Title: Improvements in or relating to transducer coupling circuit arrangements
Inventor: MORTLEY WILFRID SINDEN
IPC: H03H9/30
Filed: 1958-06-04
Abstract: 856,070. Circuits for electro-mechanical transducers. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. March 2, 1959 [June 4, 1958], No. 17909/58. Class 40 (4). A transducer which is excited by two carrier frequencies is balanced in a bridge circuit resonant at both of the frequencies and such as to supply the carrier frequencies to, or be supplied to the carrier frequencies by, two signal circuits which are decoupled from each other. The arrangement is applied to the quartz crystal or barium titanate drive or pick-up for an ultrasonic delay line, the carrier frequencies being modulated by low frequencies which by themselves would be prohibitively attenuated. As shown in Fig. 1, the frequencies f1, f2 are fed across the diagonals of a bridge having inductors L1 and a piezoelectric transducer Ct balanced against an equal capacitor Co. The two resonances are those with current modes in push-pull and pushpush across the diagonal with inductor L2. Resistors R1 and R2 provide bandwidth and may be constituted by inherent resistance such as that of the signal sources. Transformer coupling of the signal sources may be used, as in Fig. 4. In place of coupling over transformer T3 third windings connected in opposition on transformers T1 and T2 may be used for frequency f2, or this may be coupled by an auto-transformer as shown in Fig. 7, where the transformers T1 and T2 are shown replaced by a single centre-tapped transformer. Capacitor Co may be damped to match the transducer Ct.

Filed: 1946-06-14
Abstract: 613,186. Unloading and treating fish; endless conveyers. MOORE, T. June 14, 1946, No. 17945. [Class 78 (i)] A work bench for handling fish comprises an elevated runway for transportable containers, a shoot down which fish are discharged from the containers, and a filleting or like table at the bottom of the shoot to receive the fish, said table being provided with openings through which fillets, offals and the like may be dropped on to conveyer means below the table and transported to separate collecting means. In the embodiment shown, the fish are discharged from trucks 1 on to a shoot 12 leading to a water trough 14 in a filleting table 15 and after treatment, the fillets and offals are dropped through openings 19, 20 in the table to be led by shoots 21, 22 respectively to the top and bottom runs 23, 24 of a belt conveyer. The bottom run 24 of the conveyer extends along a trough 25 which prevents the offals falling off and one side wall of this trough is extended at one end across the belt to sweep the offals off the belt. The upper run 23 discharges the fillets into weighing bins or other collecting devices. The delivery of fish into the trough 14 is controlled by a grill 16. Preferably a single conveyer belt may serve a line of filleting stations formed along one table and this structure may be duplicated, the two sections being arranged back-to-back and served by a common truck runway.

Title: Damper for use in motor vehicle suspension systems

Filed: 1970-01-06
Abstract: 1299340 Dampers FORD MOTOR CO Ltd 6 Jan 1970 18008/72 Divided out of 1298921 Heading F2S A vehicle damper has the following features: (a) jounce movement (in direction J) of an input member (e.g. a lever 36 connected to two pistons 34, 35) relative to a control member (e.g. cylinder 30) causes liquid to flow only through a jounce passage 40 in the control member; (b) rebound movement (in direction R) of the input member relative to the control member causes liquid to flow only through a rebound passage 41 in the control member; (c) a valve member 45 restricts flow in both the jounce 40 and rebound 41 passages; (d) the valve member 45 is movable relative to the control member 30; (e) the valve member 45 is connected to the input member 36 through spring means 51 so that the valve member 45 is urged in one direction (downwards) upon movement of the input member 36 in the jounce direction and in the opposite direction (upwards) upon movement of the input member 36 in the rebound direction; (f) movement of the valve member 45 relative to the control member 30 is damped (by orifice 58); and (g) movement of the valve member 45 in the one direction (downwards) makes the jounce passage 40 more restricted and the rebound passage 41 less restricted. The rate of the spring 51 and the damping of the movement of the valve member 45 are chosen so that movement of the input member 36 relative to the control member 30 at a frequency above about 5Hz (corresponding to wheel movements) produces insufficient response at the valve member to change the restrictions in the jounce and rebound passages 40, 41, and movement of the input member 36 at frequencies below about 2Hz (corresponding to body movements) produces corresponding movement of the valve member sufficient to change the restrictions in the jounce and rebound passages 40, 41. The valve member 45 has an intermediate position (shown) in which the restrictions in the jounce and rebound directions are approximately equal. Any change in the vehicle loading produces a constant displacement of the valve member from its intermediate position thereby affecting the damping. If this is not desired, a valve body 44 surrounding the valve member 45 is made movable with respect to a valve cylinder 33 (Fig. 2, not shown) and connected to the input member by a second spring so as to respond to very low frequency movements (corresponding to change in vehicle load). Instead of being lever-type, the damper may be telescopic.

Abstract: 434,152. Cutting-appliances. ALLABY, J. H., 106, Newmarket Road, Waterloo, Ashtonunder-Lyne. June 20, 1934, No. 18195. [Class 31 (ii)] A tool for trimming the edges of sheet material, e.g. wallpaper, leather, or fabric, comprises a compressible handle carrying a razor blade trimming edge and a support for the sheet ; compression of the handle causes the trimming edge to pass through the sheet, which is then trimmed by relative movement of the tool and the sheet. As shown, the handle consists of a U-shaped resilient metal member 7, 8, of which one leg 7 has an inclined extension 9 to support a 3-holed razor blade 1, and the other leg 8 carries rollers 18, 19 between which the blade 13 engages when the legs are pressed together. In one form, Figs. 1 and 2, the sheet is guided by a channel member 20 adjustably secured to the leg 7 by a pin 24, slot 25, and nut 23. In another form, Fig. 6, the guide is dispensed with, and a guard member 29, 30 is provided against the blade 13.

Abstract: 1,154,022. Ornamenting-printing embossing surfaces. E. A. MAGID. 26 April, 1966 [26 April, 1965], No. 18202/66. Headings B6C and B6G. A flexible decorative sheeting (by which is meant single or multiple webs, the or at least one of which, is made of a thermoplastics material) has depressed regions formed by electronic embossing and having material printed only on the areas of the sheeting which are not depressed. By electronic embossing it is meant that-the material of the sheeting is dielectrically heated by electronic equipment during the embossing process. As described, the printing material is applied by passing the sheeting between a backing roller and a printing roller, the spacing between the rollers being such as to prevent compression of the sheeting. The printing may be in a contrasting colour and may be on a-pattern or cover the whole of the raised area. When two webs are used a filler is interposed, this being compressed to negligible thickness in the embossed areas.

Abstract: 751,299. Pressure-relieving devices for fluids; valves. CHENILLAT, M. R. June 22, 1954, No. 18258/54. Class 135. A device for damping water hammer in a hydraulic line comprises a tube 2 terminating in a convergent nozzle 10 through which the liquid passes, an annular damping chamber 4 around the tube and terminating in a convergent-divergent nozzle facing the nozzle 10, and the tube communicates with the chamber through the gap between the two nozzles. The pressure produced by a water hammer shock is absorbed by the air cushion in chamber 4. When normal flow takes place, air is drawn in through a non-return valve 12 to replenish the cushion as a suction is produced in the chamber due to the venturi effect at 11. In modifications, the pressure due to the water hammer is applied to a spring-loaded piston slidable over the tube 2.
