Title: Antibiotic rifamycinyl methimino pyrimdines - e.g. 2,4-bis-(3-rifamycinyl (SV) methimino) 5-(3,4,5-trimethoxybenzyl) pyrimidine
IPC: C07D498/08
Filed: 1975-01-16
Abstract: Cpds. of formula (I) are new (where R is 1-4 substits chosen from lower alkyl, lower alkoxy, NO2 and halogen; R' and R" are each rifamycin SV or its 16,17,18,19,28,29-hexahydro deriv. bonded by the C in posn. 3, or the gp. -N=CH-R" may be replaced by -NH2). (I) have antibiotic activity. Rifamycin SV has excellent activity against Gram positive organisms, e.g. Staphylococcus, Streptococcus and Pneumococcus spp., and is used in treatment of biliary infections, local treatment of the tubercular processes etc. It also inhibits DNA-polymerases and is thus useful in treatment of viral tumours. Rifamycin SV is absorbed only with difficulty in the digestive tract and is eliminated rapidly via biliary routes and is thus pref. used as an iminomethyl deriv. The 2,4-diamino-5-benzyl pyrimidines are known to have antibacterial and antimalarial props.

Title: Valve for reciprocating metering pumps - has double valve using two sizes of ball in conical duct
Inventor: LOMBARD DIDIER
IPC: F16K15/04
Filed: 1975-10-09
Abstract: Metering pumps frequently use a double ball non-return valve for both inlet and delivery valves. Such valves require accurate guiding of the ball in order to ensure its proper seating. To achieve this degree of accuracy results in high manufacturing costs. To obviate this difficulty in inlet and outlet, valve housings (1) (1') are provided with conical passages (a) to suit balls of two different diameters (2) (2') and (3) (3'). The valve housings are screwed in to the cylinder (4) which houses the piston (5). The conical passage allows the balls to find their own seating position without the need for accurate machining of the bore or the need for a valve guide.

Title: Ribbon edge stretching unit - has a disc powered by an electro-motor through an induction motor to give an adjustable torque
IPC: D06C3/02
Filed: 1975-11-28
Abstract: Appts. for stretching the edges of fabric ribbons, before passing to the stentor chains of a spreader, comprises a drawing disc powered by an independent electro-motor through an induction coupling. The design ensures that the edges are spread out under control, without damaging sensitive fabrics, without causing the drawing disc to slip. Specif., the electro-motor drives the induction coupling at a constant speed. According to the adjustable current, the induction coupling transmits a portion of the torque to the drawing disc through toothed wheels. The ribbon matl. is clamped between the drawing disc and a continuous belting so that there is no slipping, the constant torque ensuring that the drawing disc applies a constant pull on the edges of the ribbon. The position of the ribbon edge is monitored, and the degree of tension applied to the edges is controlled by the current applied to the induction doupling.

Title: Magnetic thickness gauges calibration - uses nickel test plate of known thickness providing calibration reading for permanent magnet probe
IPC: G01B7/06
Filed: 1976-12-27
Abstract: The thickness gauge test apparatus is suitable for use with instruments designed to measure coatings on ferromagnetic substrates. The permanent magnet probe of the gauge to be calibrated (5) is first fully magnetised. The spring-loaded magnet is then drawn across the surface of a precision test surface of known properties (6). A plate of pure nickel with a magnetic saturation Js=0,62 T is used. For an instrument with a thickness measuring range of 0...1000 mum, a nickel test plate of 1 mm thickness provides a calibration point equivalent to 65 mum and a plate 0.1 mm thick an equivalent of 900 mum. The magnetic probe of the instrument is now progressively demagnetised until the pointer reading reduces from infinity (8) to the calibration point (b) related to the nickel test plate in use. At this point the instrument is calibrated.

Title: Duration regulator for temp. dependent heated metal flow process - uses temp. representing voltages which are compared, and closes supply circuit to sync. motor which controls warning system
Inventor: DROUZY MICHEL
IPC: B22D17/32
Filed: 1977-04-08
Abstract: The system uses a pyrometer which measures the temp. e.g. in foundry mould. The pyrometer furnishes an electrical voltage, which is a function of temp. to a comparator. The comparator compares the pyrometer voltage with a reference voltage. The output signal from the comparator is proportional to the voltage difference and therefore to temp. difference. The comparators output closes via a wave shaping circuit and a relay a switch in a supply circuit feeding a synchronous - motor. The motor after completing a given number of revolutions actuates a warning system. The duration of closure of the switch and therefore the duration during which the motor rotates depends upon the output signal of the comparator.

Title: Stabilised supply for antiskid traction control - uses galvanic isolation element e.g. transformer to eliminate interfering transients
IPC: B60L3/10
Filed: 1977-04-14
Abstract: The electric traction control incorporates a non-skid circuit with rectifier, monitoring stage, voltage stabilised supply and output amplifier. In order to eliminate transients, which lead to poor control, a galvanic isolator is included. This can be a voltage transformer or similar element. The capacitance between supply and control circuit remains at a steady level, while any losses through the normal isolators can vary with climatic conditions, making conventional circuit protection difficult. Earth conections on the battery side and additional earth connections on the control wiring have no effect o the protective function. If the coupling capacitances of the energy supply are small enough h.f. interferences are obviated so that a filter is no longer necessary.
