Title: Improvements relating to pre-payment meters
IPC: G07F15/06
Filed: 1926-07-29
Abstract: 256,249. Allgemeine Elektricitõts- Ges. July 29, 1925, [Convention date]. Mechanism for prepaying rent of meter. - A prepayment meter for electricity and the like having means for charging initial or rental fees, is provided with a locking device so connected to the prepayment meter that, upon the rental fee falling due, the supply is cut off independently of the position of the prepayment mechanism and is resumed upon the payment of the fees due. The nose or pawl 11, Fig. 2, of the locking lever 6 which is controlled by the prepayment locking bar or spindle 8 and retains the switch disc 2 in closed position, is rotatable about the pivot 12 and is prevented by a toothed segment 14 engaging it from releasing the disc 2. The segment 14 is controlled by a spring 15 and is held in locking position until the rental fee falls due by a locking device 13, which is operated in any known manner. The meter may display a signal when the rental fee becomes due. The Specification as open to inspection under Sect. 91 (3) (a) comprises also means for operating the locking device 13. The device 13 is carried by a lever 17, Fig. 3 (Cancelled), having a projection 19 which rides on a notched disc 16 rotated once a month by an operating mechanism running at constant speed. When the notch 20 comes opposite the projection 19 a spring 21 moves the lever 17 to release the pawl 11 and to disengage a toothed wheel 18 from a wheel 24 on the spindle of the segment 14. If coins be now inserted and a knob 10 rotated, an arm 23 connected to the disc 16 moves with an arm 22 connected to the knob and disengages the projection 19 from the notch in the disc. The wheel 18 is also engaged with the wheel 24 so that further rotation of the knob returns the pawl 11 to locking position. The number of rotations necessary is determined by the position of a stop for the pawl. This stop 26, Fig. 4 (Cancelled), is set by levers 27, 28, the end of the lever 28 indicating the number of coins to be paid as rental fee. The stop 26 may be set by a clock, relay or by a collector. In order that due payment of the fee shall prevent stoppage of the supply, the disc 16 may disengage the prepayment mechanism from the switch spindle and is itself connected up to the latter shortly before the time for the payment of the fee. The disc 16 may be so constructed that it is possible to pay the rental fee for several periods in advance. This subject-matter does not appear in the Specification as accepted.

Filed: 1926-07-29
Abstract: 269,471. Skinner Automotive Device Co., Inc., (Assignees of Skinner, R. L.). April 17, 1926, [Convention date]. Recovering waste lubricants. - Excess lubricating oil is withdrawn from grooves in the reciprocating sleeve or sleeves of a sleevevalve internal-combustion engine by suction through a port 26 in the wall of the cylinder 11 vertically below the fuel inlet port 12, so as to prevent such oil from being drawn into the inlet port 12. The sleeve, or, in the case of a multi-sleeve engine, the inner sleeve is imperforate, except for the usual inlet and exhaust ports. In an engine having two sleeves 14, 15, both sleeves are provided with external circumferential oil grooves 24, 25, the outer sleeve 15 being provided with a longitudinal slot 37 in register with the port 26. A pipe 27 connects the port 26 to a manifold 28. and a pipe 29 connects the manifold 28 to a passage 31 in the cylinder wall in alignment with the ports 12, 26 and leading into the annular sealing- head compartment 32 above the sleeves. At a point opposite the passage 31. the compartment 32 is connected by a passage 33 and a pipe 34 to a manifold 40, which is connected by a pipe 30 to an oil separator 35, the top of which is connected to the intake manifold of the engine by a pipe 36. The manifolds 28, 40 are common to all the cylinders of a multi-cylinder engine. Oil is thus withdrawn by the suction in the intake manifold from the upper oil grooves of both sleeves and is delivered into the separator after passing through the compartment 32, where it lubricates the upper ends of the sleeves. The upper part of the separator is enclosed by a casing through which exhaust gases pass from the exhaust port 13 through pipes 38. Reclaimed oil passes to the crank case from the separator through a pipe 39. In the case of an engine with only one sleeve, a longitudinal surface groove on the sleeve registers with the port 26. Specification 249,715, [Class 122 (i), Engine and like cylinders &c.], is referred to.

Patent GB-192532-A (GB)
Abstract: 192,532. Petter, G. B. Nov. 24, 1921. Counting-apparatus with variable-step movement.-In counters for calculating machines having a row of figure discs loosely mounted on a common spindle, two discs each are employed for some or all decimal columns or corresponding denominational groups of figures in non-decimal systems of rotation such as money systems. This arrangement dispenses with the necessity for large angular movements of the discs. The discs can be rotated by any suitable means to bring a selected member opposite a window, and they may be provided with any suitable carrying mechanism. In the particular example shown, the discs A, B represent pounds, the discs C, D shillings and the discs E, F pence. The sequence of figures on each disc is repeated a plurality of times around the periphery, for instance, the discs B, D may have twenty-five figures and the discs A, C, E, F twenty-four figures. In reading the result, the totals for the various denominations must be determined mentally. In the example shown, ú9 17s. 11d. would appear in the window as 5, 4; 15, 2; 9, 2.

Title: Electric brake controller
IPC: F16D65/28
Filed: 1972-04-27
Abstract: 1371271 Brake-fluid- or hand-operation of electrical brake controller KELSEY-HAYES CO 27 April 1972 [1 June 1971] 19590/72 Heading F2E [Also in Division H1] An electric brake controller for controlling the magnitude of current to electrically-actuated brakes comprises a control resistance winding wound about a longitudinally extending axis, a flexible conductor extending longitudinally relative to the axis and spaced from the control winding, support means generally fixed relative to the control winding for supporting the flexible conductor as a beam at both ends, and actuating means operatively connected with the flexible conductor for applying a force to the conductor at a location between its ends so that the conductor as a result of beam bending thereof is engageable with the coils of the control winding. As shown, the flexible conductor 76, preferably of resilient phosphor bronze, is backed along part of its length by a support member 78, preferably of spring steel. One end, 64, of conductor 76 is screwed down at 67 on to one end of a dielectric core member 16 and is connected at 68 to battery B; the other end of conductor 76 is slidably supported in a slot 72 of a portion 74 of the core member 16. One end of resistance winding 18 is connected to a contact tab 42 and to brake light L, while the other end is connected to another contact tab 58 and to an electromagnetic brake coil C. Conductor 76 and support member 78 forming conductor assembly 12 are connected together by a locking tab 96 on one leg 94 of a "load block" 88, the other leg 92 contacting the conductor assembly 12. Load block 88 is accommodated in a slot 126 of a control member 124 threaded on to an actuating rod 112, the rod 112 being received in a pivot member 100. Pivot member 100 pivots in the housing 17 and cover (19, not shown) and is contacted by the piston of a piston assembly 10 subject, for example, to hydraulic pressure at 123 from the brake system of a towing vehicle, where electromagnetic brake C is on a trailer vehicle.  In operation, as the towing vehicle brakes are applied, the piston rotates pivot member 100, causing control member 124 through load block 88 to flex conductor assembly 12 downwards. Conductor 76 first engages contact tab 42, so brake light L is energized. As the conductor assembly is flexed further, the turns of winding 14 are progressively shorted out, so that increasing energizing current is supplied to coil C. The velocity ratio of the apparatus is such that only a small amount of brake fluid is needed; the velocity ratio can be varied by rotating knob 120. The rod 112-pivot member 100 assembly can be moved by knob 100 to provide control of brake coil C independently of the piston assembly 10.

Title: Preheater for oil burners
IPC: F23K5/20
Filed: 1957-06-24
Abstract: 846,752. Heating by friction. ROBINSON, T. O. June 24,1957 [June 25, 1956], No. 19821/57. Class 64(2) [Also in Group XXVI] Fuel oil for a burner is preheated by a friction disc 37 having a ring of twelve holes 38 and driven by a shaft 16 of a gear pump on which shaft the disc 37 and a gear wheel 26 are mounted for rotation by the shaft and there may be heat exchange between the oil passing to and from the pump. There may be a further friction disc through which the oil passes as it leaves the pump chamber 2. The shaft 16 passes through central holes in three discs 17, 22, 32 secured by four bolts to the back of the pump housing. A ring 42 screw-threaded on to the outer edge of the gear-housing disc 22 has an internal flange 43 which bears against a disc 39 held from rotation by the engagement of edge notches with pins 36 on the disc 32. The friction disc 37 being sandwiched between the fixed disc 32 and the axiallymovable disc 39, the pressure on it, and therefore the friction produced, may be increased by tightening the ring 42 on the disc 22. The second gear wheel rotates on a pin secured to the back disc 17 and the two wheels, by way of ducts, Fig. 4 (not shown), formed in the rear face of the disc 22, draw oil from the pump chamber 2 through a duct 31, formed by the coincidence of holes each formed in one of the discs 22, 32 and 39, and pass it to an outlet duct formed by a hole 20 in the rear plate 17 and a bore 8 in the back of the pump housing. In the passage to the burner from the bore 8 is a piston valve 10, spring loaded to open under pump pressure and to regulate the outflow. The holes 38 in the rotating friction disc 37 successively coincide with the duct 31 and are not so widely spaced that they ever completely close it. Any oil not passed to the burner may be returned from the chamber 3 of the regulating valve 10 partly to the pump chamber 2 through a duct 12 and partly to the oil tank through another duct in the pump housing 1, Fig. 2 (not shown, but which indicates also two inlets to the chamber 2 of which one may receive oil returned from the burner.
