Title: Improvements in or relating to metal working machines
Inventor: REDMAN ALBERT MAURICE
IPC: B21D7/028
Filed: 1955-12-30
Abstract: 808,320. Angular bending. WILMOTBREEDEN Ltd. March 28, 1957 [Dec. 30, 1955], No. 37503/55. Class 83 (4). A machine, for bending bars or strips around a former, as claimed in Specification 784,950, is modified by the provision of two or more workengaging rollers, or banks of rollers, mounted one above another upon the carriage to enable two or more workpieces to be shaped simultaneously, the rollers acting on the different workpieces being independently hydraulicallyloaded to ensure equalisation of shaping pressure on the workpieces. A carriage 15 moves around two fixed bending formers, one above the other, each former having a separate clamp for clamping one end of a workpiece thereto. Two pairs of rollers 11, 12 and 13, 14 are mounted on the carriage, one pair above the other opposite the formers. Each spindle 21 of the rollers is mounted in bearings 20 slidable in the carriage 15 about a quarter-of-an-inch transversely to the spindle. The bearings are hydraulically loaded towards the work by rods 23 having heads 24 in cylinder bores 25 to which pressure fluid is supplied from a cylinder 2 through ducts 27.

A pump or motor comprises two rotary cylinder blocks 16, 23 with their axes at a fixed or adjustable inclination, and piston assemblies 50, 51 on piston rods 49 located axially by a ring 54 engaging a groove 53 in each piston rod, the ring acting to maintain the piston assemblies axially centralised relative to a plane symmetrically positioned relative to the cylinder block axes. The piston heads may be integral with the piston rods (as shown), or may be connected to the piston rods by ball joints. In the embodiment shown, the displacement is variable, together with the direction of flow or rotation, by tilting block 23 relative to block 16, by moving a servopiston 59 acting through support member 20 and a thrust block 17 slidably mounted in the housing and supporting block 23. Support 20 also pivotally supports ring 54, Fig. 3 (not shown), such that the ring is automatically centralised relative to the plane of symmetry between the block axes on adjustment of block 23. Block 16 is directly driven by or drives shaft 11, and is coupled to block 23 by a universal joint 26 including a tongue 14 engaged by a resiliently loaded element 75 subjected to the pressure from the low pressure side of the pump or motor. Cylinder parts 29, 38 register with kidney parts in the thrust blocks 10, 17 to control flow to and from the cylinders, the kidney parts being connected to common inlet and outlet parts, Fig. 2 (not shown). Hydraulic balancing is provided between the cylinder blocks and the thrust blocks, and between thrust block 17 and the housing. A through - passage 49B in each piston assembly balances the pressures in the corresponding cylinders. Lubrication of joint 26 is provided by working liquid from a cylinder 27 via passages 71, 72. In a fixed displacement embodiment, Fig. 7 (not shown), drive is transmitted between the cylinder blocks by bevel gears. In Fig. 8 (not shown), both cylinder blocks are pivotally mounted in the housing and are rotated by universal joints on a drive shaft extending through the housing.

Title: Improvements in or relating to circuit components for performing logic functions.
IPC: H03K19/16
Filed: 1966-09-05
Abstract: 1,158,909. Logic circuits using magnetic elements. SIEMENS A.G. 5 Sept., 1966 [6 Sept., 1965], No. 39555/66. Heading H3B. A logic circuit component includes a plurality of magnetic thin film elements having uniaxial magnetic anisotropy, each film having supply leads electrically connected to the film and a control input for providing an external magnetic control field to the film, the arrangement being such that a voltage is developed in the film in a direction transverse to the supply leads due to the transverse Hall effect in the presence of the control field. The logical function performed depends on the angular relationships between the control field, the easy axis of the film and the supply leads of the plurality of films. In the drawings M is the easy axis of film 4, line 3 is the supply lead, lines 1 and 2 are the control lines and 5 is the output lead. An output is produced only when the resultant magnetization in the film lies at an angle, other than 90 degrees, to line 3. Figs. 4 shows a circuit for performing the disjunction (OR) function. An input on either line 1, 2 rotates the magnetization vector through 45 degrees and an output is produced. If the remanent magnetization vectors in the two films of Fig. 4 are opposed the device performs the antivalence (EXCLUSIVE-OR) function. The function performed by the device of Fig. 6 is equivalence (parity), an output being produced only if the inputs to both lines 1, 2 are the same. Fig. 7 (not shown) includes two films arranged in the same way as film II in Fig. 6. An output is produced unless inputs are supplied to both lines 1, 2 (Sheffer function). In Fig. 8 an additional film is provided, without a control line, which converts the preceding embodiment into a conjunction (AND) circuit. The circuit of Fig. 4 may be similarly modified by provision of an additional uncontrolled film, in this case having its easy axis parallel to that of film II in Fig. 6. This circuit gives an output only in the absence of any input (Pierce function).

Title: Transporter vehicle for transporting sections of a bridge
IPC: B60P3/40
Filed: 1974-09-11
Abstract: 1473221 Transporting bridge sections MAGIRUS-DEUTZ AG 11 Sept 1974 [23 Oct 1973] 39658/74 Heading B7B [Also in Division E1] Bridge sections are carried side-by-side on cross members of a vehicle. At least some of the cross members are extensible and carry pivoted holding arms so that the bridge sections can be manipulated and connected to form two bridge halves before transfer to a bridge laying vehicle. As illustrated, the vehicle has four cross members 7-10 supporting four bridge sections 11-14 with their wheel track surfaces 15, 16 vertical. In the finished bridge, sections 11 and 14 are connected together at ends 19 and 22 to form one longitudinal half of the bridge, and sections 12 and 13 are similarly connected to form the other longitudinal half. Before transfer to the laying vehicle, sections 11 and 12 are connected to each other, as are sections 13 and 14. To arrange the sections for this connection, rams 35, 36 are operated to pivot holding arms 31, 32 outwardly from their Fig. 3 positions to horizontal positions. Further rams push the sections out on to the holding arms and then push extensions 25, 26 from the cross members so that the Fig. 4 condition is reached. Finally, the holding arms turn the sections inwardly through 90 degrees and the sections are moved towards each other so that their struts 23 and 24 can be joined. The bridge laying vehicle, Figs. 6 and 7 (not shown), for a laying jib which, after insertion into a guideway between sections 11 and 12, draws the sections off the transport vehicle. The transport vehicle may also carry legs 40, 41 and a transverse bearer 42 for supporting an end of the bridge if it is not long enough to reach across the relevant obstacle. Appropriate positioning of the laying vehicle after the latter has received the bridge sections will allow the legs and bearer to be connected to the sections and then to be drawn off the transport vehicle as the laying vehicle is moved away, Fig. 8 (not shown).
