Abstract: 886,752. Change-speed belt gears. TELEFUNKEN G.m.b.H. March 24, 1958 [March 25, 1957], No. 9284/58. Class 80 (2). [Also in Group XXXVIII] A two-speed gear for driving the capstan 11 of magnetic tape transducing apparatus comprises change-pulleys 4, 6a, 6b, arranged within an endless belt 8 or 9 and positionally interchangeable for ratio shift. In Fig. 1 a driving motor 2 carries both pulleys 4, 6a, 6b, the pulley 4 being fast on a motor shaft 3. As shown, the pulley 4 directly drives a driven pulley 10 through the belt 9 and the pulley 6a, 6b idles. By a half-turn of the motor 2 about an axis 5, the pulleys 4, 6a, 6b, exchange positions, the motor pulley 4 driving the pulley-step 6b at half speed through the belt 8 whilst the step 6a drives the driven pulley through the belt 9, giving a 2 to 1 ratio shift. Fig. 4 uses positionally interchangeable stepped and plain change-pulleys 20, 21 and an endless belt 22 driving a final capstan pulley 23, but the drive now enters via a second endless belt 13 passing over a motor pulley 12 and various idlers and engaging externally the pulley 21 or 20. When a frame 19 carrying the change-pulleys is given a half-turn from the position shown, the pulleys 20, 21 exchange positions and the single diameter pulley 21 engages both belts 13, 22, the output speed being thereby doubled. A jockey 25 tensions the belt 13 and the belt 22 may be elastic and/or tensioned by a jockey, not shown. By swinging a frame 18, carrying the frame 19 and the idlers, one way or the other, idler pulleys 15, 17 can be engaged frictionally with take-up spools 29 or 30 for driving the tape rapidly in either direction. A belt, not shown, normally drives the take-up spool 30 at slow speed from the capstan shaft 24.

Title: Improvements in spring roller blinds or screens
IPC: B60J1/20
Filed: 1928-03-27
Abstract: 311,880. Wilson, E. L., and Cotterell, L. E. March 27, 1928. Anti-dazzle screens.-In an anti-dazzle screen for the use of vehicle drivers of the type comprising a flexible. blind of tinted material adapted to be wound upon or unwound from a spring roller, the free edge of the blind is connected to a lazy-tongs or similar mechanism adapted to multiply a small initial movement of the operating device. In the construction shown in Figs. 2 and 3, the primary links 12 of a lazy-tongs are pivoted at 13 to a casing 3 housing the spring roller 5 for the blind 2, while the. final links 12<1> are pivoted at 23 to a rod at the free edge of the blind. Movement of the primary links 12 is effected by a slide 16, which is guided by the casing 3 and fitted with pins 15 engaging slots 14 in the links 12, while the slide 16 itself is actuated by the engagement of a pin 20, Fig. 7, on an operating lever 19 with a slot 21, Fig. 6, on the slide. The slots 14 are so shaped that, when the pins 15 reach the ends thereof during the extending movement of the blind, the lazytongs is automatically looked in its extended condition and cannot be released by pressure on the lazytongs. When the screen is to be returned to its casing, the slide 16 is given an initial movement in a reverse direction so as to remove the pins 15 from the ends of the cam slots 14, after which the blind and lazytongs are collapsed under the influence of the roller spring 6. In a modification the movement of the primary links is effected by pivoted levers connected to a slide actuated by a pivoted operating-lever, the end of which is looked in its extreme position, i.e. with the blind fully extended, by a spring detent. In another modification, the ends of a rod at the free edge of the blind are connected to a pair of lazytongs movable in guides and actuated by slotted levers mounted on a common operating spindle.

Title: Improvements in and relating to electric suction cleaners
IPC: A47L5/34
Filed: 1943-06-10
Abstract: 564,459. Vacuum cleaners. GENERAL ELECTRIC CO., Ltd., and JACOBY, H. C. E. June 10, 1943, No. 9347. [Class 8 (i)] In an electric vacuum cleaner having a revolving brush, the distance between the brush and the surface being cleaned is adjusted automatically in accordance with the tangential force between the two ; the regulation may also take account of the suction at the nozzle opening and may be varied to suit the nature of the surface. Fig. 1 shows apparatus in which the brush axle is suspended from links 9 pivotally mounted within chambers at the ends of the nozzle, one of which is biassed by an adjustable spring 14 ; the axle carries a friction wheel 16 arranged between friction wheels 17, 18 which can rotate a shaft 25 in opposite directions through skew gears, this shaft in turn adjusting a link 30, fixed to a transverse. shaft 31 supporting the front wheels through arms 32. Variation of the tangential force on the brush brings the wheel 16 into contact with one or other of the wheels 17, 18 and so raises or lowers the front wheels and alters the brush height from the surface. In another form, the biassed link 9 is caused to make electric contacts and so start in one or other direction an electric motor which raises or lowers the rear wheels through gearing. Fig. 13 shows a cleaner in which the movement of the link 9 actuates a valve controlling connection of the suction mouth through a pipe with bellows 51 acting on the rear wheels. The link may also be acted on by the suction applied through a diaphragm 71. The bellows may, alternatively, be subjected to inflow of air compressed by a fan, under control of a valve actuated by the link; or the bellows may be enclosed and subjected to pressure and suction on opposite sides. An adjustable bellows leakage and a filter for air entering the bellows may be provided. The link 9 may be adjustably mounted on its pivot, thus regulating the projection of the bristles and the intake area of the nozzle.

Abstract: 1,041,871. Hydrostatic gear control. M HERTER. March 11, 1963 [March 12, 1962], No. 9481/63. Heading F2D. In a vehicle hydrostatic transmission comprising an I.C. engine-driven pump 3, with displacement control 27, feeding a fixed-displacement reversible motor 4, pump displacement is controlled automatically and manually by a differential piston 25, subject on its smaller left face to pump pressure 5 and on its larger right face to a control pressure 30 derived from the main pump pressure 5 through an adjustable restrictor 21 and regulated independently by a reducing valve 33 loaded by a pedal 32, constituting the vehicle accelerator pedal, and by a paralleled reducing valve 31 loaded by a cam 35 actuated by the pump displacement control 27. The same control pressure 30 also acts on a piston 24 controlling the throttle or injection pump 22 of the driving engine. The pump displacement control 27 is thus responsive to load torque, as sensed by pump pressure 5, and the cam 35 also limits pump pressure to prevent engine overload, the cam profile being matched to the acceleration characteristic of the engine. The motor 4 is reversed by a fluid-pressure operated slide-valve 8 controlled by a manual valve 11. Also provided are a non-return valve 14 paralleled with the control-pressure restrictor 21, filters 15, 19 and an excess pressure reliefvalve 16.

A method of resistance butt welding the links of a chain comprises determining by experiment the quantity of electrical energy to be delivered to a link and during production taking a measure - ment of electrical energy supplied to each link up to that time and switching off the welding current upon delivery of the predetermined quantity of energy. The phase angles and numbers of current cycles subsequently fed may be altered, to ensure that the predetermined total amount of electrical energy is supplied. The current is passed through a reading device comprising a number, e.g. a hundred, adjustable resistance/capacitor combinations contacted by carbon brush devices, the device actuating a phase shifting circuit for ignitions controlling the current. The energy supplied at each of several instants of time is measured and deducted from the predetermined quantity and the current supply is ceased when the predetermined quantity has been delivered.

IPC: C12N9/02
Filed: 1985-08-26
Abstract: Peptidyl-glycine  alpha -amidating monooxygenase is an enzyme extractable from medullary thyroid carcinoma cell lines and tissue samples, having a molecular mass of about 60,000 to 65,000 daltons. It has been purified so as to exhibit a single, homogeneous, well-defined band using electrophoretic procedures performed on SDS-polyacrylamide gels, and has a specific enzymatic activity of at least 50 mU per mg protein. The free or immobilized enzyme, in the presence of Cu+2 ions, ascorbate, and oxygen, can be used to prepare an  alpha -amidated protein from a polypeptide substrate possessing a carboxyl-terminal glycine residue. The purified enzyme can be used as an antigen in order to produce enzyme-specific monoclonal antibodies, and can provide the information necessary to design and construct prokaryotes or other appropriate unicellular organisms or host cells isolated from multicellular organisms which possess peptidyl-glycine alpha -amidating capability.
