Title: Improvements relating to rotary coolers and like apparatus
IPC: F28C3/18
Filed: 1945-10-26
Abstract: 603,654. Cooling granular &c. materials. SMIDTH & CO., Ltd., F. L. Oct. 26,1945, No. 28362. Convention date, Nov. 9, 1944. [Class 64(ii)] [Also in Group XII] A rotary cooler, including a rotary shell into which air must be introduced during operation, is characterised in that a fan or the like for supplying the air is mounted on the shell and connected to a windbox which encircles the shell and from which the air passes through the shell by one or more openings in its wall. In a cooler shown applied to a rotary cement kiln, motor driven fans 29 supply air to an encircling windbox 20 from which damper controlled ducts 31 discharge the air below inclined grates 32. Spring loaded arms 42 normally maintain the dampers in a closed or almost closed position, but contact of said arms with an adjustable cam track 44 ensures admission of air through the cylinder. A modification is described in which cooling chambers are disposed circumferentially of and parallel to the outside of the shell, and in this case the chamber containing the fans and motor lies parallel to and between two of the cooling chambers.

Filed: 1975-07-04
Abstract: 1517213 Seaming non-metallic sheet material GD SpA 4 July 1975 [10 July 1974] 28379/75 Heading B5K A device similar to that described in Specifications 1,517,211 and 1,517,212 is provided with means for preventing the seaing member 29 from scorching the thermoplastic wrapping material when this member has been put back into operation, after having been taken out of operation due to the slowing down of the operating speed of the machine. When out of operation, the member 29 becomes overheated due to heat inertia. When the member 29 is put back into operation and overheating is sensed by means (not shown), an electromagnet 65 is energized to cause the cam 14 to slide on the shaft 12, splined at 62, so that the roller 24 engages a second cam track 14a adjacent the cam track 14 so that the dwell time of the member 29 in contact with the packet P is shorter than that when the roller 24 engages the track 14. When the temperature of the member 29 has reached its normal operating level, the electromagnet 65 is deenergized and the track 14 is positioned under the roller 24.

Abstract: 699,749. Copy - grinding. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Nov. 20, 1951 [Nov. 23, 1950], No. 28652/50. Class 60. [Also in Group XIX] In order to overcome difficulties arising from backlash in copy-milling machines of the type shown in Fig. 1 in which a model t is reproduced to a reduced scale on a workpiece U a dummy workpiece U' specially finished by hand to the required shape is substituted for the ordinary workpiece and the tracing process is repeated back through the machine to the model t which is then corrected accordingly. The dummy workpiece U<SP>1</SP> is shown in Fig. 2 and is arranged to form part of an electric circuit for indicating when contact is made or broken between a special tracing member X mounted on an insulated bearing X<SP>1</SP> on the cutter shaft C'. The tracing member x is substituted for the usual cutter C shown in Fig. 1. A special tracer wheel d<SP>2</SP>, Fig. 2, is substituted on the tracing arm a for the regular wheel d shown in Fig. 1. The wheel d<SP>2</SP> is provided with a cutting surface d' which may be rotated by hand to correct high spots in the model t. In use the model t is made to approximately correct shape and the dummy workpiece U<SP>1</SP> is made exactly as the final workpiece is required. The wheel d<SP>2</SP> is traversed over the surface of the model t and the slight eccentricity inherent in the mechanical mounting of the tracer wheel x causes flashing of the lamp Y<SP>1</SP> as the contact between U<SP>1</SP> and x is lightly made. If the model t deviates from the dummy workpiece U<SP>1</SP> the wheel x will be lifted and the indicator light Y<SP>1</SP> will go out indicating a high spot on the model t which may then be removed by hand finishing, or with the aid of the cutting surface d' of the tracer wheel.

Abstract: 598,683. Concrete blocks. MALTHOUSE, E. G. Oct. 31, 1945, No. 28849. [Class 87(i)] A prefabricated concrete corner unit is formed by casting a concrete slab with a row of cavities extending across it, erecting the slab, when set, at a desired angle to the horizontal, and casting a second slab in such a way that material for the second slab enters the cavities of the first slab to unite the two slabs. A concrete slab 28, Fig. 1, is cast between a toothed member 24 and a stepped member 26 on a template 20 with upstanding ribs in simulation of brickwork. The concrete is poured in the mould after L-shaped reinforcing bars 29 have been laid and a bar 32 has been passed through holes in the toothed member 24. The finished block 28 is removed from the mould after withdrawing the bar 32 and is placed upright against a support 36, Fig. 3, with its toothed end on the template 20 of a mould similar to that shown in Fig. 1. Concrete 40 is introduced to form a slab filling the cavities between the teeth of the slab 28 to which it is keyed by the reinforcement 30 and by a bar 41 previously inserted through the holes in the teeth. In an alternative construction, the first pre-cast slab 46, Fig. 6, is formed with upstanding teeth 47 having protruding reinforcing bars 48 between them. In a further construction the second slab is cast to extend on both sides of the teeth of the first slab to form a T-unit. Alternatively a T-unit may be produced by uniting the second slab through cavities formed in an intermediate part of the first slab; and by uniting an intermediate part of the second slab with an intermediate part of the first slab an X-unit is produced. Specification 573,233 is referred to.

Filed: 1935-10-19
Abstract: 464,483. Television. RADIOAKT.-GES. D. S. LOEWE. Oct. 19, 1935, No. 28905. Convention date, Oct. 25, 1934. [Classes 39 (i) and 40 (iii)] Image and synchronizing signals are derived from a single photoelectric cell 12, and the synchronizing signals are of such amplitude as to reduce to zero the current in the last stage 15 of a common amplifier 14. The imagechange signal is produced by a slot in the scanning-disc 17, which has a length corresponding to one scanning-line and a width equal to that of several scanning-apertures, Fig. 2 (not shown). A disc carrying a double spiral of apertures is used and has two synchronizing slots, staggered to the extent of one or more scanning-lines. To generate line synchronizing signals a white edge to a projected image 1<1> of a film 1 is obtained from the light 5, which illuminates the film, by means of reflecting-prisms 7, 8. Alternatively the white edge is derived from a special light source. The light sources are incandescent projection lamps fed from alternating-current mains through polyphase rectifiers and smoothing-circuits. The amplitude of the image currents is controlled by a diaphragm 16 in the path of the rays which illuminate the film. Receiver. A special electrode 22, separate from the main controlling-electrode 21, is placed in a cathode-ray tube to cut down the ray during the return movements. The necessary potentials are derived from secondary windings 29<1>, in series or parallel, of push-pull transformers 29, 37 in the anode circuits of push-pull amplifiers 30 fed from relaxation oscillators. The valve 40, for separating the large, positive synchronizing- signals, is mounted in the same envelope as the detector 26, an auxiliary cathode is provided, and the anodes are connected together inside the envelope, Fig. 4 (not shown).
