Abstract: 1,199,096. Telegraphy. SIEMENS A.G. 17 Sept., 1968 [18 Sept., 1967], No. 44112/68. Heading H4P. A telegraph transmitter includes a keyboard for transmission of variable messages and an arrangement for transmitting a preset message. Operation of a key BuT or ZiT sends a pulse on a corresponding lead to a diode matrix D which outputs a corresponding parallel-bit 5-bit signal to a first store Sp1. The first store feeds a second store Sp2 connected to a dynamicizer PSU which outputs a 5-bit serial signal. If a figures key ZiT is operated after a letters key BuT the relevant function signal is inserted in the second store Sp2 by way of units U1, U2. If two keys are operated with an insufficient time interval the keyboard is locked and an alarm given by way of units K, AL. To transmit a preset message a unit passes character rate pulses from the dynamicizer PSU to each line of a group of lines in turn. The lines are connected to the movable contacts of the keys BuT, ZiT via a plugboard so arranged that the required sequence of characters is generated.

Abstract: 1444742 Directional receiver for ultrasonic waves TOKYO SHIBAURA ELECTRIC CO Ltd 20 Sept 1973 [22 Sept 1972 13 Feb 1973] 44127/73 Heading H4D The directivity pattern of an ultrasonic wave receiver comprising an array of co-planar transducers, whose outputs are added, multiplied and amplitude-weighted (not necessarily in that order) is made similar to some ideal repetitive pattern by establishing weighting factors dependent on the coefficients of terms of a Fourier series representing the ideal pattern. In the Fig. 3 embodiment the outputs of transducers 1 are paired such that the transducers spaced by D feed multiplier 2a, those spaced by 2D feed multiplier 2b, and so on up to a spacing of 6D. The D.C. components of the multiplier outputs are extracted by filters 3a- 3f then weighted at 4a-4f in accordance with the Fourier coefficients. The weighted components are summed at 5 to give a signal for driving a CRT display indicating the direction (unambiguously within a limited angular range) and intensity of the ultrasonic wave source. In further embodiments some transducer outputs are added and the sum signals are multiplied together (Figs. 8 or 9, not shown) or addition and weighting may precede the multiplication (Fig. 9) or weighted transducer outputs may be summed and then multiplied by the amplitude-limited output of one transducer (Fig. 11, not shown).

In one embodiment, a lower die 3, 3<SP>1</SP>, of each set is horizontally displaceable by devices 7, 8 in a tool carrier 4, 4<SP>1</SP> which is connected to a hydraulic cylinder 6 in a movable frame 5, 51. An upper die 2, 21 of each set is pivotable by a device 12 about a horizontal axis 11. The radius of the bending surface of each die increases from one end of the die to the other so that when the dies are set by the devices 7, 8, 12 relative to each other for a particular plate thickness, a constant gap is formed between the dies of each set. The bending radius produced at the plate edges is thereby dependent on the amount of insertion of the plate into the die gaps (Figs. 5-7, not shown). In another embodiment, the tools are formed by rolls (Fig. 8, not shown).

Protuberances (50), 52 on the other face of the flange 16 co-operate with inclined guide plates 46, 48 to provide a wedging action to press the flange 16 against the flange 44. The offset weight of the pump also assists in pressing the flanges together. The co-operating faces of the flanges 16, 44 are lined with stainless steel, and the protuberances (50), 52 may also be of stainless steel. The hoist cable 28 is secured to the pump at such a position that the lower edge of the plate 16 has a wiping action on the face 55 as the pump is lowered, so as to clean the face. This position is offset to one side of the centre of gravity of the pump whereby a slight rotation is given to the plate 16 as it is raised to prevent it becoming stuck. The plate 16 and protuberances (50), 52 may be replaced by a wedge-shaped plate, the inclined guide plates 46, 48 then being replaced by an apertured plate similar to the flange 44, either this plate or the flange being tapered to match the wedge-shaped plate.
