Abstract: 737,505. Heating air. LUWA AKT.-GES. May 6, 1953 [Feb. 23, 1953], No. 12636/53. Class 64 (3). [Also in Group XL (a)] A device for influencing. the temperature of rooms, comprises a heat-exchanger in the form of a plurality of adjacent ducts, the wall temperature of which is influenced by a heating or cooling medium, each duct having an inlet for primary air, an inlet for secondary air and an air outlet, the hydraulic diameter of the duct not exceeding 60 mm. and its length being at least five times its hydraulic diameter, and the sum of the areas of the primary air inlets being less than one-fifth of the sum of the areas of the duct outlets, the arrangement being such that secondary air is entrained by primary air and, together with the latter, is passed through the ducts and is discharged from the outlets. The duct walls may be hollow as shown in Fig. 3 in which the ducts are formed by a hollow fluid carrying member I forming channels which are closed by dished plates 9, 10 to form the ducts 11, 12, for the mixture of primary and secondary air flowing through the duct, the primary air entering through nozzles 13 disposed at the lower ends of the ducts and inducing in the duct a flow of secondary' air. Alternatively (Fig. 6), a sinuous pipe 16 may extend through the duct walls which are thereby influenced by the temperature of a fluid flowing through the pipe. Ribs may be provided on the duct wall, Fig. 9 (not shown). Fig. 10 shows an arrangement in which an inlet funnel 34 of sound damping material extends for a short distance into the duct. A second funnel 37 is arranged at a short distance below the duct and the nozzle 35 by which primary air enters the duct is disposed in the mouth of the funnel 37. The distance by which the primary air nozzles 13 extend into the ducts may vary in adjacent ducts, Fig. 1 (not shown). This it is stated reduces noise. It is stated also that the heat exchanger functions as a convection heater when the primary air flow is cut off.. Dust may be extracted from the air flowing through the ducts by an electro-filter, Fig. 11 (not shown).

Abstract: 475,153. Mounting motors. THIRY, L. May 7, 1936, No. 12894. Convention date, May 21, 1935. [Class 79 (iii)] A resilient mounting allowing an internal - combustion engine substantial freedom to oscillate about a longitudinal axis, whilst restrainng other displacements and of the kind comprising rubber or like elements arranged in compression between engine and supporting frame parts disposed on either side of the median plane of the engine substantially tangentially to a circle or circles centred on the longitudinal axis of oscillation, is characterized by the use of rubber &c. elements of rounded form which, whilst absorbing engine oscillations of small amplitude by shear deformations are subjected to rolling deformation and displacement in the case of more extended oscillations. Springs or other elastic means not carrying any part of the weight are provided to assist in restoring the engine to its position of rest, being so selected as to avoid resonance effects. As shown, the elastic elements comprise cylindrical or ring like bushes 5, with rounded ends fitted in a radially compressed state between arms 3, on the engine, and tubular bracket parts 4 on the frame members, 2, 2<1>, the axes Y Y, Y<1> Y<1>, thereof being at right-angles to radii from the axis of oscillation O<2>. The elements 5 are adapted to " roll " without slipping between the engine and frame parts, being so dimensioned, with or without partial bonding, as to avoid complete inversion. Coil springs 6, 6<1> or blade or other forms of springs tend to keep the engine centralized. The constraining planes of oscillation of the supports may be inclined as shown in Figs. 4 and 5. In Fig. 4, the centralizing springs comprise rubber bands 9, 91 embracing lugs 10 on the engine and lugs 11, 11<1> on the frame. Either or both of the surfaces engaging the rubber elements 5 may be of concaved form as shown in Fig. 7, and shoulders 15 with buffers 16 may be provided to limit the oscillations whilst packing discs or rubber &c., may be employed at one or both ends of the hollow member 4 to exclude dirt &c. Fig. 7 also shows means for adjusting the inclination of the axis of the mounting the hollow member 4 in this case being on a base adjustably connected to the main part 1 by screws 12 in conjunction with spacing set screws 13 or a wedge 17.

As shown, the bronze, copper, chromium plated or stainless steel wire mesh 13 is clamped at intervals along its edges between channelled and ribbed bars 14, to the centres of which are screwed similarly shaped ears 18 carrying cross pins engaged by the ends of the leaf springs 22; the centres of the latter lie as shown behind further cross pins 21 held in lugs 20 welded to the strengthening channel 7. The spring tension is governed by the thickness or temper of the leaves, and/or by the number of such leaves inserted together in parallel relation at each suspension point. The sheet metal side plates 5 are welded, and the plates 6 screwed, to the channels 7; parts 6 may be, and parts 5 and 7 are, welded into rectangular frame form.

Title: Improvements relating to speed control systems for gravity operated railway marshalling yards

IPC: B61K7/12
Filed: 1954-05-04
Abstract: 756,499. Railway marshalling yards. METROPOLITAN - VICKERS - GES., Ltd., April 14, 1955 [May 4, 1954], No. 12973/54. Class 103 (1). In a brake control system for a railway marshalling yard a device Q, which continuously responds to the speed of a wagon in passing through a certain distance in a gravity sorting yard, gives a signal which operates a speed indicator S. The speed signal is passed to a converter C the output from which is made to vary with the square of the speed and is therefore a measure of the energy level of the moving wagons. The output from converter C is applied to the followers S1 and S2 which drive sliders S1 and S2 of variably tapped transformers U1 and U2. The connection to the follower F1 includes a back contact R1 operated by a relay coil R energized by closure of a track switch T1 until a normally closed track contact T2 is opened. Thus slider S 1 is adjusted to a position corresponding to the wagon energy level at T1. The position of slider S2 continuously represents the energy level of the wagon throughout the working distance. Thus the output E2 from transformer U2 and output E3 are increased by the amplifier AMP from the output voltage of transformer U1 or modified by a device TD which determines the distance to a wagon already in the siding, are used to energize coils W2 and W3 of an electromagnetic retarder control RC so that the position of an armature A is varied so that one or the other of relays O, L, M or H is energized to bring into action zero, light, medium, or high braking effect on the wagon. In another control circuit described, the output from the indicator S is passed to a rectifier and this is connected via variable resistors to the grids of two thermionic valves, one such connection being subject to closure by a switch moved by a wagon passing a predetermined point in the track. The amplified outputs from the valves are applied to two windings on a magnetic core so as to produce in a third winding a current or voltage representing the difference in the first two windings, and the output from the third winding is used to control relays such as O, L, M or H.
