Title: Improvements in and relating to elements displaceable in a predetermined path and the electrical actuation of recording or other gear according to the displacements of the elements
IPC: G01B7/16
Filed: 1946-06-06
Abstract: 622,934. Electric selective signalling systems. DICK, A. W. H., and DELTA METAL CO., Ltd. June 6, 1946, No. 17245. [Class 40 (i)] A moving body traverses a series of contacts to complete the circuits of actuators controlling another body so that it follows the movement of the first body, the actuators being moved transversely of the second body to effect its step-by-step movement through the medium of a cam. As described, a mercury column 1, Fig. 4, traverses a series of contacts 2 connected to terminals 27 traversed by brushes 28, 29 attached to a carriage 4, Fig. 1, which is to move in accordance with the mercury column; brushes 24, 25, 26, also mounted on the carriage 4, traverse terminals 23 of solenoids 13; when the mercury column rises, relay 32 is actuated to energize solenoid 13c and cause the displacement upwards-of a cam 15, Fig. 1, which bears on a roller 9 and draws the carriage forward against the tension of weight 12 on cord 10; the carriage thus moves forward one step carrying its brushes so that brushes 28 and 25 move forward to energize relay 30 and hold solenoid 13c energized, brushes 29, 24 move forward to de-energize relay 32 and prepare the solenoid next adjacent solenoid 13c to be energized by relay 32, and brush 26 moves forward to energize the immediately preceding solenoid 13b. When the mercury column falls, relay 30 is de-energized to de-energize solenoid 13b and retract the corresponding wedge cam to allow the carriage to retract one step, carrying its brushes with it and causing the two immediately preceding solenoids to be energized. The carriage carries a rotating drum 3 upon which a stylus 5 records at each step, being actuated by relay 35; the solenoids 13 momentarily close contacts 38 to energize relays 35, 39; relay 39 short-circuits contacts 38 to maintain relays 35, 39 energized and when the stylus has completed its movement to mark (e.g. prick) the record, it opens contacts 40 to de-energize relays 35, 39; when the stylus returns to its non-marking position, contacts 40 are closed. The mercury column may be replaced by a non-conducting column having a conducting head, or by the needle of an ammeter moving over contacts.

Title: Process for the preparation of oxazolines
IPC: C07D263/14
Filed: 1966-04-20
Abstract: Oxazolines of the formula <FORM:1123675/C2/1> wherein R is hydrogen, a hydrocarbon radical, a halogenated hydrocarbon radical, or a hydrocarbon or halohydrocarbon radical which contains one or more etheric oxygen atoms, are obtained by mixing an amide of the formula <FORM:1123675/C2/2> wherein X is chlorine or bromine, with sodium carbonate to give a reaction mixture which is substantially free of water and heating the reaction mixture under conditions of temperature and pressure at which the desired oxazoline is distilled off.  The pressure is generally adjusted so that the oxazoline boils at 50-150 DEG  C. and preferably 0.5 to 3 mo's of sodium carbonate, preferably in the anhydrous form, are employed per mole of amide starting material.

Title: Improvements in or relating to arrangements for analysing documents
IPC: G06V30/224
Filed: 1964-04-27
Abstract: 1,014,929. Automatic character reading. COMPAGNIE DES MACHINES BULL. April 27, 1964 [May 30, 1963], No. 17437/64. Heading G4R. In a system for recognizing in motion characters, Fig. 1, formed of a fixed number of vertical strokes a first circuit derives a pulse from the rear edge of each stroke, detects those intervals which are longer than the others and stores corresponding signals and a second similar circuit derives a pulse from the leading edge of each stroke, detects long intervals and stores corresponding signals and logical circuits compare the first and second storage means to generate an error signal if there is an abnormal time shift between the stored interval signals produced by the rear and leading edges. The circuit is shown in Figs. 4A, 4B, and the signals produced are shown in Fig. 5. The wave 34 is derived from a magnetic or other reading head, is applied to detector DT1 which gives a signal shortly after the leading edge, and zero detector DT2 which gives a signal at the trailing edge of a character stroke. Flip-flop B1 is set and reset by these signals as shown at b1, Fig. 5, the resetting triggers monostable circuit M1 to produce pulses m1 (Fig. 5) the rear edges of which cause differentiator DE1 to give pulses del. The output from M1 starts time base BT1 to provide a rising voltage bt1. Flip-flops B2, B3, reset by the pulse de1 are controlled by threshold comparators CL1 and CTL1. The first responds to a long interval, the time base output having at time t12, risen to the threshold level. The second comparator CTL1 has a higher threshold so as to respond to the very long interval between characters. The second circuit, Fig. 4B, is similar except that the monostable circuit M2 is triggered by detector DT3 at the leading edge. The rest of the circuit is the same and the signals produced should be the same as for the first circuit but leading by the width of a stroke. Flip-flop B6 delays the interval signals by this amount so that those from flip-flop B2 and those from flip-flop B6 should coincide. An arrangement of Or gates 36, 37 and And gate 38 compares the signals for coincidence and an error flip-flop B7 is set if there is any difference. Difference may occur through the presence of a spurious mark 20, Fig. 1, which causes a distortion of signal 34, Fig. 5, as shown at 24. The signals of the trailing end circuit are displaced by this mark since the zero crossing at t6 is delayed until t9. Accordingly, a long interval signal is produced t8 as shown in signal btl<SP>1</SP> and the flip-flop B2 has a corresponding output b2<SP>1</SP> instead of the correct output b2. Comparison of the outputs of flip-flops B2 and B6 now gives an error signal preventing the incorrect output of B2 from being passed to the recognition circuitry.

Title: Improvements in fasteners
IPC: F16B5/12
Filed: 1937-06-23
Abstract: 497,719. Press-stud fasteners. FERNBERG, E. B. June 23, 1937, No. 17533. [Class 44] A fastener particularly for securing trim panels, carpets, and the like in motor cars comprises a strip of spring steel bent to provide shouldered limbs 30, Fig. 1, adapted to snap into engagement behind the edges of an aperture provided in the support, not shown, to which the panel is to be secured, one or both limbs being provided with an out-turned foot 34 by which the fastener is held in a retaining member secured to the panel by prongs. Figs. 2 shows a retaining member of rectangular form with four securing prongs 31 and an aperture 32 through which the limbs 30 are passed from below before securing the retainer to the panel. The feet 34 are freely held under the recessed portions 33 so that the limbs can be compressed during insertion in the support aperture, and the fastener as a whole has limited movement to allow for inexact registration between the fastener and the support aperture. To allow engagement of the fastener with the retainer after the latter has been secured to the panel, one foot may be longer than the other, the longer foot being first passed through the aperture 32 from above, and the fastener being then compressed to allow insertion of the shorter foot. Modifications are described in which, respectively, the prongs are at the ends instead of the sides, as shown, the retainer has longitudinal strengthening grooves, the retainer is of triangular form with three prongs, and the retainer is of circular form with a circular aperture. In a further form, Fig. 11, the aperture is of open-ended slot form so that the foot retaining portions are connected by a single integral web 39. The web 39 may be omitted so that the two retaining portions are independent, and in modifications of this arrangement the retainers are simple staples of wire or sheet metal. Fig. 12 shows the connecting web 39 used to retain the fastener which has a single foot with upturned end 40 to prevent removal. A fastener of this form may be used with a retainer generally resembling that of Fig. 2 but having a smaller aperture 32 engaged by the upturned end 40. Fig. 7 shows a fastener in which the ends 37 of the feet are bent inwards to engage under the edges of a non-apertured retainer. Fig. 16 shows a retainer made of wire and having depending loops 43 which are passed through apertures in the panel 44, Fig. 17, and fixed by clinching or deforming as shown. A retaining wire or the like may be passed through the loops. Specification 451,721 is referred to.

Abstract: 1,177,285. Resistors. HUGHES AIRCRAFT CO. 19 April, 1967 [2 May, 1966], No. 17972/67. Heading H1S. A thin film impedance arrangement comprises a primary resistor 73 on an insulating substrate, e.g. glass or ceramic and a plurality of secondary resistors 80 to 86 with their resistance values increasing in consecutive powers of two connected to the primary resistor. A plurality of fusible highly conductive elements 90 to 96 may be connected to the secondary resistors such that the arrangement can be adjusted to a precise resistance value by selectively connecting or disconnecting appropriate ones of the secondary resistances in circuit with the primary resistance. The resistances may be made by depositing resistive material such as nickelchromium or other metal, alloy or metaldielectric combination, followed by a highly conductive layer of e.g. copper and finally a protective layer of e.g. gold. Unwanted gold, copper and nickel-chromium is then etched away by photo-etching or masking leaving resistors and terminals (Fig. 1, not shown). The secondary resistances may be in parallel with the basic resistor and each other (Fig. 4, not shown); trimming of the arrangement may be by electrically fusing with a pulsed current, handscribing or sandblasting the required fuse portions to provide resistance increments. The fuse portions may be thin-films with restrictions for fusing. A modification (Fig. 7, not shown) describes the use of a shunt (120) of e.g. silver, between secondary resistors. The resistor arrangements may be produced, trimmed and monitored automatically.
