Abstract: 1,233,675. Roadway de-icing. B. F. HINRICHS. 25 July, 1969 [7 Aug., 1968], No. 37451/69. Heading E1G. Ice is prevented from forming on a roadway 10 by means of apparatus which automatically sprays liquid or granular de-icing material (e.g. salt) on the roadway when actuated by a control circuit which includes a thermostat and optional humidistat. As shown, roadside salt hoppers 14 each have a discharge opening 26 and a spraying motor 18; alternatively the de-icing material may be a liquid stored in a tank and supplied by gravity via a solenoidcontrolled valve or by a pump to a perforated conduit lying alongside the roadway. The control circuit includes a timer 30, a thermostat 38 and humidistat 40. The timer 30, which includes a motor 32 whose shaft drives, switchactuating cams 46 and 52, controls the time periods of spreading; cam 46 closes switch 42 in the motor circuit to ensure rotation of the motor 32 through a complete cycle, and the spaced lobes on cam 52 close switch 28 periodically to energize the spreading motor 18. The thermostat 38 is preferably buried just below the surface of the roadway, with an additional thermostat or a humidistat 40 just above the surface.

A coating device for thin layer chromatography plates comprises side parts 1, 1a and connecting parts 4, 5 which are non-adjustably mounted at an angle to leave a slit for the egress of coating material the lower edges 2a of the side parts 1, 2 having guides 3 which engage over the edge of the plate to be coated, the difference in height between the edges 2a of the side plates and the lower edges of the connecting plates thus determining the thickness of coating to be applied. The lower edges of the connecting plates are formed as doctor blades and are of transparent synthetic plastics resin which can be ground away to achieve the required coating thickness. In a modification, not shown, a second vertical connecting part such as 4 can be placed adjacent the angled plate 5 and with the provision of guides on the upper surfaces of the side parts the coating device can be used either way up when it is preferable to provide different coating thickness with each pair of connecting parts.

Abstract: 1,250,651. Printed circuit assemblies. WESTERN ELECTRIC CO. Inc. 30 Oct., 1968 [31 Jan., 1968], No. 51394/68. Heading H1R. A plurality of separate contact areas on a header are formed by first forming a conducting pattern of the shape of the required contact areas on the header including portions interconnecting the areas, then plating metal on to the pattern and finally heating the interconnecting portions by passing a current therethrough so as to melt them and thus isolate the contact areas. Ceramic substrate 12 is screen printed with moly-manganese metal 17 and sintered to form a pattern including contact areas 16 surrounding apertures 15 connected by runners 22 to a peripheral ring 21 made up of arcuate portions 23, 24 of dissimilar cross-section. The substrate 12 is then placed in a barrel plating apparatus and the pattern plated uniformly with a layer 18 of nickel, Fig. 4. Terminal pins 11 provided with an annular brazing preform over portion 13 are inserted into holes 15 until the pin heads 14 abut the preform which in turn abuts plated layer 18. The heads 18 are then brazed to the areas 16 simultaneously with the brazing of a metal coating on the base of the substrate 12 to platform 25. After testing a gold layer 19 is plated on the header. In order to disconnect the terminal areas 16, a current from source 26 is applied between adjacent pairs of pins in succession so that intermediate portions 24 are burned away. Integrated circuit chips are then mounted on the header. In the header of Figs. 5 and 6 (not shown), a plurality of discrete contact areas are isolated from a peripheral grounding ring, necked down portions in this case being provided between the grounding ring and contact areas along the radial runners. The top portion of this assembly after the nickel plating operation is coated evaporatively with titanium and gold and then etched so as to leave the titanium and gold only over the contact areas.

Abstract: 1,252,129. Controlling fuel injection photoelectrically. SOC DES PROCEDES MODERNES D'INJECTION SOPROMI. Nov. 11, 1968 [Nov. 27, 1967], No.53388/ 68. Heading G1A. [Also in Division F1] The duration of fuel injection to an internal combustion engine is controlled by rectangular pulses produced by a frequency discriminator receiving pulses from a pulse generator dependent upon engine speed and throttle setting. The pulse generator comprises a transparent cylinder 1 with opaque lines 3 thereon driven by a shaft 4 from the engine. A light or infrared source 18 and a detector 19 are linked to the accelerator to co-operate with different axial points on cylinder 1 for different accelerator settings. The frequency discriminator provides an output so long as the frequency of the pulses from detector 19 is above a threshold level so, to provide constant injection periods independently of speed, the spacing of lines 3 would have to increase hyperbolicly, but in practice empirical deviations are made from this law to achieve optimum operation. A graphical method of constructing the lines 3 using desired injection duration/speed curves is described.

Abstract: 1,266,933. Controlling clock pulses. OMRON TATEISI ELECTRONICS CO. 22 May, 1969 [3 June, 1968], No. 26109/69. Heading G4A. In an apparatus for controlling clock pulses in a device, the operation of which device progresses in accordance with clock pulses and operative cycles of pulses derived from the clock pulses, generation of the clock pulses is stopped between cycles. Clock pulses are generated by oscillator 1 and feed timing unit 2 which distributes operative cycles of pulses. At the end of each cycle a signal SE triggers a transistor monostable circuit 3 to stop generation of clock pulses in oscillator 1 for a variable time until the next cycle is due to commence.

Abstract: 1296335 Sheet roll dispensers CWS INTERNATIONAL AG 15 July 1971 [26 Aug 1970] 33174/71 Heading A4G Paper towels may be dispensed from roll 11, Fig.2 or when nearly expended, paper may be dispensed from the old roll at 18 together with paper from a new roll 11 over metering roller 13 which makes between a time delay stop one rotation for the double layer from both rolls and two rotations for a single layer from only roll 11. When roll 11 is near exhaustion, spring flap 47 raises refill sign 48 hinged on pivoted frame 15 carrying sprung nip-roller 14. During a first rotation of roller 13 for a single layer, spring- loaded trip 19, Fig. 4 on the roller rotates and lifts weight loaded pawl 27 on to pin 31 and lifts arm 25 partly towards a position in which timing cups 23, 32 meet. A second rotation allows trip 19 to press the cups together by acting on arm abutment 29 after which the roller 13 is stopped by the trip meeting arm abutment 33. When the timing caps part, arm 25 swings below its portion in Fig. 4 with the left arm of pawl 27 off pin 31. If two rolls are being dispensed, flap 36, 37 rests on roll 18 and turns tappet 35 to shift pawl 34 into a notch preventing arm 25 moving below its position in Fig. 4, whereby roller 13 and trip 19 only make one revolution to press the timing cups together. In place of flap 37, a spring slide may be displaced by the end of roll 18 to press a spring on to the left arm of pawl 27 so that it is not disengaged from pin 36 and arm 25 never drops below the position in Fig. 4. When the timing cups release the arm end abutment 33, trip 19 and roller 13 under spring action rotate and forward a portion of paper for grasping.

In the construction shown the recess is provided in a body 1; the recess being threaded and the actuating element is attached to an actuating member in the form of a disc 14, the periphery of which is threaded so that rotation of the actuating element by the key moves the disc axially of the recess. The bolt member is slidably mounted in the recess with one end face in engagement with the disc and the opposite end portion passing through a hole in a flange of the body, the hole and the cross sectional shape of the bolt member being such that rotation of the bolt member is prevented. Thus rotation of the actuating element rotates the disc which in turn moves the bolt member axially so that its end portion protrudes further from the hole in the flange. In the case of a sash window the lock is fitted to the uppermost sash and when the bolt member is in a protruding position it prevents openings of the sash more than a limited extent by coming into engagement with a plate secured to the lower sash. In the case of a casement window the bolt member when in the protruding position protrudes through a hole in a keeper secured to the casement the lock being secured to the frame.
