Patent GB-1433172-A (GB)
Title: Alarm systems
Inventor: LOFGREN S T J
IPC: G08B13/22
Filed: 1973-04-13
Abstract: 1433172 Detecting moisture electrically IMPULS REGULATOR I LYCKSELE AB 13 April 1973 [13 April 1972] 17918/73 Heading G1N A moisture detector and alarm system includes a moisture detecting strip 5 having conductors 6, 7 corrected by a resistance 8 and operative to provide a signal to a threshold detector in an alarm condition detecting circuit 111 which provides an actuating signal to an alarm signalling circuit I when the signal from the strip exceeds a threshold value, there being provided testing means operative periodically to lower the predetermined threshold value below the normal value of the signal from the strip 5 in a non-alarm state. The threshold detector is constituted by a trigger circuit made up of transistors Ti, T 2  which receives periodically a test pulse from the collector of T12 via resistance R6, due to capacitor C7 charging via resistance R21  until transistor T13 triggers to discharge this capacitor and provide the test pulse from T12. The capacitor then re-charges and so on. Provided current is passing through strip 5 and terminal resistance 8 (i.e. strip is unbroken), the trigger circuit produces in response to the test pulse a voltage, via transistor T3 and diode D1, to energize the multi-vibrator T6, T7. This voltage also passes to RC circuit C1, R9 and produces a pulse to enable transistor T4 which acts via transistor T6 to block transistor T8 so that the alarm bell K is held inoperative, and which acts via capacitor C3 to block transistor T7 which blocks transistor T9 so that the alarm lamp L1 is held inoperative. Strip fault indication., Should there be a break in the strip 5 or resistance 8, the trigger circuit will not be triggered so that resistance R7 will not receive current from transistor T3. Consequently thyristor T10 receives no signal at its gate and having been switched off by the test pulse via capacitor C6 cannot be reenergized. Thus current from resistance R19 passes to the base of transistor T11 and the faultindicating lamp L2 is illuminated. Alarm indication. Presence of water on strip 5 triggers the appropriate alarm condition detecting section III, there being a plurality of such sections, to cause energization, as described above, of the multi-vibrator T6, T7. (Since T4 is able to block it only for the duration of a test pulse.) Thus the bell K and lamp L1 will be activated by alternate pulses from the multi-vibrator. A push button TK allows thyristor T5 to block transistor T8 via T6 to disable the bell whereas the transistor T7 is enabled to illumi-  nate lamp L1 continuously via T9. Plural alarm indications. If another section III is triggered after button TK is pressed, a pulse is received from the respective capacitor C1 and diode D2 whereby T5 in section I is blocked so the multi-vibrator T6, T7 is re-started to give an alarm indication as before.

Patent GB-1171525-A (GB)
Title: Electric Cooker Control Means
Inventor: DIEHL KARL
IPC: H05B1/02
Filed: 1967-04-20
Abstract: 1,171,525. Control systems for electric heating apparatus. K. DIEHL. 20 April, 1967 [22 April, 1966], No. 18177/67. Heading H2H. [Also in Division H1] An energy regulator for an electric cooker includes a thermal switch comprising a bimetallic strip 2 heated by a winding 15 serially connected to a snap action contact set 14 actuated by the bimetallic strip and a contact set 20 actuated after a predetermined number of cycles of the strip via a rack-and-detent device 17, 21. The regulator is designed to bring a substance rapidly to the boil and thereafter to reduce the rate of heating. The bimetallic strip 2 and a compensating bimetal 1 are mounted on a pivoted support 4 and the average heating output is adjusted by means of a rotary cam-shaft 7, 8, 9, 10, 11 which cooperates with the compensating bimetal 1. The bimetal support 4 is movable with the rack 17 so that the bimetal 1 co-operates initially with the rapid boil cam 10 and finally with the continued cooking cam 7. The cam-shaft may be moved with rack 17 instead of the bimetal support. In operation, rack 17 is depressed for rapid boiling by a key 16 and locked in place by detent 21. Contact set 20, which is in parallel with a compensating resistance 24 (Fig. 4) is therefore closed, shorting resistance 24 so that a large current initially flows through a temperature sensitive element 25 with a positive coefficient and hot plate resistance 22 and a smaller current flows through bimetallic heating winding 15. The bimetallic strip 2 therefore begins cycling slowly, opening and closing the circuit of heating winding 15 and hot-plate heater 22 by means of contacts 14, and allowing the rack 17 to move one step to the left with each cycle. As element 25 becomes hotter its resistance increases so that more current flows through bimetallic strip winding 15 and the rate of cycling of bimetallic strip 1 increases. Eventually rack 17 is released completely opening contacts 20 so that compensating resistance 24 is connected in series with hotplate resistance 22 and the heating current through resistance 22 is reduced. In addition, the rack moves the bimetallic compensating strip 1 on to the continued cooking " cam 7 so that contacts 14 are opened for longer periods, thereby reducing the average heat output of the hotplate.

Title: Improvements in or relating to resinous compositions and varnishes made therefrom
IPC: C08G8/28
Filed: 1928-06-22
Abstract: 293,453. Bakelite Corporation, (Assignees of Turkington, V. H.). July 7, 1927, [Convention date]. Synthetic resins. - Resinous compositions are made by reacting a phenol with a fatty oil, and combining the product with a methylene-containing hardening agent, a sufficient proportion of non-phenolic resin being present to act as a blending agent. Suitable fatty oils comprise tung, linseed or rape oils or mixtures thereof, tung oil being preferred. Suitable non-phenolic resins comprise most natural resins including rosin, rosin-glycerine ester, copals and elemi, and also coumarones, phthalic-anhydride-glycerine resins, furfural and acetone resins. The proportions of a phenol and oil are such that all or nearly all the phenol combines with the oil. The amount of methylene-containing body, such as formaldehyde, paraformaldehyde, hexamethylenetetramine, should be the equivalent of 6 mols of formaldehyde to 6 mols of phenol used. The amount of non-phenolic resin should be not less than 20 parts by weight to 100 parts of phenol used, but may be increased up to 1500 parts. In an example, phenol, tung oil and a little phosphoric acid are heated, and formaldehyde, rosin and a little aqueous ammonia added. After evaporation of water heating is continued to give a product which is a clear non-tacky solid at room temperature. Phosphoric or boric acids may be used as catalysts for the phenol and oil reaction. The second reaction may be produced with or without acid, neutral or alkaline catalysts. The products may be liquid when hot and non-tacky solids when cold and may be used liquid or dissolved in solvents such as turpentine, toluene, xylene, &c. as varnishes, with or without metallic driers &c. Specification 267,736 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes the presence of acid resins, such as rosin or manila copal, during the reaction between the phenol and oil. This subject-matter does not appear in the Specification as accepted.
