Title: Strip clamp assembly
IPC: B23K9/025
Filed: 1966-06-08
Abstract: 1,109,338. Strip-joining apparatus; shearing; welding. GUILD METAL JOINING EQUIPMENT CO. 8, June 1966 [8 April, 1966], No. 25571/66. Headings B3A, B3R and B3W. A strip-joining apparatus includes a stripclamp assembly comprising a frame 2, a first fixed strip clamp 20, a second movable strip clamp 21 and a pair of shear block assemblies 35 and 36, the second strip clamp 21 being moved toward the shear block assembly 36 subsequent to shearing of the strips to expose the end of the strip B and the clamp 21 and both the shear block assemblies 35 and 36 then being moved as a unit to expose the end of the strip A and to position the strip ends a predetermined distance apart for welding. The clamp 21 includes a platen 23 and a clamping beam 25 which is actuated by a fluid cylinder. The clamp is slidable on a plate 30, its movement being limited in one direction by a flange 43 on the plate and in the opposite direction by abutment with the shear block 36. The clamp is moved by a fluid cylinder 45. The plate 30 which also carries the blocks 35 and 36 is slidably mounted on frame 2 and its travel is limited in one direction by a stop 40 and in the opposite direction by an adjustable stop screw 51. The other clamp 20 is fixed on the frame 2. The shear block 35 pivotally supports an arm which carries a back-up bar 48. As the shear block 35 is moved to the left the tail of the arm engages a cam 57 which rotates the arm to bring the bar under the adjacent ends of the strips. Operation.-Strips A and B are gripped by the clamping beams 24 and 25 and the ends overlapping the shear blocks 35 and 36 are cut off by rotary shear blades 39. The cylinder 45 is actuated to move the clamp 21 to the left so that the freshly-cut end of the strip B overhangs the block 36. When the platen 23 abuts the shear block 36, both the shear blocks are then moved to the left so that the strip A overhangs the block 35. The position of the screw 51 determines the gap between the strip ends. The shearing cutters 39 are mounted on a carriage which is traversed across the strip in the shearing operation and which also carries a seam, spot, stitch, gas or flash-butt welding head. Welding is effected on the return traverse of the carriage. In a modification the gap between the strip ends is determined by placing a shim between the block 36 and the platen 23.

Title: Method and system for utilising tidal energy
IPC: F03B13/26
Filed: 1936-09-21
Abstract: 487,850. Utilizing tidal energy. CAQUOT, A., and DEFOUR, A. Sept. 21, 1936, No. 25668. Void. Convention date, Sept. 26, 1935. [Class 69 (i)] The invention relates to methods of obtaining energy from tides in which water impounded in a storage bay as the tide rises is delivered to turbines, the tail water from which is passed to a drainage bay which is emptied into the sea at low tide, and consists in increasing the available head for operating the turbines by pumping water to the storage bay and from the drainage bay at certain parts of the cycle of operations. Fig. 1 shows the cycle, the upper, middle, and lower curves showing respectively the level of water in the storage bay, the sea, and the drainage bay. Commencing at the left-hand point N on the upper curve, the storage bay supplies the turbine, until the level of water in it becomes equal to that of the tide at C. The storage bay is then cut off from the turbine and from C to I is filled from the sea. At I, just after high tide, the storage bay is cut off from the sea and filled by pumping to the level K. At the point L it is again connected to the turbines, which it continues to supply until the level in it has again fallen to C. During the period C to L, represented by a broken line portion of the upper curve, the turbine is supplied directly from the sea. Considering now the lower curve, from P to F the tail water from the turbines flows into the drainage basin, the water level in which rises until at F it is equal to that of the tide. Here the tail water from the turbines is delivered direct to the sea, and the drainage bay is emptied into the sea until just after the point of low tide A, when it is cut off from the sea and pumped out to a level O. At the point P it again receives the tail water. The tail water from the turbines is delivered directly to the sea during the period F to P represented by a broken line on the lowermost curve. The method is stated to enable smaller turbines to be employed and greater power to be obtained. Fig. 2 shows diagrammatically an arrangement of bays and turbines for use by the method, in which the power-house Z is arranged between a receiving bay A<1> and tail bay D<1>. The receiving bay is fed through valves B<1>, C<1> either from the sea W or from the storage bay Y, and the tail bay discharges through the valves E<1>, F<1> to the sea or the drainage bay X. The storage and drainage bays are connected to the sea through the valves G<1> at the appropriate times.

Patent GB-232277-A (GB)
Title: Improvements in or relating to the manufacture of resinous materials
IPC: C08G8/28
Filed: 1923-10-18
Abstract: Resinous materials are produced by treating with an aldehyde the product of interaction of acetylene and a phenol.  Preferably acetaldehyde or one of its polymers, such as paraldehyde is employed as the aldehydic body, but formaldehyde, trioxymethylene, paraformaldehyde or furfuraldehyde may also be used; phenol, cresol and naphthol are mentioned as phenotic bodies.  The sulphuric acid and mercury sulphate required to effect the interaction of acetylene and the phenol serve to catalyse the main reaction; a sulphonic acid such as benzenesulphonic acid may also be added for this purpose, whilst excess of the acidic catalyser may be removed by adding aldehyde ammonia.  The reaction product is a liquid which on gently heating for some time, sets on cooling to a fusible and soluble mass. The liquid or solid product can be converted into an insoluble, infusible material by heating it under pressure, a hardening agent being added in some cases.  Hardening agents mentioned are hexamethylenetetramine, paraformaldehyde, a phenylenediamine, aldehyde ammonia, furfuramide and ethyllidene aniline.  Examples are given of the preparation of the fusible and infusible modifications. The products are useful in the manufacture of varnishes and lacquers and for the production of moulded articles. Specifications 183,830; and 227,216, [Class 22, Cements &c.], are referred to.

Title: Improvements in and relating to alarm clocks
IPC: G04B23/06
Filed: 1933-04-12
Abstract: 409,199. Alarm clocks. CLORIUS, A. V., 3A, Friserveg, Charlottenlund, Denmark, and BLIN, H., 119, Rue du Cherche-Midi, Paris. April 12, 1933, No. 26020. Divided on 407,543. [Class 139.] In a mechanical alarm clock, a signal disc 64 which initiates the signals is loosely mounted on its pivot and revolves only through a small angle. This slight movement takes place only at the signal times. A double circle of holes 66, 67 in the disc 64 receive the legs 65b, 65<c> of each trip member 65 used, the leg 65b coacting with the finger 72 on an arm 71 which rotates with the hour wheel 68. Pivoted at 70<a> to the clock frame 18 is an arm 70 which is pressed upwards by a spring 36<a> and is pivoted at A to an arm 69, which latter is pivoted to the signal disc 64 at 69<a>. Arm 70 carries stop plates 32, 35 which coact with a pin 10 on an anchor wheel 12 of the alarm train which rocks the usual anchor to oscillate the alarm hammer shaft 76. Rigid with this anchor and shaft is an arm 77 which coacts with a wheel 75, which is rigid with the minute wheel 74 and has twelve cuts 75<a> so that the signal is finally released at exactly the end of a fiveminute division of the hour. The finger 72 is pivoted at 72<a> to the arm 71 and controlled by a spring 73 and a further piece 72<c> is pivoted at 72b to the finger 72 and controlled by a spring 73<a>. The piece 72<c> is to allow the hands to be set backwardly. The arm 71 rotates counterclockwise in Figs. 2 and 4, and when piece 72<c> meets the leg 65b of a trip 65 placed in the desired position, the piece carries the leg and disc 64 with it. Arm 70 thereby rotates counterclockwise about its pivot 70<a>, and pin 10 slips off plate 32 on to plate 35. As rotation of arm 71 continues and further rotation of disc 64 is prevented by a fixed stop (not shown), piece 72<c> wipes past the leg 65<b>, finger 72 moving against spring 73. Spring 36<a> then returns disc 64 clockwise and raises arm 70 so that pin 10 slips under plate 35 and wheel 12 rotates. As soon as wheel 12 turns, however, the end of arm 77 is moved by the anchor shaft 76 to engage the top of a tooth on wheel 75. At exactly the next five-minute period, arm 77 moves into a notch 75<a> and the alarm is given. Wheel 12 is driven by a spring and may have more than one pin 10 on it. In a modification, the plate 35 is omitted. Specification 407,543 is referred to.

Air is supplied from chamber 8 to a slot 30 to detach fuel from the surface 1b, a sharp edge 31 assisting the detachment. The chamber 8 is connected to the inlet through a passage 7 and the passages 9 may be arranged to cause swirling in the chamber 5. The needle 4 may be provided with sharp-edged recesses to prevent fuel sticking thereon. In Fig.3 a passage 16 feeding air to a slot 16a on the downstream portion of the surface into which the chamber 5 opens to detach any fuel film forming thereon, is connected to chamber 19 which is in connection with chamber 8 through a valve 17 which is open during normal running but closed by contact of the piston 2 with the stem 18 during idling. The float chamber may be connected to the carburetter suction space through a passage 21, Fig. 5, and the pressure in the float chamber controlled by a valve 37a actuated by the throttle valve 20 or by a suction actuated diaphragm. In Fig.7 (not shown), the needle (4<SP>11</SP>) projects downwardly from the jet (11) and is connected to the piston (2) by linkage (46), (45). The passage beneath the piston 2 at idling may be reduced by projections (47) in the bridge (1b), Fig.8A (not shown) mating with corresponding recesses (48) in the piston. In Fig.4 the undersurface of the piston 2<SP>1</SP> ends in a sharp fueldetaching edge 32 and detaching of any fuel film thereon is also assisted by air supplied through passage 34 to an orifice adjacent the edge 32. The passage 34 is closed at idling by a pin 36 projecting into a recess 35 which intersects the bore 34.
