Title: Arrangement for automatically adjusting an electrical characteristic of a circuit
IPC: H03H7/40
Filed: 1977-03-07
Abstract: 1517143 Automatic control THOMSON-CSF 7 March 1977 [9 March 1976] 09573/77 Heading G3N [Also in Division H4] In an arrangement for automatically adjusting an electrical characteristic of a circuit, e.g. the impedance of a tunable filter or a matching circuit for an antenna, optimization of the characteristic is obtained by cyclically exploring different combinations of n reactances, memorizing the combination corresponding to the best adjustment, and switching the reactances to this combination on completion of a cycle. As shown, a matching circuit between a transmitter B and an antenna A has its impedances selectively switched by a binary counter 10, a good match being indicated by a low reflected signal supplied to an amplifier 3 by a directional coupler 1. The output V of amplifier 3 is compared at 4 with the output Vr of a ramp generator 6. As long as Vr < V the voltage Vr remains fixed and counter 10 conducts the cyclic exploration. When V < Vr the ramp voltage Vr is decreased while counter 10 is interrupted until Vr < V again. The combination causing the latest interruption is memorized at 8 and at the end of the cycle is fed to counter 10. The optimal combinations for various frequency bands may be stored in a readonly memory 14 controlled by control circuit 15.

Title: Improvements in cellulose ester compositions and artificial filaments, films, lacquers and other products made therefrom
IPC: D01F1/10
Filed: 1940-06-03
Abstract: 541,660. Cellulose ester compositions. BRITISH CELANESE, Ltd. June 3, 1940, No. 9666. Convention date, June 10, 1939. [Class 2 (ii)] A cellulose ester solution is obtained by using a solvent medium comprising a polymethylene oxide. The solution may be used for the production of artificial filaments, foils, films and like products and also lacquers and plastic compositions. The cellulose ester may be cellulose acetate, formate, propionate, or butyrate. The solvent may comprise dimethylene oxide (ethylene oxide), trimethylene oxide (1:3- propylene oxide), or tetramethylene oxide (1:4-butylene oxide), preferably in conjunction with another solvent. Cellulose acetate or other acetone-soluble cellulose esters may be dissolved in a mixture of acetone and a polymethylene oxide to give solutions of lower viscosity than similar solutions in acetone alone. An addition of a small proportion of water also reduces the viscosity of the solutions. Plasticizers, such as dibutyl tartrate, dimethyl phthalate, diethyl phthalate, and triacetin may be included in solutions of cellulose acetate in a solvent mixture of acetone and tetramethylene oxide. The solutions which are of reduced viscosity may be more readily filtered and they have less tendency to clog the orifices of the spinnerets when being spun into filaments e.g., by a dry spinning method. The filaments obtained are of higher tenacity than those obtained from solutions of cellulose acetate of corresponding concentrations in acetone containing water but no polymethylene oxide.

Title: Improved apparatus for driving and extracting piles, columns and the like
IPC: E02B17/08
Filed: 1954-04-05
Abstract: 786,484. Driving and withdrawing piles. DE LONG CORPORATION April 5, 1954 [April 13, 1953], No. 9895/54. Class 68(2) A pile, column or the like is driven into the ground, or withdrawn therefrom, by a gripping device comprising two gripners which grip and release the pile in alternation, one gripper holding the pile relatively to the means, e.g. a barge. which takes the reaction of the driving or withdrawing force, and the other gripper acting. on release of the holding gripper, to pull the pile either upwardly or downwardly. As shown, a number of gripping- devices are arranged on a barge 11, piles 27 being positioned in the grippers, so that when the barge is correctly positioned, e.g. for well-drilling, the piles are lowered and forced into the ground, the barge being raised above the normal water level. When drilling is complete, the piles 27 are withdrawn and the barge removed. The gripping-device comprises two sets of.gripping shoes 18, 19 associated respectively with an upper and lower encircling ring 13, 14. The shoes 18 are spaced by inclined guides 43 secured to the ring 13, which assist in positioning the piles in the grippers. The ring 14 is secured to the deck of the barge by feet 15 and the ring 13 is movable vertically relatively to the ring 14 by fluid pressure cylinders 29 which are carried by the ring 14. The rings 13, 14 are formed internally with oppositely inclined surfaces 20, 21 spaced by a cylindrical surface 22, and the backs of the shoes 18, 19 are shaped to correspond, so that the shoes are forced into gripping contact with the pile by relative motion in either direction between the rings and the shoes. The shoes are normally withdrawn from contact with the pile by springs 42 on rods 37 which are pivotally connected to the backs of the shoes. The sets of shoes 18, 19 are selectively moved up or down to bring the shoes into gripping engagement with the pile, by fluid-pressure cylinders 32, on the rings 13. 14, the pistons 33 being connected to arms 34 projecting from the tons of the shoes by pin and slot means 35, 34<SP>1</SP>. The rings 13. 14 are separated and brought together to drive or withdraw the pile bv the jacks 29 which are connected to the upper ring 13 bv pivot pins 31. A clamping band 44, tightened or released bv a fluid-pressure means 47, 48 coacts with the shoes 18, 19 to hold the pile in any desired position. The shoes are provided between the gripping teeth with holes leading to the backs of the shoes, so that mud &c. will be forced through the holes and thus prevented from affecting the gripping action of the teeth.

Title: Improved lubricating apparatus and methods of operating the same
IPC: F16N13/16
Filed: 1936-04-03
Abstract: 473,002. Grease guns. TECALEMIT, Ltd. April 3, 1936, No. 9969. Convention date, April 5, 1935. [Class 102 (ii)] In lubricating apparatus in which lubricant is expelled from a cylinder 1 through a nozzle 11 by a piston 3, the outlet is controlled by a cylindrical valve 21, which is opened by pressure on a handle 51 at the opposite end of the cylinder. The valve engages a resilient seating 17, through which it can be drawn when removing the cover 9. The valve is attached to its rod 31 by a loose connection 29, in order to permit self-centring. A cylindrical projection 15 in the cover 9 guides the valve to its seating and also forms a stop for the piston 3. The latter is acted on by air pressure, supplied through a valve 39 and released, when required, by means of a valve 35. The air pressure acting on a piston 47 on the rod 31 tends to close the valve 21. Alternatively, the piston 47 may be acted on by a spring. The piston 3 may also be operated by a spring instead of by compressed air. The gun may be charged through a valve 53, or by removing the cover 9.
Patent HU-T38267-A (HU)
Title: Duplex pump applicable as artificial heart
Inventor: LUNDBAECK STIG
IPC: A61M60/882
Filed: 1985-03-29
Abstract: A double pump adapted for use as an artificial heart includes two ventricle-simulating chambers that are provided with respective inlets and outlets having valves incorporated therein and that are separated by a common partitioning wall structure. The wall structure has sections that are driven away from each other to reduce the volumes of respective ventricle chambers and expel liquid from the chambers through the outlets. The wall structure can also move laterally in response to differences in pressure between the chambers and hence change the volumetric ratio between them. This ensures a balanced action between the two halves of the heart- simulating pump during a systole phase and a diastole phase. The link mechanism is actuated by a cord through a motor, although only in one direction in the pressure phase, and hence the aforementioned changed volumes are readjusted primarily through the pressure exerted by the inflowing fluid. The pump may also include a variable volume atrium-simulating chamber communicating with the inlet to each ventricle-simulating chamber and having volume that is controlled in part by an externally acting gas pressure that varies in accordance with changes in the volumes of the ventricle chambers.
