Title: Improvements relating to collars for wear
IPC: A41B3/06
Filed: 1959-12-22
Abstract: 964,318. Collars for personal wear. B. LIGHT. Nov. 17, 1960 [Dec. 22, 1959], No. 43507/59. Heading A3V. A collar interlining has fabric sections secured adjacent the ends of the cape portion and formed with spaced slits in which are threaded flexible stiffening strips. As shown a section 1 of preshrunk textile fabric coated on one side with polythene has spaced slots 13 or pairs of slots (not shown) through which a flexible stiffening strip 15 is threaded. Alternative forms of strip are shown. Fabric reinforcements 71 coated on one side with polythene are spot welded to the cape portion 45 of an interlining 41 and the sections 1 are spot welded to the reinforcements with their edges 5 and 11 aligned with the edge 75 of the reinforcements and the edge 81 of the interlining respectively. The interlining 41 of which the neck band portion has one side coated with polythene is then stitched to both plies of the collar and the collar is turned. A line of top stitching passes through the tip 17 of the stiffener 15 and the sections 1. The collar is then pressed in a fusing press to fuse the reinforcements 71 to the interlining, the sections 1 to the reinforcements and the neck band portion 43 of the interlining to the collar. The strip 15 if formed of thermoplastic material is simultaneously banded to the adjacent layers. In an alternative method, omitting the spot welding, the fusion is carried out before the interlining is attached to the collar. The polythene coatings may be omitted when threads, e.g. celluloseacetate, fusible under heat and pressure or when treated with a solvent, are incorporated in the reinforcement 71 and sections 1.

Title: Autopolarization of electrostrictive transducers
Inventor: RICH STANLEY R
IPC: H01L41/04
Filed: 1959-12-22
Abstract: 879,824. Electrostatic machines; voltage multipliers. GENERAL ULTRASONICS CO. Dec. 22, 1959, No. 43525/59. Classes 35 and 38 (2). A D.C. biasing voltage to maintain prepolarization of an electrostrictive vibrator is derived from the A.C. energizing supply, and is proportional to it. As shown in Fig. 1, an A.C. source 10 charges the electrodes 13, 14 of an electrostrictive transducer 11, e.g. of barium titanate, in the same sense (determined by a rectifier 15) as the transducer's remanent polarization. In this arrangement the charge is at substantially the peak voltage of the source, as it is in a modification (Fig. 4, not shown), but a voltage doubler circuit, Fig. 5, or a cascade arrangement which quadruples the peak voltage (Fig. 6, not shown) may be employed. The biasing voltage causes the transducer to operate at a favourable part of its " hysteresis " loop, where losses are small and above the point of remanence.

The treatment is normally carried out between 1 and 100 seconds between 20 and 60‹C (for alcohols) or at 23‹C (for acetonitrile). The material may subsequently be treated with water for 1 to 100 seconds between 20‹ and 90‹C before exposure to further increase the speed. Preferred vesicular materials are those containing as binders either (a) acrylonitrile/hydroxyalkoxy acrylate copolymers or (b) epoxy polymers (Specification 1330344) and preferably containing fluorocarbon or silicose surfactants (as disclosed in Specification 1352560 and 1352559 respectively).

Title: Ascorbic acid esters and a process for the manufacture thereof
IPC: A23K30/00
Filed: 1963-11-08
Abstract: The invention comprises 6-(O-alkenoyl) derivatives of ascorbic acid wherein the alkenoyl group is derived from an olefinically unsaturated fatty acid containing 8 to 20 carbon atoms.  The compounds are obtained by esterifying ascorbic acid with the unsaturated fatty acid in the presence of boron trifluoride.  In examples, esters are prepared from ascorbic acid and isoascorbic acid with oleic acid.  Other fatty acids mentioned are elaidic acid, linoleic acid, linolenic acid and arachidonic acid.ALSO:Fats and vegetable oils are stabilized by adding an ester of ascorbic acid with an unsaturated fatty acid containing 8 to 20 carbon atoms.  The ester may be mixed with an edible carrier e.g. a partial glyceride, and added to the fat or vegetable oil.  In an example 6-(O-oleoyl)-ascorbic acid is mixed with L-proline, gamma tocopherol and glycerine monooleate and added to sunflower oil and lard.ALSO:Foodstuffs and animal feeds are stabilized by adding an ester of ascorbic acid with an unsaturated fatty acid containing 8 to 20 carbon atoms.  An example of the ester is 6-(0-oleoyl)-ascorbic acid.  Foodstuffs mentioned are milk, sausages, salad cream and potato powder.

Abstract: 1455060 Doppler sonar equipment SPERRY RAND CORP 14 Oct 1974 [25 Oct 1973] 44361/74 Heading G1G Doppler. sonar equipment for use in e.g. marine navigators, 'Janus' speed logs &c., is described, which is substantially similar to that described in U.K. Specification 1392005, but which further comprises detecting means for detecting the envelope of the signal-plus-noise fluctuations of the output voltage produced by the receiver and thresholding means responsive to the output of the detecting means for producing an enabling signal which controls a Doppler gate signal which permits counting of the Doppler zero-crossing signal in an N-period counter, only when the received signal is above the threshold, which is set to provide optimum conditions for discriminating against noise in accordance with criteria derived from a mathematical treatment of the noise error &c. which is given. The invention may also be applied to CW systems, and to systems having one, or three or more channels. In Fig. 1, the signal received from echoes by transducer 15 is fed through tuned limited (at a level above that in threshold comparator 23) amplifier 17, to zero-crossing comparator 19, where an output pulse is generated for zero-crossing of the signal. N-period counter 31 counts these pulses only when enabled by Doppler gate generator 33, which is controlled by threshold comparator 23 via turn on and turn off logic 25, 27. The threshold comparator is adjusted to turn on, on having applied at the positive input thereof a signal from envelope detector 21 greater than the negative input voltage which is adjusted to value for optimum noise reduction. Signal combining and display means (29), Fig. 2 (not shown), measures the time taken for the N-counts of counter 31, omitting any time when during the count the threshold is not exceeded, and subtracts the two channel signals, and displays the ships speed in known manner.

The lens carrier is coupled to the device 2 by a sliding support member 11 which engages the carrier at 17 and which has a pivotally mounted lever 10 biased by a spring 12 into frictional engagement with a roller 9 mounted on the device 2. When the light rays reflected from the slide surface do not fall precisely between the photo-cells the motor drives the lens carrier and hence also device 2 via coupling 9, 11 until the photo-cells are positioned so that the light rays fall therebetween. The carrier and device 2 are uncoupled by energizing electromagnet 19 to attract lever 10 out of engagement with roller 9. The parts may also be uncoupled manually by depressing button 23.

The longitudinal position of the seat may be altered on changing the position of the locking member 5 by moving its carrier slide 4. Slide 4 is released by turning shaft 14 to remove rack 9 from tooth 7. The arms 141, 142 may be replaced by a system of rods and levers, Fig. 8 (not shown). Alternatively (Fig. 12, not shown) a locking member (38) may be atached to a sliding member (35) movable on a rail (36) and locked in position by a finger (42) on a lever (41) engaging holes (44) provided in the upper face of the rail (36).

Patent GB-1589378-A (GB)
Title: Overload couplings
IPC: F16D9/00
Filed: 1977-10-31
Abstract: The coupling has two coupling parts (59, 61), which rotate about a common axis (64). The coupling parts have round flanges (62, 63) which rest against one another. The two coupling parts (59, 61) are connected to one another for drive purposes by elements with a predetermined breaking point in the form of shear pins (60). A shear pin (60) passes through a hole (60B) in the first flange (63) and projects into a recess (68) in the second flange (62). The other end of the shear pins projects into a sleeve-like holder (65) which contains a preloaded helical spring (67) which presses on the shear pin (60). A sheared-off part of a shear pin is thrown out through a radial channel (69). When the speed of rotation falls, the spring (67) presses the shortened shear pin (60) back into the recess (68). The coupling is particularly suitable for installation in the power take-off of an agricultural machine towed and driven by a tractor. After the shear pin has been sheared off due to an overload, the coupling returns automatically to a state of readiness for operation.   <IMAGE>
