Title: Sampling liq. successively from tubes - carried in notches on rotating ring with control and drive assembly inside
IPC: G01N35/10
Filed: 1974-11-15
Abstract: An appts. for sampling liqs. contained in small tubes has a ring, with vertical nothces in which the tubes are carried, which rotates step-wise, and a sampling head with a suction pipe. As the ring rotates, the suction pipe is lowered successively into each tube. The driving motor and the suction head and its controls are housed in the inner part of the ring. The drive is by bevelled wheels engaging in the bevelled base of the ring. There are horizontal notches, in the walls of the vertical notches, which carry a wire supporting the sample tubes. A number of such nothces cater for sample tubes of different heights. The suction pipe dips into a rinsing vessel between each sampling. The sampling is controlled electrically. After the last tube has been sampled, the movement is stopped by a limit switch and an alarm is souded. The same alarm sounds if a tube is empty. Used partic. for taking blood samples, althrough it may be used for other applicns. The appts. occupies less space for the same number of sample tubes than existing appts.

Title: Three-by-three bit parity checking circuit - uses only four CMOS XOR gates for right data plus one parity bits
Inventor: GAUTIER YVES
IPC: G06F11/10
Filed: 1974-12-31
Abstract: The 3 x 3 bit parity checking circuit, for 8 bit blocks, has only four logic circuits each constructed using CMOS-techniques. These four CMOS logic circuits are identical XOR gates (21-24). Each of three of these gates is connected to 3 of the nine input bits (8 data bits + 1 parity bit (A9)). The outputs of these three gates are passed to the 3 inputs of the fourth gate. The advantage of this parity checking circuit lies in its using only four logic gates and in constructing these using CMOS elements.

Title: High pressure membrane pump - is driven via a crank piston and hydraulic oil supply (HU280775)
Inventor: TREFAN LASZLO
IPC: F04B43/067
Filed: 1975-07-16
Abstract: The membrane pump consists of a crank mechanism, a pistn which is driven by the crank and a membrane which closes the end of the cylinder in which the piston is mounted.

Title: Single oscillator microwave transceiver - has variable voltage oscillator feeding pH modulated signal to orthomode transducer
Inventor: AMOROSO SALVATORE JR
IPC: H04B1/40
Filed: 1975-08-19
Abstract: A variable voltage oscillator feeds an FM modulated signal to be transmitted to an orthomode transducer connected to a dual polarization antenna, another port of the orthomode transducer feeding received FM signals to a single ended mixer, the output of which is passed through an FM receiver. The orthomode transducer leaks a portion of the transmitted wave to the single ended mixer for use in lieu of a local oscillator, thereby limiting the requirements to a single microwave oscillator. The output of the FM receiver is applied to a cancellation circuit where the transmitter modulation is cancelled from the FM receiver output in response to delayed transmitter input signals.

Title: Asymmetric ethers prepn from alcohols and olefins - in high yields used to improve octane ratings of fuels(BE-27.2.76)
IPC: C07C67/00
Filed: 1975-08-28
Abstract: Ethers, esp. asymmetric ethers are manufactured by reacting (a) a water-sol. alcohol and (b) an olefin or a water-insol. alcohol in the presence of an ion-exchange resin etherification catalyst to obtain a reaction mixture contg. unreacted water-sol. alcohol and the desired ether. This mixture is then contacted with water in the presence of a benzene hydrocarbon and the resulting aqs. phase containing the water-sol. alcohol is separated from the benzene hydrocarbon phase contg. the desired ether free from water-sol. alcohol. The ethers are obtained in high yields, i.e. :80%. They can be separated from the benzene-hydrocarbon, but advantageously can be used as their solns. in the benzene hydrocarbon for direct addition to fuels to improve their octane ratings.

Title: Synchronised pneumatic drive for vehicle doors - has flexible incompressible enclosed system formed by two hydraulic cylinders
IPC: F15B11/22
Filed: 1976-11-05
Abstract: A synchronised pneumatic drive is especially for moving vehicle doors for opening and closing. A flexible, incompressible, enclosed transmission system is fitted to the pneumatic double acting drive on the load side. Specifically, there are independent, individual drives and the transmission system is formed by at least two hydraulic cylinders. The cylinder outlet of one cylinder is connected with the inlet of the next cylinder and vice versa to form a closed system. More specifically, the number of the individual drives is less than the number of the cylinders of the transmission system. The cylinders of the transmission system also serve as auxiliary drives. With several individual drives, only the first individual drive is acted upon pneumatically for the one direction and the last individual drive is acted upon pneumatically for the other direction.

Title: Appts. for measuring viscosity of coagulating liq. - comprises oscillating probe carrying inductive displacement detector
IPC: G01N33/49
Filed: 1976-11-16
Abstract: The appts. is intended for measuring parametric values of a coagulatable liq. A sample of the liq. is placed in a reservoir (10) into which a probe (22) is immersible. The probe (22) is appended to a vertical torsion bar (23) by the intermediary of a stiff rod (24). When the probe is lowered into the sample (11) a reciprocal oscillation about the torsion bar axis is imported to the probe. In order to measure successive oscillation, an inductive detector is mounted on the rod (24) from which signals are derived which can be electronically processed to yield the desired parametric valves.
