Title: Switching a bistable device by means of an input signal which steps between two separate values
IPC: H03K5/01
Filed: 1965-06-17
Abstract: 1,039,858. Transistor pulse circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 17, 1965 [July 1, 1964], No. 25658/65. Heading H3T. In apparatus for controlling the state of a bi-stable device, delayed bipolar pulses are generated from each step of the input signal, further pulses being derived fom the bipolar pulses so that the bi-stable device is set in response to each rising step of the input signal and reset in response to each falling step whereby the bi-stable device generates a signal which is preferably a delayed replica of the original signal. In Fig. 4A (not shown), rectangular pulses are amplified by a two-stage directcoupled transistor amplifier and fed to the transmitting winding of a magnetostrictive delay line the output of which at 22 takes the form of a bipolar pulse corresponding to each step of the input pulse. The bipolar pulses at 22 are amplified at 84, 88 and fed via a phasesplitter 104 to amplifying transistors 120, 126 diodes 130, 134 eliminating the unwanted halves of the bipolar pulses so that the waveform at 34 includes a positive-going pulse corresponding to the leading edge of each input pulse whilst that at 36 includes a positive-going pulse corresponding to the trailing edge of each input pulse. These pulses are gated by clock pulses from 42 in AND gates consisting of diodes 148, 164 and capacitors 147, 152 and used to set and reset the bi-stable circuit comprising transistors 150, 156 so as to provide antiphased outputs at the collectors. The clock pulses 42 may be derived from the input.

Title: Improvements in or relating to the moulding of articles from suspensions in liquid
IPC: D21J3/00
Filed: 1946-08-27
Abstract: 668,262. Moulding hollow articles from suspensions of cellulose &c. in liquids. PIERSON, G. Aug. 27, 1946. [Jan. 14, 1944; Feb. 2, 1944] Nos. 25680/46 and 25681/46. Class 87(ii). Hollow articles are moulded from a suspension of cellulose &c. in liquid by means of a permeable mould covered or partially covered by a permeable and deformable element which projects into the liquid and is held in the required shape by the mould, the arrangement being such that when the suspension is induced through the deformable element and mould by suction to form the moulded article and the mould or a part thereof is then withdrawn from the element; the latter is deformed and separated from the moulded article. As shown in Fig. 3, the mould is formed in two parts 2, 2a with a gap 2b between them and it is covered by a permeable and flexible pocket 9, a portion of which passes inwardly through the gap 2b and has an annular helical spring 10 disposed therearound. When the part 2 of the mould is raised, the bottom portion 2a remains stationary as shown in Fig. 4 and owing to the inward pull of the spring 10, the pocket 9 assumes a bi-conical shape whereby it is separated from the moulded article 1. Alternatively the two mould parts may abut each other and the inward contraction of the pocket is effected by two laterally movable forks located at the upper end of the pocket. In a further modification an auxiliary shaper 12, Fig. 9, comprising arcuate sections 13 of wire gauze hingedly mounted at their upper edges on a ring 14, may be interposed between the pocket 11, Fig. 7 and a single part mould 2, the pocket 11 being attached to the sections 13. On raising the mould 2, the sections 13 and pocket 11 are pulled inwards by springs 16 arranged around the ring 14. The auxiliary shaper may be provided with an additional and separate base portion 12a, Fig. 8 secured to the bottom of the pocket 11 and mounted on a rod 17. On removal of the mould 2, the pocket 11 is detached from the bottom of the moulded article 1 by raising the rod 17 and base portion 12a, the sections of the shaper 12 being pulled in by the tension exerted by the pocket 11 when the base 12a is pulled upwardly. In another modification a twopart mould 2, 2a, Fig 10, with a gap 2b between the parts has its upper part 2 surrounded by a deformable element comprising a wire gauze member 18 similar in construction to the member 12, Fig. 9. The lower ends of the sections of the member 18 are secured by members 20 passing through the gap 2b to pivot pins 21 joining articulated arms 22, 23 linked by a member 24 and supported by members 25. A compression spring 26 thrusts upwardly against the member 24 so that on removal of the mould part 2, the sections of the member 18 are drawn inwardly from the moulded article.

Abstract: 943,505. Printing and stencilling apparatus. M. G. LANNER. July 17, 1961 [Aug. 6, 1960], No. 25760/61. Heading B6C. A marking machine for reproducing the pattern of a dress or the like on a textile fabric or other sheet material by transferring thereto the contours of templets placed upon the laidout material through the application of a colouring substance to the material in areas not covered by the templets and in which a net is positioned over the templets during the colouring for maintaining them in their correct positions is characterized by the provision of means for moving the net from a position overlying a table top upon which the material is mounted to a position uncovering the top, and vice versa, and by means for vertical movement of the top so that when the net overlies the top the latter may be raised to abut the net. In the machine shown the pattern of the templets 4 is transferred to the upper surface of the top layer of a superimposed bundle of textile fabrics 3 by means of. colour application devices (not shown) traversible by a carriage 5 along the table top 2. A net 6 is supported by drums 11, 12 which are rotatably mounted in the framework associated with the top 2 through shafts 9 and 10 each of which also carries a chain wheel 13 or 14 at each end. These wheels support endless chains 15 carrying fingers 16 to one end of which the longitudinal edge portion of the net 6 is secured. The other ends of the fingers project into an endless guide channel 17 extending along the chain 15 and carry freely rotatable rollers 18 which engage a side wall of the channel. Rotation of the shaft 9 from a motor drive through a belt and pulley 20, 19 actuates the chains 15 and drums 11, 12 to move the net 6 from either a position below or above the top 2. The latter is moved vertically by a motor drive which synchronously rotates two shafts 21 disposed at each longitudinal side of the machine. These shafts mount a plurality of sprocket wheels 22 which are connected to a frame 24 secured to the underside of the top through chains 23 such that shaft rotation will cause the chains to be either wound on or off the sprockets to thus raise or lower the top. Limit switches are provided to prevent starting of the net driving mechanism whilst the table top is in its upper position and to stop the upward movement of the top as the fabric thereon abuts the net.
