Abstract: 1514967 Piezoelectric transducers MURATA MFG CO Ltd 24 Oct 1975 [8 Nov 1974 21 Nov 1974] 43808/75 Heading H4J A piezoelectric transducer for transmitting or receiving ultrasonic waves comprises a base-plate 1 (Fig. 1) having a cylindrical supporting frame 2. One side of a piezoelectric bimorph 6 is secured to the supporting frame 2 by an elastic organic binder and a resonator 8 formed of synthetic resin is attached to the central region of the other side of the bimorph 6. The resonator 8 is a frustum of a cone, of a square pyramid (Fig. 4a, not shown) or a hexagonal pyramid (Fig. 4b, not shown). The cylindrical supporting frame 2 has a diameter equal to the diameter of a nodal circle developed at a predetermined resonant frequency of the transducer. A casing 9, preferably cylindrical, protects the bimorph 6. The resonator 8 may be of A.B.S. or polycarbonate resin. The base-plate 1 is of synthetic resin or other insulating material. The frame 2 may be separate from but attached to the baseplate 1 or the two may be integrally moulded. A metal shield plate 4 is provided. The piezoelectric bimorph 6 is square and is of ceramic. In a first alternative embodiment (Fig. 5, not shown) a piezoelectric bimorph disc has a resonator (11) in the form of a frustum of a cone, the small base portion being recessed. In a second alternative embodiment (Fig. 6, not shown) the resonator (13) is in the form of a cone having an axial aperture (14). The transducer may be used in remote control of a T.V. set.

Title: Rotary percussive apparatus
IPC: B25D16/00
Filed: 1976-10-22
Abstract: 1536738 Chucks ROBERT BOSCH GmbH 22 Oct 1976 [14 Nov 1975] 44049/76 Heading B3B [Also in Division B4] A rotary-percussive drill comprises at least one radially movable locking member 8 which engages a recess 7, in the shaft 5 of a drill tool 6 to limit axial displacement of the tool and at least one elongate driving member 11 which engages a drive receiving groove 9 in tool shaft 6 to transmit torque to tool 5, the sides of groove 9 having radial blanks. The locking member(s) 8 may be a sphere or cylinder. Drive receiving grooves (9) are parallel to the tool axis. Locking groove(s) 7 may also be parallel to the tool axis and may occupy the same portion of the length of the shank as groove (9). The one groove (19, Figs 3, 4, not shown) may be diagonally opposite the one recess 7. Alternatively two drive grooves may be on a diagonal making an angle of 45 to 90 degrees with a diagonal on which lie two locking recesses. An angle of less than 90 degrees (Fig. 11, not shown), provides an increased margin for wear at the torque transmitting sides of the grooves and so maximises the life of the tool. The edges between the sides (20, Fig. 9, not shown), of the drive groove(s) (19) and the circumferential surface of the tool shank may be bevelled. The bevels (21) may be flat or concave. Two drive grooves may be adjacent, the tooth-like separating projection (42, Fig. 10, not shown), being shorter than the outer sides of the two grooves to minimise their total width. The locking recess may be circumferential of shank 6 (Figs 5-8, not shown).

Abstract: 443,250. Counting and indicating apparatus. CONTROLOGRAPH (LONDON), Ltd., 10, Charles Street, St. James's Square, London, and JAMAUX, R., 116, Boulevard de Versailles, Suresnes, Seine, France. Sept. 5, 1934, Nos. 25541 /34 and 24767 /35. [Classes 106 (i) and 106 (iv)] Apparatus for indicating both the duration of the time of operation of a machine and also the number of revolutions or oscillations of a part of the machine comprises a chronometric mechanism, a counting mechanism and a driving mechanism comprising a pendulum moved by gravity relative to a member carried by a moving part of the machine. In one form, Figs. 1 and 3, an oscillating part 5 of a machine carries a pendulum 1 which drives a ratchet wheel 8 by means of a pawl 10. The wheel 8, Fig. 3; winds up the spring 25 of a known chronometric mechanism 27, 28. The wheel 8 when moved also releases a stop in the chronometric mechanism which allows the spring 25 to drive a counter 29 at a rate controlled by an escapement or equivalent device. The counter 29 thus indicates the duration of the time of operation of the machine. Pawls 13, 131 on the pendulum 1 drive a ratchet wheel 12 connected to a counter which shows the total number of oscillations. In a modification, Fig. 2, the pendulum 1 and a pinion 19 are secured to a shaft 6 on which is pivoted a cradle 16 carrying pinions 18, 18<1>. Shafts 20, 21 having pinions 22, 23 are journalled in the machine part 5. When this part rotates or oscillates about the shaft 6, the pinions 18, 20 or 181, 23 are brought into contact and then the shafts 20, 21 are driven by the action of the other pinions rotating as planet pinions about the sun pinion 19 held stationary by the pendulum 1. The shafts 20, 21 are connected to the chronometric mechanism and to the counter respectively. These shafts are driven in the same direction for either direction of rotation of the part 5.

Abstract: 1,192,417. Elevated railways. SAFEGETRANSPORT. 2 Oct., 1967 [10 April, 1967], No. 44743/67. Heading B7L. An overhead railway system (to operate at speeds of 125 m.p.h. and above) comprises a track 1, Figs. 1 and 2, supported by pylons and having spaced surfaces 11, 12 to support pneumatically-tyred propelling wheels 13 of bogie trucks 6 having suspension members 5 carrying a vehicle body therebelow, the trucks also having pneumatically-tyred guide wheels 15 engaging the inner vertical side walls of the track 1.

Abstract: 1535563 Television RANK ORGANISATION Ltd 26 Oct 1977 [28 Oct 1976] 44819/76 Heading H4F Flying spot telecine apparatus operating according to the 625/50 television standard wherein the film is continuously driven at 25 film frames per second, is characterized in that each film frame is scanned with 625 lines sequentially but at a line frequency greater than the standard line frequency, a vertical scan deflection being applied to the flying spot beam which is greater than would be necessary if the frame were scanned sequentially at the standard line frequency. Thus a larger surface area of the face plate of the flying spot CRT is used resulting in a reduced current density on the face plate and therefore increased tube life. The resulting video signal is converted into interlaced form and to the standard line frequency, e.g. using a store, separate colour signals being also encoded into a single signal.

Abstract: 1312103 Fuel cells COMPAGNIE GENERALE d'ELECTRICITE 24 Sept 1970 [29 Sept 1969] 45663/70 Heading H1B A fuel cell operating with an alkaline electrolyte, e.g. KOH, and a hydrocarbon fuel, e.g. methanol, and using air to assist combustion, is constructed so that the electrolyte is decarbonated during its passage through the cell by causing carbon dioxide to be evolved and removed in gaseous form. The carbon dioxide is evolved by reducing the pH value of the electrolyte in a central compartment 13 of the cell to a value of about 8, the pH value of the electrolyte in the compartments 12, 14 adjacent the cathode 1 and anode 2 remaining substantially constant. The compartments 12, 13, 14 are formed by cathode 1, anode 2, cationic membrane 3 and anionic membrane 4. The KOH electrolyte from cathode compartment 12 is supplied through a mixer 7 together with methanol from a duct 5, to the anode compartment 14. A pipe 9 supplies partially carbonated electrolyte from the compartment 14 to the central compartment 13. During its passage to the top of the compartment 13 the KOH decreases in strength due to the migration of K and OH ions to the cathode and anode respectively causing a continuous reduction in the pH value until a value of about 8 is reached when CO 2  is evolved and removed through pipe 10. A pipe 11 transfers water from the top of compartment 13 to the compartment 12 and a pipe 15 may circulate electrolyte through the latter compartment.
