Title: Rotary piston engine with trochoidal rotor - uses pinion meshing with internally toothed wheel to guide rotor
IPC: F01C17/00
Filed: 1975-06-11
Abstract: The trochoidal rotor (4) is mounted on a casing consisting of a central portion (6) with end covers (52, 62). The rotor (4) runs on a needle roller bearing (20) mounted on the crankpin (112) of the crankshaft (30) which runs in the ball bearing (24). The rotor (4) has an integrally formed pinion (26) which meshes with an internally toothed wheel (28) which is rigidly attached to the casing. A shaft (110) which is an extension of the piston (26) and co-axial with it, runs in a needle roller bearing (18) which is fitted in an eccentric (14) running in the ball-bearing (22). The eccentric (14) thus forms a counter-balance weight for the rotor (4). This design simplifies the cooling and lubrication of a rotary engine.

Patent FR-2327092-A1 (FR)
IPC: B22F3/12
Filed: 1976-10-06
Abstract: The quantity of damping liquid intended for the plate cylinder (8) of an offset printing machine is to be able to be metered very precisely. The brush roller (5) now no longer takes the damping liquid directly from the dipping roller (2) - there is a spacing between the brush roller and the dipping roller - but removes the damping liquid from a dish (4) into which the damping liquid has been introduced, metered precisely by the dipping roller with the aid of adjustable scrapers (9, 13). The brush roller (5) wipes all the liquid from the dish (4) and conveys this liquid (6, 7) onto the plate cylinder (8). At least one of the scrapers (9, 13) can be adjusted very precisely. Such a precise, desired metering of the quantity of damping liquid can be achieved that this brush unit is also suitable for jobbing presses.

Title: Radar aerial with spiral elements - has multi arm sections with asymmetrical windings compressed in centre for frequency independence
IPC: H01Q11/04
Filed: 1977-02-03
Abstract: The frequency and phase unaffected aerial characteristics are used for mono-pulse tracking systems. The design is based on multi-arm spiral elements terminating on the inside which acts as the centre of the aerial. The asymmetry of the elements is obtained by compression of the winding on one side, while the spiral may be either logarithmic or archimedean. The spirals (12/14) are deposited on a dielectric using photoetching or other known techniques, and the centres of the elements are aligned along the diagonal (20). The number of windings is determined by the frequency range and is given by a formula together with the data for spacings. The terminals (16/18) are fed from a compensating network so that the signals exhibit a phase difference of 180 deg.

Title: DC voltage summing circuit for different reference potentials - consists of isolating circuits and impedance converter
IPC: G06G7/14
Filed: 1977-04-25
Abstract: The application is principally to control or measuring circuits where it is necessary to sum dc voltages having differing reference potentials (U1, U2). The desired end is achieved by applying each voltage to a dc isolating circuit (1, 2) and feeding the isolator output put (10, 7, 8, 9), after summing, to an impedance converting amplifier (11). The output from this amplifier can then be used in the measuring or control circuit as a proportional value. The isolating circuits (1, 2) are typically composed of operational amplifiers of conventional design, and the impedance converter is a similar device. The resulting compact circuit is sparing in the use of components.

Title: Transportable thickening machine for polluted water - with mixing tanks for fillers and setting agents to produce semi-solid prod.
IPC: C02F1/52
Filed: 1977-05-05
Abstract: Mobile treatment plant for polluted waters converts them into a semi-solid prodn., by the addn. of an active agent to allow of their easy transport to the disposal site. The plant is mounted on the chassis of a road vehicle and comprises a tank with a variable-speed mixer where a pulverulent active or inert thickening agent is introduced by the dosing unit; the mixer is filled by the pump from a storage cistern. The treated liq. is taken by pump to the second mixing tank, which may be inclined, where it receives the necessary amt. of a setting agent from the variable dosing pump. The spiral screw, driven by the motor, transfers the mixt. during its semi-solidification to the outside of the machine. The final prod. has a consistency that enables it to be manipulated with ease. The water can be treated near its point of prodn., transported and delivered in the semi-solid condition from the plant on the storage site.

Title: Quartz controlled watch adjusting device - compares local oscillator frequency with that of atomic clock standard radio transmission
IPC: G04D7/12
Filed: 1977-11-23
Abstract: The adjustment of quartz oscillator controlled watches is by comparison with an atomic clock. The method removes the need for a day-by-day check on such watches in order to provide correction. The atomic clock is normally that governing a standard radio emission. This is compared with a sensor, usually capacitive with the watch facing, via a phase and frequency comparator providing a visual output at a moving coil meter. The transducer output is initially amplified, the radio source frequency being reduced using a local oscillator and mixer before being fed to the logic gate based comparator.

Title: Gear tooth design based on standard pitch - uses non-involute tooth form to increase max. load capacity
IPC: F16H55/08
Filed: 1977-11-30
Abstract: With gears having involute form teeth there is a critical number of teeth for which the load capacity is a max. To avoid this restriction on the number of teeth in a gear it is proposed to use a tooth form which departs from a true involute. The gear teeth (12, 14) are so formed that the radii of curvature (r1, r2) are in each case less than the radius of curvature of the true involute form at the point of contact (P) of teeth of the same size and pressure angle. The addendum of the tooth is greater than 1.1 times the tooth module, the total height is greater than 2.6 times the module and the angular pitch is not greater than 10 deg.
