Patent GB-842507-A (GB)
Title: Horizontal heat-exchange apparatus
IPC: F27D15/02
Filed: 1958-02-28
Abstract: 842,507. Cooling cement clinkers &c. FULLER CO. Feb. 28, 1958 [April 9, 1957], No. 6586/58. Class 51 (2). A heat-exchange apparatus for cooling a bed of discrete particles of material, e.g. cement clinker, comprises a chamber 1 with an inlet 5, an outlet at the opposite end and a horizontal series of overlapping alternately stationary and movable grates 7, 8 upon which the clinker rests. The forward portion of each grate is forwardly and upwardly inclined relative to the rear portion and the forward portion of each movable grate 8 is reciprocally moved over the rear portion of the next forward stationary grate 7 whereby the material thereon will be engaged and will be pushed forwardly and upwardly along the inclined portion of the grate 7 and spill over the forward end on to the next forward movable grate. The material is thus moved step-wise along the series of grates to the discharge outlet, the grates having apertures extending therethrough for the passage of cooling air to the clinker from compartments forming a plenum chamber 3 below the grates. The air after passing through the clinker leaves the cooling grates and passes over a sieve 46, the fines entering a pit 48 and the larger particles a clinker breaker 49. A conveyer 54 below the grates carries fines which have passed through the grates to the pit 48. Specification 519,018 is referred to.

Title: Improvements in or relating to spraying arrangements for spraying lubricant or the like by means of compressed air
IPC: F16N7/34
Filed: 1963-02-19
Abstract: 1,013,289. Spray producers. A. SCHMEMANN, [trading as DE LIMON FLUHME & CO.]. Feb. 19, 1963 [April 26, 1962], No. 6728/63. Heading B2F. [Also in Divisions B8 and F2] In an arrangement for spraying lubricant or the like by means of compressed air, an electromagnetic valve is mounted in an air-pipe and an air-actuated control-piston 2 and a lubricant feed-piston 9 are mounted in a spraydevice 1. In an embodiment, the piston 2 is urged by a spring 3 and pressurized air is supplied via a nipple 4, having a duct 4a therein which communicates with pipe 5 and 7. In use, lubricant is fed through an inlet 10 into an annular groove 2a, in the piston 2, which connects with a chamber 8a of the piston 9. Air is then passed by the electromagnetic valve (not shown) into the duct 4a of the nipple 4 so that a quantity flows through the pipe 5 to a nozzle-outlet 6 and the rest of the air actuates the pistons 2 and 9. Thus the annular groove 2a connects radial passages with the chamber 8a and the outlet 6 as shown in Fig. 2 and lubricant flows from the chamber 8a into the nozzle 6. When the electromagnetic valve is closed the piston 2 is returned by the spring 3 and the piston 9 is returned by lubricant entering the chamber 8a. The quantity delivered by the piston 9 may be adjusted by a screw 12, which is received by the body 1 and which has an extension 12a engageable with the piston 9. In another embodiment as the liquid to be sprayed is provided with additives in suspension, the liquid is continuously supplied by a pump to the nozzle so as to prevent the additives becoming deposited.

Filed: 1976-02-24
Abstract: 1506305 Discharging liquids SIEMENS AG 24 Feb 1976 [26 March 1975] 07323/76 Heading F1R A device for supplying a human or animal body with fluid comprises, a storage container 1 for storing a fluid medicament, a pressure generator 2 housed in container 1 and comprising a bellows membrane enclosing a substance having a superatmospheric vapour pressure at body temperature, an electro-mechanical flow control valve 8 arranged between the expulsion line 6 from container 1 and a fluid outlet catheter 7 and a pulse generator 9, whereby in use control signals from a programme transmitter 10 are received by a receiver coil 17 to control pulse generator 9 to operate valve 8 to allow the expulsion of pulses of fluid through catheter 7. The pulse generator 9, valve 8 and container 1 are mounted in an epoxy resin implantable housing 22, a battery, accumulator, fuel cell or plutonium capsule 20 powers the signal generator 9, and a receiver coil 17 receives the control signals. A flow limiter 19 comprising a capillary tube is provided between catheter 7 and valve 8 and limits the amplitude of the fluid pulses, the flow characteristics being adjustable by twisting the tube. A push button or magnetic switch 18 is provided as a further means of activating the valve 8 to give fluid pulses. A refill line 3 having a non- return valve 4 is provided to allow refilling of container 1. A pressure sensor 21 is provided so that the pulse generator 9 may respond to any increased pressure in container 1 due to increased temperature. The programme transmitter 10 includes a control signal emitter 11, a programme store and timing device 12, a programme introduction device 13, an information display 14 and an emitter coil 16. In a second embodiment, Fig. 4 (not shown) a second flow limiter is connected between the catheter 7 and expulsion line 6 to give a continuous flow of fluid between pulses. In a third embodiment, Fig.5 (not shown), the valve is used to switch between two alternative flow limiters connected to the catheter 7, and the valve is controlled by a position sensitive mercury switch so that the flow depends on the position of the patient. A fourth embodiment, Fig. 6 (not shown) has a flow limiter connected between the expulsion line 6 and the catheter 7, and the valve operates in one condition to allow flow of fluid into an auxiliary store, and in a second condition to deliver fluid in the auxiliary store toward the fluid outlet. A fifth embodiment, Fig. 7 (not shown), similar to that of (Fig. 4) has an auxiliary fluid store between the valve and the flow limiter 19.

Abstract: 1465854 Photographic processing apparatus AGFA-GEVAERT AG 18 Feb 1974 [17 Feb 1973] 7335/74 Heading G2X Photographic processing apparatus comprises (a) processing tank (1a) through which at least a portion of a circulation path for processing liquid passes, (b) means, e.g. a switch 16, for sensing photographic material passing through the tank, (c) means responsive to the sensing means for extracting liquid from the circulation path, and (d) means for maintaining liquid in the tank at a predetermined level, means (d) including means for supplying fresh previously uncirculated processing liquid to the circulation path to replace  extracted liquid. In the apparatus shown, a pump 5 powered by a motor (36) supplies processing liquid through a pipe 4 to tank (1a) which has a guide (3) for the liquid; the liquid level in the tank is maintained by an overflow 15, excess liquid flowing into a chamber lc for recirculation by the pump. In a stand-by condition, motor 36 supplies insufficient power for the pump to generate sufficient pressure, controllable by a screw 9, for liquid to be forced out of the top of a riser 10. When the presence of photographic material to be processed is sensed by a switch (16), motor (36) is pulsed at a higher output which increases the liquid pressure sufficient to force some of the recirculating liquid out of riser 10 into a drainage channel (11). Liquid so discharged or used is replenished from an inverted bottle 13, having a valve which is operated by a pin (14).

The alkoxy groups are saturated and contain up to four carbon atoms each.  Suitable reactants are dimethyl diethoxy silane; methyl triethoxy silane; diphenyl dimethoxy silane; phenyl trimethoxy silane; trimethyl phosphate; trimethyl borate.  The reactants are preferably employed in stoichiometric proportions.  The products are linear, cyclic or cross-linked depending on the functionality of the reactants.  Mono-functional alkoxy compounds or a tetra-functional alkoxy compound of silicon, e.g. ethyl-o-silicate may be used in the reaction.  In the example trimethyl phosphate is heated with tetra methyl silicate in a bomb tube for 8 hours at 200 DEG C. and 8 hours at 250 DEG C.
