Title: Improvements relating to the modification of colours in glasses
IPC: C03C1/10
Filed: 1922-02-07
Abstract: 192,919. Haddan, R., (Corning Glass Works). Feb. 7, 1922. Production of metal.-A process for modifying the colours due to metallic salts in glasses, particularly the borate glasses coloured by cobalt oxide or nickel oxide, consists in adding a substance or substances containing one or more of the halogens, such as chlorine. As an example of the change, it is stated that when potassium chloride is added to the batch of glass containing a very high proportion of boric oxide and coloured with cobalt oxide, the resultant glass has a green colour instead of red. The colour change is less noticeable when the proportion of boric oxide in the glass is low or when other halide salts are used instead of the chloride.

Abstract: 393,027. Weighing-apparatus; dynamometers; tension-measuring machines &c. CHATILLON & SONS, J., 85, Cliff Street, New York, U.S.A.-(Assignees of Wasson, R. B. ; 12, Riverview Apartments, Riverside Drive. Cranford, New Jersey, Forest, A. V. de ; Southport, Connecticut, and Sayre, M. F. ; 1169, Parkwood Boulevard, Schenectady, New York, all in U.S.A.) Feb. 6, 1932, No. 3612. Convention date, Feb. 14, 1931. [Class 143.] A force-measuring machine, for example a weighing-scale, dynamometer, or tensionmeasuring machine, comprises a resisting system including two metallic springs each deviating differently from desired behaviour due to one characteristic of the springs such as creep, hysteresis, change of modulus of elasticity with temperature change, or non-uniform rate of deflection with respect to load, and differential means such as a differential lever or its equivalent, to which each of the springs is connected, the ratio between the magnitude of the deviation of the springs being equal to the ratio between the distances from the points of attachment of the springs to a motion transmission point of the differential means, whereby the differential means is adapted to compensate for the deviation of the individual springs. As shown in the Figure 2, three weighing springs 12, 14, 15 suspended from the frame 2 are connected to a load-supporting bar 8, an intermediate differential lever 22 being used to actuate the indicator spindle 29. The springs 14, 15 are of composite type connected by screw adjustors or calibrators 21. For example, the spring 14 may comprise upper and lower springs 17, 18, of Invar and Monel metal respectively, whilst the spring 15 comprises upper and lower springs 19, 20 of steel and Monel metal. By making the springs of suitable sizes and cross-sections and taking advantage of the different physical properties of the materials of the springs adjustments may be made by means of the screw adjustors 16, 21, to compensate for the individual deviation of each of the springs due to temperature change, permanent set, creep, hysteresis, or acyclic behaviour. In a modification, the ends of the springs 14, 15 may be adjusted laterally along the frame 2 and differential lever 22.

Title: Improvements in razors
IPC: B26B21/32
Filed: 1955-02-08
Abstract: 821,826. Razors. WILKINSON SWORD Ltd., and RANDOLPH, H. B. May 8, 1956 [Feb. 8, 1955], No. 3698/55. Class 30 The invention relates to a safety razor in which the blade clamping means has two blade receiving positions, one so as to fully clamp a blade for shaving, whilst the other is a positively located position in which the blade is held less firmly for rinsing. In the preferred embodiment the razor head is in one piece and comprises and a split cover, the two portions 11a, 11p of which have tongues 11a2, 11b2 hinged to yokes 17a secured to a crossbar 17. Connected to the crossbar and extending through the razor handle is a push rod- 15; recessed at the lower end to form an a guard 10 on which the blade 12 seats, abutment surface 15a. About the end of the rod is a rotatable screw threaded sleeve 16 secured to an external cap 13 by which the sleeve is screwed into the handle. When the sleeve is unscrewed to its full extent the blade is clamped against the guard 10. On screwing the sleeve into the handle, spacing between the end of the sleeve and surface 15a allows the push rod to project below the cap. Continued screwing causes the slide rod to move upwards until a spring urged pawl 18 on the rod engages a detent 14c in the handle, when the blade cover is spaced from the guard for rinsing the blade (Fig. .5). To open the covers 11a, 11b, the rod 15 is pushed until the pawl 18 enters a second detent 14c when the tongues 11a2, 11b2, will have contacted the lower edge of the guard 10 and thus have caused the covers 11a, 11b to pivot about the yokes 17a freeing the blade. The covers have a concave outer surface 11b1. Horizontal channels 10a are cut in the guard 10, tapered so as to give a venturi action and to direct water during rinsing against the cutting edges of the blade. A trade mark is impressed on the cover to distinguish the two sides of the razor.

IPC: C22F1/02
Filed: 1956-02-07
Abstract: 788,422. Bright annealing. FRITZ, C. Feb. 7, 1956. No. 3795/56. Class 72 [Also in Group XXIX] Metals are bright annealed in a closed container which is pushed upwardly into an annealing furnace, a high vacuum, being produced in the container during annealing and a protective gas introduced into the container after annealing to accelerate cooling. As shown a container B connected through a valve J to a vacuum pump C is inserted upwardly, by means of a mechanical or hydraulic lift G, into a downwardly opening electrically heated furnace F. The container, and, if required, the furnace is then evacuated and the material annealed. When annealing is complete the container is returned to atmospheric pressure and a current of protective gas, e.g. nitrogen from a cylinder or generator, passed through it. A current of gas may also be passed through the furnace to assist in cooling. The evacuation of the container may be repeated during annealing. A valve incorporating a safety blow-off device may be included in the pipe line between the container and the pump.

Title: Improvements in or relating to the recovery of thermo-plastic resins from solutions thereof
IPC: C08F6/12
Filed: 1944-03-07
Abstract: <PICT:0598354/III/1> Thermo-plastic resins are recovered from solutions by feeding the solution into the top of a stripping column maintained internally at a temperature greater than the softening point of the solvent-free resin and at a pressure equal to or greater than atmospheric pressure, introducing live steam into the column near the base, and withdrawing the resin, in the molten state and substantially solvent-free, from the base of the column through a seal.  The resin may then be solidified as a film on a cooled rotating cylinder and finally scraped off in the form of flakes. The process is particularly applicable to solutions of indene and of coumarone resins in solvent naphtha.  Resin solution is passed through pre-heater 6 and fed into the pre-stripping sections 25 of bubble-cap column 7 where it is further heated by effluent vapours from the lower sections.  These lower sections, to which the p solution now passes, are heated by steam-coils 13.  Live steam enters the column through pipe 26 and strips the solvent from the resin. The latter collects on plate 27, overflows through pipe 28 which dips below a heated layer of resin in the base of the column, and is eventually withdrawn through the steam-jacketed conduit controlled by valve 30.

Abstract: 470,408. Minimizing inductive disturbance. BLUMLEIN, A. D. Feb. 13, 1936, No. 4420. [Class 40 (iv)] Electrical interference at relatively low frequencies, e.g. up to 1000 #. in a cable of the coaxial conductor type is reduced by making the input impedance feeding the cable high at such frequencies compared with the surge impedance of the cable. The terminating impedance at the receiving end may be of the same order as the surge impedance, preferably, the surge impedance at a high frequency. The cable length, say 10 miles, is electrically short, e.g. less than #th wavelength at the frequencies in question, but if the cable length .is shorter, say 1 mile, interference up to 10,000 #. is reduced. The outer conductor shields the cable at higher frequencies, the shielding action being increased if necessary by iron taping. The input impedance may, as shown, be a highimpedance tetrode (or pentode), having the anode connected by a large condenser P to the central conductor C and the cathode connected to the outer conductor S. Potential is fed to the anode over a high resistance LR, the input impedance being about 8000 ohms. and the terminating (surge) impedance R, 80 ohms. Interfering currents pass over the terminating and input impedances in series so that the voltage drop over R is negligible.
