IPC: F16C11/04
Filed: 1969-12-04
Abstract: 1,265,903. Clamps. N. F. SHIRES. 28 Oct., 1970 [4 Dec., 1969], No. 59158/69. Heading E2B. A device for supporting a load on an elongate vertical member 1 includes a gripping means 2 and co-operating presser means for pressing the gripping means and so constructed that the device can be slid up and down the member and at each height attained will be self-supporting by virtue of the gripping means being pressed by the presser means against the member. The device also includes a pivotable member 7 which bears the load and is pivotally connected to the gripping means and has a portion 9 which, when the device is in use and a downwardly acting force acts on the member 7, engages the member 1 thereby limiting the extent to which the load can cause pivoting of the member 7, the arrangement being such that a portion of the vertical member is then gripped between the gripping means and the said portion 9 of the member 7 and the device does not drop. As shown, the gripping means comprises members 2 pressed apart by springs 5 encircling rods 4 slidable in holes in the members, and the member 7 has a hole 8 by which the load is attached and is pivoted on a pin 6. The member 1 is channel-shaped in section and has flanges which are gripped between the members 2 and parts 9 of the member 7. In modifications, the member 1 is (a) C-shaped in cross-section and (b) channelshaped in cross-section, one flange being gripped between a single member 2, pressed towards the web, and a wedge-shaped part of the member 7; the latter includes a portion which engages the member 1 on the outside face of the web thereof.

Abstract: 1288467 Telegraph exchanges SIEMENS AG 18 Aug 1970 [19 Aug 1969] 39652/70 Heading H4P In a telegraph exchange in which a plurality of processing units co-operate with a common storage unit itself divided into a plurality of subsidiary storage units, with connection between incoming and outgoing lines being performed by a processing unit, two substantially identical control programme units are employed controlled by a commando unit providing an input of command data into, and the output of reporting data out of the common storage unit. In the event of breakdown of one of two programme units the other takes over; the storage unit is also duplicated, or with respect to individual subsidiary storage units, partly in duplicate. A store input-output control unit is provided in the common storage unit via which each of the processing unit have access to the storage unit. Access to the operating store or the sub units comprising the store may be effected cyclically. A store sub unit SB1 &c., Fig. 3 may contain one or more core stores KS connected by a store interface to control SEAS. Each core store KS1 &c. contains a core matrix (110, 120), Fig. 4a (not shown), an address section, write in, read out and a control section for generating cycle control signals. Core store KS1 may contain the first thousand words and KS2 the next thousand hence the highest value bit in the store address is employed to direct a cycle to KS1 or KS2. Parallel operation may be formed by store input/output control SEAS and majority decision techniques may be employed. Store sub units, preferably particular ones, may also include parity check facilities. In order that SEAS will operate as rapidly as possible, information indicating whether the store sub units are in a seized or free condition is retained in a store sub unit seizing a register. Store sub units may employ interleaving in its operations, i.e. the cycles running simultaneously, with cycle starts staggered in time by the operation of SEAS. Anticipation may be employed by giving high priority to store sub units with short cycle times. Before the end of the access time, sub units SB signal an output condition to SEAS, i.e. while control SEAS is handling the next application the output circuit (B) of SEAS is effecting the information output from the previously selected store sub unit SB to the associated output destination processing unit VE &c. The highest speed of operation is achieved when the cycle applications are distributed to greatest extent throughout the different sub units SB.

Abstract: 1317374 Making springs; coiling helices VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY INSTITUT MEDITSINSKIKH INSTRUMENTOV 12 March 1971 6734/71 Headings B3A and B3E A method of forming a helical spring, e.g. of conical shape with a thickened tail for medical stomatological channel fillers, from a wire 1 is characterized in that each coil of the spring is formed by bending successive portions of the wire on a support 4, by means of a reciprocating striker 5. The wire and the support are suitably rotated and displaced along the axis of rotation. The wire 1 is clamped in a holder 2 in line with a shaft 3 on which are mounted a prismatic rotatable support 4, a reciprocable striker 5 and an apertured guide plate 6 (Fig. 1) which receives a bent end of the wire. After the first bending operation the striker and support are rotated a predetermined angle (Fig. 2c, not shown) and a further bending is effected. After a complete revolution of the striker and support the coil shown in Fig. 3 is formed. The shaft is rotated by an electric motor 8, Fig. 4, through a belt drive 7 and is displaced axially by a cam 21 actuated by a rack and pinion gearing 20 said cam engaging a cam follower 22 in contact with a disc 24 on the shaft (Fig. 4). Rigidly secured on the shaft is a housing 9 carrying double-arm levers 10 and 11 pivoted at 12 and 13 respectively. The support 4 is oscillated by linkage mechanism 17 as the housing rotates which determines the angle of helix of the spring. The shaft freely passes through a cup-type cam 18 having an outer fluted profile engaged by the lever 10 and a smooth inner profile engaged by the lever 11. Alternatively, the striker is actuated by an electromagnetic, hydraulic, pneumatic or other drive while the rotary motion may be imparted to the wire blank instead of the shaft.

The arrangement shown comprises two slit systems which are mirror images about the line Y-Y and are suitable for use in the double beam spectrometers described in Specifications 1,250,942 and 1,161,432. Each system comprises a cassette 31 including four juxtaposed rollers 32 at least three of which have been electrolytically treated as described in Specification 1,153,167 to provide three collimating slits of various widths. Each cassette 31 is mounted on a plate 33 provided with an arm 55 and held by springs 39 against glass balls 37 so as to be capable of rotation. Plate 33 is sandwiched between other plates to form an assembly 35 which is slidable in the Y-Y direction on guides 41. Each cassette can thus be moved in the Y-Y direction to bring a slit of desired width into registry with the respective ion beam and can be rotated to allow for beam curvature in the plane of the drawing. Sliding and rotation are effected by a pin 53 or 54 bearing against the arm 55 and against the assembly 35. Pin 54 is carried by a rod 44 having an end bearing 60 urged by a spring 62 against a cam 58 which is rotated to move the rod axially. Tilting of the rod 44 in a spherical bearing 52 to rotate the plate 33 is effected by a micrometer assembly 64 acting on the rod 44 through a spherical bearing 66. The rod 44 is a vacuum sealed by a metal bellows 46.
