IPC: F28D5/02
Filed: 1959-02-11
Abstract: 845,844. Refrigerating; gas cooling installations. GEA-LUFTKUHLER G.m.b.H. Feb. 11, 1959, No. 4828/59. Classes 29 and 64(3) An evaporative cooler, e.g. a refrigerant condenser or gas or liquid cooler comprises an upper pre-cooler 2 and a lower main cooler 4 over which water is sprayed from nozzles 10, the fins on the pre-cooler serving to separate water from the air stream being drawn upwards through the coolers by fan 15. As shown, pre-cooler 2 comprises parallel-connected pipes the fins on which are alternately inclined in different directions. The coolers are mounted in a shaft the lower end of which forms a water reservoir 11 which cools a further cooler 17 for the refrigerant and from which water is supplied to nozzles 10 by pump 8. In a modification, the coolers each consist of two series-connected banks of tubes, alternate banks being inclined slightly in opposite directions and the fins being perpendicular to the axis of the tube. Water is sprayed over both banks of the main cooler and the cooling air is forced upwardly through the coolers by fans mounted at the bottom of the shaft.

Title: Improvements in or relating to receivers for phase comparison radio navigation systems
Inventor: MARIE ALPHONSE PAUL EUGENE PIE
IPC: H03M1/00
Filed: 1967-02-01
Abstract: 1,149,824. Radio navigation. DECCA Ltd. 16 Jan., 1968 [1 Feb., 1967], No. 4899/67. Heading H4D. Specification describes phase comparison navigation receiver wherein phase discriminator outputs representing by amplitude and sign V Sin a and V Cos a, where α is the phase angle between two received signals, are converted into a digital representation of a, using a phase locked oscillatory " rotor " circuit (see Specification 873,999), to store a rotating vector have components, at the moment of phase locking, corresponding to said two outputs and a pulse counter which starts operating at said moment of phase locking and stops when said vector reaches a predetermined position, whereby the count is said counter represents a. The rotor circuit 30 comprises a closed 360- degree phase shift loop including two integrators 31 and 31a and an inverter 32. The phase discriminator outputs V 2  = V Cos α and V 1  = V Sin a are applied at time to via input resistors 60a and 60b, to integrators 31a and 31 respectively when switches 44 and 43 are closed. Decoupled feedback resistors 40, 41 and 40a, 41a are such that the output of each integrator becomes equal to the discriminator output applied to its input. Since each integrator introduces a 90-degree phase shift, the result is a rotating vector V, Fig. 4, in the rotor circuit, having components V 1  and V 2  at the outputs of integrators 31 and 31a at time to. Switch 45 gauged with 43 and 44 sets bi-stable circuit 48 at time to whereby ten stage counter 51 starts to count the output of generator 50 via opened gate 49. When detector 53 determines that the vector V has rotated through angle a (zero output from integrator 31) circuit 48 is reset and the counting operation ceases with a count, transferable to store 52 representing a. If the navigation system is the " Decca Navigator " type (" Decca " is a Registered Trade Mark) the three-phase comparisons between the Master station signals and each of the three slave stations signals will be at respective frequencies of 18f, 24f and 30f, such that equal phase differences in the three phase comparisons will represent different fractions of a zone corresponding to a comparison frequency f. Thus each phase difference must be divided in proportions to the comparison frequency to bring all such modified phase differences to the same scale. Therefore three monostable circuits 54, 55, 56 are provided having respective periods (much less than the period of generator 50), in the proportions 18 : 24 : 30. When that one of the monostable circuits corresponding to the comparison frequency being used is triggered by a clock pulse a switch 39, normally closed and inhibiting the operators of the rotor circuit, is opened, whereby the vector in the rotor circuit rotates for an incremental amount. Thus the vector will turn through angle α for less clock pulses at the 30f comparison frequency than at the 24f comparison frequency.

Title: Improvements in or relating to Ejector Apparatus.
Inventor: MELLERSH-JACKSON WILLIAM JOHN
IPC: F04F5/42
Filed: 1918-03-20
Abstract: 120,840. Jackson, W. J. Mellersh-, (Wheeler Manufacturing Co., C. H.). March 20, 1918. Addition to 114,134. Aspirating-apparatus, ejector.-The condenser air-withdrawing ejector described in the parent Specification is modified by making the member which projects, from cne of the disks of the nozzle, into a throat formed in the outer disk, of constant cross-section throughout a part of its length, and by rendering it adjustable with regard to the disk which carries it. Inducing-fluid, which may be live or exhaust steam, passes through a strainer (not shown) and a passage A to a throat T at which the cross-sectional area is a minimum, the throat being wholly within one of the disks C comprising the pair C, D that constitute the nozzle B. The combining cone or diffuser is formed by annular disk-shaped walls H, with a throat q, and delivers to a discharge passage and outlet (not shown), the induced fluid entering by inlets S giving access to the annular gap between the nozzle and the diffuser. A central member t projects into the throat from the opposite nozzle member B, and may be arranged solid therewith, so that it moves with the nozzle member as this is screwed to and from the opposing nozzle member to alter the width of the nozzle passage, and being of cylindrical shape over part of its length, the effective throat area is not changed by adjustment within the limits of the cylindrical portion, although it may be varied by adjustment beyond such limits. In the construction shown in Fig. 2, the central projection t is carried upon a stem g with a screw-threaded portion h adapted to take within the stem of the nozzle member D, which is itself provided with screw-threads s to enable the nozzle width to be varied. Lock-nuts d, j maintain the parts in position, and there is a screw cap over the heads of the adjustable parts. With this construction, the central member t is tapered, so that the area in the throat and the width in the nozzle may be adjusted independently. According to a modification of this arrangement, the movable nozzle-member D is curved at its centre to form a projection or bess, through which the projection t may be adjusted. The adjustable projection has a conical extremity to a cylindrical part, whereby it may be moved to alter the throat area; or, for a given throat, its position may be independent of the distance between the nozzle members.

Abstract: 556,781. Heel-attaching machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). April 16, 1942, No. 5021. [Class 17 (i)] Relates to machines for attaching a heel by a fastener driven through a hole in the last, and consists in providing the last with a shouldered bore, the, shoulder preferably being provided by a heel plate b and serving to support the last on a tube 20 providing a guide for a spidnle 24 driving the fastener N. Prior to driving the fastener pressure is removed from the shoulder to avoid damage to the shoe. The tube 20 is formed with a screw thread for a nut 40 urged upwardly by a torsion spring 50 and having ball-and-socket engagement with a member 92 supporting a plate 90 engaging the crown of the last. The plate is supported at its forward end by a second similar nut and mechanism. This last supporting gear is mounted on a plate 18 pivoted at 16 to the jack. The two nuts are formed at their peripheries with elongated teeth co-operating with pawls urged toward the nuts by springs and so positioned that as the last is swung about the pivot 16 to operative position, the nuts are turned by the pawls to lift the shoulder in the bore from the end of the sleeve 20. The tread abutment 108 and rear heel abutment 110 are carried by vertical slides with rack teeth connected by equalising pinions 112 loose on a spindle 114 guided for slight vertical play in slots 116. When both abutments have engaged the heel, the pinions are locked by a wedge 126 engaging complementary surfaces on the pinions. In a modification, the last support nearest the pivot 16 is omitted. In another modification, the nut and associated mechanism is omitted from the driver tube. Specifications 177,015, [Class 89 (iii)], 223,959, [Class 17 (i)], and 515,256 are referred to.
