Title: Improvements in or relating to fastening devices for motor vehicle bonnets and the like
IPC: E05B65/19
Filed: 1945-10-15
Abstract: 602,395. Fastenings. BINKS, C. L., and AMAL, Ltd. Oct. 15, 1945, No. 26886. [Class 44] A fastening device for bonnets of motor vehicles and the like comprises crank 12 carried on an operating spindle 11 extending through and bearing in back plate 3 which is secured to fixed panel 4, rocker arm 7 pivoted to plate 3 and hairpin toggle spring 18 whose arms 19, 20 are pivotally secured to 12 and 7. On turning spindle 11 by means of handle 17 to fasten the bonnet, spring 18 moves bodily with consequent movement of arm 7 into engagement with co-operating member 9 as shown and subsequently exerts spring pressure by toggle action on 7. Plate 3 carries a stop 24 to arrest further movement of the crank 12 beyond the optimum position for satisfactory toggle action. A drawbar 22 which may be integral with spring 18 or a sheet-metal member having an elongated slot therein, effects positive opening movement of arm 7. Initial outward movement of bonnet may be prevented by bending the horizontal portion of member 9 to form a vertical upstanding leg to engage the innermost side of arm 7.

Title: Data recovery system
IPC: G11B20/10
Filed: 1976-06-29
Abstract: 1513634 Magnetic data storage and retrieval systems NCR CORP 29 June 1976 [7 July 1975] 26975/76 Heading G4A Either data sensed from a movable magnetic storage medium 14, such as a disc, or data produced by a test data generator 40 is coupled to clock generating means, the timing of the sensed and of the test data signals with respect to frame signals generated from clock signals produced by the clock generating means being controllable by means 22, 74, 182 responsive to control signals CS. The data sensed from the medium 14 is encoded in a self-clocking code such as a MFM (modified frequency modulation) code, wherein a 1 bit is represented as a positive transition in the second half of a bit cell and a 0 bit as a positive transition in the first half of a bit cell, except when a 0 bit follows a 1 bit in which case the 0 bit has no positive transition in the bit cell. Ideally the positive transition should occur in the centre of either the first half or the second half of a bit cell but, owing to disc skew and propagation delay in a data detection circuit 50, this is not so in practice, where in the positive transition may occur either early or late within a bit cell. Accordingly the test data generator 40 generates a MFM signal and a MFMJ signal obtained therefrom, the MFMJ signal being skewed by a predetermined amount from the MFM signal, which in turn represents a predetermined sequence of binary digits encoded in a MFM code. In operation, the propagation delay in the data detection circuit 50 is determined by applying the MFMJ signal to the clock generating means. Each of the taps of tapped delay line 74 is successively coupled by the multiplexer 182 to the data detection circuit 50, thereby varying the timing of the MFMJ signal relative to the frame signals, and those taps for which a read error (as detected by known circuitry) occurs noted, this yielding the propagation delay. This propagation delay is then compensated for during subsequent sensing of data from the medium 14 by suitable selection of a tap of the tapped delay line 74 to be coupled to the data detection circuit 50.

Title: Electro-erosion machine tools
IPC: B23Q5/40
Filed: 1961-07-26
Abstract: 907,959. Electro-erosion. GENERAL MOTORS CORPORATION. July 26, 1961 [Aug. 10, 1960], No. 27063/61. Class 83 (4). An electro-erosion machine has an electrode carrier 15 movable towards the workpiece 29, and an electrically driven screw mechanism 10 for advancing the electrode relatively to the carrier to compensate for electrode wear, upon actuation of a switch 54 by excessive movement of the carrier 15, the advance movement being stopped by a timer. The electrode 28 which may be of rectangular cross-section, Fig. 5 (not shown), is clamped in a holder 24 by spring-loaded jaws 40 opened manually by an arm 36, Fig. 2 (not shown). Holder 24 is mounted for sliding movement along guideways 26 by a lead screw 14 to which it is releasably engaged by mechanism 35, Figs. 3, 4 (not shown). The screw is rotated through a one-way clutch 22 by a rotary solenoid 20. Carrier 15 is advanced automatically by a servomotor 16 to initiate the sparking and when the electrode has a predetermined amount of wear, the resulting excess movement of the carrier actuates a switch 54 which closes one of a pair of series switches in the electrode advance circuit. At the end of that particular feed movement, the carrier 15 actuates a second switch 60 which closes the second series switch whereupon solenoid 20 is energized to drive the screw 14 and advance the electrode. An adjustable electronic timer 70, 74, Fig. 6 (not shown), subsequently actuates a relay to open the series switches. When the electrode requires replacement, the extra movement of carrier 15 actuates a switch 78 which energizes a warning lamp.

Abstract: 1279182 Logic circuits; parity checking; digital transmission systems SIEMENS AG 8 June 1970 [9 June 1969] 27522/70 Headings H3T and H4P A logic circuit for three input signals a, b and c comprises four common emitter transistor pairs and a transistor output circuit T11, T12 arranged substantially as shown whereby it may indicate the presence of one and three of the signals (i.e. an odd number) or with some reversal of connections the presence of none and any two only (i.e. an even number). In the circuit as shown the transistors T1 to T6 perform the logic Z=a.b+a.b and z=a.b+a.b Transistors T9 and T10 perform the logic c(a.b+a.b) and c(a.b+a.b). When these signals are combined by T11 and T12 the circuit performs the logic a.b.c+a.b.c+a.b.c+a.b.c (which is also the summing output of a full adder). Transistor 8 is a level shifter and the diodes limit the voltage drop across the associated collector resistors. The even function a.b.c+a.b.c. +a.b.c+a.b.c may be obtained by reversing the connections to T9 and T10, at collector or base, or the base connections of T5 and T6 as by altering external connections to the circuit chip. Higher orders of even or odd parity may be obtained by one of a number of the circuits (Fig. 2, not shown) either of the same or of mixed parity types. In the latter case, conversion from even to odd may be effected by altering the connections to the output logic only.

[Class 100 (ii)] In a multicolour rotary printing-machine having printing-rollers fitted with box-wheel adjustment devices as in the parent Specification in which a brake causes angular adjustment of the printing-roller in one or other direction depending on the engagement of a sliding gear c<1> with a gear wheel d or e, the gear c<1> is arranged to be moved axially by external control means through a distance limited by stops. The gear c<1> is carried by a sleeve c attached to a brake drum b formed with two internal conical brake surfaces b<1> with which coact similar surfaces h on a wheel attached to a non-rotating spindle i, which is actuated by a lever k fitted with flexible cables l for moving the lever positively in both directions. A bearing bracket j serves as a stop for limiting the movements of the gear c<1>. When the spindle i is moved in either direction it carries the wheel h with it and this transmits motion to the brake drum b, sleeve c, and gear c<1>. Upon stoppage of the drum b by the stop j, further movement of the wheel h exerts a braking action which causes angular adjustment of the printing-roller. The lever k is normally kept in a vertical position by a weight, and the gear c<1> is out of mesh with the gears e, d.
