Title: Improvements in or relating to welding control
Inventor: LEVINGE RODNEY WALTER
IPC: B23K11/25
Filed: 1968-07-08
Abstract: 1,256,096. Control systems for resistance welding apparatus. SOLARTRON ELECTRONIC GROUP Ltd. 2 July, 1969 [8 July, 1968], No. 32573/68. Heading H2H. In order to inhibit the discharge of molten metal from a weld in a resistance welding operation the resistance of the weld is monitored such that when the weld resistance suddenly undergoes a considerable drop-indicating that the weld interfaces have become molten-the supply of current to the weld is terminated. In order to monitor the weld condition a succession of first electrical signals are derived which are dependent upon the voltage across the welding electrodes, a succession of second signals being derived which are substantially unaffected by a change #S in the magnitude S of the first signals due to a change in the resistance of the workpiece during the welding process, the first and second signals being used to derive a succession of third signals such that a change #S in the first signals results in a change #T in the magnitude T of the third signals, the ratio #T/T being greater than the ratio #S/S and finally comparing each third signal with a preceding third signal and using the resulting comparison to terminate the welding current when the comparison between the third signals exceeds a predetermined amount. The apparatus may be used in conjunction with the apparatus of Specification 1,177,987 and the second signals may be made dependent on the welding current.

Title: Methods of and means for assembling electrode systems for electric discharge tubes
IPC: H01J19/46
Filed: 1947-12-10
Abstract: 655,312. Thermionic valves. PHILIPS ELECTRICAL, Ltd. Dec. 10, 1947, No. 32592. Convention date, Oct. 15, 1946. [Class 39 (i)] Concentric arrangement of cathode, grids and anode is obtained mechanically by feeding these electrodes successively into a series of movable guiding gauges arranged in pairs. Two or more such pairs may be used, the Figure showing three. Each pair, 1-2, 3-4, and 5-6 is mechanically controlled for lateral opening and closing. Initially, with all guides closed, the cathode sleeve is fed in at the top, and falls through the central grooves on to a locating pin 9. Guides 1-2 are then opened sufficiently to allow the first grid 12 to fall through and rest on the top of guides 3-4. Guides 1-2 are then closed and guides 3-4 opened, so that grid 12 falls further, guided by 1-2, to rest on the top of guides 5-6. Since grid 12 is longer than guides 3-4, its upper end is now accommodated in a recess 16 in guides 1-2. Guides 5-6 are now opened to allow grid 12 to fall, guided by 3-4, on to the mounting plate while simultaneously guides 1-2 reopen to admit the next grid 13, and so on. To facilitate the entry of the electrode support wires into the holes in the mounting plate, the jaws 7, 8 may be spaced slightly apart, or the holes may be tapered and the lower end of the wires cut obliquely. Suitable insulating members secure the electrodes in position after assembly. The grids may have cooling fins attached.

Title: Process for the treatment of alcoholic and non-alcoholic beverages
IPC: A23L2/56
Filed: 1957-10-18
Abstract: The taste and flavour of beverages e.g. wines, beers, whisky, ginger ale, carbonated non-alcoholic beverages, are improved by addition of glycine (glycocoll) and/or alanine to the finished beverage or, alternatively, in the case of non-alcoholic beverages to a liquid or solid concentrate adapted to be diluted with water to form the beverage.  The optimum proportion of glycine and/or alanine (which includes a -alanine and b -alanine) added is determined by taste experiments employing varying amounts, for instance 100, 250, 500, 750 and 1,000 milligrams, to 100 c.c. samples of the beverage, and is of the order 0.05 to 1.5%.  The compounds may be added to a must before fermentation and a further dose added after fermentation is completed.  According to an example, 100 gallons of whisky were improved by addition of 760 g. glycine and 95 g. alanine, the proportions having been determined by a series of taste experiments.

Title: Improvements in or relating to hydraulic shock absorbers
Inventor: NEWTON NOEL BANNER
IPC: F16F9/49
Filed: 1954-11-16
Abstract: 763,557. Hydraulic shock absorbers. NEWTON & BENNETT, Ltd. Nov. 16, 1955 [Nov. 16, 1954], No. 33096/54. Class 108(3). The invention relates to hydraulic shock absorbers of the type comprising a piston 12 carried by a piston rod 11 and operating so as to displace liquid in a cylinder 10. According to the invention, hydraulic stop mechanism for the piston 12 comprises complementary separable parts 16, 13, adapted in combination to form an auxiliary piston when brought together, the part 16 being attached to the piston rod 11 and the part 13 being resiliently supported in the cylinder away from but adjacent the relevant end thereof. The arrangement is such that the parts 16, 13, combine to form the auxiliary piston at the end of the cylinder in such a way as to provide a hydraulic stop in advance of the main piston 12 so that stresses from the action of the hydraulic stop are not imposed on the main piston 12, or on its attachment to the piston rod 11. As shown, large-bore passages 16a are formed in the part 17. During the main part of the stroke of the piston rod 11, liquid can thus flow freely from one side of the part 16 to the other. When the latter engages the part 13 the passages 16a are closed by the part 13 and liquid is trapped in the end of the cylinder. The passages 16a may alternatively be formed in the member 13. Packing 16b may be dispensed with, so as to provide a shock absorber action due to flow around the periphery of the part 16. Some passages (not shown) may be provided in either of the parts 16, 13, which are not closed when these parts come into engagement.

Abstract: 737,647. Rolling. SANDVIKENS JERNVERKS AKTIEBOLAG. Nov. 30,1953 [Nov. 29, 1952], No. 33245/53. Class 83 (4). Regulating means for a rolling mill comprises hydraulic or pneumatic jacks or pressureboxes 22, Fig. 1, under the screw-downs 25 and supplied with pressure medium, the outlets being connected to adjustable outlet valves 21 through which the flow is controlled by the relative movement between the rolls. Each valve 21 may be controlled by a lever 18 mounted on a fulcrum 19 attached to the upper roll bearing 11 and tilted by the relative movement of a pushrod 15 connected to the lower roll bearing 12. The position of the fulcrum 19 is adjustable by means of a screw 20 and the length of the rod 15 adjustable by a threaded sleeve 17. The rod 15 is preferably made of a material having the same coefficient of expansion as the material of the rolls and may be a tube supplied with a heating medium &c. to compensate for temperature effects. In operation, as the distance between the rolls increases, the rod 15 is lowered relatively to the lever 18 and the valve 21 is thereby throttled, causing an increase in pressure on the pressure-box 22 which reduces the distance between the rolls. In a modification the outlets from pressure-boxes under the screw downs of a rolling mill having cambered rolls is controlled by levers in sliding or rolling engagement with points on the rolls opposite the area of contact with the work. In both examples the levers may actuate pass-indicating devices and a servo device may be incorporated to obtain an advantageous speed/time curve and prevent " hunting." Specification 665,437 is referred to.
