Title: Electrostatic recording apparatus
IPC: G03G15/05
Filed: 1975-03-04
Abstract: 1494707 Printers HITACHI Ltd 4 March 1975 [6 March 1974] 8946/75 Heading G4H [Also in Division H1] An electrostatic recording apparatus comprises a plurality of wire electrode groups each constituting a block, the corresponding same-ordered wire electrodes of the respective blocks being simultaneously scanned, a pair of auxiliary electrode rows 4A 1  to 4A n  and 4B 1  to 4B (n+1)  provided respectively along both sides of and opposite to the wire electrode groups, the auxiliary electrodes of one row being staggered relative to those of the other row and each of the auxiliary electrodes having approximately the same length as that of each of the blocks, and a scanning circuit 7 for scanning the auxiliary electrodes. The auxiliary electrodes 4A 1  to 4A n  are sequentially scanned. The auxiliary electrodes 4B 1  to 4B (n+1)  are divided into two groups which are scanned alternately. An information signal applied to a DATA terminal of the wire electrode drive signal generating cricuit 5 is distributed to terminals P 1  to P m  by a clock pulse applied to terminal C p  and a synchronizing signal is fed to the auxiliary electrode generating circuit 7. The division of the auxiliary electrodes 4B 1  to 4B (n+1)  into two groups reduces the number of connections and driving circuits required. In alternative embodiments: the auxiliary electrodes 4A 1  to 4A n  are divided into two groups (Fig. 5, not shown); the auxiliary electrodes 4B 1  to 4B (n+1)  are divided into four groups in each of which alternate electrodes are at the same potential (Fig. 6, not shown); or the auxiliary electrodes in both rows A and B are energized individually (Fig. 8, not shown). A block diagram (Fig. 10, not shown) of the components of circuits 5 and 7 is provided together with matrix and drive circuits (Figs. 11-15, not shown) for connection to the wire and auxiliary electrodes.

Void [Published under Sect. 91 of the Acts]. [Classes 29 and 64 (ii).] Refrigerating, compression machines for ; refrigerating chambers; thermostats.-A railway refrigerator car is adapted to be cooled in summer and warmed in winter by a refrigerating machine in which the flow of the refrigerant may be reversed, so that the evaporator inside the car becomes the heat-delivering condenser of the system when arranged for heating. The system for a condensing compression machine comprises a. compressor 1, Fig. 1, condenser 2, regulating valve 4, evaporator 3 and connecting pipes with stop valves. The condenser or evaporator may comprise vertical tubes between upper and lower headers, the lower headers being fitted with valves 33, 34 and pipes 31, 32 for returning oil to the compressor suction. The regulating valve may be of the float type and connected so that the condensed refrigerant passes therethrough in one direction only, from a pipe 21 or a pipe 22, and through a pipe 25 to one of two valved branches 26, 27. The delivery and suction pipes 7, 12 are connected by cross pipes 9, 14 and are valved for reversal of flow. Where a handregulated expansion valve is used it is placed in a single pipe connecting the lower headers. The condenser may be situated outside the vehicle and protected from the sun's rays by boards. The air of the chamber may be circulated by a fan coupled to the compressor. An air delivery duct 37, Fig. 3, is arranged in the chamber above the evaporator coils 3, and side and bottom ducts 40, 42 communicate through valves 44, 45 with a suction duct 39. The valves are set in correspondence with the setting of the refrigerating system. The fan 46, Fig. 6, and compressor 47 may be driven from an internal-combustion engine 48 through epicyclic gearing in a casing 51, which when held stationary by a band brake 54 transmits the drive, and when free rotates and leaves the refrigerating machine out of action. The brake may be controlled thermostatically to maintain an even low or high temperature. As shown in Fig. 7, a double switch 68, 69 of the circuit of an electromagnet 74 connected to the brake 54 is controlled by the bellows member 65 of a thermostatic capsule 63. Alternatively the bellows member may control a hydraulic system, Fig. 8, including a pump 86, pressure cylinder 88, tank 91, and connecting pipes, for operating the brake.

Lathes ; rolling.-In a device for cutting circumferential notches in the rollers a of rolling mills the roller is mounted in a lathe and the grooves 1 .. 7, Fig. 1, are notched by a tool o, Fig. 4, which is fed to and from the work by means of a cam i mounted on a shaft d driven in timed relation with the roller through gears e .. h at a speed depending on the number of notches to be cut. The tool is mounted on a carriage c sliding on ways b. In some cases the tool may have two cutting portions, Fig. 2, each having a radius of curvature somewhat less than the curvature of the roller groove so that two series of notches are cut simultaneously. After a complete rotation of the roller, the tool may be reset to take a deeper cut either by means of a screw p or automatically. The cam i is preferably shaped so as to cut a notch which slopes gradually on one side and steeply on the other side, as shown in Fig. 4. In some cases the gearing may be arranged so that the tool cuts every second, third or fourth notch during one rotation of the roller.

Title: Apparatus for burning cement raw materials
IPC: C04B7/44
Filed: 1975-03-06
Abstract: The device serves for burning cement raw material in a dry process for producing clinker, the calcination of the raw material taking place predominantly outside a rotary kiln. The device comprises a shaft preheater with two parallel branches, a calcining chamber (5), a rotary kiln (1) and a clinker cooler (4). The waste gases from the rotary kiln are fed to one branch and the waste gases from the calcining chamber are fed to the other branch. The calcining chamber (5) is coaxially connected directly to the shaft (2) of the preheater branch of the calcining chamber. In addition, the pipe (9) for discharging the preheated raw material from the shaft (3) of the preheater branch of the rotary kiln (1) is connected to the pipe (7) for the preheated air, leading into the calcining chamber (5). In the calcining chamber, good thorough mixing and spreading of the raw material takes place, so that the entire cross-section thereof is utilised. <IMAGE>

Title: Improvements in or relating to piezo-electric devices
IPC: H03H9/05
Filed: 1928-03-29
Abstract: 312,444. Gramophone Co., Ltd., Whitaker, A., and Eccles, W. H. March 29, 1928. Light-valves.- A piezo-electric crystal, maintained in vibration at high frequency, has its damping varied at acoustic or low frequency. As shown, the crystal 1 silvered on its opposite faces is supported on an insulating plate 5 between the poles 2, 3 of an electromagnet. A coil 4 mounted on the magnet yoke carries audio-frequency currents which vary the magnetic flux through the crystal and so vary the eddy currents in its silvered surfaces. The damping, and therefore the amplitude of the crystal vibration, is thus varied at audiofrequency. In a modification, the audio-frequency currents set a diaphragm in vibration, and the diaphragm varies the damping of the crystal either by variable pressure on, or by variable air spacing from, the crystal surface. The apparatus may be used for modulating a beam of light in accordance with sounds. Specification 305,074 is referred to in the Provisional Specification.
