Filed: 1927-12-21
Abstract: 295,889. Baranowski, K. Dec. 21, 1927. Ornamenting.-Ornamental effects are produced on metallic surfaces by pickling the article, placing in an electrolytic bath to produce a granular surface, and subjecting the article to the action of a flame directly on removal from the bath or after coating with solutions such as caustic soda solution, or with pastes made from suitable salts, such as silver nitrate. A protective coat of enamel or varnish may finally be applied. The bath may be of iron, brass, silver, or copper, and preferably consists of copper su1phate solution of 24‹ Be, the voltage applied being one or two volts or may be increased to ten volts. The article is preferably given a preliminary coating of copper and, where inlaid effects are required, a design is applied in a varnish which will resist the action of the bath, and is subsequent1y removed.

Abstract: 905,653. Sleeve couplings. GENERAL ELECTRIC CO. Ltd. Oct. 11, 1960 [Oct. 13, 1959], No. 34667/59. Class 38 (1). The two strip terminals 2, 3 of a sleeve coupling are separated by an insulating strip 4 from which they are slightly sprung away. The cross-section of this assembly is substantially square so that a coiled conducting spring 9 may be pushed over the assembly to make electrical connection between the terminals. The spring is housed within a helical groove 17 in a sleeve 10 of resilient insulating material, relative rotation of the spring and sleeve being prevented by engagement of the end portion 14 of the spring- and slot 16 in the sleeve. The strip terminals and their spacer 4 have their bases embedded in a block 8 of synthetic resin, the ends of the terminals being longer than that of the spacer to facilitate connection to electrical components (not shown) also embedded in the resin block. Specification 905,654 is referred to.

Title: Improvements in devices for determining position by means of the transit time of radiated waves
IPC: G01S13/84
Filed: 1956-11-14
Abstract: 811,762. Radiant-wave distance measuring systems. SOUTH AFRICAN COUNCIL FOR SCIENTIFIC & INDUSTRIAL RESEARCH. Nov. 14, 1956 [Nov. 15, 1955; Feb. 15, 1956], No. 34846/56. Class 40 (7). Relates to a radiant-wave system for determining at a first point AP the distance therefrom of a second point B in which first and second independent measuring frequencies fp and fb are transmitted respectively from the first and second points and are heterodyned at the first and second points to give identical second and first comparison frequencies (fpfb), the first comparison frequency being transmitted to the first point and there compared in phase with the second comparison frequency. According to the present invention the measuring frequencies are transmitted by modulation of respective first and second carriers of different frequency fc and fc1, the comparision frequencies are derived by heterodyning the modulated carriers and the first comparison frequency is also modulated on to the second carrier; the modulation may be phase, frequency or amplitude (including single sideband). As shown, the signal fp from a generator 10 is frequency modulated at 11 on to the carrier fc which is radiated by a transmitter 12 to a receiver 25 at the second point B when it is heterodyned in a detector 26 with the carrier fc1 which has been frequency modulated at 22 with the signal fb from a generator 21. The output from detector 26 comprises an I.F. carrier (fc1-fc) amplitude modulated by the first comparison frequency (fp-fb) which is selected by a filter 62 and detected at 63 giving a sinusoidal signal (fp-fb) which is converted to a corresponding pulse train in a generator 64 and applied to frequency modulate the carrier fc1 at 22. The carrier fc1 is thus frequency modulated by a sinusoidal signal fb and by a pulse companion signal (fp-fb) and this carrier is radiated from a transmitter 23 to a receiver 31 at the first point AP and heterodyned in a detector 33 with the frequency modulated carrier fc from the modulator 11, giving an I.F. carrier (fc1-fc) which is amplitude modulated by the sinusoidal second comparison signal (fp-fb) and frequencymodulated by the pulse first comparison signal (fp-fb). The second comparison signal is extracted by an amplitude detector 72 and produces a circular time-base on a C.R.T. 40 which is intensity or deflection modulated by the first comparison pulse signal which is extracted by a frequency discriminator 74. Alternatively the first comparison signal applied to frequency modulate the carrier fc1 may be in the form of a sinusoidal signal obtained directly from the detector 63. Suitable values for fp, fb, fc and fc1 are 10 Mc/s, 9.999 Mc/s, 3,000 Mc/s and 3,033 Mc/s. Specification 671,661 is referred to.

[Class 106 (iv).] In an electric liquid level indicator comprising a rheostat 17, the resistance per unit length of which increases towards one end, and over which a wiper arm 18 moves, the arm reaches the high resistance end and then passes off and breaks circuit when the liquid level falls below a certain minimum. The cross coil indicating instrument 12, 13 is furnished with means such as a stop pin 22 arresting the movement of the pointer 11, when left under the influence of coil 12 alone, at a zero scale indication, which is placed at an angular distance from the minimum current reading in accordance with the spacing of the remaining part of the scale. The rheostat consists of a tapered insulating strip 23 on which a coil 24 is wound from the narrower part to the wider. The object of the invention is to avoid the difficulties and disadvantages of constructing a resistance increasing sufficiently at low-level end of the scale to make it sufficiently open, by suppressing the lowest portion. The wiper arm 18 is attached to a spindle 35 rotated by bevel gear from an arm carrying a float in the tank. Specification 345,286, [Group XXXVIII], is referred to.

Abstract: 367,058. Machines for making stranded cables. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, London, and ROSEN, A., 100, St. Helens Road, Westcliff-on-Sea. Nov. 24, 1930, No. 35317. [Class 109.] I n order to secure constant tension in wires drawn from bobbins to form a stranded cable, a constant braking torque is applied to the bobbins, the torque being made to vary with the radius of turn of the strands leaving the bobbins. In the embodiment a bobbin comprising flanges 5, drum 5a and friction disc 6, is mounted on a spindle 5 freely carried in a U-frame 1. A bracket 2 on one limb of the frame 1 forms a bearing for spindles 9, 10 which have rigidly secured to them respectively, gear wheels 19, 17. An arm 7 is secured to the spindle 9,. and at its free end carries a roller 8 which rests on the outer layer of the turns of wire on the bobbin drum 5a. An arm 11 fitted to the spindle 10 ends in a cross-piece to which are pivoted lever arms 12, 12a carrying brake shoes 14, 14a respectively. The shoes 14, 14a are pressed into contact with the disc 6 by a spring 16 compressed between the arms 12; 12a. In operation, as the arm 7 is moved against the control of a light spring 9a on the spindle 9, the brake shoes 14, 14a are moved proportionally so that the point of application of the braking torque is moved on the friction disc. In a modified construction one brake shoe only may be provided, the spring 16 being compressed between the brake shoe arm and the lever 11. The brake shoe may bear on a flange of the bobbin; thus dispensing with a friction disc.
