Title: Valve system for a fluid injector
Inventor: TINDALL DAVID
IPC: F23D11/10
Filed: 1991-08-23
Abstract: A valve system for a fluid injector of the type disclosed in GB 2140551 A comprises first and second flow paths 17, 36 each containing a rotary ball valve 9, 8 respectively and connected by a by-pass duct 60. The valve 9 of Figure 6A blocks flow along the duct 60 when the flow path 17 is open and opens the duct 60 when the flow path 17 is closed. In the valve system of Figure 7A, flow along the duct 60 is controlled by pressure responsive valves 104 arranged one in each flow path 17, 36. In Figure 8A (not shown) a valve in the duct 60 is operated via a cam by the drive of the valves 9, 8. In Figure 9A (not shown) a pressure responsive valve, which may be spring biassed, is arranged in the duct 60 so as to permit or prevent throughflow. <IMAGE>

IPC: G01R21/133
Filed: 1991-09-19
Abstract: A method for generating a product of first and second signals proportional to a supply voltage and a load current comprises frequency modulating (4, 5 Figure 1) two carrier signals by the voltage and current signals to produce third and fourth signals V/Fv and V/Fi (Figure 2); normalising (22, 25) the third and fourth signals with reference to frequencies corresponding to zero voltage (17-19) and zero current (34-36); and multiplying (26) the normalised third and fourth signals to form a product signal proportional to power. A timer device (Figure 3 not shown) is employed for voltage to frequency conversion. A microprocessor is programmed to compute real and apparent power. A calibration arrangement is described with reference to Figure 5 (not shown) and the meter may include a card reading facility as in Figures 6-10 (not shown). <IMAGE>

Title: Transmitter/receiver output/input stages
Inventor: BATES THOMAS
IPC: H04B1/54
Filed: 1992-10-21
Abstract: A transmitter/receiver output/input stage comprises first (21) and second (23) mixers and first (25) and second (27) oscillators the second (27) of which is a variable frequency oscillator. As a receiver input stage the first mixer (21) mixes a received signal with a signal generated by the first oscillator (25) to provide a first signal to the second mixer (23). The second mixer (23) mixes the first signal with a signal generated by the second oscillator (27) to provide an output signal of a predetermined frequency. As a transmitter output stage the second oscillator (27) is retuned to the frequency of the first signal to provide to the first mixer (21) a second signal, the first mixer (21) mixing the second signal with the signal generated by the first oscillator (25) to provide an output signal at the frequency of the received signal. <IMAGE>
Patent GB-929411-A (GB)
IPC: A41D27/20
Abstract: 929,411. Sewing-machines; garment pockets. G. M. PFAFF A.G. Aug. 19, 1959 [Nov. 5, 1958], No. 28293/59. Classes 112 and 141. In a method of making a piped opening in a cut-out garment part 2 or the like, flat folded piping material 1 is sewn to the base material by means of a two-needle sewing-machine so that when the garment is disposed above the piping the latter may be sewn to the garment by parallel seams 4 in accordance with markings on the base material. Folding apparatus 21 for the piping comprises a folding sleeve 24 and two slides 25 mounted on a base-plate 23. For guidance of the piping as far as the needles, prongs 28 extend from the sleeve 24. A stud 30, see Fig. 6, on the base of the sleeve 24 engages in a groove 31 in the base-plate 23. Projections 34 of slides 25 engage in apertures 33 in extensions of the sleeve 24 and outer edges 35 of the slides are turned up to form handles. Strip guides 36, adjustable in width are thus formed between the stud 30 and the projections 34. A strip 39 is fed into the left-hand strip guide (Fig. 9) before sewing and the piping 1 is inserted into the sleeve 24, both parts having their front edges just behind the presser foot 15. The garment part 2 is placed under the presser foot with transverse marks 40 directly below the needles 13, the first longitudinal mark 41 is aligned with a notch 19, aligned with a slot 17 for a cutter 18, and the pocket lining 42 is applied to the longitudinal marks. The operator sews a length equal to about half the needle spacing, then lowers the cutter 18 and continues sewing keeping the guide marks under the notch 19. The cutter is lifted at about half the needle spacing from the end and the seam continued. The piping ends 7 are cut through by hand, incisions 8 made, the tape 39 and piping 1 cut to length and drawn through the slit 6 and the flaps 9 are stitched to the piping ends. The tape 39 is sewn to the pocket lining 42 and the opposite edge of the pocket lining is turned over and sewn to the edges 51 of the piping 1 as in Fig. 12. In an alternative form of sleeve, the piping material is folded to give three layers of material before cutting and one edge lies outside the fold lines. After sewing and pulling through, this edge serves the same purpose as the tape 39.

Patent GB-2286667-A (GB)
Title: Smoke detector
Inventor: SHEEHAN JOHN A
IPC: G08B17/107
Filed: 1994-02-15
Abstract: A smoke detector comprises a light emitter (10) and a light receiver (11). Normally, light from the light emitter (10) is partially absorbed and partially deflected by parallel posts (2, 3) which lie on a straight line (21) on which the light emitter (10) and the light receiver (11) also lie, with the result that no signal is generated. When smoke enters a chamber (6) containing the posts (2, 3) it causes the light to be diffused and sufficient light reaches the light receiver to cause the generation of an electrical signal. The light emitter, posts, and light receiver may be mounted on a plate (1, Figure 2) which has a circular ring of baffle posts (4, Figure 2) which prevent outside light entering the smoke detector. <IMAGE>

Title: Phase-locking circuit for swept synthesized source having stability enhancement circuit
Inventor: JAFFE STANLEY E
IPC: H03B1/00
Filed: 1992-07-21
Abstract: Hysteresis, tuning nonlinearity, and drift over time and temperature of an oscillator incorporated into the PLL of a swept synthesized source are compensated. The tuning current to the oscillator is initialized to zero to eliminate hysteresis effects. Then, the pretune current is set to produce the minimum operating frequency of the oscillator. Next, the main phase-lock loop is closed, and a low-frequency synthesizer (16, Fig. 4) is swept to in turn sweep the oscillator over a selected frequency span. In order to improve phase-noise and transient response performance of the low-frequency synthesizer, a phase-lock loop speed-up and stability enhancement circuit 66 comprising a zener diode 66A is connected across a passive lag-lead network 64'. The zener diode enables asymmetric charging and discharging of a capacitor 64A' in the lag-lead network to maintain loop stability (to avoid ringing and oscillation) by preventing loop saturation, especially for large changes in the divide number, N, and thereby enhance the stability, phase-noise performance, and transient response of the phase-lock loop of the low-frequency synthesizer. Pretune calibration for the swept synthesized source is also provided. <IMAGE>

Title: Deodorizing filter
Inventor: KADOWAKI SATORU
IPC: B01D53/04
Filed: 1995-09-11
Abstract: A flexible porous material formed into a flat plate is used as a porous material (2) carrying adsorbents for adsorbing foul-odor components in gas. Slits (2a, 2b) are alternately formed in front and back sides of this porous material such that the slits are formed to a midway along the thickness in a thickness direction and the porous material is then extended in plane direction to be formed into pleats wherein a bottom portion of a slit becomes an angle portion thereof. When compared with a flat plate-like material, the pleated porous material formed as above has a filtering area remarkably increased to reduce the flow velocity of air passing through the filter, to thereby reduce remarkably the pressure loss. Therefore, since there is generated extra margin in attainment of a target pressure loss, it is possible to increase the volume of adsorbents carried by the porous material, thereby making it possible to improve deodorizing performance remarkably.
