Title: Improvements in or relating to gramophones and the like
IPC: G11B3/38
Filed: 1928-02-06
Abstract: 311,302. Walter, C. M., Marsh. R. G., and Charles, W. J. Feb. 6, 1928. Electric pick-ups, mounting and supporting.-Consists in a mounting or support for an electric gramophone pick.up, comprising in combination a carrier on which the pick-up is mounted, and a guide therefor along which the carrier and pick-up can travel radially across the record during sound - reproduction, the mounting being such that the pick-up is free to be rocked in a plane at right angles to its line of travel. In the construction shown in Figs. 1 and 2, an arm 1 of aluminium or the like is fixed so as to extend over the turntable parallel to a radius of the record. Rollers 6, 7 are mounted in brackets 4, 5, the bracket 4 being fixed directly on the arm 1 and the bracket 5 insulated therefrom. The pick-up 8 is attached to a lug 9 which has at one end a disc 10 clamped between discs 11, 12 and insulated from the latter. The discs 11, 12 are secured to rods 13, 13' respectively, which are in exact alignment, and rest on the rollers 6, 7. To avoid the use of long electrical leads, connection is made to the pick-up from terminals 19, 22 through the rods 13, 13<1>, the terminal 19 and the connections therefrom (including the. rod 13) being earthed, while the terminal 22 and its connections to the pick-up through the rod 13<1> are all insulated. The mounting of the pick-up not only permits it to travel so that the stylus moves truly radially across the record, but also enables it to be swung about the axis of the supporting rods, for changing the needle and to allow for the slight up and down movements occurring during playing. Fig. 4 shows a simpler construction, in which a carriage 25 for the pickup 8 is mounted on rollers 26 which travel along a fixed rod 23. Flexible leads are in this case taken from the pick-up. A modification of the arrangement shown in Fig. 4 is described in which the fixed rod is divided into two parts, the outer one being insulated from the other. The parts of the rod serve as current leads. A further construction, similar in general arrangement to that shown in Fig. 1, is described, in which the fixed arm and the lug carrying the pick-up are both made of moulded insulating material. The adjacent ends of the aligned rods are moulded into the carrier lug, and are connected by internal leads to the pick-up, while leads from the rollersupporting brackets pass inside the fixed arms to terminals near its base.

An ultrasonic generator comprises an aluminium disc 10 formed integrally with a mounting pin 15. When suitably excited, the disc vibrates on a flexural mode with nodal diameters d 1 , and d 2 . One disc may generate two separate frequencies or a combination of the two frequencies. The disc may be excited by a piezo-electric crystal 50, Fig. 8, or by one or more strikers. A striker-head 42 is carried ona spring 41 mounted on a cover 30. The striker-head Figs. 1, 3 has access to the disc through hole 34 and two holes 33 disposed over opposite sectors B, D of the vibrating disc act as two in-phase sources of ultrasonic vibrations. The cover 30 is spaced from the disc by distances S 1  S 2 , S 3 , as shown, each of which is an odd number of quarter-wavelengths. Generation of different frequencies. The disc 110 is drilled with four holes 115 as shown in Fig. 9 Strikers 142, 146 excite vibrations with nodal diameters d 1 , d 2  and d 3 , d 4 . In one of these modes, the holes 115 are confined to nodes and in the other they are located at antinodes. The frequencies differ. Striker 144 excites both frequencies. Other patterns of holes 118, 119 may be drilled as shown in Figs. 17,18,19.

Abstract: 177,325. Gibbs, G. J. Feb. 1, 1921. Roller - and - sheet recordinp-apparatus. - Relates to time-distance and rest-or-motion recorders especiallv for vehicles, and consists in an instrument in which the record is in the form of a line made by a scriber on a paper strip which is fed according to the movement of the machine to which the instrument is attached, the scriber being moved across the strip by clockwork so that the forward strode is made uniformly and the return stroke suddenly, the return stroke also imparting an intermittent movement to the strip when the machine is at rest, to give a record of the time during which the machine is standing as well as a time-distance record. The recordstrip 12 passes round a drum 3 an extension of which carries clutch rings 7 and 8, the former being also a worm-wheel driven by a worm 4 on a shaft 5, which is caused to rotate by suitable means at a speed proportional to that of the machine. Each clutch is adapted to drive the drum only when turning in one direction by means of spring-controlled balls in wedgeshaped recesses in the drum. The scriber 11 is carried by a reciprocating arm 10 which has a finger 14 pressed by a spring 20 against a cam 2 rotated by the clock work. The engagement of a projecting stud 18 on the clutch ring 8 in a slot 21 on the arm 10 inclined to the axis, gives a to-and-fro movement to the ring which imparts a small intermittent movement to the strip when the machine is at rest.

Title: Control valve for positive crankcase ventilations system
IPC: F01M13/02
Filed: 1972-01-27
Abstract: 1358797 Ventilating crank-cases;treating charge FORD MOTOR CO Ltd 27 Jan 1972 [31 March 1971] 3912/72 Heading F1B [Also in Division F2] In an I.C. engine having a ventilated crankcase and an intake manifold a valve provides a variable restriction in a passage between the crank-case and the intake manifold in response to intake manifold pressure, the response of the valve being delayed upon a sudden change in intake manifold pressure. Crank-case gases pass via port 27, orifice 29 and port 28 to a line (20) Fig. 3 (not shown) leading to the inlet manifold. The orifice 29 is controlled by a tapered plunger 31 moved by a diaphragm 36 acted on by ambient pressure in chamber 34 and inlet manifold vacuum in chamber 33 communicated to port 39 from line (20). At low speeds the plunger 31 is positioned to restrict the flow of crank-case gases and as engine speed increases with consequent decrease of inlet manifold vacuum the plunger 31 is moved to permit full gas flow. On sudden acceleration from a low speed the decrease in the inlet manifold vacuum causes a valve element 54 to seat on surface 51 to delay the equalization of pressures in manifold 19 and compartment 34. Thus the onset of full gas flow through orifice 29 is delayed during acceleration.

Abstract: 576,746. Elastic-fluid turbines. JAMES, R. F. March 2, 1944, No. 3924. [Class 110 (iii)] The rotor 1 of a turbine used for jet propulsion contains one or more rings of venturishaped tubes 14 through which compressed combustible gas is forced to be ignited by plugs 15, the gases passing through a venturishaped chamber 10. Gases flowing through the tubes 14 cause rotation of the rotor. A fairing cone Q is attached. Air may be entrained in each tube 14, and fuel injected into the tube. The rotor is mounted on a shaft 2 supported in bearings 3, 4, and provided with a thrust bearing 5. Fuel is supplied by a pump to a pipe 18 and to a series of float chambers which feed jets 19 extending into venturi passages 9 through which air is flowing. A starter 28, which may be of the cartridge, electric or other type, gives the initial rotation to the rotor and causes air flow through a spider 6 and passages 9. A rotary pump 20 circulates cooling medium from a pipe 21, connected to a radiator, through pipes 22, 23, and a space 24, pipes 26 leading back to the radiator. Cooling fins 11 are provided. Regulation of the air flow may be secured by dampers arranged across the inlet end of the casing 8. A ring of turbines may be arranged vertically within the wing of an aircraft to give upward lift. The fuel may be pre-heated.
