Filed: 1930-02-18
Abstract: 341,752. Road-traffic control signals. BATHGATE, J., 19A, Goldenacre Terrace, Edinburgh. Feb. 18, 1930, No. 5368. [Class 118 (ii).] Traffic control signalling apparatus for four-way traffic comprises an octagonal lantern adapted to display opposite duplicated signals on an inner cylinder g<1> which is rotated intermittently by electromagnets controlled by an oscillating timing switch g<2>, a gong being sounded at each change of signal. Manual control is also provided. The cylinder g<1> is secured to a spindle a carrying discs b<1>. When the switch member g<2> is tilted, four electromagnets c<1> are energized and by their attraction of iron pieces d rotate discs b<1> one-eighth of a circle and depress the member g<2> by means of rollers j<2> riding on a cam j. This causes liquid to flow from one chamber h<1> on the member g<2> to another by means of tubes regulated by check valves h<2>. The member g<2>, being thus tilted farther, tilts over a mercury container k and so energizes four other electromagnets, continuing the rotation of the discs b<1> and the tilting of the member g<2>. Between the breaking and making of the contacts operating the electromagnets a further switch is automatically operated to actuate the gong signal. The member g<2> may also be tilted at will by means of a hand-operated master switch, so as to hold the signal stationary for any desired period.

Title: Device for measuring the dose of ultraviolet radiation in the erythema-effective range
IPC: A61N5/00
Filed: 1974-02-06
Abstract: 1454620 Measuring UV dose photo-electrically BIVIATOR SA 6 Feb 1974 [18 Sept 1973] 05461/74 Heading G1A A U.V. detector produces a pulse train output which can be integrated over a period of time by a counter to measure total dose. In Fig. 3 the circuit of a monitor for a person undergoing radiation, e.g. U.V. therapy or sun bathing, is shown. A Photoresistor FR acts as a U.V. sensor and controls the pulse repetition rate of a UJT transistor oscillator Tr 1 . The pulses are inverted at Tr 2  and counted at Z. A de-coder D converts the binary count into an analogue signal to drive oscillator O and alarm J. The switches S 2 , S 3  allow the de-coder to be set so that the oscillator O is triggered only when a predetermined dose has been counted. Switch S 2  is set according to the sensitivity of human skin to U.V., and switch S 3  is set according to the type of U.V. source. Another switch S 1  varies the basic pulse repetition rate, and is set according to the number of days for which previous exposure to U.V. has occured. The photo-resistor is preceded by a filter passing only the UV-B range (280- 315nm) and a window; both these may be facetted to increase the angle over which radiation is measurable. A check may be made on the circuit by turning S 1  to short out FR and to connect only C 1 ; this produces a very high pulse rate which rapidly fills the counter and hence drives oscillator O and the alarm.

Filed: 1947-02-26
Abstract: 629,009. Resistance and capacitance measurements. BURKETT, R. H. W., and WELWYN ELECTRICAL LABORATORIES, Ltd. Feb. 26, 1947, No. 5510. [Class 37] Components to be tested are mounted in a conveying mechanism which presents each component in turn to testing terminals, means being provided for holding the component until after the testing operation, the testing apparatus operating means for dropping the components into receptacles in accordance with the result of the test. In the construction shown a drum is divided into eight screened compartments and is rotated by a stepping mechanism so that each compartment in turn is presented to a screened chamber 5. Each resistor to be tested is dropped into a compartment and rests in a cradle 6 with its leads in close proximity to terminal blocks 7. A pivoted assembly 9 is arranged in each compartment and is shown in compartment 10. When a lever 12 engages a cam track 13 the assembly pivots about a shaft 14 and presses the resistor leads against the blocks 7. In this position the resistor is carried round .to the compartment 5 where the test is carried out. If this is satisfactory the resistor is released and falls into a hopper 17 when the lever 12 disengages from the cam track 13. If the resistor is unsatisfactory the detector operates a solenoid 18 which prevents release of the resistor until it engages a cam 19, which allows it to fall into a hopper 20 for rejected resistors. A number of solenoids 18 may be provided so that resistors may be sorted into various grades. The invention is also applicable to the measurement of the capacitance of small capacitors and the temperature coefficient of resistors.

Abstract: 886,236. Viscosimeters. SUCKER G.m.b.H. GEB. Feb. 20, 1958 [Feb. 23, 1957], No. 5558/58. Addition to 740,922 as improved upon by 768,472. Class 106 (2). Apparatus for testing a sizing liquid in accordance with the parent Specification, is modified by the use of a different form of variable restriction. The outlet from the viscosity meter 3 communicates with a tubular member 5 into which projects an axially adjustable peg member 52. The sizing liquid is pumped from a container 1 by a pump 2 and into the chamber 3 from beneath. From the chamber 3 it flows back by way of a conduit 4 and the member 5 into the container 1. Records are made both of the pressure of the gas in the chamber 3 and also of the temperature in the container 1, the pressure being a direct measure of the viscosity of the liquid. A float 34 prevents the liquid from flowing into the outlet pipe 31 of the chamber 3. The passage in the member 5 is formed between a conical peg 52 and a part-conical member 51. The peg 52 is adjustable axially by screwing, the amount of adjustment being indicated on a scale 55, and a spring-urged ball (not shown) is used to hold the peg in one of several positions. The liquid may be pumped for periods of four minutes with a run of about 10 to 20 seconds in the other direction in between. During the reversal, a negative pressure exists in the chamber 3 and this may also be indicated to give a measure of the viscosity.
