Title: Transducing devices
IPC: H03H9/02
Filed: 1974-07-09
Abstract: 1473647 Surface wave devices EMI Ltd 9 July 1974 [9 July 1973] 32684/73 Heading H3U An electro-acoustic transducing device comprises a piezoelectric body 3 positioned adjacent to and spaced from a conductive mesh 4 to which is applied an input signal, an electron beam 1 being directed at a selected area of the body 3 so as to generate surface waves in accordance with the signal applied to the mesh. The surface waves are detected by an output transducer B. The width of the selected area in the direction of wave propagation is of the order of #/4 (# being the acoustic wavelength). A plurality of electron beams may be provided with their respective areas separated by a distance which is variable to alter the frequency response of the device. The beams may be produced from a single wide beam by a mask, which may additionally serve as the mesh 4. A variable delay line may be provided by arranging for the beam 1 to be movable along the body 3 with respect to output transducer B. This arrangement may also be used to obtain pulse stretching, pulse compression and "time inversion" in which the beam moves along body 3 faster than the surface acoustic wave. If the beam deflection is a parabolic function of time a constant frequency burst may be converted into a chirp pulse.

Filed: 1919-12-31
Abstract: 137,313. Universelle Cigarettenmaschinen-Fabrik J. C. M³ller & Co. Dec. 24, 1915, [Convention date]. Cigarette-making machines.-In a machine for cutting cigarettes from a continuous rod, the reciprocatory motion of the cutters necessary to allow for the rate of feed of the rod is imparted to the cutter shaft alone, which is mounted in a rotating carriage which does not reciprocate and from which the shaft derives its rotary motion. The mass of the reciprocating parts is thus diminished, and a greater rate of feed becomes possible. In the arrangement shown in Fig. 3, the cutter shaft a is surrounded by a tubular member c provided with bearing-surfaces c<2> and carrying a driving-pulley. Rotation is communicated to the shaft a by flat bars g passing through the member c and engaging with flat surfaces f on the shaft a. In a modification, the bars g are replaced by rollers mounted on spindles carried by the member c.

Abstract: 601,646. Braces for personal wear. VEIT, J., and KENURE, J. F. Dec. 5, 1945, No. 32842. [Class 141] The shoulder straps of braces are formed from a single length of material doubled on itself to form a loop at the back adapted to receive a button link and held thus by a retaining member. As shown, the shoulder straps 3, 4 are formed from a strip of synthetic resin, e.g. polyvinyl chloride, or rubber, having longitudinal ribbing 30 on the under side. The retaining member consists of a sleeve 4a provided with a U- shaped notch 9 at the upper end of each side causing the shoulder straps to diverge. The free end of each shoulder strap is passed through slots 12, 13 in a runner 11 and bent at 19 to form a loop 25 through which a front button link passes. The end is then threaded through the slots 14, 15, the superposed portions of the strap being held by a sleeve 23. If desired, a similar runner may be employed in place of the sleeve 4a at the back. In a modification, a three-slot runner is threaded through a slot in each front button link 6, the shoulder strap being threaded through the slots and round the link, holding the link against longitudinal movement. Lateral projections may be provided at the bottom of the runner to retain it in the slot. In this case, a single slot runner may be employed, the strap ends being secured by, press studs so that the length of the web is adjustable. The slot in the link may be formed in an integral lug or web instead of through the link itself. Specification 601,647 is referred to.
