Abstract: 225,920. Johnston, J. Sept. 10, 1923. Variable-speed gearing is rendered automatic by the action of planetary unbalanced masses m each of which rotates in a plane parallel to the axis of the gearing with a cyclically varying speed. Fast on the driven shaft b is a casing c<1> carrying a diametral shaft i connected by a bevel gear pair i<1>, i<2> to a driving-shaft a. The masses m are preferably arranged in pairs to give radial and lateral balance upon diametral shafts l, l<1> which are geared together by equal pinions b<2>. The mass-carrying shafts are actuated with cyclically-varying speed by a set of three eccentric or elliptical toothed wheels, k, k<1>, k<2>, the middle wheel k<1> being loose and the outer ones fast on their shafts. The masses are moving fastest at the point where their centrifugal force tends to drive the casing c<1>.

Abstract: 726,297. Automatic frequency control systems. BENDIX AVIATION CORPORATION. Aug. 19, 1953 [Sept. 10, 1952], No. 22910/53. Class 38 (4). In an automatic frequency control system for a dynamo-electric inverter, a circuit responsive to output frequency, controlling a variable resistance in the field circuit, is influenced by anti-hunt negative feed-back means responsive only to transient changes of field excitation. As shown, a D.C. shunt motor 4 is supplied from a D.C. source 1 and drives a generator 13 producing an alternating voltage between conductors 19, 20. Deviations of generator frequency from a desired value are detected by a capacity-inductance circuit 43, 40, supplied through a transformer 36 from the generator terminals, which is resonant at a frequency slightly different from the desired frequency. The voltage across inductance 40, the phase of which changes with generator frequency, is applied to the grid-cathode circuit of a gas-filled valve 29 controlling the energization of the operating winding 24 of a carbon pile regulator 8 in series with motor field winding 6 so that frequency is automatically maintained constant by adjustment of speed. The resonant frequency of the capacity-inductance circuit is set by a rheostat 53 adjusting the energization of a saturating winding 48 of inductance 40. To prevent hunting, feed-back from the motor field through a condenser 59 is applied to a further saturating winding 47 of inductance 40. A voltage regulator (not shown) may control generator field 12.

Title: A new or improved window cleaning device
IPC: A47L1/03
Filed: 1933-08-18
Abstract: 404,392. Window-cleaning devices. DIXON, A., 7, Hannah Street, Elswick, Newcastle-on-Tyne. Aug. 18, 1933, No. 23162/32. Addition to 376,119. [Class 138 (i).] In a windowcleaning device such as described in the parent Specification, each wiper-holder is provided with front and rear pads and is pivotally mounted so that one or other of t he pads may be presented to the pane, reversal of the holder being effected b y rack and pinion means. As shown in Figs. 1 and 2, each wiper is in two parts, each part consisting of a holder 18 with clips 18a to retain the pads 19 in place. The holders are mounted on the ends of a rod 58 which is rotatable within a sleeve 61 pivotally connected by a screw 50 to the end of the wiper-carrying rod 17. A T-shaped spring 64 secured to the rod 17 has plugs 66 adapted to engage holes 62 in the sleeve 61 and notches in the rod 58. The rod is provided with toothed rings 59, each adapted to be engaged by a rack 70 on one end of a lever 71. The other end is connected to a vertical slidable rod 73, the lower end of which is pivotally connected to a bell-crank lever 75. One end of the lever is spring-pressed against the bracket 5. Normally the rack 70 is out of engagement with the toothed ring 59, but when the pads 19 require to be reversed, the upper part of the vertical arm 8 is pulled away from the pane 13, causing the lower part to move towards the bracket 5, whereby the lever 75 is rocked and, through the rod 73, brings the lever 71 into a horizontal position. On moving the wiper 18 upwardly the toothed ring 59 engages with the rack 70 so that the wiper is reversed, the spring-pressed plugs 66 being disengaged from the notches in the rod 58 and engaging other notches brought into position by the half revolution of the rod. The carrier member engaging the window sill is in two parts 1, 1a having interengaging stepped edges 1b secured together by removable pins 1c. The pads 19 are adapted to be reversed in a similar manner in the construction shown in Figs. 6, 7, and 8, wherein the vertical movements of the wiper devices are effected by screw and nut means. The brackets 5 are each provided with side cheeks 78 and a horizontal ledge 79 in which is mounted the spindle of the bevel wheel 42. The upper end of the spindle carries a member 80 in which is pivotally mounted a ball 81, the ball being also pivotally mounted in the jaws of a member 82 fixed to the lower end of the externally-threaded spindle 31. The vertical arm 8, which is pivotally connected at 6 to an extension of the bracket 5, is provided with an arcuate slot 84 in each side wall 7 for engagement by a stud 85 extending from a cheek 78 of bracket 5, The studs and slots limit the outward movement of the arm 8 about the pivots 6.

Abstract: 584,666. Vehicle lamps; lenses. SOC. POUR LA FABRICATION DES PROJECTEURS ELECTRIQUES MARCHAL. Aug. 12, 1939, No. 23315. Convention date, May 11. [Classes 75 (ii) and 75 (iv)] In a light projector for automobiles comprising a reflector and stepped refractor, the luminous beam passing through the central zone of the refractor has such an angle of divergence as to illuminate the whole of the required field and the beams passing through the peripheral zones illuminate only central zones within the field where a higher illumination is required. Fig. 10 shows a vehicle headlamp comprising an ellipsoidal reflector 6 haying a light source 7 arranged at its focus F and fitted with a refractor formed in several steps f1, f2, f3, f4, f5, all having their focus at the other focus F' of the reflector but of differing focal lengths, the beams passing through the various steps illuminating areas G1 H1 I1 J1, .... G5 H5 I5 J5 respectively on a distant screen. In another construction the reflector is of hyperbolic section. In a further construction the reflector consists of several surface elements of which some may be elliptical in section and others parabolic or hyperbolic. Fig. 15 shows a reflector composed of three ellipsoidal portions 61, 62, 63 having one focus at F and the others at F<1>1, F<1>2, F<1>3 respectively used in conjunction with a refractor composed of steps f1, f<1>1 having their focus at F<1>1, steps f2, f<1>2 having their focus at F<1>2, a step f3 having its focus at F<1>3, and steps f4, f5 of caustic form having foci between the foci F<1>1, F<1>2, F<1>3. The reflectors may be formed by the rotation of a parabolic are about a line parallel or slightly inclined to its axis. The arcs of the steps of the refractor may be so arranged that the illuminated areas instead of being concentric are offset relatively to one another. In order that the light flux collected by the reflector shall be a maximum the dimensions of the reflector should approximately be such that (d1/d2)<3> = (R1/R2)<2> R1, R2 being the radii of the ends of the reflector and d1, d, being the distance of the edges of the reflector from the light source.

Title: An improved process for obtaining bornyl and isobornyl esters
IPC: C07C35/30
Filed: 1928-08-13
Abstract: 306,387. Schmidt, L. Feb. 18, 1928, [Convention date]. Bornyl and isobornyl esters are obtained by first treating pinene or oils containing pinene with an organic acid and boron trioxide or mixed anhydrides of boric acid in the known manner, then removing the boron compounds from the reaction mixture and subjecting the resultant mixture of esters, excess organic acid, and unchanged pinene to a further heating in the pre-. sence of a small quantity of an acid catalyst, whereby the yield of esters is increased by 20- 25 per cent. Suitable catalysts mentioned are anhydrous oxalic acid, o-, m- or p-toluene sulphonic acid or their mixtures, orthophosphoric, nitric, sulphuric and hydrochloric acids. The process is illustrated in examples in which pinene is (1) heated with acetic acid and boron trioxide, the boron compounds removed by suction, and the mixture again heated after adding a little oxalic acid; (2) heated with acetic acid and acetoboric anhydride, the boron compounds removed, and the mixture reheated with a little ortho-phosphoric acid. In both examples yields of 70-75 per cent of esters are obtained, which may be purified and saponified in the usual way.
