Abstract: 1,252,010. Making parts of wearing-apparel. G. F. HAWLEY. 7 Nov., 1968 [7 Nov., 1967], No. 52843/68. Heading A3V. [Also in Divisions B8 and D1] In a wearing-apparel assembly plant, garment blanks S1, S2 (e.g. for making trouser pockets) are stacked on work tables B1, B2 and the work tables are moved to means 31-34 for lifting the uppermost blanks from the stacks and feeding them one at a time to a photo-cell controlled conventional lock-stitch sewing machine 71. Each separated blank is adjusted in position by air jets or resilient fingers, to register exactly with stop edges 63 or 68. The blanks are superimposed on one another on stitching conveyor 65, 66 by transfer means; transfer of blank S2 being effected by swinging arm 69. The blanks are held together by guides 72, during sewing. The sewn blanks are stacked on work tables B3 for transfer by means of turn-table 80, to the next stage. To ensure that the work tables reach the appropriate stages in the correct order they may have notches which can be sensed by feelers (89, Fig. 8, not shown) or holes for detection by photo-cell units (89, Fig. 24, not shown) at the input ends of the stages. A second stage operation (Fig. 3, not shown) repeats the first process to attach a third blank S4 on the opposite edge of the blank Sl, by the same procedure as in the first stage operation. After a third stage operation (Fig. 4, not shown), which involves overedge stitching and optional trimming, the pocket is formed in a fourth stage operation (Fig. 5, not shown), by creasing (to turn back the curved bottom edge of blank S1) and folding: the formation being completed by a double line of lock stitching (106, Fig. 27, not shown). There is also disclosed an arrangement (Figs. 8-10, not shown) including tracks (111) of variable inclination, down which work tables run to the blank separating means. The tracks are gradually raised to keep the top of the stack of blanks at the same level during feeding to the registration means. The empty work-tables may be stacked and removed seriatim from the stack (Figs. 11 and 12, not shown). Apparatus is described for separating the uppermost blank from the stack (see Division B8) and for folding and creasing a blank (see Division D1).

Abstract: 1,257,836. Subaqueous transducers. WESTINGHOUSE ELECTRIC CORP. 13 March, 1969 [13 March, 1968], No. 13256/69. Heading H4J.  A pressure compensated transducer for subaqueous use at great depths comprises a piezoelectric transducer element 10 having its side and rear faces spaced by a distance d from an inertia loading mass 12, e.g. of aluminium, lead, brass or gold. A sound-absorbing material 14 such as butyl rubber in which is embedded aluminium powder or flake acts as a pressuretransmitting means. Its specific acoustic impedance approximately equals that of sea water. The distance d is n#/4 where n is an odd number and # is the wavelength of a wave in material 14 at the operating frequency or at a slightly different frequency. Inertia loading masses 20, 21 decouple unwanted radiation in the material 14 from the surrounding sea water. A cover 24 and transducer fluid 26 both have acoustic transmission characteristics similar to that of sea water. Preferably the inertia loading mass 12 is of aluminium one inch thick and the transducer operates at 60 kHz, whereby the impedance of the mass 12 is approximately twenty times that of sea water. In a second arrangement (Fig. 5, not shown) the inertia loading mass is of lead. A second outer inertia loading mass (42) is spaced a distance d<SP>1</SP> from the first, the intervening space being filled with further sound-absorbing material. In a further arrangement (Fig. 8, not shown) a single inertia loading mass is provided, but the intervening space is filled with silicone fluid, the transducer element being resiliently held by corrugated metal between the element and inertia loading mass. A disc-shaped transducer element is also envisaged. In all embodiments the transducers are operative at frequencies below 100 kHz and sound energy radiated from the rear and sides of the transducer element is substantially absorbed while a forward beam is obtained.

Abstract: 1,259,526. Transistor logic circuits. NORTH AMERICAN ROCKWELL CORP. 10 Nov., 1969 [7 March, 1969], No. 54959/69. Heading H3T. An output terminal 2 of a logic circuit is set to one potential V 0  or another V 1  in accordance with the logic state at an input terminal 3 by switches such as FETs 8, 4 which are controlled from the input 3 by respective control circuits operating from a multi-phase clock source and each including a capacitive digit store C21, C16. A logic unit 24 derives from inputs 25 an unspecified function which appears at 3 during the # i  time to charge C18. Clock phases # j , # k , # m  all last for at least part of # i  time and extend later than the end of # i  time. They may all be coincident or each may respectively last longer than the previous one, and all must end before # 1  time (Fig. 2, not shown). If the potential at 3 is earth (0) then FET 23 is off, and during # m  time FET 22 is on to negatively charge C20, C21 from # m  source. After # m  ends C20, C21 are isolated and store their charge, so that when # 1  goes negative FET 19 conducts, the bootstrap action of C20 enhancing the conduction. Consequently C11 charges negatively turning on FET 8 to drive the output to V 0  representing 0. Simultaneously, the FET 17 conducts the 0 at input 3 during # k  time to maintain C16, C15 discharged and FETs 14, 4 off. If the input at 3 is negative (1), then FET 17 conducts during # k  to charge C16 and C15, so that FET 14 will conduct in # 1  time to turn on FET 4 and connect the output 2 to V 1  (1). Simultaneously FET 23 is turned on to discharge C21 during the period between # m  and # 1  times when # m  is at earth. Thus FETs 19 and 8 are off in # 1  time.

Abstract: 1,264,932. Electric control of typewriters. OLYMPIA BUROSYSTEME G.m.b.H. 20 May, 1970 [21 May, 1969], No. 24340/70. Heading G4H. In an electric typewriter of the kind in which a type bar is selected for actuation by displacement of a combination of coding rails, an indication is given as to whether a type bar to be actuated is the same as, or different from the last actuated type bar by the read leads W3, W4, Fig. 2, of a storage core RK, the core being brought to one magnetic state by energization of the coil S"O", Fig. 2, moving the coding rail to the unactuated position and to the opposite magnetic state by energization of the coil S"L" moving the coding rail to the actuated position. Because of the need for a type bar to return to its initial position between operations the time needed to print the same character twice is longer than that required to print two different characters. Each coding rail is moved to, or retained in the "O" position by coil S "O" and moved to or retained in the "L" position by coil S"L". The energizing currents of the coils S"O" and S"L" flow through windings W1, W2 of core RK wound so as to set it in opposite states. If a subsequent energization moves the coding rail, it also switches the core, giving an output on read windings W3 or W4. This signal, passed through diode D5 or D6 to output Ua, indicates that the character to be printed is different from the previous one. In the form of Fig. 5 the setting and resetting windings of the core RK are connected through diodes D13 and D14 in parallel with the actuating coils. The inductance of the coils being greater than the windings, current does not flow through the windings until after the energization of the associated coil.

Abstract: 1289202 Holography PERKIN-ELMER CORP 21 April 1970 [25 April 1969] 19000/70 Heading G2J [Also in Division G4] Sound is optically analyzed by spatially  modulating a beam of coherent radiation according to information contained in a sound, comparing the modulated beam with a number of records, and producing an output indicative of a match between the modulated beam and one of the records. A spoken digit 0-9 to be recognized is passed from a microphone 10 to a frequency analyzer 11, the intensity of each of a number of frequencies being recorded electrostatically in a respective longitudinal channel of a continuously-moving dielectric tape 22. A series of intensities on each of the channels are tapped simultaneously by a light modulator 13, each intensity causing a respective electrode 26 to deflect (to an extent depending on the intensity value) a respective area of a reflecting membrane 23. Coherent light from a laser 14, expanded by a lens system 30 and passed via a beam-splitter 15, is reflected from the membrane 23 and thus modulated in phase, then passed to the beam-splitter 15, lens 31, hologram 32, lens 33, and array of masks 34. The hologram 32 produces an image on each of the masks 34 which correspond to digits 0-9 respectively. Only one mask produces an output from a respective photocell 36 which exceeds a threshold. The invention may also be used for speech defect diagnosis, speaker identification, or acoustic signature analysis of non-human sounds. (For figure see next page)
