Abstract: 387,274. Boot-cleaning devices. STEINMETZ, S., 3, Iranyi Daniel Utca, Kispest, Hungary. Sept. 9, 1932, No. 25164. [Class 138 (i).] A door-mat comprises a corrugated base part 2 having flat troughs and preferably having beads or projections 12 on the crests, and a part 1 comprising side beams 3 connected by brush bars or cylindrical brushes 5<1>, 6<1>, 7<1> as cross members. The part carrying the brushes is placed over the base part, and the troughs of the corrugations serve to house the brushes and to collect the dirt while the projections 12 act as scrapers. The two parts of the mat may be articulated so that they may be folded for shipping.

Title: Welding of metal elements to metal members

Filed: 1957-08-09
Abstract: 857,197. Making finned tubes, aircraft wings; welding by pressure. MAGNETIC HEATING CORPORATION. Aug. 9, 1957, No. 25282/57. Addition to 748,528. Classes 83 (2) and 83 (4). In welding an area of an element 11 to a band 13 of the surface area of a metal member 10, the element and member are advanced so that the area and band follow paths which approach and become contiguous at a welding point 14 where the area and band are pressed together whilst heating the area and band to their respective welding temperatures by the application to the area and band of highfrequency current by electrodes 20, 21 which engage the element and member on or near the area and band respectively at points shortly in advance of the weld point, the current being at a frequency not less than 100 kc. per sec. and such that the lowest impedance path between the electrodes follows the area and band to the weld point whereby the greater part of the current and resistance heating is concentrated in the approaching area and band and weld point. The element may be an angle iron, rib, bar, rod or ribbon and the member may be flat or curved. The element may be a strip welded to a tube to form an annular, helical or longitudinal rib or fin. In an embodiment an angle strip 11 and a plate 10 are moved in the direction of the arrows, the flange 17 of the angle strip being engaged by rollers 16 to bend the strip and hold it out of contact with the plate until its edge 12 is pressed into contact with a band 13 on the plate at the weld point by a spring-urged roller 18. The electrodes 20, 21 in fluid-cooled holders 24, 25 supply current at a frequency of 100-500 kc. per sec. or more. A small steady arc occurs adjacent the weld point. The electrodes may engage the edge and band at different distances from the point 14 so that, e.g. the edge and band may be heated to different temperatures, particularly if the element or member are of different materials. A strip may be bent transversely and slightly twisted to space its edge from a plate or tubular member in advance of the weld point. In an embodiment, rollers on vertical axes engage the strip adjacent the weld point where it is urged into contact with a plate by a spring-pressed roller and rollers on inclined axes engage the strip before the weld point. The welding of ribs or strips to aeroplane wings may be effected.

Abstract: 1,212,016. Electric selective signalling. MARCONI SOUNDING DEVICE CO. Ltd. March 4, 1968 [1 June, 1967], No. 25391/67. Heading.G4H. [Also in Division H4] A multi-range echo sounder has means for changing the range automatically in dependence on the count of digital pulses representing the measured depth. If the count lies above a preset maximum or below a preset minimum, as determined in a comparator, the range is increased, or decreased respectively, provided that the present range is not the maximum or minimum. The signal from the comparator passes via a normally open gate which is then inhibited for sufficiently long that a fresh count can be made on the new range. The preset maximum and minimum counts overlap to prevent hunting between ranges.

Title: Smoke detector
IPC: G01J1/04
Filed: 1973-05-30
Abstract: 1419146 Smoke detectors COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION AND AUSTRALIA THE COMMONWEALTH OF 30 May 1973 [6 June 1972] 25660/73 Heading G1A A smoke detector comprises two chambers having respective light detectors and a common light source; air from an area to be monitored, e.g. inside a building, is supplied to one chamber and air from outside the area, e.g. from the atmosphere, is supplied to the other chamber. Thus the effects of atmospheric pollution on the detector inside the area can be minimized by subtracting the two detector outputs. Fig. 1 shows parallel chambers 1,1' each having a photo-multiplier detector 10,10'. A xenon flash tube 15 acts as the common light source, and has diffusers 17, 17' associated with it. Apertured baffles 2-9 and 2'-9' define the field of view of the detectors, and allow the air supplied to inlets 12, 12, to pass through the chambers to outlets 13, 13'. The baffle plate construction is described, Fig. 2 (not shown), as is an embodiment in which the parallel chambers are spaced apart and have side tubes leading to the common source, Fig. 3 (not shown). The two chambers may be supplied with air from the outlet and inlet and an air conditioning unit to monitor the air conditioned area by comparing the air leaving it with the air entering it. The output from each photo-multiplier is passed to an integrate and hold circuit, Figs. 5 and 6 (not shown), having two capacitors, one of which receives the output all the time and the other only during the period when the flash tube is not activated. By subtracting the stored signals on these capacitors noise in the output can be removed, to leave only the output due to the light scattered from the flash tube to the photo-multiplier by smoke. This latter output is recorded for both chambers, and the difference of output of the two detectors may be recorded. When the difference exceeds a given level an alarm or fire extinguisher is activated, the record of the two detectors allowing an operator to see whether the alarm is due to a fire or is just a temporary effect such as cigarette smoke. Also the fact that atmospheric pollution takes time to penetrate a building and then remains in the building when the outside air is clear can be allowed for if a record is made.
