Title: Arrangement for use in detecting an amount of a flowing medium exceeding a preset quantity
IPC: G01D4/14
Filed: 1977-06-02
Abstract: If there is no transgression of limit value within a measuring period predetermined by a time base counter, the pulse counter (1) is reset to its starting position by the time base counter (5) at the end of the measuring period. If, however, the limit value is exceeded within the measuring period, the pulse counter (1) outputs a transgression pulse which increments a transgression counting mechanism (18) by one unit. At the same time, a new measuring period begins. The invention solves the problem of initiating a new measuring period if the limit value of the pulse counter (1) is already exceeded before the measuring period has elapsed. This is done by the fact that the pulse counter (1) and the time base counter (5) are reset to their starting position by the transgression pulse via a monostable flip flop (10). The resetting of the pulse counter (1) by the time base counter (5) at the end of a measuring period without transgression of limit value is also effected via a monostable flip flop (7). <IMAGE>
Patent GB-236443-A (GB)
Abstract: 236,443. Ensch, L. Nov. 19, 1924. Stop-gear. - The ignition in a motor-car engine is controlled jointly by the pressure in the lubricating system and by the regulating mechanism of the fuel feed so that the engine can be started at low speeds even when the lubricating system has failed. The fuel-regulating lever A carries a rod provided with a contact B which engages contact bars F, F' when the fuel supply is increased after starting. A plunger K subject to the lubricating system pressure carries a contact which in its lowest position engages a contact Z. When contact B engages bars F, F<1> and the plunger contact also engages the contact Z, the ignition is short-circuited, but is re-established on withdrawing the contact B to start the engine.

Patent GB-1024949-A (GB)
Title: Light-modulating apparatus
IPC: G02F1/03
Filed: 1964-06-12
Abstract: 1,024,949. Light modulation. SPERRY RAND CORPORATION. June 12, 1964 [June 12, 1963], No. 24458/64. Heading H4F. The invention relates to a light modulating arrangement in which light from a source 15 is plane polarized by a device 17 and is then caused to make a double traverse of a modulating element 22 by means of a reflector 12, the modulating element being controlled to rotate the plane of polarization or directly to introduce an orthogonal component which may be analysed by the device 17 and directed to a detector or other utilization device (not illustrated). The light may be visible, infra-red or ultra-violet, and the modulating element, which may utilize the Faraday, Kerr or Pockles effect, is located in a resonant cavity so as to be controlled (as appropriate) by an electric or magnetic field at a microwave frequency. According to a first feature of the invention, a common device 17 such as a Glan- Thomsen prism, a Nicol prism or a stacked glass-plate assembly, may function as polarizer, analyser and beam splitter for directing to the modulated component to the output. According to a second feature, the light source 15 is associated with a reflector 11 so that the unmodulated component of light, which passes back without deflection through device 17 is returned to make further double traverses of the modulating element. Light source 15 may be a laser in which the light permeable end mirror is also made reflecting on its outer surface. The multiple-reflective light path between reflectors 11 and 12 is made non- resonant by arranging that the surfaces of the reflectors and other elements in the system are made optically-irregular to the extent of the order of one-eighth of a wavelength. According to a third feature, a one-eighth wavelength biaxial plate 20 is included in the light path so as to introduce a 90 degrees phase displacement (on the double traverse) and thereby cause an orthogenal component to be produced in the absence of a modulating signal. In effect plate 20 introduces a bias into the modulation characteristic of the arrangement. The necessary relationship which must be established between the propagation time of the light beam in its double traverse of element 22 and the period of the microwave signal is discussed with reference to Fig. 2 (not shown). Modulation characteristics of the arrangement are described with reference to Figs. 3 and 4 (not shown).

The Specification relates to an improvement of the radio direction finder disclosed in Specification 977,991, wherein, since the phase discriminator 12, Fig. 3, has a non-linear, sinusoidal phase difference versus output voltage characteristic, Fig. 2, the range of variation of the phase difference between the two input signals is compressed such that only the linear part (B 2 -A 2 ) of the characteristics is used, by means of a negative feedback loop, whereby the A.C. variations of the output of the phase discriminator 12 at the frequency of rotation of the aerials, is fed, via a low-pass filter 16 and amplifier 19, to control the phase shifts given to the channel signals by shifters 11 and 11<SP>1</SP>, in such a direction as to cause said compression. The signal applied to the phase shifter, is also applied to the synchronous detectors 13 and 14.

Abstract: 841,452. Railway vehicle automatic couplings. NATIONAL MALLEABLE & STEEL CASTINGS CO. July 30, 1958 [July 31, 1957], No. 24577/58. Class 103(5). An automatic knuckle type railway vehicle coupler has its knuckle 6 provided with lugs 13, 25, Figs. 2 and 8 having surfaces 13a 25a which are engaged when uncoupling by the prongs 21, 22 of a two stage knuckle thrower 18. Increased uncoupling leverage is obtained by arranging the prong 22 to engage the surface 13a before the prong 21 engages the surface 25a, but the continued rotation of the knuckle 6 is effected solely by engagement of the prong 21 with the lug 25. An extension 12 of the knuckle tail 14 extends under a head portion 8a of a lock 8, while a knuckle portion 15 engages a side surface of the lock. The lock 8, Figs. 1 and 3, is provided with a ridge 30 which during uncoupling is engaged in a notch 31 in the coupler wall 33 so that the lock may be swung rearwardly about a point 44 by a bottom operated lock lifter, the heel 41 of the lock leg engaging the forward surface of the arm 20 and swinging the thrower and the knuckle. The re-location of the fulcrum point of the lock 8 to the point 44 eliminates the conventional lug recess in the buffing wall 33 and allows the wall to be made stronger. With a top operated lock lift, Fig. 9, a link 53 has slots 59 and 62 engaging a pin 56 in the lock head and a pin 63 on a link 52, so that in the locked position a shoulder 60 on the link 53 engages a surface 61 on the coupler head. The slack in the slots is greater than the distance 67 to allow a lip 65 to rest on a surface 66 on the head, in which position the lower end of the link 52 cants forwardly so that any sudden upthrust on the link 53 causes the lifter as a whole to jack-knife forwardly and bring the shoulder 60 up to engagement with the surface 61.
