Title: Antibiotic - resistans streptococcus faecalis - for treatment and prophylaxis of digestive disturbances
IPC: A61K35/744
Filed: 1971-01-15
Abstract: An active lactic bacteria prepn. having multiple resistance to medicaments is produced by selecting a sulphonamide-resistant strain of Streptococcus faecalis by the substance-gradient agar method and successive transfer to media with sub-inhibiting concns. of Streptomycin, chloramphenicol, tetracycline, erythromycin and aminobenzylpenicillin (in that order), stabilising this strain by successive further cultivation in milk medium contg. the above-mentioned antibiotics, and, after cultivating the strain in a skim-milk medium, pulverising the culture by spray-drying. The selected S. faecalis strain is of use in the treatment and prophylaxis of epidemic digestive disturbances due to antibiotic-resistant dysentery bacteria, and has the advantage of retaining its effects in the presence of not only sulphonamides and the above-mentioned antibiotics but also numerous other antibiotics.

Title: Sieving wet sticky material without clogging sieve - using inclined surface with transverse bars, pref with vibration of sieve
IPC: B07B1/28
Filed: 1972-09-08
Abstract: Sorting granular, esp. moist and sticky materials according to their particle size, in which the material is fed onto an inclined surface of cords or rods extending transversely to the line of max. slope; the spacing between the rods exceeds the max. particle size to be sorted, and the material is moved during the sorting operation, pref. by vibrating the sieve, at such a speed that the particles below the predetermined sorting size just fall between the rods or cords, while those greater than that size just remain above them. As the material moves down the inclination of the sieve, it is divided into a number of fractions. The downward speed of movement of the material may be varied by the sieve having a convex or concave surface; the spacing between rods or cords may either decrease or increase progressively down the sieve. Typical applications include sieving of washed coal, sand, gravel or other wet and sticky minerals.

Title: Control system for retracting headlights - has time delay for operating-headlamp flashers to allow initial extension
IPC: B60Q1/05
Filed: 1974-10-08
Abstract: The headlamps are brought into the operating position by one or two electric motors operated by a switch and a coupled relay. The switch only has to be operated briefly so that the relay holds the motor current until the headlamp is fully open, after which the motor is dynamically braked by shorting its input lines to earth. To retract the lights the switch is briefly pushed in the other direction. To operated the flashers the switch is operate both ways in sequence and a time delay system ensures that the lights are fully extended and then flashed for a set period before being retracted.

Title: Railway wagon coupling system - measures distance required at siding, to estimate impact force
IPC: G01B7/14
Filed: 1975-05-28
Abstract: A railway siding uses a method of measuring the distance required to coupled a wagon to a train. A continuous section of the track is isolated from all traffic and the distance separating the rear wagon (9) from a reference point within this section is measured. The wagaon is then given a kinetic energy dependent on the distance measured so that it becomes hitched to the train with a known impact force. The distance measurement is made by transmitting a signal along one of the rails (6) of the isolated section of the siding to the reference point. The distance is found by measuring the time elapsed between transmission and reception of the signal. The wave train may be periodic to simplify signal reception. The signal may be ultrasonic radio, electromagnetic, longitudinal or transverse.

Title: Continuous monitoring of the concentration of complex solutions - by using selective electrodes immersed in a constant volume cell
Inventor: DENIS RENE
IPC: G01N27/416
Filed: 1975-11-27
Abstract: A continuous constant stream of soln. from the main flow is mixed with a fixed amt. of dilutant, e.g. de-ionised distilled water, and pumped to a constant vol. cell. A selective electrode for each solute, the concns. of which it is required to measure, protrudes into the cell and the ionisation concn. is fed to a pH meter. The pH meter gives out in turn, an analogous voltage "u" which is relayed to a calculator. This calculator, using the equation: calculates the concn. of the solute in the undiluted stream from the signal obtd. from the diluted flow, and transmits the value to a recorder. Used for continuous determination of concn. of ionised solutes in complex solns. esp. liq. streams from reactors, e.g. measurement of HBr in an aqs. soln. formed by hydrolysis of Ca Br2 to produce hydrogen. Gives accurate measurement within 2% error and the response time for the measurement is short and depends on the distance of the cell from the sample point. Allows continuous checks of solns. with no limit on the concn. of the solute in soln.

Title: Tape recorder recording level control - uses capacitor-resistor circuit to prevent abrupt changes at beginning of recording
IPC: H03G3/04
Filed: 1976-01-30
Abstract: Recording level control for tape recorders supplementing the normal level control by providing a gradual level transition at the start of recording rather than the abrupt start which otherwise occurs. The facility is intended to be optional in that it can be switched out of circuit. The technique uses a OR circuit which is switched into one of several possible circuit positions such that an extra bias level is imposed on, for example, the normal level control amplifier for the period of the CR time constant. The bias level supply is introduced by an extra switch associated with the start stop manual control.

Title: Impulse type hydraulic motor - has retracting vanes in guides in rotor arms worked by low pressure oil
IPC: F03C2/30
Filed: 1976-05-07
Abstract: The impulse type hydraulic slot speed motor is capable of developing very high power and of operating in a closed circuit, part of its power being used to drive its pumps. It has circular chambers round the periphery of the stator and in which there work retracting vanes, under the action of low-pressure oil. The vanes are accommodated in lever arms fixed to the rotor shaft and impart to the latter a rotary movement as the result of the high pressure oil in the circular chambers. The slides in which the vanes work can be at right angles to the rotor shaft, the vanes being driven by the high pressure oil in the chambers until they uncover the outlet ports.
