Title: Improvements relating to electronic organ keying circuits
IPC: G10H1/057
Filed: 1968-06-25
Abstract: 1,212,128. Electronic organs. WURLITZER CO. 25 June, 1968 [26 June, 1967], No.30269/68. Heading G5J. Each of the tone generator signals in an electric organ is switched by forward biasing diodes in response to closure of different contacts of octave related keys according to whether 4, 8 or 16 foot stops are used, isolating diodes being provided to prevent false notes sounding when a plurality of keys are operated. The normally non-conductive diodes 106 and 110 are switched on by a positive pulse resulting from actuation of the key switch allowing + 23 volts from bus 38 to pass to the diodes. After actuation of the key switch, capacitor 132 holds the charge which decays at a predetermined rate through a common sustain circuit described hereinafter, hence keeping the diodes continued for a predetermined time. The generator output is fed to associated filters and amplifiers through resistors 118 and 120. In order to lock diodes 70, 76, 80 hard off a bias of +2.2v. is effect of rendering diodes 106 and 110 normally almost in a conducting condition to minimize noise when they are rendered conductive. The sustain circuit provides four different rates of decay of charge from capacitor 132 by three switches 162, 166, 184. With the switches in the position shown in Fig. 3, the charge decays through terminal 138, line 202, line 180, resistor 174 to - 30v. Hence the capacitor 132 decays almost instantaneously. With switch 166 moved to the right the connection is to + 2.2v. rather than -30v. and the decay is slower. With both contacts of switch 162 moved to the right the capacitor decays through terminal 148, line 210, line 208, resistor 192 and resistor 158 to - 30v. at an intermediate rate owing to the large value of resistor 146. With switch 184 moved to the right capacitor 132 decays slowly through terminal 148, line 210, line 208 and resistor 206 to earth.

Abstract: 466,211. Locking nuts and bolts. BOUR, E. F. Nov. 2, 1935, No. 30299. [Class 89 (i)] A nut 1 is locked on a bolt 2 by means of a set screw 4 engaging in a diametrical threaded hole extending from one of the facets of the nut to the opposite facet, the set screw 4 pressing a piece 3 of deformable material also housed in said hole into engagement with the thread 2a of the bolt 2, which thread is crossmilled or longitudinally serrated. The set screw may be headed or not and the lower end may, as shown in Fig. 4, be concave.

Title: Improvements in plastics lipstick holder
IPC: A45D40/06
Filed: 1965-07-16
Abstract: 1,088,649. Lipstick holders. BRIER MANUFACTURING CO. July 16, 1965 [Aug. 24, 1964], No. 30304/65. Heading B8P. A plastics lipstick holder moulded from a polyvinyl thermoplastic resin such as polystyrene comprises a flexible thin walled cam sleeve 6 having a spiral cam slot 7, an outer sleeve 4 having a longitudinal groove 5 in its inner surface and a lipstick holder 8 from which a lug 9 extends through the cam slot to engage the groove. The outer sleeve 4 is held on the cam sleeve 6 by three protrusions 26 which snap into an annular groove 50 below a rib 40 on the cam sleeve. Rotation of the cam sleeve 6 with respect to the outer sleeve 4 forces the lipstick holder 8 upwards until the lug 9 reaches the top portion (34), Fig. 1 (not shown), of the slot 7. The floor (36) of this top portion (34) is nearly horizontal and further rotation of the sleeve forces the lug 9 against an end wall (38) of the slot 7 thereby wedging the lug firmly between the horizontal floor and a lip 22 of the outer sleeve 4. The horizontal floor (36) thus prevents downward pressure causing lipstick 10 to retract when in the fully opened position. A small gap 57 between the outer and cam sleeves allows easy relative rotation between them but when the lipstock is in a partially open position downward pressure on the lipstick 10 causes the cam sleeve 6 to expand and frictionally engage the inner surface of the outer sleeve 4 thereby preventing accidental retraction of the lipstick. A cover 14 fits over three lugs 44 and abuts against a base 12 which is a friction fit on the bottom 13 of the cam sleeve 6.

Abstract: 994,460. Transistor limiter circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 24, 1961 [Sept. 7, 1960], No. 30566/61. Divided out of 994,458. Heading H3T. A rectifier is arranged in series with a signal path and current biasing circuits are arranged on each side of the rectifier so as normally to maintain the rectifier conducting. The arrangement being such that if the input tends to reduce the output current below a desired minimum value the rectifier becomes non-conductive and the minimum current is provided by the current path on the output side of the rectifier. Fig. 1 shows a variable amplitude pulse source Ic feeding a load OC. The rectifier is normally biased from -V through transistors T1 and T2 so that it conducts but if the input voltage falls below a predetermined potential the rectifier Rf cuts off so that a desired minimum current is still supplied through T2. In Fig. 2 (not shown) the input source is omitted and the variable amplitude input pulses are applied to the base of T1.

Abstract: 424,704. Lace-making. JARDINE, Ltd., J., 26, Deering Street, Nottingham, SWINDALL, J. W., 7, Haddon Road, West Bridgford, Nottinghamshire, MONTGOMERY, H., 1, Sophie Road, Nottingham, and LACEY, W., Harlaxton, Oakdale Road, Carlton, Nottinghamshire. Nov. 4, 1933, No. 30659. [Class 74 (i)] To stop the carriage threading and lace bobbin-exchanging machine described in Specification 210,570, [Class 74 (i)], when a carriage jams in a carrier, the starting lever F is released whenever the driven member B<1> of the clutch B is held otherwise than by a detent lever D. This lever engages stops C on the member B<1> and holds it long enough for a bobbin to be extracted. The lever D is then moved clear of the stop by a cam E. After the stop has gone by, the cam E releases the lever D, which returns into track of the stops on the member B<1>. If not re-engaged in due course by another stop C the lever D will be drawn by a spring so that the end D<2> trips a catch working in a fixed slot F<3> and releases the starting lever F. This stop-motion works well enough when the lever D is midway between two adjacent stops, but if the member B<1> comes to rest with a stop C in the vicinity of the lever D the end D<2> may not trip the catch. To ensure stoppage in this case, a second trip lever J, pivoted alongside the lever D and carrying rolls J<1>, J<2>, is provided. The roll J<2> bears on a gapped cam K, while the roll J<1> drops into a gap in the member B<1> when the gap in the cam K registers with the roll J<2>, should the member B<1> be at rest. The gaps in the member register with the roll J<1> when one of the stops C is at or near the inner end of the lever D. The lever J thus trips the catch in the slot F<3> at a time when the lever D is inoperative. The trip lever J is also acted on to stop the machine when the magazine for receiving empty bobbins is full. There is also provision for taking the weight of a column of bobbins off the ejector slide.
