling speed. The lever 23 is also connected to the speed control member of the driving engine, such as the regulator rod of a diesel engine, so that when the selector lever adjusts the ratio to give increased speed the fuel supply to the engine is increased correspondingly.
