Title: Instrument for the accurate measurement on stationary means of the angle of twist of a system executing a continuous rotary movement
IPC: G01N11/14
Filed: 1954-10-01
Abstract: 768,161. Indicating-apparatus; viscosimeters. INSTITUT DE RECHERCHES DE LA SIDERURGIE. Oct. 1, 1954 [Oct. 16, 1953], No. 28303/54. Classes 106 (2) and 106 (4). An arrangement for measuring the angle of twist in a driven rotatable system is particularly applicable to a viscosimeter, in which a motor 1 drives a cylinder 6 within a cup 7 through a thread 3, for finding the difference in the angle of twist of the thread 3 with and without a sample in the cup 7. The thread 3 carries a switch part 8 and a mirror 5 for throwing an image of an illuminated slot 13 on to a ground glass screen 14. Before a sample is placed in the cup 7, an annular scale 2 and vernier scale 16, both preferably mounted on ball-bearings, are looked together with their zero marks in coincidence and turned until the image on the screen 14 coincides with a mark 15, the image being formed when a lamp 11, of electronic flash type, is illuminated every time the switch part 8 contacts another part 9 carried by the scale 2 to complete a circuit through a brush 10 to an electronic generator 12, the duration of the flash being independent of the duration of closing of the switch. The vernier scale 16 is then freed from the scale 2 and locked to the frame of the apparatus, the sample is introduced into the cup 7 and the change in the angle of twist of the thread 3 causes the image to deviate. The scale 2 is then adjusted through a rack and drive means until the flashing lamp 11 produces an image co-inciding once more with the mark 14. The amount of adjustment of the scale 2 read against the vernier scale is a measure of the angle of twist.

Title: New phenyl diazonium salts and their use in diazotype materials
IPC: G03C1/54
Filed: 1964-07-15
Abstract: The invention comprises diazonium compounds of the general Formula (I) <FORM:1064128/C2/1> in which X is an anion, R1 is alkyl, cycloalkyl, or aralkyl; R2 is hydrogen or an alkyl, cycloalkyl, aralkyl or aryl radical or an alkoxy cycloalkoxy, aralkoxyl or aryloxy linked to the CO group by an oxygen atom, or a substituted amino or amido carbonyl group; R3 represents a substituted or unsubstituted saturated or unsaturated hydrocarbon radical; and R4 represents an alkyl, cycloalkyl, aralkyl or aryl radical. Compounds of the above formula in which the p-substituent is an etherified mercapto group or an acylthio group are prepared from a 5-chloro-2-substituted oxy-1-nitrobenzene by reducing to the corresponding substituted aniline; acylating the amino group; nitrating and deacylating the product to give the 5-chloro-4-nitro-aniline derivative; replacing the chlorine radical by a mono-substituted amino group and replacing the free amino group by a chlorine atom (by diazotization and the Sandmeyer diazo reaction).  To obtain an etherified mercapto group in the p-position the 5 - substituted - 4 - chloro - 2 - substituted amino-1-nitrobenzene so obtained is treated with a mercaptan which is acylated, e.g. by treatment with a carboxylic acid chloride, or carboxylated with an ester of chloroformic acid and reduced; the required diazonium compound is produced from the product by standard methods.  To obtain the diazonium compounds having acyl or carboxy thio derivatives in the p-position a 5-substituted-4-chloro-2-substituted amino-1-nitrobenzene is reacted with Na2S2 and a carboxylic acid chloride or a chloroformic ester. The nitro group of the 4-acyl thio compound thus produced is reduced to an amino group and the resulting compound is diazotized. Compounds having a cyanothio group in the p-position are prepared similarly except that the cyanothio group is introduced by reacting the 2-N-substituted-5-substituted-oxy -1-nitrobenzene with Br2 and KCNS, the product so obtained being reduced and diazotized. Numerous examples are given of the products and their preparation in which for example R1 is methyl, ethyl, normal butyl, cyclohexyl or hydroxyethyl; R2 is butyryl, methyl, ethyl, benzyloxy, ethoxy, methoxy, butoxy, phenoxy, diethyl- and dimethylaminoethoxy and chlorethoxy; R3 is ethyl, benzyl, p-toluyl, carboxymethyl, KSO4CH2-hydroxyethyl 2,4,4 - trimethylpentyl-, allyl, phenyl, cyano, C2H5COO-, propenyl and naphthyl; and R4 is methyl, butyl, cyclopentyl, p-chlorophenyl- and benzyl.  In addition examples are given in which two of the diazophenyl are nuclei and are connected at the 2 or 4 positions by an alkylene bridging group.

Title: Improvements in electric emergency switches
IPC: H01H3/02
Filed: 1956-09-24
Abstract: 820,453. Retractive switches; switches held set and freed mechanically; switch cases. ASSOCIATED FIRE ALARMS Ltd., and JACKSON, J. Sept. 24, 1957 [Sept. 24, 1956], No. 29182/56. Class 38 (5). An emergency switch of the kind wherein fracture of a glass or like fragile cover either operates the switch automatically or enables the switch to be hand-operated, comprises a easing 10 having a hinged lid 11 with a circular glass window 13. A block 15 of insulating material carries a metal block 16 in which a plunger 18 is slidable against a spring 30. The plunger 18 is normally held in its mid-position by glass 13 and a transverse member 20 engages spring blade 24 to hold contacts 28, 29 open. When the glass 13 is broken the plunger 18 moves outwardly to allow contacts 28, 29 to close. If the plunger 18 is fully depressed the member 20 passes beyond the spring blade 24 and contacts 28, 29 are again closed. A U-shaped lever pivoted at 33 on block 16 carries on one arm 30a a subsidiary plunger 32 urged into engagement with the lid 11 by a spring 35 acting on the other arm 30b. When the lid 11 is opened the arm 30b engages blade 24 and prevents contacts 28, 29 from closing. The contacts may be closed with the lid open (e.g. for test purposes) by depression of the plunger 32. A second set of contacts may be operated by the opposite end of member 20 as indicated by dotted lines in Fig. 3. In Fig. 6 the member 20 is arranged to engage blade 24 on depression of plunger 18 and thereby close contacts 128, 129. A lever 40 pivoted at 41 and under action of a spring 45 engages a groove in plunger 18 to maintain it depressed. The plunger 18 in this embodiment does not engage the glass 13 and must be depressed after fracture of the glass, only being released by opening the lid 11 and operating a handle portion 46 of the lever 40. This latching feature may also be provided on the first embodiment of the switch.

Title: Temperature control circuit
IPC: G05D23/24
Filed: 1960-08-24
Abstract: 912,308. Thermal switches. STEVENS MANUFACTURING CO. Inc. Aug. 24, 1960 [Sept. 18, 1959], No. 29249/60. Class 38 (5). [Also in Group XXXV] A system for controlling the temperature of a vessel having a heating unit 12 comprises a sensing coil 21 associated with contacts 30, 31, in series with the heater. When a control shaft is moved from an " off " position, power contacts 44, 45, for the heater are closed by cam 47, a cam 28 varying the position of follower 32 and hence that of bimetallic structure 25. The shaft has three operative positions for varying the pressure between contacts 30, 31, to control the desired temperature setting. The resistance of coil 21 increases with rising temperature so that more current from transformer 55 is diverted to control winding 64 to heat bimetal 38 the upward flexing of which separates contacts 30, 31. A voltage compensating winding 66 associated with bimetal 26 causes cyclic operation of contacts 78, 79, in circuit with control winding 64 and coil 21. Thus, the average temperature of the vessel is primarily regulated in accordance with the on-off periods of the contacts 30, 31. A bimetal 37 in series with the heater also operates the contacts 30, 31, to increase the rate of cycling as compared with the operation obtained with bimetal 38 alone. A bimetal 35 provides compensation for changes in ambient temperature for the bimetal 25, the bimetal 26 also being ambient temperature-compensated. An increase of supply voltage increases the voltage across control winding 64, but a proportionate change is also applied to winding 66 whereby the average current supplied to the control winding is decreased. The contacts 30, 31 are thus substantially unaffected by voltage changes. The connection of winding 66 in series with the parallel-connected windings 21, 64, also affords greater sensitivity in the operation of contacts 30, 31. A flexible pigtail 49 imparts heat to the bimetal 37 in proportion to the heating effect of the unit 12. The bimetal 37 permits various rates of boiling with various wattage inputs to the unit 12 without appreciable change in temperature of the vessel, the cam 28 changing the stress on the bimetals to vary the on-off periods of the contacts 30, 31. Snap-action of these contacts is afforded by permanent magnet 70 and armature 71. A pilot lamp 76 is provided. Specification 871,976 is referred to.

In a gas-fuelled smokers' lighter a burner 5 is located under a cover 13 which forms part of a pressure key 1 for operating an ignition mechanism 20, 21, and the cover is formed with a flame outlet orifice 14 which in use enables a flame to flash outwardly therethrough but which is sufficiently small to prevent flashback of the flame to the burner itself. As shown, the pressure key extends substantially entirely over the top of the lighter housing 2, and the key has a peripheral skirt 15, the key and skirt together providing a structure which is imperforate apart from the orifice 14. The key is spring-loaded in a guide tube 10, and on depression of the key pins 16 riveted to the skirt 15 engage curved tracks 22 of a driving member 21 which thus pivots about two mountings 19. Flint wheel 20 is accordingly rotated by the action of a drive spring, and an actuating lever 7 is released to pivot about pivot point 18, thereby opening a spring-loaded valve 6.
