Abstract: 1,063,992. Automatic exchange equipment. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 24, 1964 [April 26, 1963], No. 16534/63. Heading H4K. A circuit for determining whether a bi-stable circuit BS1 is set in the same condition as a bi-stable circuit BS2, which circuit is employed in an exchange system to compare the identity of incoming junctions with the identity of junctions stored in a register, comprises gates COM A and COM B connected such that if the bi-stable circuits are in one state they extend voltage to COM A and if in the other state they extend voltage to COM B, the gates being pulseplus-bias gates biased by the outputs of BS2 and pulsed when the outputs of BS1 are connected up by switches S1, S2. If the bi-stables are in the condition with their lefthand sections A active output is produced from COM A and if the right-hand sections B are active output is produced from COM B. In either event the output is taken to a common lead Pay. The pulse-plus-bias gate COM A is shown in Fig. 2, a positive bias on Ol1<SP>1</SP> from BS2 raising the junction x to a small negative value so that a pulse on Ol1 from BS1 causes rectifier D1 to conduct. A capacitor C1 decouples BS1 from BS2 while a rectifier D2 prevents the capacitor discharging back into BS2.

Title: Improvements in or relating to shutter release mechanisms for photographic cameras
IPC: G03B9/58
Filed: 1938-06-03
Abstract: 503,055. Photographic cameras. KODAK, Ltd. June 3, 1938, No. 16644. Convention date, June 4, 1937. [Class 98 (i)] In folding cameras in which a shutter release member mounted on the camera housing is automatically retracted and ejected as the camera is closed and opened respectively, the member is connected to a pivoted bellcrank connected at the other end to a link pivoted to a member longitudinally slidable on the camera bed and connected to the shutter, the pivotal connection of link and slidable member being displaced from the hinge axis of the bed when the camera is open so that on closing the bed the slidable member produces a thrust on the link to retract the release member. As shown in Fig. 1, the bed 16 hinged to the camera housing 10 at 18 carries supports 23 for the lens and shutter mechanism; and also a locking plate 28. The release member comprises a plunger 40 having a slot 42 to receive a lug 43 of a pivoted bell-crank 38 and also one end of a coil spring 44 which presses the plunger outwards. A link 45 pivoted at 46 to the crank is pivoted at 47 to a rod 34 sliding longitudinally in a bearing 35 and having an upturned end 36 passing through a slot 37 in the plate 28 and abutting against a pivoted bell-crank connected to the shutter release. Hence on depressing the plunger the rod 34 slides towards the housing 10 to release the shutter, the plunger being returned by the spring 44. The pivot 47 is arranged in front of the hinge 18 when the camera is open so that on closing the camera the end 36 of the rod 34 abuts against the outer end of the slot 37 so that further sliding is prevented, and the link 45 rotates the pawl 38 to retract the plunger 40. On opening the camera the plunger is automatically moved outwards by the spring.

Title: Improvements in receiving apparatus for equi-signal radio-navigation systems
IPC: G01S19/11
Filed: 1944-09-01
Abstract: 628,244. Automatic control of aircraft. SPERRY GYROSCOPE CO Inc. Sept. 1, 1944, No. 16747. Convention date, Sept. 1, 1943. [Class 38 (iv)] [Also in Group XL (c)] A receiving apparatus for an equi-signal radio-navigation system for aircraft, comprises means for mechanically or electrically biassing an indicating instrument of the apparatus so as to provide a fly-up indication whenever no signals reach the instrument and automatic volume control means for automatically counter-balancing the bias when signals from the system represent that the carrier intensity is in the normal operating range for " oncourse." Signals from an overlapping beam glide-path beacon using modulation by two audio frequencies to define the equi-signal path are received on antenna 11 on the aircraft. They pass through frequency-changer 12, fed by local oscillator 13, and a number of intermediate frequency stages 14 to detector 15; the audio output is amplified at 18 and the two frequencies separated by filters 19 and 21, rectified respectively by bridge networks 22 and 23 and the direct currents applied in opposition to centre zero indicator M and also, if desired, a co-pilot's indicator M<SP>1</SP>. An automatic gain control system 16 derives signals from detector 15 and applies a bias voltage to stages 14 and if desired, 18 to control the gain in known manner. Thus meter M reads zero both when on course and when no signals are being received. Failure of the beam or early stages in the receiver when the craft is following the glide path would not affect the " on-course " indication given and so meter M is biassed to a fly-up position for no signals ; this may be done by spring-loading or by the normal adjustment screw. A positive voltage is applied to the meter through resistors 27 and 31, the junction 36 of these two resistors being connected to the anode of triode 28. Normally triode 28 conducts' and the potential of point 36 is not high enough to provide sufficient current through meter M to balance the bias, when, however, signals above a certain low level are received, the A.G.C. voltage applied to the grid of the triode biasses it beyond cut-off and the potential of point 36.rises to a value arranged so that the current through meter M just balances the bias and so the meter gives true on or off course indications. Instead of a mechanical bias to the meter pointer, electrical bias from a battery 37 may be applied ; this method has the advantage that when proper " on-course '' signals are received there is no current flow through the meter M and so an automatic pilot as shown at 41 may be connected across it.

Title: Improvements in or relating to process and apparatus for separating and quenching oil products
IPC: C10G11/18
Filed: 1954-06-09
Abstract: <PICT:0751667/III/1> A hot gasiform stream effluent from a residium coking operation and containing entrained solids and oil vapours which have a tendency to polymerize at or slightly below the temperature of the stream is separated by passing the stream tangentially into a zone of circular cross-section to separate the solids, and by removing the stream of reduced solid content from the zone through an axial passageway into which fluid is introduced to quench the stream of reduced solid content below the polymerizing temperature.  The gasiform stream at 800 DEG -1500 DEG  F. and containing small particles of coke or another inert solid is fed to a cyclone 11 through the tangential inlet 13.  The separated solids are discharged by a "dip leg" 19 after passing through a further separator 17.  The stream of reduced solid content is removed from the cyclone through an outlet 21 of double walled construction. A quenching fluid, for example, a liquid hydro-carbon at a temperature of 500 DEG -700 DEG F. is sprayed into the outlet 21 by means of a vertically adjustable pipe 25 to quench the stream of reduced solid content to a temperature below 800 DEG F.
