Title: Electrical alarm instruments
IPC: G08B17/107
Filed: 1973-03-05
Abstract: 1394642 Smoke detectors ELECTRO SIGNAL LAB Inc 5 March 1973 [15 March 1972] 10527/73 Heading G1A [Also in Division G4] An alarm instrument for sensing a physical condition includes an alarm device, e.g. horn H, which operates in a first mode in response to a predetermined change in the physical condition, and in a second mode in a response to a circuit fault. The second mode is initiated by a pulse generator. As described, the instrument is a smoke detector, having a lamp DS-1 and photo-cells PC-1, PC-2 energized by an unsmoothed half wave rectified A.C. power supply. Pressure of smoke reduces the resistance of cell PC-1 until the potential at point 3 rises sufficiently for neon NE-1 to strike and trigger SCR Q2. Relay K in series with lamp DS-1 is energized to hold its contact in the K1 position, and horn H is energized, via SCR Q2, its inductance being sufficient to maintain current through it throughout. The whole cycle of the power supply input. A rise in temperature closes thermostatic switch TH to similarly trigger SCR Q2. If the lamp DS-1 fails, relay K releases, and its contact moves to the K' position to energize relaxation circuit R7, Cl NE-2 via the horn inductance, and to shunt the horn inductance by diode D5. In this mode the horn current is not maintained throughout the whole cycle and the horn is pulsed at a rate dependent on the time constants of the relaxation circuit.  In a modification, Fig. 2 (not shown). The relay K and its contacts are replaced by a transistor circuit.

IPC: D06B1/00
Abstract: 105,789. Andrew, T. April 25, 1916. Gases and vapours, treating with.-Yarn or other material is placed in receptacles g which are supported on gapped trollies h running on rails f through the conditioning chambers, the trollies being propelled either by projections s on a travelling chain r or by reason of the rails being inclined. The space beneath the line of trollies is divided by transverse partitions into three air entrance channels w and three air exit channels w<1>, which are connected to the delivery and suction sides of a fan, so that the air entering the apparatus through the channels w, passes through the yarn receptacles above them, along the upper part of the chamber, and downwards through the remaining yarn receptacles to the exit channels w<1>. With this arrangement, the several streams of air in the different parts of the chamber may be supplied with different amounts of moisture, and an independent supply of fresh heated air may be provided at the yarn-entrance end of the chamber. The chamber is provided with entrance and exit doors d, e which are connected together and balance one another, with elevators i, j for raising and lowering the yarn receptacles, with suitable knocking-off gear for automatically stopping the elevator mechanism with the yarn receptacles in their highest and lowest positions, with a travelling band e<1> for absorbing excessive moisture in the chamber, and with a runway beneath the chamber for the purpose of returning the empty trollies from the exit to the feeding end thereof Specification 6568/15 is referred to.

Patent GB-494091-A (GB)
Title: An improved photographic camera with means for automatic exposure adjustment
IPC: G03B7/12
Filed: 1937-04-15
Abstract: 494,091. Photographic cameras with photo-electric exposure meters. DZIEWIOR, K. April 15, 1937, No. 10791. Convention date, April 20, 1936. [Class 98 (i)] A camera including a photo-electric exposure meter for automatic exposure adjustment has several stop members selectively movable, in accordance with the setting of the pointer of the meter, into the path of a feeler connected with the exposure time or diaphragm adjustment means, and locking means, which are released upon winding of the shutter, for holding the said feeler in its initial position against movement in said path. Figs. 2 and 3 are sections at CD, AE, of the form shown in Fig. 1. The meter pointer z moves over the plungers a resting on a segment h pressed upwards by springs i. The spring d, wound by the knob b, drives the shutter. When one of the plungers a is depressed it forms a stop in the path of a segment g driven by the spring e through the gear f. This spring is wound by the knob c until the catch l on the gear f engages the projection m on the segment h. l and m also form the switch S, Fig. 5. When the pointer z has taken up its position the shutter spring d is wound. The cam surface p on the underside of the knob b depresses the segment k and with it the pointer z on to one of the members a. The segment h is thereby also depressed and the catch l released from the projection m so that the segment g moves up to the depressed plunger a, so setting the shutter speed. The tapping 1 on the resistance W is connected to the diaphragm setting ring which may be adjusted slightly if the pointer z has come to rest over the line of separation of two of the plungers a. The tapping 2 takes account of film sensitivity. If the light is very weak and the pointer is not deflected as far as the first of the plungers a the knob b is given an extra half turn during winding, thus moving the cam surface p past the ring k. No plunger a is depressed and the segment g thus moves right up to the point B at the end of its track to operate a switch U. This re-makes the photo-cell circuit. broken by the release of the catch l and also switches a shunt P out of circuit to increase the meter deflection. The shutter speed can then be adjusted manually from a suitable scale which is provided. Specification 483,775 is referred to.

Title: Method for making organic fertilizer
IPC: C05F17/02
Filed: 1949-04-26
Abstract: 672,913. Fertilizers. EWESON. E. W. April 26, 1949, No. 11081/49. Class 111 [Also in Group XIII] A method of making organic fertilizer by the decomposition of moist organic material through the propagation of aerobic bacteria therein comprises continuously forcing air under pressure through an enclosed mass of such material, all the air being introduced into the mass from the bottom thereof, and continuously withdrawing spent air which has passed through the mass and gases generated within the mass at vertically-spaced intervals throughout the mass. Waste materials such as garbage, sludge, and manure, waste and refuse from canning, fishery and sugar mills, and from distilleries and breweries, wood wastes, weeds, straw, tobacco stems, peat and the like are fed into an open-topped tank 1, Fig. 1, the resulting fertilizer being withdrawn from a conical bottom section 2 through a valve 3. Hot compressed air is supplied to a manifold 4 and thence to distributing pipes 6, Fig. 2, supported by crossbars 11, while used air and generated gases are withdrawn from similar arrangements of collecting pipes 6<SP>1</SP> and manifolds 4<SP>1</SP> communicating with outlet valves 15, spaced vertically in the tank. Arms 19 mounted on a rotating shaft 16 supported by upper and lower crossbars 17, 18, serve to agitate the mixture. An extension 27 carrying a bar 28 stirs the lowermost layer to facilitate discharge. The apparatus may be employed for batch operation, but is preferably used continuously. The tank is initially filled, air passed in, and only the lowermost escape valve 15 opened wide. As decomposition proceeds the continued introduction of fresh air begins to dry the lowest layer of material being treated, and as drying proceeds, decomposition is progressively inhibited. The next layer is then treated by either closing the lowermost valve 15 and opening the next higher one, or leaving the lowermost valve 15 open, opening the next higher one and increasing the total airflow by opening an inlet valve 14 wider. In either case. treatment is continued upwards progressively until all the layers are in a state of progressive decomposition from top to bottom. The material first discharged at valve 3 from below the distributors 6 is either discarded or fed in again at the top of the tank. With equilibrium conditions attained, raw material may be fed continuously or intermittently at the top of the tank and finished fertilizer withdrawn continuously or intermittently at the bottom. Pipes 29 for observation and withdrawal of samples may be provided. The preferred maximum air consumption is ¢ cubic foot per minute per cubic foot of material.

The purified solution does not form a precipitate with potassium ethyl xanthate and should be of the composition specified in Specification 528,112. A solution prepared from manganese ore may be treated.

The strip 20 then cools and draws the vane 14 back to its original position. The vane 14 has a slot 12 therein to provide a side strip 16 which is crimped to provide a means of adjusting the operating characteristics of the vane.
