Title: Improvements in carburettors for internal combustion engines
IPC: F02M19/08
Filed: 1922-11-03
Abstract: 215,247. Monier, F. Nov. 3, 1922. Addition to 188,636. Spray carburettors.-The carburettor described in the parent Specification is modified by providing an annular chamber 49 communicating with the induction pipe and with the atmosphere through a plugcock 51. The fuel nozzle 8 is supplied through a central tube 5 of the float chamber and opens into an annular chamber 16 which communicates with the induction pipe by an annular orifice 14 and holes 17. The throttle valve 19 is caused to slide on a tube 42 by a handle 22 and levers 20; it has grooves 28 for the slow-running mixture, and a conical valve 26, which is normally kept against a shoulder on the throttle-valve bv a spring, but closes the holes 17 before the throttle is quite home. This allows fuel to collect in the annular chamber 16 and to be used for acceleration when the throttle is suddenly opened. The pressure in the floatchamber is regulated by an annular passage 46 and a duct 47. Specification 213,870 also is referred to.

Abstract: 1,095,616. Subscribers' number senders. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. May 16, 1966 [May 19, 1965], No. 21555/66. Heading H4K. In a push-button number sender which comprises two sets of resistors 10 . . . 12, 14 . . . 16 in series with opposed rectifiers 13, 18, the buttons select one resistor of each set in coordinate fashion, the line current being reversed to effect sequential control, and the buttons are provided with additional contacts to present a short-circuit should the caller press two adjacent buttons simultaneously. In this event a tone may be reverted from the exchange to tell him to restart sending. The button 0 which controls only one set of resistors is exceptional, however, and it is preferably well spaced from the button 8.

Title: Improvements in machines for and process of applying tab strips to travelling webs
IPC: B65H35/00
Filed: 1947-08-07
Abstract: 631,218. Attaching tabs to webs. JOHNSON & JOHNSON (GREAT BRITAIN), Ltd. Aug. 7, 1947, No. 21664. Convention date, Aug. 9, 1946. [Class 73] A machine for applying tab strips to adhesive webs so that the leading end of the web, when wound on a spool; may be easily grasped, comprises means for feeding the web in one direction, means for feeding the tab strip in a transverse direction and severing a length of it equal to the width of the web, and bringing the tab strip into engagement with the adhesive surface of the web after a predetermined length of web has been fed. The web 10, Fig. 2, is fed from a roll by means of two contra-rotating rollers 16, 17 over which it is fed with the adhesive side contacting roll 16. The web is then fed over a guide roller 18, Fig. 4, and under a platen roller 19 where it is severed longitudinally into strips, alternate strips being wound on separate mandrels 23, 27. The mandrels 23, 27 are mounted by pin, slot and spring mechanism and are removable. The rollers 16, 17, 19 and mandrels 23, 27 are geared together to rotate from the main drive. The tab strip 74, Fig. 13,. is fed transversely to the direction of feed of the web from a roll 75 at a position in front of the roller 18. The strip is pulled from the roll 75 by means of a rotating roller 79 and passes between two coacting feed rollers 85, 86 one with a slot and the other with a groove, which produces a ridge in the tab strip and so stiffens it. The strip is fed into a groove 121 in a block 120 pivotally mounted on a table 122 shown in section in Figs. 10, 11. The block 120 is held in the horizontal position by springs 124 attached to the table 122. The block 120 is raised into the position shown in Fig. 11 to apply the strip to the web by means of a plate 129 supported by a piston in a pneumatic cylinder, operating against the action of springs 124 and 133 ; and the tab strip is secured in position by passing over roller 18. A cam shaft 140, Fig. 2, co-operating with a ratchet and pawl mechanism and driven from the main drive, feeds the tab strip in predetermined lengths in timed relation to the web feed, and also operates a valve to admit air to the piston which raises the block 120. A similar piston operated in a similar manner actuates a severing device 98, 99, Fig. 13, for the tab strip after its feed has been arrested. The lengths of tab strip fed may be adjusted by changing the relevant cam on the shaft 140. The web strips may be severed by the operator after the tabs reach the mandrels 23, 27 and new mandrels then put into position.

Title: Gaseous chromatography
IPC: G01N30/56
Filed: 1963-05-31
Abstract: A gas chromatography column is prepared by fluidizing a filled column and thereafter reducing the gas speed to give a fixed bed.  The fluidizing gas and the carrier gas may be the same whilst the fluidizing gas may be heated to the temperature required for the chromatography operation and the column may be fluidized in the thermostat of the chromatography apparatus.  The filling may be stabilized by using a material which may be lightly sintered, alternatively by including a mineral which is fusible at low temperatures or an organic product which leaves, after roasting, a few traces capable of increasing the coherence of the filling grains. In an example, a stainless steel column 1 m long, 6 cm int. dia,. was filled with sieved roasted diatomaceous earth mixed with a melamine formaldehyde resin having a silicone oil thereon.  The filling was fluidized using nitrogen containing ammonia at 40 DEG C., and then allowed to become fixed once again. The separation of a mixture of pentane and hexane is described.

Title: Improvements in or relating to the hardening of moulds and cores
IPC: B22C9/12
Filed: 1958-07-14
Abstract: 857,109. Making moulds and mould cores. WALTER & CIE A.G. July 14, 1958 [July 16, 1957], No. 22459/58. Class 87(2). [Also in Group XXIX] Moulds and cores containing a medium such as water glass hardenable by CO 2  are hardened by applying CO 2  which has been first discharged in liquid form from pressure cylinders or storage containers and then passed through a vaporiser, the final temperature of the gaseous CO 2  being such as to produce rapid optimum hardening. The liquid CO 2  is stored in steel cylinders a, b, or a low pressure heat insulated container f maintained at a low temperature, and passes along a conduit c to a pipe coil inside vaporiser d, the temperature of which is maintained by an adjustable heating element e. From there the CO 2  gas passes through a reducing valve h and then at about 2 atmos. pressure into a discharge valve i. In the the case of water glass being used as binding medium, the temperature of the heat transferring liquid in the vaporiser d may, for example, be at about 85‹C. and the final temperature of the CO 2  will be about 35‹C. With high consumption of CO 2  and inadequately dimensioned heat transfer surfaces, the temperature of the gas may fall below the desired value and to avoid this a second pipe coil may be provided in the vaporiser which heats the cooled gas discharging through the reducing valve again to the desired temperature. So that the heat transfer liquid need be heated only slightly above the desired temperature, e.g. 35‹C., a small buffer vessel is arranged in the vaporiser and is constantly filled with a store of preheated CO 2  gas. The discharge valve is adjustable so as to control the amount of gas supplied to the mould or core.

Title: Improvements in or relating to the treatment of citrus fruit
IPC: A23L2/06
Filed: 1961-06-22
Abstract: To preserve fresh flavour in citrus fruits, especially oranges, and their juices, the peeled fruit is immersed in a cold liquid for a period sufficient to solidify the fruit and separate, by thermal shock, the juice cells from other parts of the peeled fruit.  The peeled fruit, preferably subdivided into its segments, is dipped into, or sprayed with, liquid nitrous oxide at -128  DEG F., liquid nitrogen or liquid air, 9 sec. treatment with such nitrous oxide being sufficient, and agitation of the frozen sections then causes them to crumble into individual juice cells or aggregations of juice cells and pithy material, carpellary membrances and vascular bundles which may be sieved off.  The juice cells separated may be stored in frozen condition. Separated juice cells may be thawed out and ruptured.  The shock effect of the immersion may be reduced by preliminarily coating the peeled fruit or fruit segments with sugar solution.
