Abstract: 823,486. Land mines. SOC. MINELBA S.R.L. Nov. 15, 1957 [Nov. 16, 1956], No. 35584/57. Class 9(2) Land mine comprises a cylinder 1 open at the top to receive with sliding fit a similar but inverted cylinder 2 which is closed by a cap 3, separated from the base of cylinder 1 by an air cushion 9. The cap 3 has acentral orifice from which a tube 7 extends into a recessed piston 5 carrying a firing pin 12 and having sliding fit in a tube 4 coaxially secured to the cap 3.

Title: Improvements in or relating to continuous absorption refrigerating apparatus
IPC: F25B15/10
Filed: 1933-12-19
Abstract: 411,391. Refrigerating. HOOVER, Ltd., Perivale, Greenford, Middlesex.-(Hoover Co. ; North Canton, Ohio, U.S.A.) Dec. 19, 1933, No. 35732. [Class 29.] Absorption systems.-The refrigerant vapour is brought into contact with the liquor in the absorber in a number of stages, and the liquor is circulated from one stage to the next through cooled piping extending outside the absorber proper. By this means extensive air-cooled surfaces for the liquor are provided while the dimensions of the absorber proper are kept small. In a continuous-cycle inert gas system as shown, comprising a generator B, gas separator D, rectifier and liquor receiver F, condenser C, evaporator E and gas heat exchanger H, the absorber A receives weak liquor through a pipe M<2> entering it at the top and a mixture of refrigerant and inert gas entering through a pipe H<4> at the bottom. The absorber is fitted with a number of shallow trays N' ... N<4> having drain pipes P <1> .. , P<4> fitting one within another and communicating with air-cooled external pipes R<1> ... R<4>, which return the liquor to a series of baffles O<1> ... O<4> between the trays. The strong liquor leaves the absorber at the bottom by a pipe A<2> passing through the liquor heat interchanger M to the receiver F, from which the generator B is supplied by pipe F<3>. A conduit E<4> returns unevaporated refrigerant from the evaporator to the rectifier, and a pipe H<5> drains any liquor from the gas heat exchanger to the liquor heat exchanger. An auxiliary heated generator J receives a part of the condensed refrigerant from a gas-liquid separator G, and vapour generated therein is led to a nozzle K in the inert gas conduit E<2> from the evaporator, to promote gas circulation. Alternatively the gas nozzle may be fed from a generator supplied with liquor. The invention may be applied to non-condensing systems, such as those described in Specifications 250,593, 251,251, and 269,564, [all in Class 29].

Abstract: 510,499. Apparatus for pasteurizing liquids in bottles or other containers. HANSEN, C. S. Dec. 8, 1938, No. 35797. [Class 49] In apparatus for pasteurizing beer, milk or other liquids in bottles, cans or like containers, the containers are taken by a conveyer 7 on which they stand freely or in low holders through a preheating zone 1, 2 in which they are sprinkled with preheating liquid, a pasteurizing zone 3 in which they are sprinkled with and immersed in heating liquid, and a cooling zone 4, 5, 6 in which they are sprinkled with cooling liquid, the preheating and cooling zones being arranged with a variation of temperature such that gradual heating and cooling of the containers is obtained. As shown, the apparatus is provided with sprinkler pipes 12 for supplying the heating or cooling liquid and the preheating zone includes two chambers 1, 2 in which the water used for sprinkling is kept at about 35‹ and 50 ‹C. respectively and the cooling zone chambers 4, 5 with the water at about 50‹ and 35‹C. respectively and a chamber 6 with cold water. A common circulating pump may be employed for chambers 1, 5 and another for chambers 2, 4 to effect heat exchange, the chambers being additionally provided with means for supply of steam or water for regulating the heat, the water collected in-chamber 6 being employed. In the pasteurizing chamber 7 the water is at about 60-70‹C. The slope of the conveyer in chamber 7 does not exceed 14 degrees to prevent the containers sliding thereon.

A structure for use as a computer element consists of a plurality of narrow drive conductors 11 lying on one side of a sheet 10 of insulating material, while on the other side of the material is at least one sense conductor 15, and the structure is characterized in that the narrow drive and sense conductors are widened at some overlying positions 12 so as to form capacitors at these positions. Such an element with one sense conductor capacitively connected with each of three drive conductors may be used as an OR gate for pulse signals on the three drive conductors. The same arrangement may be used as an AND gate for positive pulse signals on two of the drives by applying a negative control pulse on the third drive. Complex gating arrangements may also be developed. A structure according to the invention may be used as an encoder by providing a number of sense conductors and establishing capacitive connection between them and the drive conductors at certain specified positions such that a binary coded output is obtained on the sense lines when a given input drive line is pulsed.

Abstract: 755,409. Push-button lifts. NAAMLOOZE VENNOOTSCHAP MACHINEFABRIEK DER FIRMA P. M. DUYVIS & CO. Dec. 10, 1954, No. 35890/54. Class 78 (3). A lift control circuit has means for copying the position of the cage comprising relays which are successively energized as the cage moves in one direction and are successively deenergized as it moves in the reverse direction. " Up " and " down " contactors U and D are controlled by buttons K1-K4 in circuit with the bottom contacts of relays 1bo, 2on, 2bo, 3on, 3bo and 4on, which relays form the movement copying device. These relays are successively energized from left to right during upward travel of the cage and vice versa during lowering, by change-over switches I, II on the cage, which alternately engage projections secured in the shaft at each floor level, and by groups of contacts HNI, II, which are open when the " down " contactor is energized, and HOI, II which are closed when the " up " contactor is energized. The contactor control circuit is thereby conditioned so that when the cage is below any floor, operation of the button associated with that floor actuates the " up " contactor, and vice versa. Means are provided to return the circuit to synchronism with the position of the cage in the event of a power failure de-energizing all the relays with the cage away from the ground floor. In a modification (not shown), the switches I, II and shaft projections are replaced by non- mechanical induction switches.
