Title: Heat exchangers
IPC: F28F3/14
Filed: 1974-04-11
Abstract: 1469705 Making heat exchangers CIBAGEIGY AG 17 March 1975 [11 April 1974] 16126/74 Heading B3A [Also in Divisions B5 and F4] A method of making a heat exchanger consisting of a conduit having a plurality of passes joined by integral return bends comprises stacking at least four pairs of strips of material together so that each pair is displaced laterally with respect to an adjacent pair, bonding the strips together to form a flat serpentine conduit, and inflating the conduit by internal pressure. The material may be copper, mild steel, aluminium, or aluminium alloy. The strips may be bonded by welding, soldering, or brazing, using a release agent or stop-weld in those areas which are to be inflated. The strips may be bonded by a thermosetting adhesive, e.g. epoxide resins and phenolic resins, and the latter may contain an elastomer such as nitrile rubber, or a thermoplast such as nylon or vinyl polymer. Alternative adhesives are natural or synthetic rubbers such as chlorinated, nitrile, or polysulphide rubbers, or thermoplastic adhesives such as poly - (vinyl acetate), poly - (vinyl chloride), polyacrylates, and polyamides. Fig. 2 shows part of a stack of strips, of which strips 21 have adhesive applied or lack stop-weld round three edges, and strips 22 do so at one end. The outer end of each strip is folded back, so that when the stack is compressed to cause bonding along the strip sides and at 31, 32, Fig. 3, uniform thickness of the stack is ensured in the region of the return bends. Alternatively, separate packing pieces may be used. Heat may be applied during the compression. The resulting stack may be cut to produce a serpentine conduit of the required size, which is then interleaved with tool pieces 51, Fig. 5, and connected at one or both ends to a source of air or water under pressure. The pattern of adhesive or stop-weld may be such as to produce a single channel along the strip, or plural channels, or plural interconnected channels, or a channel may be sinuous. In a final step, fin pieces are placed between the passes and fixed by adhesive. Alternatively these may be inserted before inflation of the conduit, and gripped by such inflation. The completed heat exchanger may be coated against corrosion by dipping in an organic medium containing metallic particles.

Abstract: 577,844. Control systems for resistance welding. GLEDHILL, F. G., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 28, 1944, No. 16331. [Class 38 (iv] A resistance spot welding device having a timing circuit comprising a timing capacity 11 progressively charged until terminated by a discharge device 15, and a variable resistance 13 for controlling the charging rate, is characterised by the connection across the timing circuit of a potentiometer 9 which may be adjusted so that similar settings of the resistance 13 will give the same lengths of weld independently of the characteristics of the discharge device. Closure of a main contact 4 energises the timing, circuit and a circuit for a relay coil 7, which closes a contact 7A in the main welding circuit and opens a contact 7B in the circuit of a condenser discharging resistance 16, thus simultaneously initiating the charging of condenser 11. When the discharge device 15 " fires," a coil 14 of a relay in series therewith is energised to open a contact 14A in the circuit of coil 7 and a contact 14B in the circuit of resistance 16, thereby stopping the weld. Welding cannot be resumed until main contact 4 has been opened, since the relay 14 is maintained energised. Contact 4 may be closed manually or by movement of the welding jaws. The method of adjusting the potentiometer when the discharge tube 15 is changed is described.

Title: Apparatus for playing a table game
IPC: A63F7/02
Filed: 1933-06-07
Abstract: 411,290. Coin - freed game apparatus. PARKER, W. H., 20, Market Place, and KENTISH, W., 93, Heath Street, both in Hampstead, London. June 7, 1933, No. 16362. [Class 27.] The invention relates to a billiard or bagatelle table having scoring openings such as 3, 4 ... 10, and runways 15, Fig. 3, under the table leading from the openings to corresponding scoring pens 16 from which the balls may be taken for replay. According to the invention a coin-freed shutter 17 is operated after a predetermined time to trap the balls in the runways 15 as shown in Fig. 4. The playing surface 1 may be provided with a baulk line 11 and spots 12, 13, 14 on which balls and obstacles such as skittles are placed. Coin-freed mechanism. To release the balls for further play a coin is inserted in a slot 33, Figs. 1, 5, 6, and a rod 18 retracted against the action of a spring 24. The coin is prevented from falling through the slot 33 by a spring biassed pin 34 slidable in the rod 18 which is normally locked against retraction by a sprung stop member 37 engaging a notch 36 therein, but is released by the coin edge engaging and retracting the stop. During retraction of the rod the pin 34 engages a fixed inclined surface 42 and is moved axially thereby until a slot 35 in the pin aligns with the slot 33 and allows the coin to fall through into a receptacle. A plunger 19 is fitted in the inner end of the rod 18 to which is pivoted a catch 23 biassed by a spring 25 anchored to a bar 26 rigid with the rod 18. When the rod is retracted, a flange on the plunger prevents retraction thereof, the catch 23 engages a notch 21 in the plunger and the end 23<a> of the catch engages and retracts a rack 30 geared to a clockwork mechanism 32 which is thereby wound. A pawl 44 pivoted to the rod 18 coacts with a notched member 43 to ensure sufficient retraction of the rod. When the rod is released the plunger 19 is projected and rocks the pivotal member 20 which rocks the shutter 17 to the open position. The clockwork mechanism 32 now advances the rack 30 through pinion 31 until the adjustable bolt 29 engages the end 23<a> of the catch 23 and trips it thereby allowing return of plunger 19 to the position shown under the action of a spring or the weight of the shutter 17.

Title: Improvements in and relating to the production of electrical oscillations by means of thermionic valves
IPC: H03C1/22
Filed: 1920-06-19
Abstract: 169,250. Radio Communication Co., Ltd., and Lea, N. June 19, 1920. Thermionic oscillation generators; thermionic modulating apparatus. - The amplitude of the oscillations emitted by a valve generator is controlled by means of a two-electrode valve in series with a source of variable electromotive force, both elements being shunted across the grid and filament of the generating-valve in order to prevent the grid potential of the generating-valve from exceeding a predetermined value. The anode circuit of the triode 1 is supplied by a source 3 of direct current. The grid circuit includes a resistance R, an inductance L coupled to the output coil 4, and a battery E. The plate circuit of the control diode 2 contains a variable source of potential e, the plate potential relative to the filament being maintained normally negative owing to the superior voltage of the battery E. When, during action, the voltage of the grid of the generator 1 builds up to such a value as will throw the plate a of the diode positive, the latter will start to conduct, thereby setting-up rectified pulses of highfrequency current in the circuit R, L which prevent any further increase of grid potential. By suitably varying the value of the battery e, the amplitude of the output can be correspondingly controlled. In Fig. 3, A‹ represents the normal amplitude of the oscillations generated by a valve bearing the characteristic shown, whilst B‹ is the reduced oscillation corresponding to a value e of the variable source shown in Fig. 1. By using a constant source e in series with a microphone secondary, the arrangement can be used for wireless telephony.
