IPC: F25B17/00
Filed: 1925-11-06
Abstract: 245,075. Mannesmann Kõlte Industrie Akt.-Ges. Dec. 24, 1924, [Convention date]. Refrigerating, absorption machines for. - The cooling-element for the generator-absorber vessel 1, Figs. 2 and 4, of a machine working on the reversing system consists of a number of straight tubes 16, 29, 30 extending through the end walls of the vessel and connected together and to the water supply and outlet tubes 15, 17 by external disconnectible couplings, whereby the tubes may be readily cleaned by brushes. Where an inner generator vessel 32, 33, Fig. 2, is employed, as described in Specification 241,279, the cooling tubes are located through it or near it. One tube 16 may be arranged in the vapour space, but near the surface of the liquor, while the others are submerged. The supply of cooling-water alternately to the condenser tank 3, Figs. 1 and 4, and to the generator-absorber 1 is effected by an oscillating vessel 21, Fig. 1, receiving from a fixed supply pipe 12, 20 and delivering to compartments 24, 25 leading respectively to a pipe 18 extending to the bottom of the tank 3 and to the pipe 15 connected with the pipe 16 of the generator-absorber. A thermal element located in a recess 5 in the generator-absorber actuates a diaphragm switch device 7 which controls the heating medium and rocks the oscillating vessel 21. The rectifier vessel 4, Fig. 1 ,is preferably partly submerged in and cooled by the condenser cooling water, and by arranging the outlet 19 of the condenser tank at the top there is ensured a reserve of cooling-medium for the condenser and rectifier in the event of failure of water supply. The water supply pipe 12 is fitted with a bent overflow pipe 27, through which the water escapes when the pressure is excessive, and the water spurts through a hole 28 to indicate the defect. The vapour passes from the generator through a pipe 8 to the rectifier 4, thence through a pipe 9, shut-off member 10 and pipe 11 to the condenser 26, and from the condenser to the evaporator through a pipe 36.

Abstract: 503,850. Bottling. WORSSAM & SON, Ltd., G. J., and FOX, D. P. S. Oct. 14, 1937, No. 27985. [Class 125 (ii)] Bottle-lifting mechanism for use in bottle filling machines of the circular revolving type comprises a two-stage bottle lift, the first stage being a quick-lift action, while the second stage applies seating pressure for fixing the bottle mouth tightly within the filling head. The bottle-lifting mechanism consists of a tubular member 1 slidable in a tubular guide 2 and carries a platform 25 in which is screwed a rod 24, encircled by a spring 28. A plunger 5 slidable in the member I is provided, at the upper end, with a hollow rectangular section extension 23, which receives the square head of the rod 24. The plunger 5 is connected by a gudgeon pin 11 and link 12 to a lifting arm 13, pivoted at 14 and carrying an anti-friction roller 21 bearing on an inner cam track 22. After a bottle has been placed on the platform 25 the cam 22 elevates the bottle lift and brings the bottle mouth into the appropriate filling head. Thereupon a roller 10 carried by the plunger 5 is operated by a short outer cam track 32 to apply the sealing pressure. A catch 30 engages a pin 9 on the plunger and retains the bottle lift in elevated position under scaling pressure. When the lift is to descend with the filled bottle the catch 30 is released. The position of the platform 25 relative to the lifting mechanism is adjusted by releasing the set screw 26 and lock nut 27 and turning the platform 25 on the screw threads of the rod 24.

Title: Arrangement provided with at least two combustion-type flash bulbs
IPC: H05B37/02
Filed: 1973-06-14
Abstract: 1433028 Flash bulb circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 14 June 1973 [17 June 1972] 28335/73 Heading G2X [Also in Division H2] A circuit for successively igniting flash bulbs 1-4 comprises a respective thyristor T1-T4 connected in series with each bulb and a control circuit for each thyristor, each control circuit including a winding W11-W41 of a respective magnetic core K1-K4 which has a rectangular hysterises loop and two stable remanence states. Initially a switch 18 is closed causing a switch 18a to open and triggering a thyristor 16 so that a capacitor 15 to discharge through a winding N1 of a magnetic core G. The remanence state of the core G is therefore changed, inducing a voltage in a winding N3, which voltage is fed via a diode 10 to windings W13-W43 on the cores K1-K4 and "resets" the cores. The switch 18 is then opened thus closing the switch 18a and a switch 23 is closed so that a capacitor 22 discharges through windings W12, N2 thereby reversing the remanence state of the core G and setting only the core K 1 in a suitable remanence state. When a camera flash switch is operated to close contacts 17, 19 the. thyristor 16 is again triggered so that the capacitor 15 again discharges through the winding N1, reversing the remanence state of the core G and causing another pulse to be fed to the windings W13-W43 However, only the remanance state of the core K1 is changed so that the pulse induced in the winding W11 triggers the thyristor T1 and the bulb 1 is therefore flashed. The bulb current flows through winding W22 of the core K2, setting this core in a suitable remanence state, and through the winding N2 to reset the core G to its original remanence state. A second operation of the camera flash switch therefore flashes the bulb 2. In a modification fire bulbs are sequentially flashed by a circuit including only three thyristors.

Title: Process for manufacture of artificial crystals
Filed: 1947-10-24
Abstract: Crystals are grown by immersing seed crystals in a super-saturated solution, but prior to the immersion of the seed crystals the surface of the solution is covered with a film of oil and the solution is subjected to mech <PICT:0650824/III/1> <PICT:0650824/III/2> anical vibrations of supersonic frequency so as to cause the formation of crystal nuclei around any suspended particles present in the solution, the nuclei are then separated from the solution.  The crystals grown by immersing seed crystals in the purified solution are free from flaws.  Ammonium dihydrogen phosphate (69.5 kg.) is dissolved in 100 litres of water at 50 DEG  C. in container 1; the solution is covered with a film 7 of oil, and stirred by propeller 2. The temperature of the solution is then reduced to 45 DEG  C. and submitted to a beam of supersonic waves produced by generator 3. When the density of the solution has become that of a solution saturated at 45 DEG  C., the generator and the propeller are stopped. The microscopic crystals which have been formed round the suspended particles fall to the bottom of the container, and are removed through stopcock 6.  The solution is heated several degrees to dissolve any remaining nuclei, and is then allowed to cool to 40 DEG C.  One or more seed crystals suspended by supports 9, are then immersed in the solution; and the stirring is resumed.  Four vertical, curved plates 10 are disposed in the container.  These plates cause accidentally-formed nuclei to fall into funnels 11.  The nuclei collecting in funnels 11 may either be withdrawn via stopcocks 13, or they may be redissolved by local elevation of the temperature of the solution in the funnels by means of heating elements 14.

Title: Computer.
Inventor: SIMMONDS DAVID THOMAS
IPC: G06F15/04
Filed: 1966-06-27
Abstract: 1,183,823. Calculators. NATIONAL RESEARCH DEVELOPMENT CORP. 21 June, 1967 [27 June, 1966], No. 28599/66. Heading G4A. A computer comprises programme control means, including a function code decoder utilizing electro-mechanical relays and switching means operable in response to jump and conditional jump instructions to cause jump. An electromagnetic-relay-type calculator is generally similar to that of Specification 1,183,572 which is referred to, except for the following. Programme control.-Each position of a 10- position wiper stepping switch can be plugged to up to 3 of 4 lines, in each of two such sets of 4 lines, to provide on the lines a 4-bit operation code having up to three 1s. A relay connects the two sets alternately to a relay register, the contacts of the relays of which form an instruction decoder. The wiper is advanced by one position every time a manual key is pressed, or advanced continually as long as a so-called " auto key " is held actuated. The wiper positions can also be connected by plugs to jump from", " jump to ", " stop " and " count " sockets, there being two of each type of socket, to correspond to the two sets of 4 wires respectively, and being operative only when their respective wire sets are connected to the instruction decoder. When the wiper reaches a position connected to a " jump from " socket, then if a " conditional jump " switch is in one state, the wiper steps quickly on until it reaches a position connected to a "jump to " socket, the computer not performing the instructions between. On the other hand, if the " conditional jump " switch is in its other state, this only occurs if the high order carry from the adder has the particular value which in the case of subtraction indicates a negative result. The computer stops at a wiper position connected to a " stop " socket (unless this position is being jumped over). A counter counts programme steps whose wiper positions are connected to " count " sockets.
