Title: Improved attenuator circuit for modulated-carrier signal receivers
IPC: H03G3/22
Filed: 1939-03-25
Abstract: 526,725. Wireless receiving circuits. HAZEL TINE CORPORATION. March 25, 1939, No. 9427. Convention date, April 7, 1938. [Class 40 (v)] The amplitude of the input to the amplifier of a modulated signal is controlled by two coupling circuits which produce opposing voltages in the amplifier input, one of the coupling circuits being passive and the other of variable gain. The antenna circuit 10 is coupled by coil 21 to the tuned input circuit 22, 23, of the highfrequency amplifier 12 whose output circuit is coupled over trans former 27, 28, to a superheterodyne receiver with A.V.C. 13 ... 17. The second input coupling circuit consists of valve 24 whose grid is red over condenser 25 from the antenna circuit and whose output 26 produces an opposing voltage in the input circuit of valve 12. The output circuit of valve 12 includes a transformer 31, 32 which feeds an amplifier 29 and diode rectifier 35, 36, transformers 31, 32 and 33, 34 being designed with the aid of resistances 20, 39, to pass all frequencies within the tuning range of circuit 22, 23. The main selectivity of the receiver resides in the circuits following the winding 31 so that desired and undesired signals are included in the input to amplifier 29. The load of diode 35, 36 consists of resistances 37, 38, 39, and the voltage across resistance 38 is applied negatively over filter 40, 41 to reduce the amplification of valve 12 as the signal increases. The voltage across resistance 37 is applied positively through filter 42, 421, to increase the amplification of valve 24 as the signal increases, thereby reducing the signal input to circuit 22, 23. In the absence of signals, the valve 24 is biased to cut-off or to a low value of transconductance by means of battery 43. When the voltage drop across resistance 37 reaches a predetermined value, the diode 44, 45 becomes conductive, effectively earthing the grid of valve 24 through a battery 451 and preventing the reverse coupling through the valve from overbalancing that of the normal coupling, for received signal amplitude of unusually-large amplitude. In a modification, Fig. 2 (not shown) the normal coupling path consists of two coupled tuned circuits, and the auxiliary parallel coupling, of opposed phase, consists of a valve coupling the inputs of the tuned circuits. The amplifier feeding the diode rectifier is fed from the output of the second tuned circuit, and includes two auxiliary diodes, one for the normal A.V.C on the first amplifying valve, and the other for the limiting action in the control-grid circuit of the reverse coupling valve.

Title: Improvements in the Treatment and Production of Hydrocarbons.
Inventor: FORWOOD GEORGE FREDERICK
Filed: 1917-07-03
Abstract: 128,255. Forwood, G. F., and Taplay, J. G. July 3, 1917. Mineral and tar oils, purifying.-Mineral and tar oils are hydrogenated or simultaneously cracked and hydrogenated by passing their vapours, mixed with steam, over carbonaceous spent shale at 450-600‹ C. The operation may be effected at the same time as the distillation of the shale, so that the shale oil produced is both cracked and hydrogenated. The steam is in excess and is preferably superheated. In hydrogenating shale spirit, as much as 4.7 volumes of water to each volume of spirit may be used; in cracking and hydrogenating shale oil, 2 volumes of water may be used. After passing over the spent shalemaintained at 550-600‹ C., the vapours are led to a condenser and thence to a scrubber, where the gases are washed with heavy shale oil. The heavy shale oil is afterwards distilled, and the distillate is added to the spirit obtained in the condenser. In distilling shale, a vertical retort, fed with shale at the top and with steam at the top or lower down, is employed. About 1/3 lb. of water is used for 1 lb. of shale. The shale oil is distilled at the top of the retort at about 400‹ C. and flows downwards with the steam and is cracked and hydrogenated by passage over the spent shale at the bottom of the retort, which is maintained at about 600‹ C.

Title: Improvements in or relating to Anti-slipping Tiles or Treads.
IPC: C04B33/02
Filed: 1919-04-15
Abstract: 126,287. Norton Co., (Assignees of Jeppson, G. N., and Dietz, C. F.). April 29, 1918, [Convention date]. Stone, artificial.-Non-slipping tiles or treads are formed of particles of granular material of a hardness of 9 or more, e.g. fused alumina or silicon carbide, bonded together by a vitrifiable ceramic material, the tile containing coarse grains to prevent slipping, and fine grains to render the body dense and compact. The coarse grain may be of a size to pass through a 36-mesh sieve, and the fine grains a 120-mesh or finer sieve, intermediate grades being also employed to obtain a compact body. A specific example is given of the use of grains of 20, 60, and 180 mesh sizes. The ceramic material may consist of a fusible material composed of feldspar, ball clay, and slip clay. The mixture is wetted and pressed in moulds, and, after drying, the tiles are burnt at a temperature of about 1300‹ C. for about 100 hours to fuse the bond, and slowly cooled. If too porous, the tiles may be impregnated with a filler such as molten shellac or resin, after which the tile may be heated. Reference has been directed by the Comptroller to Specification 12796/02.

Abstract: 851,058. Road-vehicle spring-suspensions. MOULTON DEVELOPMENTS Ltd. June 26, 1958 [March 26, 1957], No. 9855/57. Class 108(2). On each side of the vehicle front and rear wheels actuate respective hydraulic displacer units 1 which are connected to a common hydraulic accumulator 7. Both rear wheels are connected by a torsion rod 10, the pre-load of which is variable by the action of a crank 11 actuatable by an electric motor 13. The latter is controlled by a switch 14 controlled by an electric or hydraulic device 15 sensitive to changes in vehicle height. The device 15 has a time delay to prevent it being affected by the rapid changes in height due to changes in dynamic load. In a modification (Figs. 3-5, not shown), the torsion rod 10 is replaced by a leaf spring, the central anchoring point of which is carried by a crank rotatable by the motor 13. The accumulators 7 are replaced by flexibility of the connecting conduits 8. Specifications 813,259 and 826,687 are referred to.

Abstract: PURPOSE:To enable further stable molding by making heat history and molding cycle of molten resin identical always, by a method wherein a detected backward movement speed of a screw and a preset target value are compared with each other and back pressure of the screw is controlled so that a deviation between both is eliminated. CONSTITUTION:An injection piston 4 is provided with a rack 8 moving unitarily with the injection piston 4 in an axial direction, and a pinion 9 is engaged with the rack 8. A detector 10 of a backward movement speed of a screw, for example, a rotary encoder is connected with the pinion 9. When the injection piston 4 is moved backward at the time of measurement of plasticization, the measured backward movement speed of the screw is detected by the detector 10 of the backward movement speed of the screw. The signal is applied to a relative arithmetic instrument 18 after amplification and compared with the target backward movement speed of the screw. The relative arithmetic instrument 18 applies the signal to a driver 20 in the direction eliminating a deviation obtained by performing operation and comparision in this manner. Then back pressure of an injection cylinder 3 is controlled by actuating a solenoid remote control valve 21. With this construction, the measurement can be completed in a predetermined period of time.

Title: Tracking control circuit of information signal reproducing device
Inventor: ASAYAMA TAKAO
IPC: G11B21/10
Filed: 1983-01-08
Abstract: PURPOSE:To obtain an excellent reproduced signal even if bits have variance in depth by correcting the 1st and the 2nd reference signals by using sampled values which include pieces of information on bit depths of the tracking reference signals stored in sample value storage circuits previously, and performing tracking control on the basis of the corrected signals. CONSTITUTION:A switch SW2 is turned off prior to the play of a disk to allow a reproducing stylus to traverse recording tracks of the 1st and the 2nd tracking reference signals fp1 and fp2, and the sampled values of the reference signals are stored in the 1st and the 2nd sample value storage circuits SM1 and SM2; and the sample values of the reference signals fp1 and fp2 are compared by a comparator COMP with each other to generate a correcting signal of a signal level, which is supplied to a signal level correcting circuit SLC to perform level setting so that the two reference signals fp1 and fp2 are equal in signal level. Therefore, even if bits 2 and 3 forming the reference signals differ in depth, a control signal is generated after the levels of the reference signals are compensated, so the switch SW2 is turned on to put a control system in operation, thus performing the excellent tracking control.
