Abstract: 912,540. Resistance measuring; instrument casings. NEWPORT INSTRUMENTS (SCIENTIFIC & MOBILE) Ltd. Feb. 9, 1959 [Feb. 17, 1958], No. 5099/58. Class 37. In an instrument for measuring high and low resistance values, the test potential for the high resistance range is obtained by rectifying the high voltage alternating output of a transistor oscillator 27, 28, Fig. 5, which is energized by a low-voltage D.C. source 15, which source also serves directly as a test potential source for at least one low resistance range. The resistance to be measured is connected across the common terminal 10 and the appropriate terminal 11-14. For the highest range, e.g. up to 200 megohms, terminals 10, 14 are used and the high potential built up across capacitor 37 by rectifying the output of the oscillator at 34, 35, is applied across the unknown resistance, the value of which is read off meter 18. The test potentials for two lower ranges, e.g. 2 megohms, 20 kilohms, are derived from potential divider 20, 21 and resistors 25, respectively, and are applied to terminals 13, 12. Switch 17 is left open, as shown, for the above measurements, but for very low resistances, it is closed and the unknown resistance is connected between terminals 10, 11. Variable resistor 23 serves for zero adjustment. The casing of the instrument is divided into three compartments, two of which are covered by plate 53, Fig. 3, of a transparent material which permits viewing of meter 18, the compartments being hermetically sealed by a flexible gasket 55. Push-button 24 is covered by gasket 55 and is operable through an aperture 59. The more durable circuit components are potted in an insulating resin 62. The knobs, switches and terminals of the instrument are mounted on the cover-plate of the remaining compartment so as not to project beyond plate 53.

Filed: 1941-04-22
Abstract: 547,174. Emergency stop-valves. COCKBURNS, Ltd., RODGER, J., and GRANT, T. April 22, 1941, No. 5176. [Class 135] A self-closing emergency stop valve normally opened and closed under hand control but adapted to close automatically in the event of reversal of flow or pressure drop at the inlet has a lift valve member 2 adapted to open in the direction of flow and coupled to a piston working in a cylinder connected to the inlet 1a through a non-return valve 10 and an auxiliary valve 8 adapted to be held open when the main valve handwheel is operated in the direction to permit opening movement of the main valve. The auxiliary valve spindle 18 is coupled to a hand lever 22 loaded by a spring 191 and having a toe 20 adapted to be engaged by a flange 21 on a screwed sleeve 11 working in a bridge supported from the valve cover 13 by pillars 16. The sleeve 11 encircles a reduced part 3a of the main valve spindle to co-operate with a shoulder thereon. When opening the valve the hand lever 22 may be first operated to admit inlet pressure to the cylinder and so counterbalance part of the unbalanced pressure on the valve member or the handwheel may be operated at once in which case the flange 21 coacts with the lever 18 to open the auxiliary valve. When the auxiliary valve is open fluid from the inlet passes to the cylinder where it acts on the piston to prevent sudden opening of the main valve. As fluid leaks past the piston to an exhaust chamber on the other side the main valve slowly opens. Should the inlet pressure fail the non-return valve 10 prevents the return of fluid to the inlet and the expansion of the fluid trapped in the cylinder closes the main valve, fluid on the other side of the piston leaking away through the clearance between the spindle and its guide. The exhaust chamber is connected to drain through a manually actuated valve 23. By opening this valve an emergency power operated valve closing action is secured.

Title: A method of automatically ascertaining the average weight of cigarettes delivered from a cigarette making machine
IPC: A24C5/34
Filed: 1948-02-21
Abstract: 651,981. Endless-belt conveyers. SKODA WORKS, NATIONAL CORPORATION. Feb. 21, 1948, No. 5188. Convention date, Feb. 21, 1947. [Class 78 (i)] [Also in Groups VI and XVIII] A machine for manufacturing cigarettes, of the kind having means for checking and regulating their weight, has a sampling mechanism which removes single cigarettes from a conveyer at timed intervals by seizing them by their ends and delivers them to a scale pan where they are weighed singly or in bulk, and then returns them from the pan on to the conveyer, the exchange of a cigarette or group of cigarettes on the scale pan being performed by two carriers provided with rests for one cigarette or a group of cigarettes and moving simultaneously in a mutually bound manner so that the cigarettes are at rest with respect to their supports during these movements. A square-section shaft 10, Fig. 1, which is rotated at a fixed speed has a slot 19 in which is pivoted a weight 20 arranged to swing from the full to the dotted position on rotation of the shaft through a half-revolution. Slidablymounted on this shaft are a pair of jaws 16, 17 which are operatively connected, by links 22, 23 with the weight 20 in such a manner that on continuous rotation of the shaft they intermittently close on a cigarette 2, transfer it from a belt conveyer 3 onto a rest 29 on an arm 28 and release it thereon. The arm 28, another rest arm 45, a scale pan 51 and a fixed bridge member 59 are arranged in comb relationship with one another, Figs. 4 and 5, and the arm 45 is arranged so that when pivoted its rest 46 follows the same path as that followed by the pan 51 during weighing movement, said arms 28, 45 being pivoted respectively by engagement of followers 41, 49 with cams 35, 36 rotated by shaft 10. Assuming cigarettes to be positioned on the rest 29 and scale pan 51, and the weighing operation to be completed, first the rest 46 lifts the cigarette from the pan to a position just above the position of the empty pan 51 as limited by stop 57. Rest 29 now swings over rest 46 and first its front portion 30 pushes the weighed cigarette from rest 46 to rest 47, after which the cigarette on rest 29 is transferred to rest 46. Arm 28 then swings to the right and arm 45 swings down, transferring the cigarette on rest 46 to the pan 51 in such a manner that the weight is not taken fully by the pan at first. Subsequent lowering of this arm leaves the cigarette on the pan 51 after which the cigarette on rest 47 is engaged by the bridge-piece 59 which returns it to the conveyer. In a modification, the scale pan is constructed to accommodate a plurality of singly selected cigarettes. In further modifications the weight 20 is replaced by springs or electromagnets and the arms 28 and 45 are operated by means other than cams 35, 36.

Abstract: 307,343. I. G. Farbenindustrie Akt.- Ges. March 5, 1928, [Convention date]. Benzoic acid.-Benzoic acid prepared catalytically from phthalic acid or phthalic anhydride, or from naphthalene by way of phthalic anhydride, is purified by treating it with reducing agents in the presence of water, whereby the naphthoquinone impurities are reduced to naphthohydroquinones while the phthalic anhydride, if present, is hyarated; the product is then leached with water to remove the naphthohydroquinones and the phthalic acid. According to the example, crude, finely ground benzoic acid pasted with water is treated with sodium bisulphite at 40- 50‹ C., and after 3 to 4 hours the mass is acidified with hydrochloric acid, cooled, filtered, and washed with water; substantially pure benzoic acid is obtained. Sulphur dioxide may he used instead of sodium bisulphite. The Specification as open to inspection under Sect. 91 (3) (a) states that the hydration of the phthalic anhydride may take place prior or subsequently to the reduction of the naphthoquinones. It states also that the product may be leached with aqueous solutions. This subject-matter does not appear in the Specification as accepted.
