Abstract: 1483829 Headphones; reverberation devices AKG AKUSTISCHE U KINO-GERATE GmbH 11 Sept 1975 [16 Sept 1974 19 Nov 1974 29 Nov 1974 24 April 1975 2 May 1975] 37500/75 Headings H4J and H4R An earpiece for a headphone includes one or more passive diaphragms positioned in respective apertures which couple the air chamber formed between an active electro-acoustical transducer and the ear inlet with a sound path which extends to the atmosphere, to the rear of the active transducer diaphragm or to an acoustically active cavity. Nineteen different embodiments are described with respect to the 31 Figs., the aim being to produce a suitable frequency curve for the earphones. The active transducers may be of the moving coil, electrostatic, electret or piezoelectric type. Each passive diaphragm may have an associated acoustic resistance positioned adjacent thereto. Figs. 1-15 of which only Figs. 4, 5 are shown refer to arrangements in which the air chamber 4 is linked to the air space to the rear of the active diaphragm 1. The arrangement of Figs. 4 and 5 particularly show a plurality of passive diaphragms 5 placed symmetrically around the active diaphragm 1. Alternatively a single annular passive diaphragm 14 may be used. Such an annular passive diaphragm may be integrally formed with the active diaphragm, using paper for the passive section and a plastics film for the active section. Alternatively the whole composite diaphragm may be made of plastics film. Figs. 10-15 (not shown) illustrate similar arrangements applied to quadraphonic headphones. Figs. 16-20 of which only Fig. 19 is shown concern arrangements where the active transducer 124 is coupled via sound tubes 122 to one or more ear pieces which include passive diaphragms 128 in apertures which extend via an acoustic resistance 129 to the atmosphere, Fig. 19, showing monoaural headphones. Figs. 21-29 of which only Figs. 25, 26 are shown illustrate various embodiments of earphones in which passive diaphragms are placed in air passages extending to the atmosphere and/or acoustic cavities. In the embodiment of Figs. 25, 26 means 240, 241 are provided for adjusting the size of the apertures extending to the atmosphere, e.g. to effect tone control. Figs. 30 and 31 show two arrangements for producing reverberation effects so as to remove the "in the head" sensation obtained with stereo headphones. In Fig. 30, some of the passive diaphragms are coupled by springs whereas the same effects can be obtained by using specially shaped passive diaphragms as shown in Fig. 31.

Title: Improvements in or relating to the covering of wires with fibre threads
Inventor: DAVID PETER
IPC: H01B13/08
Filed: 1962-10-04
Abstract: 1,016,608. Winding threads on to wire. VILLAMOSIPARI KUTATO INTEZET. Oct. 4, 1962, No. 37622/62. Heading B8G. A method of winding threads around a wire comprises moving the wire axially and causing the threads to run with a rotary motion about the wire in a common direction, the threads being crossed and twisted over each other in pairs at least once during each revolution about the wire. In Fig. 3 the wire 11 is moved continually in the direction of the arrow 15 whilst the threads 12, 14 are wound thereon. The winding is performed by two thread guides 16, 17 such that whilst guide 16 moves along the circle 1 between the points 33 and 23, the thread guide 12 moves along the circle II between the points 34 and 24. Thereafter the shaft 18 is turned through 180 degrees to cross the threads 12 and 14 over and the thread guide 17 now moves along the circle 1 between the points 27 and 31 and the thread guide 16 now moves along the circle II between the points 26 and 32. Thereafter the shaft 18 is turned through a further 180 degrees and the operation is repeated. In Fig. 4 (not shown) the wire 11 again moves continually in the direction of the arrow 15 whilst the threads 12 and 14 are wound thereon. The winding is performed by two diametrically opposed thread guides 16, 17 that rotate in a common circle II. Initially the thread guide 16 moves from point 26 to point 32 and thread guide 17 moves from point 34 to point 24. Thereafter the diametrically opposed thread guides 16, 17 are displaced along the axis of the wire 11 to a setting in which they rotate in a circle I where the thread guide 16 moves from point 33 to point 23 and thread guide 17 moves from point 27 to point 31. The thread guides 16, 17 are then moved back to the location of the circle II and the process is repeated. Each movement of the thread guides 16, 17 along the axis of the wire 11 causes the threads 12, 14 to cross.

Abstract: 941,650. Lathes. BROWN & SHARPE MANUFACTURING CO. Oct. 8, 1962 [Aug. 28, 1962], No. 38064/62. Heading B3T. [Also in Division F2] A change speed gear driving a machine tool spindle through alternately clutchable first and second spindle driving elements has a first pair of pick-off gears driven from the input shaft comprising a first transmission line and a second pair of pick-off gears driven from the first pair of gears to comprise a second transmission line, clutch means selectively connecting the first and second transmission lines to the first spindle driving element, a third pair of pick-off gears driven from the first or second pair of gears and connected to the second spindle driving element. An electric motor 20 drives a shaft 44 through a chain 34 and a first pair of pick-off gears 40, 42, the shaft having a gear 50 driving a gear 52 rigid with a clutch member 54 and, through a second pair of pick-off gears 56, 58, a shaft 48 on which is mounted a sleeve 46 carrying a sprocket 22. The sprocket 22 drives a first spindle driving element 14 through a chain 24, the element 14 being clutchable by a double clutch 18 to the tool spindle 12. Engagement of the electromagnetic friction clutches 54 or 62 respectively drives the element 14 through the first and the first and second pairs of pick-off gears. A gear 64 on the sleeve 46 drives two oppositely rotating shafts 68, 70 either of which may be connected to a shaft 72, driving the second spindle element 16 from a sprocket 26, by a third pair of pick-off gears 76, 78: the shafts 68, 70 providing reverse spindle rotation if desired. The spindle may thus be driven at four speeds each determined by the ratios of the three pairs of pick-off gears. The double clutch 18 is operated by a cam 80 from the rear drive shaft 82 of the machine, the shaft 82 being driven by a part revolution clutch from the front cam shaft 92 which rotates through one revolution for each machine cycle and carries a cam 116 operating a spindle speed switch 114. The switch 114 controls a relay CR1 having contacts CR1, and CRE12 for the electromagnets 99, 97 of the clutches 62, 54 respectively, the clutches being engaged alternately by alternate movements of the switch 114. During a working cycle of the machine the clutches 62 54 and 14, 16 are engaged in combination to provide four spindle speeds. In a modification, the shaft 68 is driven from a gear rigid with the gear 52 to provide three forward or two forward and one reverse spindle speeds. Specification 442,820 is referred to.

Abstract: 1,079,360. Electrophysical measurement. GENERAL ELECTRIC CO. Sept. 7, 1965 [Oct. 23, 1964], No. 38134/65. Heading G1N. In a leak detector of the type in which the atmosphere outside the enclosed vessel is sampled for the presence of halogen tracer gas by drawing the air through an ionisation detector 10, the voltage drop across resistor 14 due to ion current is added to a bias voltage tapped off a potential divider 17 so as to cause conduction of a cold cathode thyratron 24 which in turn energizes a neon indicator lamp (not shown) from an A. C. source 28. The firing point of the thyratron 24 is stabilized by illuminating it with a neon lamp 32. A capacitor 21 between control electrode and cathode of the thyratron causes the circuit to act as a relaxation oscillator, the frequency of which is proportional to the amount of tracer gas present. An additional capacitor 36 is also provided to change the time constant of the oscillator to extend the range of indication.

Title: Threaded fastener tightening apparatus having at least two stages
IPC: B23P19/06
Filed: 1975-09-19
Abstract: 1528319 Automatic control STANDARD PRESSED STEEL CO 19 Sept 1975 [19 Sept 1974] 38496/75 Heading G3N [Also in Division B3] A fastener tightening apparatus for tightening a plurality of fasteners in at least two stages comprises a plurality of power operated wrenches, each including driving means providing a rotational output which will be discontinued when an initial predetermined condition thereof has been reached, means in each wrench providing signals representative of the rotational output of that wrench and a control circuit responsive to the signals for providing an output when it receives no signals, means for restarting the rotational output of the wrenches when said output of the control circuit is produced, and means for shutting-off each wrench at a final predetermined condition. In the apparatus shown, each of motors 14 is connected via a two-speed/torque gear arrangement to output shaft 16, the high speed low torque output being changed to low speed high torque output by a fluid-pressure signal. At the initial predetermined torque the motor, running-up the fastener at high speed, stalls and signals from a proximity detector 28 which detects rotation of toothed encoder device 30 in terms of pulses then cease and a NAND gate 40, which operates when the signals from all the detectors 28 cease, sends a signal to AND gate 48 or may send a signal directly to solenoid valve 21, which controls the flow of fluid to the gear arrangement which changes gear. Meanwhile, signals from a strain gauge or torque cell 25 on each wrench may be continuously fed in a checking circuit to a comparator 42, where the actual torque signal is compared with an artificial torque signal from generator 44 indicating a "presnug" torque, i.e. a torque less than that needed for tightening of the fastener, and a signal is sent when this torque is exceeded thus indicating that the wrench is actually operating. This signal and those from the other wrenches is fed to AND gate 46 and if all the wrenches are operating a signal passes to AND gate 48 whereupon if all the wrenches have reached the initial predetermined torque solenoid valve is operated as before. Each wrench now operates at a higher torque and in a further control circuit signals from detectors 28 indicating angular rotations and from cells 25 indicating torque are fed to shift register 32 which provides a signal of torque/increment of rotation which is compared at 34 with instantaneous torque to provide a signal of the instantaneous gradient of the torque/rotation curve Fig. 2 (not shown). Maximum values of the gradient are stored at 36 and instantaneous values compared therewith at 38. If the instantaneous valve is less than or equal to 50% the maximum - start of the yield region of the fastener assembly - a signal is sent to valve 20 to shut-off the motor and, after a time delay by timer 52 a signal resets the gearing via valve 21 so that the cycle may start again.

Title: An improved method of manufacturing milk products
IPC: A23C9/123
Filed: 1929-12-16
Abstract: Milk products more particularly for use in baking are obtained by treating skimmed or other milk freed from bacteria by pasteurizing &c., with peptonizing bacteria e.g. b. caucasicus or b. acidophilus, which produce no or little lactic acid, i.e. less than b. bulgaricus, and thereupon converting into dired form. Preferably, before drying, the precipitate obtained is finely divided by treatment in a homogenizer or similar apparatus or with one or more peptizing agents, e.g. alkali metal salts of phosphoric or citric acid, such as disodium orthophosphate, which may be added at the beginning of or during the precipitation.  The small amount of acid formed may be neutralized before drying.  The product may be used to replace 20 per cent. or more of the flour used in baking and may also be employed in the manufacture of biscuits, cakes, chocolates, and pralines &c. in the same manner as milk powder.

Abstract: 1223854 Making timber frames J HURN, C R F KING and D R DEANE 16 Aug 1968 [23 Aug 1967] 38789/67 Heading B5L A method of manufacturing a timber frame comprises assembling parallel head and sole stringers 10, 11 and nailing a stud 1 transversely between them at a datum line X-X, Fig. 8b; moving the stringers logitudinally by a conveying means over a predetermined distance; clamping the stringers after they have been so moved; inserting a second stud 2, Fig. 8f between the stringers on the datum line X-X, clamping the stud 2 in position, and nailing the stringers to the opposite ends of the stud 2. The term "nailing" is defined as including any mechanically equivalent fastening operation, e.g. fastenings made by dowels, staples, woodscrews, pronged plates of corrugated strips. The apparatus described for performing the method comprises two parallel sets of guide rollers 42, Fig.1, carried by channels 27 which are carried by a fixed bed of the machine and are adjustable towards and away from each other by screw means 25, and carriages one on each channel 27 and slidable therealong by rotation of leadscrews. Fluid operated clamps A, C, D, G are fixed to the channels 27 and clamps B, F to the carriages. In operation of the machine the stringers 10, 11 are fed manually along the sets of rollers 42, shown as fences 100 in Figs.8b and 8f, until their ends abut pneumatically actuated stops H. The distance apart of the stringers is adjusted by the screw means 25. The clamps A, C, and D are operated to engage the stringers. A stud 1 is positioned between the stringers on line X-X and clamped in position by clamps E against stops H, Fig.8b. The stud is then secured to the stringers, e.g. by manual or automatic nailing. The clamps B and F are then operated, the clamps AC, D and E released, the stops H lowered and the carriages advanced the desired distance. Clamps ACD are again engaged and clamps B and F disengaged. The carriages are returned to their initial position. The stops H are partly raised, and a second stud 2 is inserted and held in position by clamps E, Fig. 8f position. The stud 2 is then nailed in position and the sequence of operations is repeated until the frame is completed. The operation of the machine may be from a programmed punched or recording tape. Means may be provided at the line X-X for marking the frame for further operations.
