Title: Improvements in and relating to powder spray devices
IPC: B05B7/14
Filed: 1959-01-06
Abstract: 910,834. Powder sprayer. WARHURST, W. J. April 5, 1960 [Jan. 6, 1959], No. 478/59. Class 69 (3). A reciprocatory plunger 29, grooved at 41, feeds powder from a container 2 through an orifice 50 to a space within a plate 38 which houses a nozzle 16 through which air is intermittently emitted to spray the powder from an outlet 39. Compressed-air is intermittently supplied to a union 20 and flows via a valve 18 and duct 22 to one side of a diaphragm 23 to which one end of the plunger 29 is attached. Forward movement of the plunger is effected by the air pressure, and return movement by a spring 28; as shown, the plunger slides in a liner 30 provided with a flexible sealing sleeve 36. The plunger stroke and hence the number of powder extracting grooves that can pass from one side to the other of the hole 50 are regulated by a shaft 25 with an enlarged head which is urged against the diaphragm by a spring 32. The forward position of the shaft is regulated by a knob 34 having a notched cam surface engaging a tooth 43. Some of the compressed-air fed to the union 20 flows through ducts 15, 14, chamber 12 and nozzle 16; air is drawn into an opening 40 by the air flow from the nozzle, and entrains the powder in the plunger grooves and carries it from the outlet 39 together with the main air stream. The air supply to the chamber 12 reciprocates a plunger 11 connected to a diaphragm 8 to prevent compaction of powder in the container.

Title: Display tube arrangement for storing and erasing information
IPC: G11C11/23
Filed: 1972-01-05
Abstract: 1380088 Transistor pulse circuits; cathode-ray tube circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 Jan 1972 [8 Jan 1971] 510/72 Headings H3T and H4T The storage screen-to-cathode voltage of a storage type cathode-ray display tube is provided by an emitter follower and an erasing voltage from a CR differentiating circuit fed with square wave source is added to the D.C. voltage, the circuit being arranged so that it can use a transistor having a peak voltage rating less than the peak screen-cathode voltage so generated. In Fig. 1, the square wave generated by switching over contact 12 is differentiated by a capacitor 16 and the associated resistance and the resulting pulses are applied to the base of the emitter follower supplying the screen-cathode voltage so as to superimpose positive and negative pulses thereon. Capacitor 17 connected in a circuit having the same time constant as the circuit of capacitor 16 maintains the collector voltage at a safe value. In Fig. 2 not shown), the differentiating capacitor is in series with the emitter follower, the supply to the latter being allowed to float and having a capacitor across it to maintain the voltage steady when the pulses are added. In Fig. 3 (not shown), the differentiating capacitor is connected to the emitter via a diode which isolates the transistor during the positive portion of the pulse, the transistor being driven to saturation during the negative portion so as to maintain the voltage thereacross low. A further diode and resistor (24, 25) are provided to equalize the charge and discharge time constants. In Fig. 4 (not shown), the capacitor is connected to the base and the collector-base p diode is protected by a Zener diode which conducts forwardly during the positive portion of the pulse and reversely during the negative portion. The tube is of a type having a glass screen coated by a thin conducting layer carrying a phosphor. The screen is sprayed with a uniform stream of electrons and a writing gun supplies relatively high velocity electrons which causes the screen, at the point of impact, to have a secondary emission factor greater than unity so that it acquires a positive charge.

Abstract: 665,116. Making commutators. BOSCH GES., R. Jan. 8, 1949 [Oct. 1, 1948], No. 602/49. Class 83 (ii). [Also in Group XXXV] A moulded commutator is made by gouging hook-shaped chips 30 from the surface of a metal bar which has previously been divided into segments by slots 28 and then bending it round and setting in moulded material, the segments being separated by machining. Sheets of insulating material may be placed in the slots between the segments before moulding and connecting slots or tags may be formed on the edge of the strip. Each segment may have two pairs of hooks and the inner hub may be provided with turned-over annuli on its surface to grip the plastic. It is stated that the process of gouging out the chips may be used on cylindrical blanks. The Specification as open to inspection under Sect. 91, states that the commutator may be made by inserting blades, which may be specially shaped to grip the plastic, into lateral slots in the face of a strip which is subsequently bent round into circular form for moulding. This subject-matter does not appear in the Specification as accepted.

IPC: H03D7/16
Filed: 1987-05-21
Abstract: Mixer arrangement (M) comprising first and second quadrature mixer stages (M, resp. M<sub>2</sub>) to which quadrature mixing signals are applied from an oscillator circuit (Fo), these two mixer stages (M, and M<sub>2</sub>) being coupled to a superposition circuit (So). To suppress interferences occurring in the output signal of the superposition circuit due to oscillator crosstalk or leakage and/or a d.c. offset of the mixer stages (M, and M<sub>2</sub>) which are supplied with mixing signals by the oscillator circuit Fa, the quadrature components of these interferences being in phase with the quadrature mixing signals are measured by means of first and second synchronous detectors (SD<sub>1</sub> resp. SD<sub>2</sub>) to which detection carriers are applied in an in-phase or an anti-phase relationship with respect to the quadrature mixing signals. After sign inversion these quadrature components are fed back to the inputs of the two mixer stages (M, and M<sub>2</sub>), resulting in an interference negative feedback.

Title: Combustion device
Inventor: NARUSE SHIGEO
IPC: F23N5/24
Filed: 1986-01-07
Abstract: PURPOSE:To stabilize the combustion in a second burner in a collective exhaust type burner by a constitution in which a proportional second burner increases in its small capability the rotational speed of a fan during the operation of an ON-and-OFF type first burner of forced blast type with a fan. CONSTITUTION:A fan 2d starts its rotation and a second burner 3 operates when a switch (not shown) is closed and slow ignition is performed, and at the time the fan 1d of a first burner 1 also starts its rotation. The blast of this fan 1d is always constant, but the blast from the fan 2d of a second burner 3 changes from an area which is smaller than the blast of the fan 1d to the area of much larger blast. In this case the fan 1d of the first burner 1 is in operation and increases the rotational speed of the fan 2d when the second burner 3 is in operation at its small capability, so that it can overcome the blast pressure of the fan 1d of the first burner 1. With this constitution, the combustion of the second burner 3 can be stabilized.
