Title: Marine seismic cable buoyancy system
IPC: G01V1/38
Filed: 1973-04-18
Abstract: 1421364 Marine seismic cables; regulating buoyancy EXXON PRODUCTION RESEARCH CO 18 April 1973 [18 Sept 1972] 18691/73 Headings B7A and B7M [Also in Divisions H2 and F2] The depth of a marine seismic cable is controlled by buoyancy regulating units located at intervals along the length of the cable and each of which has a chamber into which water is admitted to increase depth or expelled to decrease depth, either under manual control from on board the towing vessel or automatically under control of a pressure comparator. In a preferred construction each unit comprises a sleeve 30 containing a pressure comparator 40, a buoyancy chamber 43 formed by an inner sleeve 81 (Fig. 6) containing a bladder 83, an electric pump 44, a depth and pressure sensor 47 and a bypass valve 49 moved by an electric motor (not shown). Water is pumped into the bladder 83 by the pump via a line 53 and expands the bladder 83 against a confined volume of air or gas, whose pressure exceeds that of the surrounding water at the depth at which the cable is to operate, and is expelled therefrom by this pressure when bypass valve 49 is opened. The pump and valve motors are controlled in an electrical circuit (see Division H2) which includes manual switches on board the towing vessel which are operated in accordance to readings from the pressure sensor 47 and further switches in the pressure comparator for automatic operation. The comparator 40 comprises a cylindrical housing in which a piston moves due to the inbalance of pressures acting on a diaphragm, one face of the diaphragm being exposed to the air or gas pressure in the buoyancy chamber 43 and the other to a volume of air or gas having a preset pressure. The piston is positioned between the two switelles which respectively actuate the pump or motor. Steel cables 35, 36 pass through the unit and are connectable to similar cables in adjacent sections of the seismic cable. In alternative constructions, the air or gas in the buoyancy chamber 43 may be at a pressure less than hydrostatic and water be introduced into the bladder by opening a by pass valve and expelled therefrom by a pump, and the bladder may be replaced by a low friction piston. Alternatively water may be admitted and expelled by the pump.

Title: Improvements relating to coin controlled telephone apparatus
IPC: H04M17/02
Filed: 1934-06-25
Abstract: 423,560. Automatic exchange systems; telephone sets. TELEPHON-APPARATFABRIK E. ZWIETUSCH & CO., GES., Charlottenburg, Berlin. June 25, 1934, No. 18712. Convention date, June 24, 1933. [Class 40 (iv)] [See also Group XVIII] After a call is obtained by removal of the hand microphone set from a cradle 1, Fig. 1, and dialling, a coin is inserted and moved to a cash-box 45 by a slider 34, the coin 40 being inserted through a slot 42, Fig. 3, to a recess in the slider which is moved by a knob 28 to carry the coin over a plate 39 separating two superposed shoots 33, 32. The coin drops through an end slot in the plate 39 to the shoot 32 and is moved by a pin 43 on the slider to a slot 44 in the top of the cash-box, when the slider is returned by a spring 35. Durings its passage along the shoot 32, the coin engages a pin 31 on a catch 27 which it rocks to release a slide 21. This is moved to the right by a spring 24 and closes contacts mk, Figs. 1 and 4, permitting speech to take place. When the slider 34 is displaced, switch contacts h, normally held closed by a pin 36 on the slider, open. The plate 39 has a depression 47 which facilitates the removal of a coin, should the call be abandoned. The coin shoot system comprising the shoots, slider 34, knob 28 and catch 27 is assembled as a unit and mounted on a cover plate 41 which is secured to the instrument base 3 by bolts. The cradle 1 is raised by the piston 6 of a spring dash pot 4, 5 acting through a roller 7 on a lever 8 pivoted at 10. The lever 8 is connected to a bell-crank lever 9 by a rod 12 surrounded by a spring 13 and passing through a bent end 17 of the lever 9, one end of the rod being forked to engage a pin 14 on the lever 8. Through this connection, movement of the lever 8 causes the lever 9 to move with a snap action. One end of the lever 9 acts on a lug 18 on the dial 19 to restore dial auxiliary contacts O, dk, and the end 17 closes contacts HU, vk. The operation of these contacts is delayed by the dash pot 4, 5 to prevent fraudulent operation by manipulation of the receiver rest. When the microphone set is replaced, the contacts HU, vk are opened with snap action and a roller 11 on the lever 8 engages a bent up end of the slide 21 to return this to the position where it is again held by the catch 27 and the contacts mk are open. SK are contacts operated by a key to enable calls involving more than a local fee to be made.

Abstract: 319,820. Seifer, T. June 28, 1928. Liquid inducers; cleaning.-In cracking or distilling oils by contact with molten metal or melts, circulation of the melt between a reaction chamber 3 and a chamber 1 in which the melt is heated is obtained by the injector action of the oil itself which is projected into the melt through a pipe 7 and injector nozzles 2. The circulation may be augmented by the additional action of a pressure medium, e.g. a gas, admitted through a pipe 6. In the modification shown in Fig. 6, the heating and reaction chambers are concentric and are separated by a cylinder 14. The nozzles 2 are U-shaped. The injector nozzle, Fig. 9, comprises a pointed, feed needle 17 having an axial bore 18 leading to branches 19 which extend to the end of the needle and unite on its outer surface. The needle is mounted in a hollow cylinder 21 which is mounted in a cylinder 26 screwed into a recess in the wall 31 of the reaction chamber.

Title: New benzene suplhonamide derivatives and a process for their manufacture
IPC: C07D239/69
Filed: 1960-05-27
Abstract: The invention comprises 2-sulphanilamido-5-alkoxy (e.g. methoxy- or ethoxy)-pyrimidines and their preparation by reacting an acylsulphanilic halide with a 2-amino-5-alkoxy-pyrimidine, followed by hydrolysis of the acyl group. Alternatively it is proposed to prepare the sulphonamide compounds by the reaction of other p-substituted benzenesulphonic, sulphinic or sulphenic acid derivatives with a 2-amino-5-alkoxy-pyrimidine, followed by oxidation if necessary; reaction of a benzenesulphon-sulphen- or sulphinamide with a 2-halo-5-alkoxy-pyrimidine; reaction of a benzenesulphonamide salt with a 5-alkoxy-pyrimidine-2-trimethylammonium salt; or ring closing reaction of a benzenesulphonyl guanidine with b -dicarbonyl compounds.  2-Amino-5-methoxy-pyrimidine and 2-amino-5-ethoxy-pyrimidine used as starting materials are made by reacting the alkoxymalonic ester with guanidine carbonate, treating the resulting alkoxy-malonyl guanidine with phosphorus oxychloride and dehalogenating the resulting 2-amino-5-alkoxy-4, 6-dichloropyrimidine.

Title: Improvements in or connected with stereoscopic observation instruments such as stereoscopic rangefinders
IPC: G01C3/14
Filed: 1936-07-09
Abstract: 468,481. Range - finders &c. BARR & STROUD, Ltd., and FRENCH, J. W. July 9, 1936, No. 19011. [Class 97 (i)] A stereoscopic observation instrument, particularly a range-finder, comprises an imageforming optical system having in the plane of triangulation a magnification of the order usual in such instruments, while in the vertical direction the magnification is reduced to as small a magnitude as will enable the object to be properly observed so as to facilitate the fusion of images the vertical adjustment of which may be defective. The vertical magnification may be approximately unity. Figs. 4 and 5 show a system comprising simply an objective A and eyepiece B each having different powers in horizontal and vertical planes. In the horizontal plane, Fig. 4, the image plane of the objective is at D, whereas in the vertical plane, Fig. 5, the image is at D<1>. The horizontal and vertical powers of the eyepiece are such that it presents both images D, D<1> to the eye C, the horizontal and vertical magnifications of the telescope then being AD /DB and AD<1> D<1>B respectively. In Figs. 6 and 7 the objective A and eyepiece B have again different powers in horizontal and vertical planes, and a field lens E between them has power in the vertical plane only. In another form using a field lens, this lens may have such different horizontal and vertical powers as to enable an objective to be used having equal powers in horizontal and vertical planes, i.e. the objective may have spherical surfaces. In Figs. 12 and 13, the objective comprises two widely separated parts A<1>, A<2> each having different horizontal and vertical powers. The focal planes may in this case be made to coincide so that an eyepiece with spherical surfaces can be used. The optical parts, such as the objective, eyepiece, or reflecting prisms of a rangefinder, may be reduced in height so as to be of substantially less size than would be necessary for a corresponding instrument with uniform magnification. Specification 325,956, [Class 97 (i)], is referred to.

Title: Improvements in the operation of the cell switch of a storage battery
IPC: H02J7/02
Filed: 1953-07-09
Abstract: 726,283. Systems for charging batteries; standby supply systems. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. July 9, 1953 [July 14, 1952], No. 19040/53. Class 38 (4). A standby supply system for a D.C. load 5, such as a telephone exchange, normally supplied from A.C. mains 2 through a variable voltage rectifier 1, includes a battery having a main section 6, which normally floats on the rectifier, and an " end-cell " section 7 which, upon failure of the mains source, is automatically connected in series with the section 6 by a switch 8 under the control of a relay 23 responsive to load voltage. Upon restoration of the mains supply, the two sections remain in series across the load circuit for charging by the rectifier, the switch 8 reverting to its normal position only when the battery has been fully recharged. To this end, the sensitivity of relay 23 is made dependent on the position of switch 8 by an auxiliary contact 27 thereof controlling the inclusion, or otherwise, of a resistor 25 in the energizing circuit of the relay. If the load circuit includes apparatus intolerant of the circuit voltage rise consequent upon recharging of the battery at full rate, a contact 13 remains closed whilst such apparatus is connected to the circuit, thereby energizing a relay 14 which, through a further relay 16 maintains open (at contact 28) the energizing circuit of relay 23 and (at contact 19) short-circuits a resistance 20 in the regulating circuit of the rectifier, whereby the output voltage of the rectifier is caused to assume a value such that normal load voltage obtains. Opening of contact 13 upon disconnection of the voltage-sensitive portion of the load removes the short-circuit on the voltage-control resistor 20 and the rectifier voltage increases to the value necessary for fully charging the battery. When the fully charged voltage is reached, relay 23 responds and so returns switch 8 to its initial position in which the battery section 7 is cut-out and in which auxiliary contact 22 of the switch shortcircuits regulator-resistors 20, 21 to restore normal rectifier voltage. Relay 16 is also controlled by a charging current relay 4 which causes closure of contact 28 when the current has decreased to a certain value and so completes the energizing circuit for relay 23.
