Abstract: 648,227. Inspection lamps. NEALE & SONS, Ltd., J., and NEALE, M. R. Dec. 23, 1948, No. 33208. [Classes 75(iii) and 75(iv)] An electric inspection lamp resembling a pistol has a lamp holder 11 fixed in the barrel part and the trigger or trigger guard 3 forms the movable jaw of a biassed clip for detachably securing the lamp to a support. The trigger 3 slides on a fixed rod 5 extending between the stock and the barrel and is urged by a coiled spring 4 toward a serrated part of the lamp body forming the fixed jaw of the clip. The trigger is also serrated and its upper surface is curved to engage with the correspondingly curved under-surface of the breech. The serrated jaws when closed conjointly form an elliptical slot. The trigger may be pivotally mounted. The guard portion 12 is formed integral with the breech and stock.

Abstract: 683,819. Thermal switches. ASHE, T. S., and SUNVIC CONTROLS, Ltd. Dec. 15, 1950 [Dec. 29, 1949], No. 33264/49. Class 38 (v) An energy regulator of the character described in Specification 517,538 comprises an insulating base 1 carrying a snap-action switch 20, 25, 26, which may be of the trifurcated blade-spring kind such as described in Specification 585,972, two bimetal strips 7, 8 secured at adjacent ends to a pivotally-mounted bloc 6, an adjusting cam-follower lever 10 pivoted on an axis parallel with the pivotal axis of the bimetal strips and a bridge member supporting a rotary cam 9 and a shaft 15 with an adjusting knob 41. In Figs. 1 and 3, the axes referred to are perpendicular to the base and the bridge member comprises pillars 4, 5 on which the block 6 and lever 10 are pivoted and a metal strip 17 supported by the pillars. The cam 9 cooperates with a pin 14 on the lever 10 which has a tail portion 13 with an adjusting screw 18 engaging the free end of the bimetal strip 7. The strip 8 has an abutment 19 engaging the spring 20 of the switch. The strip 7 is heated by current flowing through it or by an encircling heater coil, whilst the strip 8 responds to the temperature of the surrounding air to compensate for variations in ambient temperature, the regulator controlling the energisation of a heating apparatus e.g. a hotplate, as described in Specification 517,538. The cam 9 has a slot 44 which the pin 14 enters to positively move the screw 18 away from the bimetal strip 7 when the adjusting knob 41 is turned to the "full-on" position. When the knob is turned to the "off" position the cam 9 maintains the switch contacts 25, 26 open. If "double-pole switching" is desired, one or more additional switches 32 ... 34 are provided, a further cam 36 opening the contacts 32, 33 when the knob is turned to the "off" position. In all the operative positions of the knob, the contacts 32, 33 are closed, the control being effected by the periodic opening and closing of the contacts 25, 26. In an alternative arrangement the pivotal axes of the strip 7, 8 and the lever 10 are arranged parallel with the base 1, the arrangement being shown in Fig. 6. In this case, a one-piece bridging member 52 carries the pivot spindles 50, 56, for the block 6 and lever 10 and the cam 9 is of the face-cam type.

Title: Dehydrogenation of certain olefines
IPC: C07C5/32
Filed: 1953-12-01
Abstract: In the dehydrogenation of an olefine having at least 4 carbon atoms in the unsaturated chain, using a calcium nickel phosphate catalyst and continuously alternating operations of effecting dehydrogenation at the desired main reaction temperature, part of the dehydrogenation is effected at a temperature at least 15 DEG  F. below the said main reaction temperature and subsequently dehydrogenation is effected at the desired main reaction temperature.  Preferably a new catalyst is used and the bed temperature adjusted to 1005 DEG  F. and a mixed feed of 1 volume of n-butylene and 20 volumes steam introduced at the same temperature, at the end of 1 hour the bed is regenerated with steam at 1005 DEG  F.  During the next 24 hours the feed temperature is slowly raised to 1045 DEG  F. and in the next six days to 1125 DEG F. Specifications 623,580, [Group XXV], 634,391 and 634,580 are referred to.

Title: Improvements relating to air and water heating apparatus
Inventor: DAVIDSON WILLIAM
IPC: F24H1/20
Filed: 1947-12-18
Abstract: 649,340. Air and water heating stoves. RADIATION, Ltd. Dec. 18, 1947, No. 33399. [Class 64(i)] Water, and air for space heating, are heated, for use in buildings, in a heat insulating cabinet a containing a solid fuel stove b with a heat transmitter c, e.g. a serpentine flue, for the combustion products which flow therethrough in a zig-zag manner to an outlet i. Futhermore, air flows through the cabinet around the stove and heat transmitter, e.g. driven by a fan j, and a water tank n is arranged alongside and separate from the stove and transmitter to be heated by the radiation therefrom and by the hot air. Some of the cold air from the fan is directed along a passage o to a distributing duct k where the relative proportions of air flowing over the heat transmitter and along the passage are controlled by a damper m. A thermostat controls the supply of combustion air which passes downwardly through the fuel on the fire bars d to consume smoke. Specification 622,011 is referred to.

Title: Camera
IPC: G03B7/16
Filed: 1975-08-11
Abstract: 1484805 Camera and flash unit KONISHIROKU PHOTO INDUSTRY CO Ltd 11 Aug 1975 [13 Aug 1974] 33453/75 Heading G2A A camera has a built-in electronic flash device which can be moved from a first position to a second position in which it is more distant from the optical axis. If the more distant position is the operative position, this tends to reduce the "red eye" phenomenon. As shown, the electronic flash 3 is housed in a box 2 which can slide from a position in which it is retracted completely within the camera Fig. 3 (not shown) to the position of Fig. 4, in which it extends outside the camera in an operative position. It is released for this movement by disengaging a latch 10, 11 from the box 2, which is then pulled by a spring 6 into the Fig. 4 position. During this movement it pivots a lever 16 anti-clockwise, which allows a pair of switch contacts 19, 20 to close and so complete the flash circuit. Thus the life of the battery is prolonged since it is in circuit only when the flash is in the operative position. Lever 16 itself engages with a flash changeover ring 21, and pivots it clockwise when moving to the Fig. 4 position. This moves a cam part 21b clear of a pin 24 on a diaphragm driving plate 23. Plate 23 can now be moved by a spring 33, to engage in an automatic arrangement for setting the aperture to correspond with the photographing distance. The position of plate 23 can also be adjusted by engagement of the shaft 28 on which it pivots by a cam 22b of a guide number ring 22, which can be adjusted from outside the camera to compensate for differences in film sensitivity.

Preferably the tubes are disposed vertically with two or more of the tubes being combined to form a smaller number of tubes either continuously or in stages in the direction of the reactant flow.ALSO:<FORM:0780971/IV (a)/1> A reactor for the catalytic hydrogenation of carbon monoxide in the presence of a liquid medium is cooled by a series of tubes disposed within the reactor through which tubes a cooling medium may be passed, the tubes being decreased in number in the upward direction whereby the total outer surface area of the tubes decreases in the same direction either continually or in stages. Preferably the tubes are disposed vertically with two or more of the tubes being combined to form a smaller number of tubes either continously or in stages in the direction of the reactant flow. In a vertical reactor of height 12 mm., the 360 water-cool tubes are reduced at a position approximately 3 m. after the entry of incoming gas to 270 and at further intervals of 3 m. to 180 and finally 90.  In the hydrogenation of carbon monoxide, using an ion catalyst, local overheating is avoided; and a higher production of hydrocarbons and lower product of methane is obtained and the life of the catalyst is also lengthened.
