Filed: 1925-12-04
Abstract: 268,850. Borel, C. Dec. 4, 1925. Feeding webs.-In punching-apparatus for preparing perforated strips for use in statistical machines, the punching-mechanism, Figs. 4 and 6, is controlled 'by four double magnets 167 corresponding to the four holes of the code and by four punches 160. A Maltese cross 14 rigid with the roller 11 has slots 15 coacting with a pin 16 on a crank arm 17 rigid with a disc 122 and with a collar 124, the latter co-operating with a bell-crank carrying the armature magnet u which normally, during the punching, is energized. After punching, this magnet is deenergized, the parts are as shown in Fig. 6, and the pin 16 in a slot 15 feeds the sheet 1 one space. When, however, the magnet u is energized at punching, the parts 124, 122, 17 slide to the right on their squared shaft 120 121, the pin 16 leaves the Maltese cross and the latter, instead of being able to pass through a slot 123 in the disc 122, is held locked by the full circumference of the disc.

Title: Spark Erosion Method and Apparatus.
IPC: B23H1/02
Filed: 1966-10-13
Abstract: 1,168,610. Spark erosion. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 13 Oct., 1966 [16 Oct., 1965], No. 30847/69. Divided out of 1,167,853. Heading B3V. [Also in Division H3] In the spark erosion of a workpiece 35, a capacitor 61, 62 is connected between the workpiece and an electrode 33 and is charged from a pulsed voltage source 40, each charge period commencing with the beginning of a pulse and terminating during discharge across the spark gap. The capacitance 62 may be the parasitic capacitance between the electrode and workpiece and the variable capacitance 61 may be the anode capacitance of the pentode 33. The grid of this pentode is controlled by a double tetrode 62 which also controls the grid of a cathode follower pentode 31. This grid receives pulses from tetrode 30 supplied from the pulse source 40. During a spark discharge, the resulting voltage drop across the spark gap triggers the grid of double tetrode 32 causing it to conduct. This in turn biases pentodes 31, 33 to cut-off whereby the charging of the capacitors ceases. Specific examples are given of the values of the components used in the circuit.

[Class 69 (ii)] [See also Group XXII] In a punch or riveting press, wherein the movable head is actuated through a liquid of constant volume and is moved up to the work by a low-power piston, whereupon the working stroke is effected by a high-power piston, the movable head and the two pistons are disposed coaxially, to form an easily transportable assembly. A press for riveting or punching comprises a movable ram 1 engaging within a cylinder 4 which is in screw-threaded engagement with a cylinder 5. The approach movement of the ram is effected by a piston 2 causing liquid to pass from cylinder 5 into cylinder 4 through orifices 10. The plunger of a piston 3 then closes the orifices 10 and enters the bore 9 of the ram, after sealing the cylinder 4 at the joint 8 to effect the riveting or punching operation at high pressure. Escape of fluid is prevented during the complete cycle of operations by two high pressure joints 8, 40, arranged between two low pressure joints 6, 1<2>. The admission of pressure fluid behind the piston 3 initially occurs through restricted passages 3<2>, 3<3>, the rapid movement of the piston occurring only when a projection 3<1> has cleared the inlet 18<1>. The initial position of the piston 2, and therefore of the ram 1, is controlled by a handle 26 in screw-threaded engagement with a projection 2<1> on the piston. The valve controlling the admission of fluid to the pistons 2, 3 is operated by a lever 12. A modified form is described wherein a pipe provides constant communication between the chamber 5<2> of the cylinder 5, and the chamber housing the spring 24.

Title: Treatment of artificial silk
IPC: D02J1/22
Filed: 1928-10-30
Abstract: 323,846. Ellis, G. B., (Soc. pour la Fabrication de la Soie Rhodiaseta). Oct. 30, 1928. Yarns and threads.-Artificial silk threads composed of cellulose esters or ethers, particularly of cellulose acetate, are reduced in denier by stretching in the dry state while the threads are heated to a temperature such as will render the thread substance plastic, for example, in the case of cellulose acetate to 185‹ C. Operating in this manner it is possible to stretch the threads to the extent of 100 per cent or more, and moreover to obtain filaments of 0.1 deniers. The stretched threads have increased wet and dry strengths, and a higher elasticity; the lustre may also suffer variation, particularly if the stretching is carried out at lower temperatures when the threads become more and more matt in appearance. The stretching may take place continuously with the spinning of the threads, or during later operations such as throwing, doubling, skeining or warping; and it may be carried out either as a continuous operation by passage between one winding device and another moving at a higher peripheral speed, or by stretching in the form of skeins. The filaments of the threads to be subjected to the stretching treatment may be twisted or parallel. With the cellulose ester or ether composing the thread there may be mixed softening-agents such as triphenyl phosphate. Specifications 198,023; 233,384, [Class 2 (ii), Cellulose &c.], and 277,089 are referred to.

Title: Method of manufacturing a heat-resistant fibrous material
Inventor: BUTTER KARL
IPC: C04B30/02
Filed: 1963-08-14
Abstract: A strong heat-resistant fibrous material is prepared by felting together under pressure, glass or quartz fibres of diameter about 1 micron and of length about 1 mm. and by simultaneously supplying sufficient heat to plasticise a bonding agent which serves to bond the fibres together at the points of intersection.  The bonding agent may be the material of the fibres themselves, the heating then being controlled so that only the surfaces of the fibres become softened and thereby bonded together.  Alternatively fibres, e.g. glass fibres, may be included which have a lower transformation temperature than the main body of fibres and heating them takes place to a temperature between the transformation temperatures of the two kinds of fibre. Alternatively the bonding agent may be a pure metal, e.g. gold or silver which may be added in fine powder form or in solution in a form in which it is reduced to the pure metal during the heating process.  In a further alternative, the bonding agent is a sinterable compound or mixture, e.g. tungsten carbide, having a sintering temperature below the transformation temperature of the fibres.  The glass or quartz fibres may be crimped to increase the strength of the fibrous material produced.
