Title: Apparatus for modifying electrical pulse waveforms
IPC: H03K5/06
Filed: 1963-09-13
Abstract: 1,012,904. Pulse circuits; pulse radar. RAYTHEON CO. Sept. 13, 1963 [Oct. 1, 1962], No. 36242/63. Headings H3P and H4D. An arrangement comprises means for delaying an input signal by successive amounts less than the width of a peak in the input signal and for so weighting the delayed signals relative to each other as to sign and magnitude that the delayed signals combined by further means form an output signal having a peak therein substantially narrowed with respect to the peak in the input signal. The delay means may be a " lumped " line 12, a distributed delay line, a magnetostrictive device or a magnetic tape delay device. In the embodiments weighting is accomplished by selection of the values of resistors, and this selection is defined mathematically. Tables are included for determining the weighting factors for different combinations of output wanted signal-to-spurious signal and pulse compression ratios. Figs. 2 and 3 (neither shown) depict the waveforms arising when the input signal corresponds to one radar or sonar echo and to two overlapping echoes respectively, resolution improvement occurs. In a pulse radar, Fig. 4, the receiver incorporates sequential mixers 64, 66 and associated local oscillators 62, 68, and the device 70 according to the invention is fed from mixer 66; in an alternative arrangement device 70 is put at the output of mixer 64, the tap spacings on the delay line being at integral multiples of the I.F. wave period. In a modification of the Fig. 4 embodiment for moving target indication by utilizing a phase coherent oscillator, as given in pages 1033 to 1036 of " Electronic and Radio Engineering," 4th edition, by F. E. Terman, the device according to the invention is placed either after the phase detector, Fig. 26-16 therein (in which case signals from all targets will be resolved) or after the subtracting circuit (in which case only moving target signals will be resolved); the limiter of Fig. 26-16 has to be removed. In an example of the device for providing a pulse compression ratio of 8: 1 and a wanted-to-spurious signal ratio of 10:1, Figs. 5 and 6 (neither shown), forty taps on the delay line are utilized and resistor values are quoted. To afford an output pulse independent of the phase difference between the signals mixed in mixer 66 there is added a second oscillator similar to oscillator 68 but in phase quadrature therewith and a further mixer receiving the output of mixer 64, the resultant mixer output being fed to another device 70 and the outputs of the two devices being combined.

Title: Improvements in braking device for fishing reels
IPC: A01K89/0155
Filed: 1956-11-27
Abstract: 809,014. Centrifugal brakes. KLINGBERG, A.I. Nov. 27,1956 [Dec. 15, 1955], No. 36311/56. Class 103 (1). [Also in Group VI] A centrifugal brake on a fishing reel (see Group VI) comprises a brake block 10 pivoted on a pin 11 secured to the spool 2 and having a brake shoe 13 adapted to engage the outer peripheral surface of a collar 4 on the frame 1 of the reel. The braking power is adjusted by a screw 14 which screws into the brake block and has a head 15 constituting a weight and projecting through a radial slot 16 in the top 6 of the spool; the braking power is increased as the screw 14 is unscrewed. The screw 14 can be screwed in far enough to locate the centre of gravity of the assembly of brake block and screw below the level of the pivot pin 11 and in this position there is no braking effect. In a modification the brake shoe engages the inner peripheral surface of the collar 4 and in a further modification the brake shoe engages the concave wall of the frame. In both these modifications the braking power is decreased by unscrewing the screw 14. In the reel shown in Fig. 5 the pivoted brake block 50 is mounted in one of the cup-shaped discs of the spool and co-operates with a brake drum 53 secured to the frame. The brake adjusting screw 54 is accessible to a screwdriver through an opening 55 in the frame. As the screw is unscrewed the braking power increases. In a modification the brake shoe is located near the other end of the block and consequently the braking power decreases as the screw is unscrewed.

Filed: 1958-11-14
Abstract: 874,740. Bistable discharge tube circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 14, 1958 [Nov. 18, 1957], No. 36715/58. Class 40(6) [Also in Group XIX] A bistable trigger circuit comprises a pair of electric discharge tubes reciprocally coupled between their anodes and control grids with a unidirectional conducting device connected between their cathodes, input triggering signals are applied to each tube to trigger the device to its respective states. Fig. 1 shows a bistable trigger circuit comprising reciprocally coupled triode tubes 20, 21 in which diode 40 is connected between the cathodes and in which the circuit is triggered by negative-going input pulses applied to the respective grids of the tubes. It is shown that if initially tube 20 is conducting and tube 21 cut off, the first negative pulse 22 applied to the grid of tube 20 will cause tube 20 to be cut off and tube 21 to conduct. Subsequent pulses at the grid of tube 20 will be ineffective, the state of the trigger pair being restored only by a negative input pulse 44 applied to the grid of the right hand tube 21. Output pulses may be taken from either the anode of tube 20 or the cathode of tube 21. A counting circuit, (Fig. 3, not shown) (see Group XIX), comprises bi-stable switching units as shown in Fig. 1 connected in a closed ring.

Title: Fluid dispensing devices
IPC: E03D9/03
Filed: 1972-08-03
Abstract: 1364063 Disinfecting and deodorising toilets UNI-HYGEA Ltd 3 Aug 1972 [5 Aug 1971 15 Oct 1971] 36741/71 and 48003/71 Heading E1C . Apparatus for simultaneously adding a disinfectant to the water in a toilet cistern and spraying a de-odorant into the air comprises a variable volume chamber, e.g. a bellows 6, which is connected by a pipe to an air trap vessel (100, Fig. 3, not shown) or equivalent device in a toilet cistern, such that a rise in water level in the cistern increases the volume of the chamber 6 against the restoring force of a suspended weight 45 or a spring, and a fluid-dispensing pump 10 which is operated by the weight or spring, when the water level descends, through a lost-motion device, to supply disinfectant fluid from a container 8 to the cistern. The movement of the bellows may also actuate a metering valve 82 of an aerosol container 80 containing spray de-odorant. The operating mechanism comprises a pair of vertical bars 44 which straddle the pump 10 and pass through a central aperture in the bellows, which are of annular form, to connect the weight 45 with a sleeve 46, which rests on the bellows, by way of a latching lever 70 pivoted on the sleeve at 68 and having a pin 74 at its lower end normally engaged in a notch 70a in a slot 70 formed in each of the bars. A lost-motion connection in the form of a pin 48 and slot 50 connects the bars 44 to a piston rod 36 carrying a piston 34 working in a cylinder 18 surrounded by a casing 14 which is in two parts, the lower of which carries a spring-loaded delivery valve 22. Reciprocation of piston 34 alternately creates a vacuum until part 40 is uncovered to suck in disinfectant fluid from annular chamber 18, which connects with the container 8 via port 20, and forces the fluid past valve 22 to delivery port 28, which is connected by a pipe 30 (Fig. 3, not shown) to the cistern. This reciprocation is effected as follows: first, the bellows rise to the position of Fig. 2 on filling of the cistern, at which position a notch 64 in each of the bars 44 is engaged by a spring-loaded latching pin 58 to retain the bars in raised position. Then, during flushing of the toilet, the bellows fall, causing pin 74 to disengage the notch 70a in each bar 44 and ride along cam surface 70b for distance sufficient to cause, the upper end of the latching lever 70 to disengage the pin 58, whereupon the bars 44 fall until the pin 74 re-engages the notch 70a, the momentum thus obtained being further increased by the lost-motion connection 48, 50 until piston 34 is driven whereby a shot of disinfectant fluid is delivered towards the end of the flush. At the same time, by the engagement of projecting ends 54a of a pin 54 with free ends 90a of pivoted arms 90, these arms are depressed to operate the metering valve 82 to spray a predetermined quantity of de-odorant into the room from aerosol container 80.

Title: Improvements in or relating to the stiffening of boot or shoe uppers
IPC: A43B23/08
Filed: 1930-12-08
Abstract: 368,756. Boots &c. BRITISH UNITED SHOE MACHINERY CO., Ltd., CLARKE, G., and LUND, W. J., Union Works, Bel. grave Road, Leicester. Dec. 8, 1930, No. 36895. [Class 17 (ii).] Stiffeners.-Relates to the stiffening of the toe ends of uppers, particularly single layer uppers, e.g. Veldtshoen sandals, and consists in applying to the interior side of the upper a coating of material adapted to strike, when in liquid or semi-liquid form into the fibres of the upper and by impregnation and subsequent setting to stiffen the toe portion, the coating being unaccompanied by sheet material as an absorbent. Preferably, a guarding layer of material impervious to the stiffening material is applied to prevent adherence to the last on which the upper is shaped, which layer may be removed when the stiffening has set. Immediately prior to assembly of the upper and last the flesh surface of the upper at the toe may be coated with a high concentration solution of low viscosity nitro cellulosic composition of a nature that will soak into the flesh surface. A guarding layer of flimsy waxed or parchmentized paper, or other flimsy sheet of cellulosic material unaffected by the solvent, as the material known under the registered Trade Mark " Cellophane," or other cellulose film made by the viscose process, is applied. This layer may, after lasting, be severed along the line where it touches the sole and the severed portion removed. Alternatively, a solution of synthetic resin, such as vinyl resin (wholly or mainly polymerized vinyl acetate) may be used, one part by weight of the resin being dissolved in three parts of ethyl acetate. French chalk may be used to prevent adherence to the last. In a further modification, a layer of fibrous cellulosic material soluble in a volatile solvent is reduced to a gelatinous state as described in Specification 289,496, [Class 17 (ii), Boots and shoes, Construction of], the layer being pressed into contact with the flesh side of the upper for a short time before assembly. A toe-puff blank of the knitted fabric known under the registered Trade Mark " Celanese " may be anchored at two or three places to a similar blank of " cellophane," the flesh side of the upper wetted with acetone and the stiffener pressed on to the upper so that the Celanese becomes soft and gelatinous. The stiffener may embody a textile vehicle heavily coated on both sides with material that will set to a coherent smooth film encasing the vehicle and bonding itself securely to the leather. Specification 4058/12, [Class 17 (i), Boots and shoes, Apparatus for making &c.], also is referred to.
