Abstract: 1,170,850. Heating, cooling and air-conditioning greenhouses. M. CONANGLE. 21 Nov., 1967 [13 Feb., 1967; 18 Oct., 1967], No. 52995/67. Headings F4U and F4V] In a double-walled horticultural conservatory or greenhouse, inner and outer metal framework members 2, 3 are covered by sheets of glass 4, 5 and spaced apart by stays 1 to define therebetween a space through which hot or cold air and/or water is circulated to produce and maintain the required temperature and hygrometric conditions within the greenhouse. The inner glass wall has a gap 6 at its apex, thus communicating the space with the inside of the conservatory. Pipes 7, 8 are situated adjacent the gap 6 to spray hot or cold water over the inner wall, this water being collected in tanks 10 for recirculation by pumps 9. Reversible fans 11 deliver air to or extract air from the conservatory through said space as required, to ensure suitable ventilation. Gas or oil burners (not shown) are provided to heat the water in the tanks 10, and the combustion gases from said burners may be passed into the space if required for additional heating. Thermostats and hygrostats automatically control the operation of the fans, pumps and burners to maintain the required conditions. The amount of light entering the conservatory can be reduced by spraying water tinged with colour into the space between the two glass walls. In an alternative embodiment (Fig. 2, not shown), the spraying pipes together with associated atomizing nozzles (8<SP>1</SP>) are located adjacent the tanks (10<SP>1</SP>). Air is introduced at this point and entrains some of the water, the moistened air then passing up through the space and into the conservatory.

Abstract: 1367332 Clay guns for furnace tap holes DES ANICENS ETABS PAUL WURTH SA 18 Nov 1971 [27 Nov 1970 3 June 1971] 53708/71 Heading F4B A clay gun 1 is supported at one corner C of a quadrilateral linkage having three movable arms. A fixed arm 4 is secured to a base 16, between a pillar 19 forming a pivot A for an arm 3 supporting the clay gun, and a pivot B for a controlling arm 5. The fourth arm of the linkage is formed by part of the clay gun. The pillar 19 is inclined to the vertical, preferably perpendicular to the tap hole axis. The clay gun 1 is supported by pivot pins 27 in a fork 24 pivoted to the support arm 3, and adjustable links 25 enable the gun to swing about the pivots 27. The control arm 5 is adjustable in length by means of a screwed sleeve 11 so that the gun may be swung about the pivot of the fork 24, so that small variations in the position of the taphole can be compensated. A piston 20 pivoted to the arm 3 at 23 enables the gun to be moved through the path shown in Fig. 3. The operating piston may be linked to the support arm 5 through a stirrup pivoted to the piston at an intermediate point, to the base at one end, and to a link pivoted on the support arm at the other end, so that the clay gun can be swung through 180 degrees, Figs. 8-10 (not shown). The hydraulic piston 20 is connected to operate as a differential piston to move the clay gun to and from the washing position, and as a direct pressure cylinder to hold the clay gun against the tap hole. The operating fluid for the mud piston of the clay gun is fed to the gun through the pivot of the fork 24, Fig. 7, which is supported on the end of the arm 3 by roller bearings to reduce the effect of the reactive force of the clay gun. The pressure fluid flows in and out through pipes 55, 56 housed in the supporting arm 3, and these are connected through passages in a valve body within the pivot of the fork 24 to passages 45, 44 connected to the clay gun piston. A similar device is arranged at the pivot point A. The hydraulic control system is remote from the furnace, and may include an electro-hydraulic power-drive system, and/or an hydraulic accumulator so that the fluid supply can be maintained in case of current failure. Several tap hole plugging units may be supplied from a single accumulator.

Abstract: 1,243,250. Thermocouples. SIEMENS A.G. 14 Nov., 1968 [15 Nov., 1967], No. 54178/68. Heading H1K. A thermocouple comprises two limbs 2 joined at their hot ends by a conductive bridge 3a or 3b forming part of a first heat exchanger, while the cold end of each limb 2 carries a metal plate 5 provided with a terminal lug 6. A screwthreaded pin 9a or 9b, e.g. of Ag, is also attached to the cold end to allow the couple to be secured to a second heat exchanger 11, e.g. by means of a nut 10 or directly, as 9b. In the former case the pin 9a may be provided with an expansion cavity 13. One or two ceramic plates 8a or 8b metallized on both sides electrically insulate the pin 9a or 9b from the plates 5, which may be of Ag. The plates 8a or 8b are soldered to both the pin 9a or 9b and the plates 5. W plates are situated between the Ag plates 5 and the limbs 2. Ag braids 7 interconnect adjacent couples in the thermoelectric generator illustrated. In modifications, Fig. 2 (not shown), the terminal lugs (17) themselves comprise two mutually insulated halves of a split screw-threaded pin secured to the cold heat exchanger (11) by an insulating nut (19). Ceramic members (18 or 21 and 22) insulate the pin from the exchanger (11), while flanges on the respective halves of the pin provide the plates (5). Fig. 1 shows two alternative forms of hot bridge, 3a or 3b, both of which comprise an inner foot enclosed within and preferably sintered or soldered to an outer shoe 15a or 15b. Preferred materials for the bridge are specified. The bridges mosaic together, e.g. as an array of either squares or hexagons, separated by insulating material 24, to define the hot heat exchanger. The outer surfaces of the bridges may be pyramidal or domed to increase the effective heat exchange area, which may be heated by radiation or a flame. In the modification of Fig. 2 (not shown) each bridge (3) extends laterally only as far as the thermocouple limbs (2) and a thermally non-conductive apertured support plate (23) fills out the space between the bridges (3).

Abstract: 1,165,932. Hay balers. INTERNATIONAL HARVESTER CO. 5 Dec., 1966 [6 Dec., 1965], No. 54272/66. Heading B5F. A pick-up 11 for a hay baler has its centre line offset from the longitudinal centre line of the baler towards a first side of the baler, packing fingers 55 for feeding and packing picked-up material into a baling passage 14, the longitudinal axis of which extends rearwardly of the baler at an angle A to the longitudinal centre line thereof and away from the first side of the baler. The angle A is preferably 20 degrees. The front edges of the packer fingers 55 are at an angle B (Fig. 4) of at least 90 degrees to a lateral wall 14b of the baling passage which the fingers 55 overlap in their movement. Jamming of material against the wall 14b is thus prevented. The fingers 55 are integral with a vertical rod 56 which is pivotally mounted in the flanges of two gear-wheels (58, 59), Fig. 2 (not shown). Extensions of the fingers 55 are connected to a pitman 68 pivoted at 69 to a part of the frame. When the gearwheels (58, 59) are rotated, the tips of the fingers 55 trace out a path 71. The bottom (14c) of the passage 14 is lower than the bottom of a platform 23, and a plate 73 can be pivoted about a horizontal pivot 74 to control the heightwise distribution of material.

Title: Vehicle acceleration monitoring apparatus
IPC: G01P15/135
Filed: 1970-11-16
Abstract: 1363080 Monitoring vehicle acceleration A J ECCLES and A D MANT 9 Nov 1971 [16 Nov 1970] 54463/70 Headings G1K and G1N [Also in Division H1] Vehicle acceleration monitoring apparatus comprises a accelerometer responsive to vehicle acceleration in a horizontal plane; signalling means actuated by the accelerometer when and only when the vehicle acceleration reaches or exceeds a level, which level is dependent on and varied with the speed of the vehicle; and vehicle speed sensing means whereby the level is varied. The accelerometer preferably is a damped pendulum 17, and upon the occurence of excess acceleration arm 7A contacts a plate 2 and completes a circuit between terminals C and D to operate the signalling means, e.g. a lamp 110 or counter 111 connected to a pulse generating circuit 108, 114-116. Alternatively a buzzer or chart recorder could be used. If the pulse-generating circuit is replaced by a clockwork motor driving the counter, the apparatus can be made entirely mechanical. The centre of plate 2 is cut-out see Fig. 3 so that the level of acceleration at which contact is made is dependent on the direction of the acceleration. The accelerometer is immersed in oil in a reservoir 20 having a flexible forwardfacing diaphragm 21. Vehicle speed is sensed by the ram-effect which deflects the diaphragm inwardly forcing oil through passage 19 into the compartment B and pushing a housing 3 in which the plate 2 is mounted upwardly against the force of spring 16 thus altering the set level of acceleration. If a limit rate return valve is  provided in passage 19, the apparatus will have a memory for high acceleration manoeuvres. The speed of the vehicle could alternatively be derived from the rotation of an axle or the propeller shaft, from a speedometer or atachometer, from the alternator, from the flow of coolant in the vehicle engine, or from the fluidpressure servo-brake, servo-steering or gear change system. If an electrical measurement of speed is used, a profiled contact (33) moved by a solenoid (30) can be provided instead of the hydraulically-operated plate 2, for example as in Fig. 5 (not shown). By providing a second cut-out plate (40) overlying but insulated from plate 2 as in Figs. 6 and 7 (not shown), plate (40) being spring mounted and having a smaller cut-out than plate 2, two levels of excessive acceleration can be monitored, the plates acting as parallel-connected contacts so that the higher level is weighted more heavily than the lower level when a count of 'penalties' representing excessive acceleration is made on the counter 111. In an alternative embodiment Figs. 8 and 9 (not shown) two pendulums (52) are attached to the wipers (53) of potentiometers and are adapted to swing in planes at right angles to one another. The voltage outputs of the potentiometers thus are proportional to the acceleration of the vehicle. The outputs are fed to a gate (56) controlled by a voltage derived from the vehicle speed. The potentiometers may be replaced by strain gauges.
