Title: Typing and recording apparatus
IPC: G06C11/08
Filed: 1967-08-11
Abstract: A punched or printed record of data printed on an original 19 by a typewriter or like machine 21 is produced on a record carrier 1 of card or strip form by apparatus comprising a line of dies 42 arranged above a line on the record carrier 1 and operated in groups to punch or imprint a coded impression representative of a character printed by the typewriter, and a distributer arranged to actuate each group of dies in succession along the line in response to electrical impulses from the typewriter keys. The record carrier 1 may comprise a card divided into a plurality of lines, each line comprising twenty character spaces each of four binary bits, the line of dies correspondingly comprising eighty dies, operated in twenty groups of four. The distributor comprises a fixed disc 34 having twenty groups of four radially aligned contact points, each contact point being connected to an electromagnet 37 operating a respective one of the dies 42, and a rotatable arm 36 carrying four aligned contact points connected to a coder 32. Depression of a key 22 of the typewriter closes a switch 31 and causes an electrical impulse to pass to the coder 32, which passes impulses through the contact points of the arm 36 to operate corresponding dies of one of the groups. The impulse also actuates an electromagnet 150 after a period of time caused by a delay element 47, and thereby acts through pawls 146, 147 and a ratchet wheel 145 to rotate the arm 36 into contact with the next adjacent row of contacts on the disc 34, so that the next group of dies may be operated. Key operation.-Impulses from the coder 32 actuate electromagnets 37, one for each die 42. The armature of an electromagnet lifts a link 38 and pivots a lever 40 which depresses the corresponding die 42 against the action of a spring 43. The dies may perforate or imprint the card 1. Line spacing.-A line shift of the typewriter causes a projection 53 associated with the typewriter platen 30 to close a switch 52 and thereby actuate an electromagnet 56. The armature 57 of the electromagnet pivots a pair of pawls 58, 60 to permit a ratchet wheel 59 to rotate a pin feed roller 63 under the action of a coil spring 61. A toothed wheel 67 engages teeth associated with the roller 63 and enables the spring 61 to be wound up. The electromagnet 56 may alternatively be actuated through contacts 151, 152 on the arm 36 and disc 34 respectively, after a revolution of the arm 36 has been completed. In an alternative embodiment, (Figs. lb, 4, not shown), the record carrier (5) comprises a strip having two character spaces per line, and the line feed mechanism is actuated on alternate typewriter impressions.

IPC: B23K15/00
Filed: 1969-01-22
Abstract: In electron beam longitudinal beam welding of continuously delivered steel, particularly alloy or stainless, tube 1, an electron gun 21 is connected to a housing 8 connected to a main evacuating pump 11 and extended upstream and downstream by sleeves 9, 10 the lengths of which co-operate with means near the sleeve ends to maintain partial vacuum in the housing. The welding is effected at a station preceded by stations (not shown) converting a continuously delivered strip into a circular cross-section tube 1. Rollers 2 co-operate with a fixed or displaceable blade 2a to open up the tube for admission of a rod or tube 23 (Fig. 2). Rollers 12 cooperate with a blade 13 for aligning the tubeforming strip edges with the electron gun, and rollers 14, 15 respectively close the tube and nip the edges together before and after welding. Seals 24, 25 (Fig. 2), e.g. of plastics such as P.T.F.E., are provided in contact with the inner surface of the tube 1 upstream and downstream of the housing and may be carried by the rod or tube 23 which may carry a tool 22 for scraping or flattening the weld bead. The seal 24 may have an outwardly projecting longitudinal rib to close the opening provided by the blade 2a. Seal-efficiency-increasing, low vapour pressure, liquid may be fed, through a tube 26 incorporated in the rod or tube 23, to the upstream side of the seal 25. The rod may also be used to connect an additional pump to the tube 1 interior for evacuation thereof. To protect the lower inside surface of the tube 1, and the rod or tube 23, against the effect of the electron beam, the rod or tube 23 is either in part formed by (Fig. 3A, not shown), or carries in a nacelle (Fig. 3B, not shown), refractory material such as a molybdenum bar positioned in the beam path. The refractory material may be cooled by circulating water. Preferably, chambers 18, 19 provided near the ends of the housing sleeves are gently evacuated by pumps 16, 17 (e.g. vane pumps), and, in addition, mechanical, hydraulic or pneumatic sleeve/tube seals 20, 21 are provided at the tube ends. Other pumps, such as 16, 17, may be provided in the vicinity of the housing 8, and two pumps, such as 11, may be provided on either side of the beam. An annular pump may be arranged, at the position 20, to blow a liquid screen tangentially on to the tube to provide a seal. Constant vacuum may be maintained in the welding zone by an auxiliary pressure adjustment pump 111 controlled by means 1111 responsive to welding zone vacuum. The tube 1 is preferably preheated as by deformation of the electron beam, by an additional electron gun 30, or by medium- or radio-frequency induction coils 31 arranged before the blade 13 or, as shown, the gun 21, a screen being preferably provided to protect the electronic lenses.

Filed: 1969-04-30
Abstract: The invention rotates to the winding device of Specification 931,711 for supplying coils of weft sufficient for one pick 'to the dummy shuttles of a travelling ware loom. According to the invention, the blade 31 on which the flyer 32 winds coils of weft 35 is held stationary by two retaining means acting alternately, the change from one to the other being effected to allow a coil 35 to be slid along the blade by a pusher 41. As shown in Fig. 4, a plunger 66 having a forked end engages the edge of the blade when it is retracted to allow a coil of weft 42 to pass, a dummy shuttle being pushed out of a magazine 30 onto a coil of weft 43 serves as the other retaining means. Various other designs are shown, including two plungers pressing on a flat side of the blade near its edges or a spring strip 84, Fig. 7, operating near the free end of the blade 45 and having a finger 86 resting against the blade and another finger 85 entering a hole in the blade to prevent the coil of weft (43, Fig. 4) from sliding off prematurely. In another form, weft is wound on a cylindrical former instead of on a flat blade two plungers engaging diametrically opposite dimples in the former act as one retaining means and the pusher 41 passing through a diametrical slot acts as the other. A similar arrangement employs a former of oval section having a slot for the pusher 41 through its major axis two plungers gripping the former between them to act as the other retaining means. The devices may be used to measure weft for a jet loom.
