Title: Timing system for ice making apparatus
IPC: H02P7/20
Filed: 1947-06-09
Abstract: 629,969. Ice-making. WILLIAMS, J. D. June 9, 1947, No. 15173. Convention date, July 16,1943. [Class 29] In an apparatus for making tube-ice as. described in Specification 632,439 for example, the solenoid operated valves 21, 23 connecting the evaporator 2 to the compressor suction and to the hot gas supply from the condenser respectively, the valve 28 controlling the supply of thawing water to the chamber 9 around the ends of the freezing tubes, the motor 13 driving the ice cutter 11 and the motor 18 driving the freezing water circulating pump are energized in correct sequence through mercury switches 35 rocking on rotating coaxial cams 31-34 driven one revolution during the ice-freeing period by a constant speed motor 40 and at rest during the freezing period, the motor 40 having a holding circuit operated by a cam 42 and being intermittently operated by a controller 43. The controller 43 comprises a synchronous motor 44 driving through a solenoid operated clutch a pointer 46 co-operating with a scale 48 calibrated in minutes and having an index 49. A normally open switch 52 is closed by the pointer 46 in the zero position and a normally closed switch 50 carried on the index 49 is opened by the pointer 46 when it reaches the index 49. A solenoid 47 operates the clutch and a switch 51 in its holding circuit. The pointer 46 is urged by a spring 58 towards the zero position. The pointer 46 carries a spur 55 with a short lug 56 and a long lug 57 which operate a mercury switch 53 in the supply circuit of the motor 40. Manual switches 45, 59, 60 are provided. The setting of the index 49 determines the duration of a whole cycle. When a freezing period is nearing its end, the switch 52 is open, the switch 50 closed and the solenoid energized. The cams are stationary and the pointer 46 is nearing the index 49. When the pointer 46 reaches the index 49 the switch 50 is opened de-energizing the solenoid 47 and so disengaging the clutch and releasing the switch 51. Under the influence of spring 58 the pointer returns towards the zero position, the lug 56 passing the switch 53 which is engaged by the lug 57 and thus closed whereupon the motor 40 starts and initiates the ice-freeing period. When the pointer 46 reaches zero it closes switch 52 and the solenoid 47 is energized to close its holding switch 51 and engage the clutch. The pointer now traverses to the right, Fig. 1, the lug 56 picking up the switch 53 which is thus broken, the motor 40 being now energized through its own holding circuit cam 42. The end of the ice-freeing period is determined by the breaking of this holding circuit after one rotation of the cam whereupon the freezing period begins and continues until the pointer reaches once more the index 49. The switch 59 is provided so that on initial starting up, the motor 40 will not operate to produce an ice-freeing phase.

Title: Improvements in and relating to the manufacture of fatty alcohols
IPC: C01F7/36
Filed: 1963-04-17
Abstract: Aluminium hydroxide is produced by hydrolysis of aluminium alcoholates whereby the alcoholate is preheated to not less than 80 DEG  C. and poured, within a period not exceeding 30 seconds, into water at not less than 98 DEG  C. and is caused to be hydrolysed under self-sustaining reaction conditions at not less than 98 DEG  C. without stirring or the application of external heat for the lesser of the period required for substantially complete reaction and a period not exceeding 20 minutes. The product is then cooled to 60 DEG to 70 DEG  C. to form two layers. The aluminium hydroxide is obtained by filtering the bottom layer, which is then leached with an alcohol-soluble low-boiling organic solvent.  The aluminium hydroxide is then dried, e.g. at 105 DEG  C.  The reaction is preferably carried out under neutral conditions and with ebullition of the aqueous phase under reflux, and the ratio of aluminium alcoholate to water is within the range 1 : 20 to 1 : 50 based on the weight of aluminium in the alcoholate.  The alcohol component of the alcoholate preferably has less than 26 carbon atoms. The alcohol-soluble low-boiling organic solvent may be a hydrocarbon of boiling point 30 DEG  to 50 DEG  C., a primary aliphatic alcohol, or an aliphatic ketone, both with up to 6 carbon atoms.ALSO:Alcohols are produced by hydrolysis of aluminium alcoholates whereby the alcoholate is preheated to not less than 80 DEG C. and poured, within a period not more than 30 seconds, into water at not less than 98 DEG C. and caused to be hydrolysed under self-sustaining reaction conditions at not less than 98 DEG C. without stirring or the external application of heat for the lesser of the period required for substantially complete reaction and a period not exceeding 20 mins.

Title: Method and apparatus for measuring neutron characteristics of a material

Abstract: 1,163,515. Neutron well logging. SOC. DE PROSPECTION ELECTRIQUE SCHLUMBERGER. March 29, 1968, No.15198/68. Heading G1A. [Also in Division G6] To investigate the nature of earth formations in a well bore the formations are irradiated by the pulsed neutron source, 30, and are subsequently scanned by the radiation detector 35 which responds to the thermal neutron concentration in the formation, 34. The instrument 30, is lowered in the bore 31, by the cable 32, the neutron source 33, is pulsed at intervals 24, under the control of signals on the line 52. The resulting indications of thermal neutron concentration characteristic of the earth formation, produced by the detector 35, are transmitted over conductor 56 to the gates 57, 58 and 59. Subtraction of the background counting rate detected by the gate 59, in proportion to the length of the counting intervals 23 and 26, provides a net counting rate for each interval and the ratio, taken by the unit 65, after a selected count is attained in the second interval, is compared in the unit 66 with a desired ratio value thereby providing a measure of the rate of change of neutron concentration in the material. Any difference between these values causes the oscillator control unit 39 to correct the frequency of the variable oscillator 36 so that its period is equal to the thermal neutron decay time of the formations. The detector 35 may be sensitive to either thermal neutrons or gamma rays.

Abstract: 649,838. Cigarette lighters. SHAW, A. June 12, 1948, No. 15879. [Class 75(iii)] In a cigarette lighter having a removable torch comprising a fuel reservoir, a wick and high tension electrodes and insertable in a base or body part associated with a vibrator connected to a source of current and energized on closure of a normally open switch, the arrangement is such that the torch is connected to the vibrator only when it is in position in the body part. The apparatus comprises a torch 1 removably housed in a body part 2, a switch 16 and an electric vibrator, Fig. 4 (not shown) having a condenser 24 and primary and secondary windings 22, 23. When switch 16 is operated sparking occurs between a bridge piece 10 and a metal wick tube 6 to ignite the wick of torch 1. The torch, Fig. 3, comprises a metal or plastic container and insulating sleeves 8 and 12; the high tension current passes through the contact spring 15, the conductor rod 11, which is housed in the insulating bush 12, and union piece 14 to wick tube 6 housed in insulating bush 8 and sparks jump across to bridge piece 10 which is connected to the low tension side by the metallic sleeve 9, internal conductor rod 34 to the metallic sleeve 13 which rests on a shoulder in the base or body part 2. In an alternative arrangement, Fig. 7, depression of torch 1 operates a plunger type switch to complete the vibrator circuit through springs 108 and sleeve 106. The high tension current passes as before via an insulated rod 103 to the contact 102 at the bottom of the torch thus enabling sparks to jump between the wick tube 6 and a pair of discharge pins 100 and 101, Figs. 8, 9 (not shown). Sleeves 105 and 107 are insulating sleeves.
