Title: Reinforced concrete sawtooth hangar roof sections - comprise two obtuse angled panels with centre of gravity above centre thrust point
IPC: E04B7/12
Filed: 1969-04-16
Abstract: The sawtooth roof for hangar-type buildings is made up from reinforced concrete structural elements in folded shape, and intervening glass surfaces. It is designed for easy erection and to enable wide areas to be spanned. The concrete elements each consist of only two panels of different width, set at an obtuse angle to each other. The thickness of these is such that the centre of gravity of each concrete element is sited vertically above the centre point of thrust. The elements may incorporate only stressing wires led in a straight line, and corner strengthening may be provided where the two panels come together. There are virtually no torsional forces resulting from inherent weight.

Title: Brush for prevention of electrostatic build up - is for electrostatic discharge and dedusting during playing
IPC: G11B3/58
Filed: 1971-03-30
Abstract: Static build up due to rubbing on records when placing them into or removing them from covers causes crackling noises when the discharge takes place during playing especially when conducting pins are used. To prevent the build up of static electricity on records and to discharge it soft conducting brushes are used which are connected to the earth point of the record player. The conducting arrangement (9, 10) can be partially or entirely made of metal and is mounted on the metallic carrier arm (7) which is connected to earth via cable (14) pin (15) and connection (17). The brush (9) can be made of plastic or natural fibres interwoven with metallic threads and is connected to an electricity conducting holder (10).

Title: Piezoelectric igniter for manually operated ram - has guided contact piece for extending life of sintered piezoelectric element
IPC: E02D3/061
Filed: 1972-01-26
Abstract: The piezoelectric igniter mechanism is designed to prevent inclined impacts on the piezoelectric element even after longer operating times. The life of the sintered piezoelectric element is prolonged if normal impacts to the element contact face can be guaranteed. The piezoelectric element is held in a cylindrical sleeve. A metallic plunger is guided in a coaxial bore and the plastics actuating handle is kept in the rest position by springs. On actuation the handle is pushed down and the head of its central metallic bolt contacts the plunger which in turn impinges normally on the piezoelectric element whose upper end is earthed and the lower end transmits a high voltage pulse to the sparking plug.

Title: Aircraft wheels rotating equipment to aid landing - uses hydraulic unit to store wheel energy after take=off and to feed it back before landing
IPC: B64C25/40
Filed: 1972-01-19
Abstract: The equipment for rotating aircraft undercarriage wheels (3) before landing comprises a hydraulic pump/motor unit (24) operating in conjunction with a pressure reservoir (25). As soon as the wheels leave the ground during takeoff a toothed wheel drive to the unit is clutched in and the rotational energy of the wheels is used to pump up the pressure reservoir. Valves in the system control the flow. In preparation for landing these valves are reset so that the stored pressure energy drives the hydraulic unit as a motor in the same direction to accelerate the wheels. A backup driving unit is fitted in case the stored energy is insufficient.

Abstract: A steering wheel having an air bag device which includes a ring portion, a boss portion, a bracket, a spoke and an air bag device. The boss portion has a boss and a boss plate extending laterally from the boss periphery. A bracket made of plastically deformable metal has a supporting portion inclined outwardly in opposite directions toward the ring portion. The air bag device is held at a predetermined distance from the boss plate by the bracket and includes a bag holder made of plastically deformable metal and having connecting portions inclined at the same angle as the supporting portions of the bracket. By providing supporting portions inclined in opposite directions, the steering wheel of the present invention can absorb impact energy not only by inflation of the air bag device but also by deformation of the supporting portions due to rotation of the air bag device during impact.
Patent JP-S5946463-B2 (JP)
IPC: H03F3/20
Filed: 1980-02-08
Abstract: An amplifier includes first and second switches coupled at a junction to form a series circuit. The series circuit is serially coupled with an inductor across a source of energizing potential. A capacitor couples the junction between the switches to a load. The switches conduct alternately under the control of a duty cycle modulator. The duty cycle modulation tends to vary the amplitude of the two opposite-polarity portions of the signal appearing across the load. A clamp is coupled to the junction of the series switch circuit and the inductor. The clamp operates during a first of the two alternate switch conduction intervals to clamp the voltage across the inductor at a fixed value. Since a direct voltage cannot be established across an inductor, the voltage across the inductor during the second switch conduction interval is established by the clamp voltage and the duty cycle, and varies with duty cycle. The amplitude of the signal at the junction of the two switches varies with duty cycle variations in such a manner as to maintain the signal of one polarity across the load at a constant amplitude.

Abstract: Disclosed is a method for stopping and starting a reactor equipped with a heat exchanger, a catalyst settler, a catalyst filter and the like, which method is suitable for use in a process for the preparation of acrylamide by reacting acrylonitrile with water in the presence of a metallic copper-based catalyst used as a suspended bed. According to this method, various undesired phenomena which may occur at the beginning of operation can be prevented by discharging the metallic copper-based catalyst until the total amount of metallic copper and copper oxides present in the catalyst remaining in the reactor is not greater than a certain level based on the amount of metallic copper catalyst used at the beginning of the operation, or by discharging the catalyst until the amount of copper oxides is not greater than a certain level and then establishing an inert environment within the reactor.

Abstract: Implantable articles, such as bone prostheses, are prepared by casting techniques and have incorporated therein fluid communicating passageways. The internal fluid communicating passageways convey synovial fluid from a joint space to the articulation surface of an artificial joint. The presence of synovial fluid at the articulation surface provides sufficient lubricity to the joint and enables artificial joints to utilize metal/metal, metal/ceramic, and ceramic/ceramic articulation couples without the need for a low friction polymeric lining material. Accordingly, artificial joint components formed according to the present invention are less likely to develop wear debris. The implantable articles are formed by a casting process from casting molds that are prepared using a three dimensional printing technique. <IMAGE>

IPC: F16D3/48
Filed: 1984-04-06
Abstract: In a compensating coupling having flanges (1, 1', 3) connected with each other by a plurality of bolts (2), one of the flanges is connected with a rotating drive member and the other with a rotating driven member. The bolts (2) consist of a journal (8') fastened to one of the two flanges (1, 1', 3) and a sleeve (15) fastened to the other flange (1, 1', 3). The sleeve is supported on the journal by an axially vaulted surface formed on a spherical ring (20) displaceably located on the journal. A high torque may be transmitted by the coupling even when the drive shaft is tilted with respect to the driven shaft by virtue of the fact that the spherical ring is supported in an axially displaceable manner with respect to the sleeve and that at least one compression spring (13) biases the spherical ring back into its initial position.

Abstract: In a prophylactic method for cleaning and disinfecting a contact lens, the lens is contacted for an extended period, typically up to 10 hours, for example 5 to 10 hours, with a solution containing hydrogen peroxide. The contacting is effected in the presence of a solid sustained release composition which slowly liberates a peroxide inactivator and which maintains its integrity over the extended period. The solid composition liberates sufficient peroxide inactivator such that substantially no peroxide remains in contact with the lens at the end of the extended period. The lens may then be contacted with a contact lens wetting or comfort solution before insertion into the eye.
