Filed: 1968-10-03
Abstract: 1,212,787. Cutting by fusion. MESSER GRIESHEIM G.m.b.H. 3 Oct., 1968 [5 Oct., 1967], No. 47029/68. Addition to 1,205,616. Heading B3V. [Also in Division F4] In a method of flame cutting a kerf of predetermined depth in a workpiece as claimed in the parent Specification, the heating gas is supplied to the torch nozzle unilaterally or eccentrically with respect to the cutting oxygen. A cut is formed using a torch nozzle with the cutting oxygen bore 10 disposed eccentrically in relation to the heating gas passage 12. A torch having five such nozzles fed from single cutting oxygen and heating gas inlets (14) and (16) (Fig. 5, not shown) may be used to form a J-shaped cut. The torch nozzles are arranged obliquely with respect to the direction of advance of the torch, the cut edge position 20 or 21 being determined according to the number of nozzles in operation. The cut edge position can be varied by rotating the torch. A slit nozzle may alternatively be used having heating slits disposed only on one side. A conventional nozzle may be used with some of the heating gas openings closed.

Abstract: 472,576. Radiators for aircraft. SOC. ANON. DES APPAREILS G. A. L. Nov. 25, 1936, No. 32317. Convention date, Dec. 24, 1935. [Class 29] A radiator of variable size for aeroplane engines comprises identical interchangeable elements 1<1>, 1<2>, 1<3> including a network of radiant hollow strips and placed one behind another, each constituting a complete assembly with liquid inlet and outlet manifolds with tubular extensions parallel to the direction of motion and means for attachment to adjacent elements. The elements may comprise two lateral inlet headers 1, 2, and a central outlet header 3 with parallel hollow strips 4 between them alternating with spaces 5 for the cooling air current. An upper tube portion 8 of each header is connected to the corresponding portion of an adjacent element by a socketed joint, the tubes being connected together by cross pieces 9. The tubes of one of the elements carry inlet and delivery tubes 16, 17, 18. The strips 4 are cross-braced by tubes 22 engaging corresponding tubes of an adjacent element. The radiator assembly is locked by stays 14 and nuts 15 screwed against plugs 13 closing the tubes of the end elements, by similar stays in a discharge pipe 19, and by external rods 21 at the lower corners. Filters 23 may be located in the tubes, e.g. the outlet manifolds 8. The Specification as open to inspection under Sect. 91 describes also a modified element comprising upper lateral inlet headers and a lower central outlet header with a honeycomb-type tube nest. This subjectmatter does not appear in the Specification as accepted.

A coin separating and counting device has a member 5 which carries means 12, 13 for operating a counting mechanism and which is radially-adjustable, as by slotted bolt holes 6, on a fixed circular sizing plate 1 so that the size of the apertures 3 in the plate can be altered for accepting differing descriptions of coins. In operation, coins to be sorted according to size are picked up from a hopper by an inclined rotary disc which directs the coins through a dividing plate into gaps formed between the teeth of a toothed wheel. Each coin 18 is then progressed by the wheel across the apertures 3 in the sizing plate, starting with the narrowest and ending with the widest. When a coin reaches an aperture of the size to accept it, it adopts the inclined position shown in Fig. 2 and operates the actuator 12 of a micro-switch 13 for the counter before falling through the plate 1 and a corresponding shoot disposed below; the actuator 12 is carried by a triangular plate 10 which is rotated about a pivot pin 8 against the action of a spring 15 when struck on its roller follower 9 by the coin.

Abstract: 1,103,759. Controlling tyre pressure and indicating deflation. SCOVILL MANUFACTURING CO. 17 Nov., 1965 [21 Jan., 1964], No.. 48864/65 Heading B7C. A tyre pressure control means and deflation indicator comprises respectively normally open and normally closed pressure-operated switches 23, 20 connected together and to a transistorized flasher unit 25 and batteries 26 to operate a flashing light 24 when pressure in any of the tyres falls below a predetermined minimum. On partial deflation of any tyre, air flows to the tyre from a pressure air source 14 via a valve 17 preventing fall of pressure in source 14 below, say 60 p.s.i., and a regulator 19 which controls tyre pressure. The switch 23 is closed and the switch 20 held open by flow of air from valve 17 and regulator 19 respectively until the pressure of air from the regulator falls to 10 p.s.i. below normal tyre pressure, whereon switch 20 closes and the light 24 flashes. As shown, source 14 is an emergency air brake tank of a trailer so that the light 24 will not flash when the vehicle is parked without air supply. The regulator 19 is in fluid communication with the tyres by a conduit system including the hollow, non-rotary wheel axles 12, 12a and rotary hub cap units 48 (see also Fig. 5, not shown).

Abstract: 1,085,707. Function generation. SETPOINT Ltd. Dec. 9, 1965 [Dec. 14, 1964], No. 50893/64. Heading G4A. An approximation to a non-linear function (Fig. 2) is generated by repeatedly adding to the content of an accumulator a predetermined number so that the content of the accumulator varies in accordance with a linear function and changing said number in. predetermined manner so that a series of linear functions approximating to said non-linear function are thereby generated. As shown (Fig. 3), an accumulator CA is arranged so that every time a pulse P is received from pulse generator PG a predetermined number X from the matrix store M is added to its content. Overflow signals O from accumulator CA are passed to binary counter BC and to counters D 1 -D 3  the outputs of which latter counters give the approximated value of N in the equation N = f(K) where K equals the value of the pulse counter PC. Overflow signals from counter BC are arranged by way of a control circuit CC to step-on a ring counter RC which selects which of the plurality of numbers X stored in matrix M is to be added-in to accumulator CA. The binary counter (BC) is pre-set to different starting values x from matrix (M 2 ) whereby the intervals at which the value of X (in matrix M 1 ) is changed may be varied. In a modification (Fig. 5, not shown), the binary counter (BC) is arranged to be operated by the pulses K directly whereby, the predetermined changes in the number X take place at (variable) intervals selected along the x-axis, rather than the y-axis as in Fig. 2. The matrix stores may comprise co-ordinate arrays of conductors with diodes at selected cross-overs. An arrangement to reduce disturbances due to noise is disclosed with reference to Fig. 4 (not shown). A simplified arrangement (not claimed) is described (Fig. 1, not shown), wherein the second matrix M 2  is omitted.
