Abstract: 958,589. Rectifying. VARIAN ASSOCIATES. Dec. 22, 1960 [Dec. 23, 1959], No. 44168/60. Heading H2F. Apparatus for providing a high vacuum comprises a sputter-ion vacuum pump supplied from an A.C. source through a rectifying arrangement which includes a current limiting transformer. As shown, A.C. from a supply 11 is supplied through a switch 12 to the primary winding 14 of a current-limiting transformer 15 which is shunted by an indicating light 16. The transformer has a magnetic core with a shunt leg 20 which includes an air gap and provides the current limiting feature. A secondary winding 17 feeds a bridge of rectifying semi-conductor diodes 19 which are shunted by resistors 21 to equalize reverse voltages. The D.C. output is smoothed by capacitor 26 and the positive terminal is connected through coaxial cables to the loads which as shown are electrodes in the vacuum pump. In series with the load is a meter 34 protected by a diode 36 which has a characteristic approximately as shown in Fig. 6. A variable resistor 31 also shunts the diode to provide various ranges by moving a switch 32. In one position of the switch a voltmeter is provided. Specification 910,607 is referred to.

Title: Viscosity gauging device
Inventor: GERIN FERNAND LEON
IPC: G01N11/00
Filed: 1970-09-17
Abstract: 1,269,589. Measuring viscosity. F. L. GERIN. Sept. 17, 1970, No. 44479/70. Heading G1S. The present Specification relates to an improvement in the device described in Specification 985,494 for measuring the viscosity of a liquid particularly the crank case oil of an engine in situ. In that device engine oil under pressure passes through a pipe 5 into a lower part of the casing of the device where the pressure of the oil pushes two weighted pistons 10A and 11A into cylinders 10 and 11. The oil passes from the lower part of the casing to an upper part where it communicates through an orifice with cylinder 11. Cylinder 10 communicates through an orifice with a reservoir of unused oil. When pressure of oil introduced to the device is stopped, the pistons 10 and 11 fall at rates controlled by the viscosities of the unused and used oils respectively. If the viscosities are equal the pistons fall at similar rates and are arrested at the same height by a balance arm 15 journalled at 16 and magnetically coupled to pointer 17. If the used oil has a viscosity different to the unused oil the pistons are arrested by the balance arm 15 at different heights. According to the improvement of the present Specification, if the pistons are arrested at different heights, one of the pistons will contact a resilient wire 24 to activate a lamp 34 or auditory signal to show that the oils viscosity is not acceptable. Signals 30a and 31a may be provided to indicate whether the oil is too thick or too thin respectively. The device functions automatically when the engine stops or may be caused to function by closing valve 7 manually or by closing solenoid valve 40.

The lactams and ketones are used in the control of insects, possessing the ability to inhibit metamorphosis, act as a direct insecticide, particularly at the embryo stage, act as a sterilant or break the diapause of an insect. The lactams and lactones can be applied to the insect at any stage in its development, or to its potential habitat in the conventional formulations.

Abstract: 976,825. Phase shifting. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 25, 1963 [Dec. 3, 1962], No. 45639/62. Heading H2F. A phase shifting arrangement having one terminal common to the input (terminals T1 and T3) and the output (T2 and T3) comprises a bridge of three resistors and a reactor (R1, R2, VR and capacitor C3) which supplies a variable phase signal between the emitter and base of a transistor TR1 connected in such a manner that it has a high output impedance. The transistor is supplied from an independent D.C. source, and D.C. blocking capacitors C1, C2, C4 separate the D.C. and A.C. circuits. The A.C. impedance of capacitor C2 is so low that its effect on the bridge circuit is negligible. Either the resistor VR or the reactor C4 may be variable, and if the reactor is an inductor then a large D.C. blocking capacitor must be connected in series with it. The transistor is biased to its operating point by a potentiometer comprising resistors R4, R5, and as its impedance is high loading of the output does not affect the phase shift. Component values are given in the Specification.

A projection apparatus comprises two projection systems having a slide magazine therebetween, two deformable transverse passage elements on either side of the magazine coupling it with the projection gates of the projection systems, and a flexible tongue transversely displaceable within the passages to deliver slides to and from the magazine and projection gates and simultaneously controlling the opening and closing of total closure diaphragms forming part of each projector. As shown in Fig. 1, images from two pivoted projectors 10, 20 are brought into convergence by means of a threaded rod 31, and focused by threaded rods 15, 25. The flexible tongue 50 is moved to the left by a handle 51 and lugs on one end of its rear face move a slide from the rear compartment 33 of the magazine 30 through the deformable passage 40 to the projection gate 12. A wedge on the front of the tongue 50 passes a slide already in the gate and, on moving the tongue to the right, this slide is returned to the front compartment 34 of the magazine. While moving the tongue to the right, a slide has been moved from the magazine 30 to the other gate 22. The diaphragms 71, 72 are of two blades each carried on shafts 73, 75 and 74, 76 which carry cams 73a, (75a), and 74a, 76a rigidly fixed thereon. Above the cams are balance trays 61, 62 on the ends of a pivoted balance bar 60. On pressing a tray down on to the cams by means of the transverse position of a pin 52 on the handle 51, the diaphragm corresponding to that tray is opened. A diaphragm is opened after the projected slide has moved out of the corresponding gate, and the other is simultaneously closed before an unprojected slide is moved into the gate. The diaphragms may both be maintained open for panoramic projection and crossed polarizing filters placed over the lenses for stereoscopic projection.
