Title: Improvements in or relating to the coating of articles
Inventor: KNIGHT HOWARD RICHARD JAMES
IPC: B05B13/02
Filed: 1960-10-07
Abstract: 965,755. Coating apparatus. CARRIER ENGINEERING CO. Ltd. Sept. 29, 1961 [Oct. 7, 1960], No. 34519/60. Heading B2B. Apparatus for coating the horizontal surfaces 4 and 6 of articles connected in spaced relation to conveyer beam 2 by hangers 3 engaging the front and rear faces of the articles, comprises spray heads 7 and 55 mounted on arms 31 and 56 which are pivotally connected to carriages 29 and 57 which are reciprocated along cross beams 16 and 58 mounted on pillars 9 and 59 positioned outside the path of travel of the articles. The arm 56 is withdrawn to allow the hangers 3 to pass. The cross beam 16 may be moved up and down pillar 9. The articles may also be carried by floor conveyers and in this case the crossbeam 58 is movable up and down and arm 31' is withdrawn. The spray heads 7 and 55 are supplied with paint, atomizing air and control air. The respective control air pipes are connected to cam boxes 23 and 64 containing valves which are operated by cams to control the supply of air to the spray heads, the cams being selected manually or automatically in relation to the article size and synchronized with the movement of the articles. Means responsive to the presence of an article, e.g. photoelectric device 37, in connection with a timing device may be present to control the spraying period. A safety probe may be provided to stop the machine if the articles approach the spray heads too closely. The movement of the spray heads is interlocked with the movement of the articles. Electrostatic sprayheads may be used. A colour changeover device may be incorporated in the apparatus so that different coloured paints may be sprayed without dismantling and cleaning the gun. Specifications 965,753 and 965,754 are referred to.

Addition to 386,009. [Class 38 (iii).] In a system described in the parent Specification, the independent field winding d of the exciter E is supplied during regenerative braking and normal running, by the difference of a constant voltage U and a voltage u obtained from an exciter p driven by the vehicle. The braking torque of the motor M is thus dependent on speed, and the motor passes automatically from braking to motoring operation at a speed selected by adjusting the voltage U, or by varying the field of the exciter p. Specification 390,235 is referred to.

Abstract: 640,539. Internal-shoe drum brakes. BONNEBEAU, [nee DELARUE, M. T.] Dec. 30, 1947, No. 34728. Convention date, Oct. 22, 1946. [Class 103 (i)] In an internal - shoe , drum brake, two hydraulically or mechanically-operated similar shoes 10a, 10b are oppositely located and arranged to abut against fixed anchor points 18a, 18b. The shoes 10a, 10b are pivotally connected to two intermediate shoes 17a, 17b which have at their lower ends pins 20a and 20b engaging slots in two plates 21 having between them on a pin 22, a cam member 23, the lower end 23b of which is normally clear of the drum t. The leading shoe of shoes 10a and 10b on engagement with the drum acts through its abutment 18a or 18b to displace the adjacent shoe 17a or 17b in such a way as to move the cam 23 into contact with the drum. The cam 23 then pivots on its pin 22, as shown in Fig. 3, so as to spread apart the ends of shoes 17a and 17b. The second of the shoes 17a or 17b then forces the non-leading shoe 10a or 10b against the end stop on the actuator 15 so that an evenly distributed brake pressure is obtained and the braking effect is reflected back on to the actuator. The hydraulic actuator shown comprises two pistons p, the effort from which is transmitted through springs 13, the compression of which in caps 12 may be adjusted by the screws 14, and through adjustable stops 15 for setting the clearance of shoes 10a, and 10b.

Patent GB-608253-A (GB)
Title: Frequency measuring system
IPC: G01R23/00
Filed: 1945-12-31
Abstract: 608,253. Frequency measurements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 31, 1945, No. 35314. Convention date, April 20, 1944. [Class 37] A frequency to be measured is mixed with an adjustable frequency to produce either a zero frequency or a predetermined frequency, and the adjustable frequency is measured by counting its oscillations or the oscillations derived by beating with a standard oscillator in an accurately determined time interval, so that the unknown frequency can be calculated. The unknown frequency from 12, Fig. 1, is heterodyned with oscillations from 14 to produce zero beat frequency, and the oscillations from 14 are passed to a counter 20 over a " gate " 18 opened for a known time under the control of a standard frequency source 22. The heterodyning frequency may be an harmonic of the oscillator 14, and the oscillations to be counted may be the beat derived from oscillators 14 and 22, Fig. 3 (not shown). The heterodyning frequency may be derived from oscillator 22 by frequency multiplication or division followed by harmonic generation and selection, Figs. 2 and 4 (not shown). In a practical embodiment, standard oscillations of frequency 100 c/s are derived at 53, Fig. 5, from standard oscillator 22 and applied over transformers 55, 56 to produce pulses on grids of valves 58, 59 normally non-conducting. On closing key 71, valve 58 is enabled to pass pulses from 53 to multi-vibrator 66, 67 to render valve 66 non-conducting and valve 67 conducting, so that valves 59, 62 and 63 are enabled to conduct. Valve 62 thus passes oscillations of unknown frequency from source 12 to counter 65, valve 63 maintaining the current through resistance 110 constant. Valve 59 allows pulses to pass to a decimal counter 74 feeding a further decimal counter 75, so that after ninety pulses, condenser 76 is sufficiently charged to render valve 68 non- conducting and valve 69 conducting to allow 61 to become conducting. When the next pulse from counter 74 is applied to counter 7 (i.e. the total of pulses reaches one hundred), a pulse is passed over condenser 77 to valve 61 to cut-off valves 62 and 67 and restore the circuit. Counter 65 thus shows the number of oscillations from source 12 in one second. In a modification, Fig. 7 (not shown), a manuallyoperated switch renders valve 62 conducting simultaneously with a similar valve passing oscillations from a standard source to a counter; on releasing the switch, both valves become non-conducting simultaneously and the unknown frequency is. calculated in terms of the two counter readings and the standard frequency.

Abstract: Shark liver oil is vacuum distilled to give a residue which when hydrolysed by lipase of Ricinus seeds and further vacuum distilled yields a concentrate containing fatty acid esters of glycerol ethers. The latter may be saponified with KOH and the unsaponifiable fraction extracted with ether.  A product having a high (85% w/w) content of free glycerol ethers may be obtained from the fraction after removal of ether and vacuum steam-stripping of the residue.ALSO:An internally-administrable pharmaceutical preparation in dosage unit form comprises at least one glycerol ether of the formula CH2OH, CHOH, CH2OR wherein R is a C14-26 aliphatic hydrocarbon radical, or an ester thereof, together with a diluent or carrier.  Preferred glycerol ethers are those known as batyl, chimyl, and selachyl alcohols and glycerol a -monoaliphatic ethers wherein the radical R contains 16C atoms and one double bond.  The esters may be mono- or di-esters and are preferably derived from naturally occurring saturated or unsaturated fatty acids.  Such esters may be derived from various fish liver oils.  The preparations have a wide spectrum of physiological activity, including anti-infective properties, the ability to alleviate psychotic symptoms, and growth-stimulating activity, particularly of various kinds of blood cells.
