IPC: E02D3/00
Filed: 1973-07-30
Abstract: 1402687 Wells and mines E M JOSEPHSON 30 July 1973 36267/73 Heading E1F Spaces formed below the earth's surface by the production of hydrocarbons or by the removal of other materials either by mining or by natural processes are filled with liquid at a pressure to give support to the overlying structure not less than that given by the removed material, the pressure being maintained. During production of hydrocarbons the liquid is supplied continuously and simultaneously with the production, the production being increased and the liquid supply being at a deeper level than the removal of hydrocarbons. The liquid may be portable water which by raising the water table restores the fertility of the overlying soil. The liquid may be water containing micro organisms which originally formed the hydrocarbons, or water containing organic matter which feeds the micro organisms, or salt water containing plankton. The liquid may contain substances which sediment to form a porous ionic filter to separate salts from the liquid. The liquid may be continuously monitored and replaced automatically.

Title: Improvements in or relating to condenser chamber dosimeters
Inventor: ABSON WILFRED
IPC: H01J47/04
Filed: 1959-10-26
Abstract: 909,719. Electrostatic measuring instruments. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 18, 1960 [Oct. 26, 1959], No. 36285/59. Class 37. [Also in Group XX] A condenser chamber dosimeter comprises a casing constituting one electrode, and two further electrodes insulatedly mounted coaxially therein, two of the three electrodes being spaced apart to provide between them the sensitive volume. In Fig. 1, the outer casing 1 forms one electrode, and the two inner electrodes 4, 5 are mounted coaxially within it on insulators 2, 3. Insulator 2 also has moulded integrally with it two foils wound to form a condenser 8 which acts as a capacitance between electrodes 1 and 4, this capacitance being large compared with that between electrodes 4 and 5. In operation, electrode 4 is charged to a suitable polarizing voltage with respect to electrodes 1 and 5, which are momentarily connected together during this charging process. When the chamber is irradiated thereafter, a charge flows between electrodes 4 and 5, so that a potential difference develops between electrodes 5 and 1. This is directly proportional to the irradiation dose, and is measured directly on an electrometer. To reduce the sensitivity, a similar condenser may be incorporated in insulator 3, and by suitable choice of these capacitances, the roles of electrodes 4 and 5 may be reversed. In the modification of Fig. 2, electrode 4<SP>1</SP> is not adjacent to electrode 1<SP>1</SP>, but spaced therefrom, the sensitive volume now being the space between them, instead of that between electrodes 4 and 5 as in Fig. 1. In Fig. 1, contact to electrodes 4 and 5 is made through removable plugs 6, 7, but in Fig. 2, it is made through spring-loaded plungers 11, 12 sliding in insulating plugs 13, 14 so that no dirt can enter the device.

Abstract: 980, 738. Automatic voltage regulators. MARCONI CO. Ltd. Aug. 20,1963 [Sept. 26, 1962], No. 36551/62. Heading G3R. A voltage regulator comprises a negative input terminal 1 connected to a tap 6 on a step-up auto transformer 4, 5 and over a diode 9, a terminal 8 and a choke 14 to an output terminal 11, a positive input terminal 2 connected directly to an output terminal 12, a series circuit connecting terminals 8, 2 and including a diode 7, the transformer 4, 5 and a switch 3 such as a transistor or silicon controlled rectifier, and a comparator 15 which compares the output voltage with a reference voltage and which controls the mark/space output waveform of a multi-vibrator 16, this output being applied to vary the operation of switch 3 to maintain the output voltage constant. In operation, when switch 3 closes, the diode 7 conducts making the potential at terminal 8 more negative than at terminal 1 by an amount dependent on the secondary voltage of the transformer. The choke 14 then conducts increasingly and stores energy so that when switch 3 opens, the diode 9 conducts and the current in choke 14 reduces. The stabilized output voltage at terminals 11 and 12 will thus exceed the input voltage, and will be the average potential between terminals 8 and 2.

Title: Improvements in or relating to Communication Systems
Inventor: TIILLOTSON LEROY CONRAD
IPC: H01Q25/00
Filed: 1967-08-10
Abstract: 1,182,629. Aerials; automatic exchange systems; radio signalling. WESTERN ELECTRIC CO. Inc. 10 Aug., 1967 [25 Aug., 1966], No. 36780/67. Headings H4A, H4K and H4L. A synchronous communications satellite 14, Fig. 1, for co-operation with a plurality of spaced-apart ground stations 11, 12, 13 comprises an aerial having a reflector 15 with a concave surface and a plurality of individual feeds 17, 18, 19 each of which is positioned at a point on the focal surface of the reflector where an image of a respective ground station is formed. Simultaneous communication between the ground stations using the same frequency is thereby made possible. As described with reference to a synchronous satellite in which the attitude and the pointing of the aerial are stabilized by known means, said satellite contains a diplexer (20), Fig. 2 (not shown), for each feed, to which are connected a transmitter (21) and a receiver (22). The inputs to the transmitters and the outputs from the receivers, which may be at an intermediate frequency, are connected to a network (23) comprising suitable filters and switches under control by signals received from the ground by a receiver (24) having an auxiliary aerial (25). The function of the network (23) is to connect any one (or more) of the receivers (22) with any one (or more) of the transmitters (21), as may be required. By including filters of the channel dropping type in the network (23), the output from a receiver may be separated into sub-bands which may be connected to different transmitters. If required, particular receivers and transmitters may be permanently wired together inside the network (23). In an embodiment, a cylindrical satellite body 31, Fig. 3, contains a concave reflector 30 of part-spherical shape which co-operates with a tilted plane reflector 32 to receive and transmit radio waves through an aperture 34, which is fitted with a cover transparent to those waves. Multiple feeds 35 project through an aperture 36 in the reflector 32 and terminate in horns 37 distributed on or near the focal surface of the reflector 30. Each horn 37 may be of pyramidal type having a square cross-section with excitation by an electric field directed along a diagonal thereof, in order to reduce side lobes. The invention may also be applied to satellites in which there is a reflector formed as a segment of a circular cylinder.

Title: Improvements in or relating to automatic winding machines
IPC: B65H54/24
Filed: 1962-09-28
Abstract: 987,480. Positive clutches. ABBOTT MACHINE CO. Inc. Sept. 28, 1962 [Sept. 29, 1961], No. 36866/62. Heading F2C. [Also in Division D1] This Specification describes an automatic winding machine (see Division D1) utilizing three clutches that are generally similar, two of which act as single revolution clutches and one of which acts as a means for skipping one-half a revolution. In Fig. 4 such a clutch, intended to rotate in the direction indicated, has a pawl carrying element 245 having pivoted thereon alternate tail-less and long-tailed pawls 246, 247 and 248, 249, the long-tailed pawls having their tails in the trailing direction of the rotary movement of the clutch. The pawls are urged inwardly by spring wires 250 and 251 and the tail-less pawls are to prevent overrunning. In the case of the single revolution clutches a pin carrier element 255 carries a single pin 256 adapted to be engaged by the leading face of either long-tailed pawl 246, 247 and to be driven thereby. By moving a stop element 258 into the path of movement of the long tails the rotation of the pin 256 will stop when it reaches the setting in which the stop element 258 is struck by the long tails, the long-tailed pawls at this setting being continually rocked away from the pin 256. If the stop element 258 is subsequently removed for a period just long enough to allow a pawl to engage the pin 256, the pin carrier will be driven through one revolution. In the case of the clutch for skipping one-half of a revolution a second pin 256a is added. With the stop element 258 normally removed from the pawl path, and with a second stop element 258a permanently positioned to trip a pawl at approximately 180 degrees from the position at which a pawl can be tripped by the movable stop 258, such a clutch will normally drive continuously but if the movable stop member is operated to trip just one long-tailed pawl while the other long-tailed pawl is in tripped position in passing the permanent stop 258a the pin carrier 255 will skip one-half revolution.
