Abstract: 1,252,588. Magnetic compositions. GENERAL ELECTRIC CO. 5 Nov., 1968 [18 Dec., 1967], No. 52393/68. Heading H1N. [Also in Division C7] A magnet comprises Sb-coated single magnetic domain particles of Fe or Fe-Co alloy in a Pb matrix which contains (per part by wt. of Pb) 0À001-0À04 parts by wt. of Ca or a Snbased alloy, or 0À001-0À02 parts by wt. of Sn. Specified Sn-base alloys are 14À3% Cu, balance Sn; 6À5% Bi, balance Sn, and In or Te-containing alloys. The magnet may be made by electrolytically depositing magnetic particles into a liquid Hg cathode, heat-aging, adding Pb and Sb, followed by the Sn, Ca or Sn alloy, separating the cathode, e.g. by vacuum distillation, and compressing the residue. The mixture of Hg, Pb, Sb-coated particles and additive may be heated to ensure uniform dispersion of the additive, which inhibits dimensional instability and whisker growth in the finished magnet. In an example, the mixture is compressed in presence of a magnetic field to align the magnetic particles, and to reduce the Hg content. Remaining Hg is distilled from the preforms, which are then ground, classified and compressed with a lubricant.

Abstract: 1,257,566. Camera shutters. KOMBINAT VEB PENTACON DRESDEN KAMERA-UND KINOWERKE. March 12, 1969, No. 12972/69. Heading G2A. A camera shutter has a gear-train driven by a force storage means and an escapement wheel 3 and anchor piece 2, the mechanism giving either a delayed action or a long timing action and being provided with a lever 13 for delayed action control and a lever 23 for long timing action, both levers being coupled through intermediate members with the shutter release 19 and both extending into the region of a pin 25 or dog 26 which each participate in the running-off of the gear-train. For delayed action control, a blocking spring 4 is moved out of the plane of the drawing by a sleeve (not shown) mounted on a spindle 24 so that the escapement wheel 3 is liberated to run-off, lever 6 under action of spring 8 is pushed under the spring 4 to maintain the spring 4 in an unblocking position. The pin 25, mounted upon a gear-wheel (not shown) which rotates about spindle 24, entrains lever 13 which pivots in the direction of the arrow. The pivoting movement is transmitted through a pin 18 to a lever 16, and the shutter release plunger is displaced to effect shutter release. The pin 25 also guides lever 6 out of the range of blocking spring 4 which stops the running off of the escapement wheel 3. For the control of long exposure times, the time setting knob of the camera is set to the 'B' position, and a pin is pushed into one of the holes 26 provided on the gear-wheel, each hole corresponding to a predetermined exposure time. The plunger 19 is then depressed in the direction of the arrow to pivot lever 16 in a clockwise direction, lever 23 dropping into a recess 20 of the lever 16 to secure the latter. Pin 18 mounted on lever 16 pivots lever 10 so that its oblique surface 12 moves blocking spring 4 to allow escapement wheel 3 to run off. After a specific time interval, a pin in one of the holes 26 engages lever 23 which is moved in the direction of the arrow to allow lever 16 to return to its initial position and terminate the exposure by movement of plunger 19. In a second embodiment of the invention, Figs. 2-4 (not shown), shutter release plunger (51) operates upon a lever (45) which is pivotted on a lever (42), the two levers being inter-connected by a lever (47) having a pin (48) and slot (49) connection with lever (42), and a spring (50) coupled to lever (42).

Abstract: 1,259,058. Clutch control; friction clutches. TWIN DISC Inc. 15 May, 1970 [2 June, 1969], No. 23651/70. Headings F2C and F2L. In a transmission system for a motor vehicle wherein an engine E drives a change speed gear GB through an hydraulically operated continuously slipping friction clutch C and a torque converter TC, a governor G driven by the turbine of the torque converter automatically regulates a clutch control pressure 56 and thus varies the clutch slip to maintain the torque converter output speed constant. The clutch C may be of the type described in Specification 1,146,236 wherein for a predetermined control pressure 56 the clutch output speed is maintained constant by a valve V which varies the pressure in a clutch engaging servo chamber 8 in response to centrifugal force that opposes the control pressure 56. The servo chamber 8 is continuously supplied with pressure liquid through an orifice 16 and the valve V controls the exhaust from the chamber 8. The control pressure 56 is additionally supplied from the supply line 14 through an orifice 18 and the governor G controls the exhaust of control pressure from the line 56. A control valve 66 permits adjustment of the loading pressure applied to the outer end of the governor valve G and thus variation of the control pressure 56 and torque converter output speed. The variation in the control pressure 56 adjusts the output speed of the clutch C which automatically maintains its output speed proportional to the control pressure 56. The clutch C may alternatively be of the type described in Specification 1,149,573 which automatically maintains the clutch output torque proportional to the control pressure.

Abstract: 1311284 Geldrop forming UNITED KING- DOM ATOMIC ENERGY AUTHORITY 6 April 1970 [9 April 1969] 18297/69 Heading B5A [Also in Divisions C1 and F1] In a process for making particulate spheres by the gel droplet method, the outflow of spheres from the bottom of the column is controlled by connecting the liquid inlet pipe to the sphere outlet pipe, and proportioning the flow of gelling liquid between the two. The drop forming nozzles at the top of the column may be surrounded by a plenum chamber which discharges a curtain of air or inert gas around the drops (Fig. 4, not shown). Alternatively, the surface of the liquid may be covered with an immiscible organic liquid, e.g. decane + decanol. The spheres, on removal from the column, are lifted in the liquid, by means of an ejector pump (Fig. 3, not shown) to a draining conveyer. The drained liquid, and the liquid withdrawn from the top of the column, is recirculated. The spheres then drop into a washing column fed with cold water in the upper part and hot water in the lower part. The removal of spheres, lifting and draining is as in the gelling column (in Fig. 2, not shown, the supply of hot water from pipe 43 in proportioned by valve 42 between inlet pipe 41 and outlet 40 for spheres). The washing column may be replaced by a sprayed screen conveyer.

Abstract: 1321313 Helium speech processor NATIONAL RESEARCH DEVELOPMENT CORP 14 June 1971 [17 June 1970] 29400/70 Heading H4R In a speech processing system, e.g. for rendering helium speech intelligible, segments of speech signal are loaded into a storage device and subsequently removed therefrom at a different rate, the loading and unloading processes operating pitch synchronously during voiced sounds, and almost continuously during unvoiced sounds, so that the larynx periodicity of the original speech is preserved while shifting the significant vocal cavity resonant frequencies. As described the incoming speech after filtering and shaping to restore the spectral energy content level to that occurring in normal speech, from that occurring in speech in a high pressure environment, is converted to digital form, using a full wave rectifier 3 and polarity sampler 7 to provide digitization to 8 bit pcm relative the mean of the speech signal in the A to D converter 5. A peak picker 9 operates on the full wave rectified speech signal to provide a pulse 2�5 Msecs long to gate samples starting at the commencement of each pitch period into the four storage banks 10, the stores being filled in turn with successive pitch period samples of 2�5 Msec length, via the switch 6 which is stepped by the pitch period pulses from 9. The read out of the signals from the stores 10 is at the rate dictated by the pulse generator 16, and at a rate slower than the read in. The commutator switch 11 is stepped at four times the read shift rate so that a stored sample is read out from each bank of the store in turn before the read shift is actuated, and read out from the store currently being filled is inhibited. Normally only one store bank will have any data in it, the others having been emptied on a previous read cycle, but the arrangement allows overlap of two signal sections if the incoming pitch frequency and the length of each pitch period sample are such as to make the beginning of one sample overlap the end of a previous sample on the slow read out. The 8 bit pcm signals from the stores can be converted to analogue form and added, where more than one store has contents read out at the same time, or the adding can be digital with d to a conversion subsequently. The resulting signal is expanded, if compression has been applied before storage, and filtered to provide a signal which is more understandable than the original speech.

Vane 17 pivots about horizontal axis 16 when the vane is out of line with the wind direction and this movement is transmitted to the rudder 21 by link 29, lever 25 pivoted about horizontal axis 28, arm 39 and lever 31. The position of arm 39 along slot 40 being adjustable by releasing a lock nut (38, Fig. 2) and moving handle 34 to a new position. The rudder may be either a main or auxiliary unit and if the latter it can be mounted on the main rudder. The adjustment of velocity ratio can, according to a modification, be effected by variable eccentrics or cranks. Fig. 4 (not shown) illustrates a modification in which pivoting movement of an auxiliary rudder about axis 28, as a consequence of a change in direction of the boat, produces a corresponding correcting movement of the main rudder.
