Title: Improvements in electric starter apparatus for internal combustion engines
IPC: F02N15/06
Filed: 1956-11-15
Abstract: 801,911. Engine turning gear. GENERAL MOTORS CORPORATION. Nov. 15, 1956 [Nov. 18, 1955], No. 34931/56. Class 7(5) In an electric starter apparatus in which the pinion is moved axially by one end of a pivoted lever the other end of which is connected to the armature of an electromagnet mounted adjacent the starter motor a single end housing member is secured to the field frame of the motor and formed with recesses so as to enclose the pinion and lever and close one end of both the motor and the electromagnet. As shown, end plates 14, 16 are secured at opposite ends of the field frame by bolts 18. The pinion 34 is driven from the motor shaft by means of an over-running clutch 36. The driven member may be either inside or outside of the clutch. Helical splines 40 are engaged by corresponding splines on the interior surface of a sleeve 38 and there is some rotation of the sleeve, clutch and pinion during axial movement toward the engine gear 32. Windings 72 and 74 are energized to effect movement of the pinion into mesh and also to close the starter motor switch (not shown). One of the windings is rendered ineffective when the switch is closed. De-energization of the electromagnet may be controlled-manually or automatically by engine suction or by the action of the generator. When the collar is moved to the left it engages a snap ring (not shown). The spring 60 is compressed and exerts a pressure on the armature 20 and moves it with the shaft 22 to the left. The washer 106 is engaged by a surface on the armature and the end plate 14 and acts as a brake to stop the motor. The enlarged head 98 of the link 100 has a flat surface 104 spaced from the end of the armature 76 and there is also some lost motion between the lever 42 and the pivot pin 102. The pivot pin 44 has an eccentric portion so that by rotating the pin the position of the lever 42 can be accurately adjusted from outside the housing.

Patent GB-975949-A (GB)
Title: Recovery of cyclohexanone
IPC: C07C45/78
Filed: 1960-12-14
Abstract: Substantially pure cyclohexanone is recovered from a mixture consisting predominantly of cyclohexanone and cyclohexanol and substantially free of higher boiling constituents and cyclohexane by separating from the product mixture by fractional distillation under subatmospheric pressure a fraction enriched in cyclohexanone and subsequently separating from the said fraction substantially pure cyclohexanone in a second fractional distillation at a higher pressure, which is not higher than atmospheric pressure.  Prior to the first fractionation above, higher boiling constituents are removed by fractional distillation under sub-atmospheric pressure of the starting material.  The first two fractionations are preferably at substantially the same pressure and the final distillation of cyclohexanone at a pressure higher than that of both preceding distillations.  In an example, an oil feed obtained from the oxidation of cyclohexane and augmented by the products of dehydrogenation of a cyclohexanol fraction is distilled at 16 mm.Hg. to separate a cyclohexanone-cyclohexanol mixture from heavy ends, the product is scrubbed with sodium hydroxide solution, the oil phase is fractionated at 16 mm.Hg. and the overhead fraction is fractionated at 60 mm.Hg. to produce cyclohexanone of 99.4% purity. The dehydrogenation of the cyclohexanol fraction and recycling is described in Specification 975,948.  Specifications 909,227 and 966,546 also are referred to.

Title: Improvements in or relating to television, facsimile and like signal transmission systems
Inventor: CHERRY EDWARD COLIN
IPC: H04N3/00
Filed: 1956-11-20
Abstract: 858,346. Television. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 4, 1957 [Nov. 20, 1956], No. 35465/56. Class 40(3). [Also in Group XL(c)] In a television transmission system the maximum frequency transmitted is restricted to a pre-determined value by reducing the scanning velocity in proportion to the increase in average energy in the video signals which have frequencies in excess of the predetermined frequency. This arrangement allows a practical bandwidth compression of 4À7:1 in a television signal for which the maximum theoretical compression possible is 5:1. Fig. 1, shows the general arrangement in which a high-pass filter 3, the cut-off frequency of which is equal to the predetermined frequency, supplies signals above this frequency, derived from a television camera I, to a full-wave rectifier 4 the output from which is supplied to the time-base unit 5 which supplies scanning signals to camera 1 so as to control the velocity of scan inversely as the amplitude of such output. To avoid difficulties caused by the delay introduced by high-pass filter 3 the arrangement shown in Fig. 2 in which the high-pass filter is replaced by a low-pass filter 6 having the same cut-off frequency and a subtractor circuit 7 is preferably employed. For controlling a cooperating receiver the video signals available at terminal 2 and scanning control signals derived from time-base unit 5 are transmitted on separate channels including either cable or radio links. Circuit details of suitable arrangements for the high and low-pass filters, the subtractor circuit, the time base, sawtooth generator and associated scanning amplifier are given with reference to Figs. 5 to 9 (not shown).

Title: Improvements in and relating to electrostatic spray-coating methods and apparatus
IPC: B05B12/00
Filed: 1960-10-20
Abstract: A method of electrostatic spray painting an article by means of a paint atomizing and charging device comprises atomizing the paint into a spray and depositing the spray upon the article with the aid of an electrostatic field, the method including the steps of maintaining the article at substantially earth potential, establishing a high voltage electrostatic deposition field between the article and a charging electrode on said device at high potential and a high voltage electrostatic field between said charging electrode and a counter-electrode on said device, the charging electrode being effectively shaped, at that part nearest the article, as a point, thereby to produce in the immediate vicinity of the electrode zone of high ionization, directing into said zone the discharge from the adjacent discharge orifice of an orifice type mechanical atomizer, whereby finely atomized paint particles produced in or directed into said zone are charged and thereupon move under the influence of the field between said charging electrode and the article, procuring that substantially all the paint in the discharge traverses said zone, and maintaining the region between said zone and the article free of any element, including said counter-electrode, which would significantly diminish the intensity of ionization or the deposition effect of said field in said zone, the average potential gradient of the field between the charging electrode and the counter-electrode being greater than that of the field between the charging electrode and the article.  In a second embodiment, the average potential gradient between the charging electrode and the counter-electrode is greater than five kilovolts per inch. Apparatus is described comprising a mechanical paint atomizer, a charging electrode, and a counter-electrode arranged so as to produce a zone of ionization through which the discharge from the atomizer passes, the distance between the charging electrode and the counter-electrode being less than a distance between the charging electrode and the article to be painted at which, with a potential of not less than 20 kilovolts between the charging electrode and the article, the apparatus will effectively paint the article.  In a further embodiment of apparatus the average potential gradient between the charging electrode and the counter-electrode is said to be not less than 5 kilovolts per-inch or is greater than the average potential gradient between the charging electrode and the article.  The atomizing device may contain a resistor in the high voltage electrical circuit so as to limit the effective capacity of the electrode.  The atomization of the paint may be by means of compressed air, or by ejection under high pressure through a small orifice.  Additional air from a further orifice or orifices may be used to shape the spray.
