Title: Signal receiver for discriminating signals
IPC: H04Q1/18
Filed: 1947-12-23
Abstract: 631,156. Electric -selective signalling systems. STANDARD TELEPHONES & CABLES, Ltd. Dec. 23, 1947, No. 33967. Convention date, May 7, 1943. [Class 40 (i)] [Also in Groups XXXIX and XL (c)] A receiver deriving signalling currents from any one of a number of A.C. sources mutually differing in intensity, frequency or phase, and arranged to operate a signalling device only when the received signal bears a predetermined relationship, e.g. identity, to a reference A.C. voltage, as described in Specification 565,785, comprises a discharge tube T1 which conducts when a signal voltage applied at Ss does not bear the prescribed relationship to a reference voltage applied at Sc and charges a condenser C to a voltage which prevents the discharge in a second tube T2. As shown, the signal and reference voltages are applied differentially via transformers Tr1, Tr2 with split secondary windings 2, 3, 5, 6 to each of two cathodes Ca1, Ca2 of a hot or cold cathode tube T1 in series with a steady negative voltage -150v. Thus, if different voltages are supplied to the transformers Tr1, Tr2 the peaks of the difference voltages in the secondaries will cause the cathodes Ca1, Ca2 to strike. The resulting unidirectional current in a resistance/capacity circuit C, Re3 lowers the potential of the anode and consequently of the control electrode Ce2 of a second hot or cold cathode tube T2 and prevents this tube from becoming conductive. If, however, the transformers Tr1, Tr2 are supplied with exactly similar voltages there will be no addition to the steady negative voltage applied to electrodes Ca1, Ca2, the first tube T1 will not be conductive, and the voltage on Ce2 will fall to zero. As a result, T2 fires and energizes relay SR. The first tube T1 may be replaced by one or two two-electrode tubes, and the differential transformers may be replaced by the transformer arrangement described in Specification 565,785.

Title: A cooling system for bar-shaped rolled stock
IPC: B21B43/02
Filed: 1966-07-28
Abstract: 1,133,969. Walking beam conveyers. SIEMAG SIEGENER MASCHINENBAU G.m.b.H. 28 July, 1966 [28 July, 1965], No. 33989/66. Heading B8A. [Also in Division B3] A cooling system for rolled bars includes a rack across which each bar is moved transversely and intermittently, the rack including sections positioned in different planes, with one section disposed in a water tank. Bars 1 from a roller conveyer 2 or chain conveyer 3 are moved by shifters 11 on to an hydraulically operated walking beam rack section 5. The rolling of the hot bars down the notched surfaces of the racks, during movement of the bars across the section, tends to straighten the bars. Hooked levers 8 are operated by cylinders 13, and levers 14 and 15, to shift the bars from rack section 5 to section 6, cams 18 preventing bars from falling from the section 5 when the levers 8 are in a lowered position. After passing across section 6, which comprises pivoted racks 6b and fixed racks 6a, similar levers 20 lift the bars on to a delivery shoot 10. The drives for the movable racks 5b, 6b may be combined, and oscillating as opposed to pivoting racks can be employed. The levers 8 can be replaced by an inclined rack conveyer, and the levers 20 can be dispensed with by causing the racks 6b to rise adjacent the shoot 10.

Title: Improvements in tubulous boilers
Inventor: ZOLLER RONALD ERNEST
IPC: F22B21/34
Filed: 1957-11-01
Abstract: 881,401. Water-tube steam boilers; superheaters. BABCOCK & WILCOX Ltd. Oct. 31, 1958 [Nov. 1, 1957], No. 34166/57. Classes 123(2) and 123(3) A water-tube boiler has an upright furnace chamber 2 with front and rear tube-lined walls 6, 8 and tube-lined side walls such as 10, the rear wall 8 at an upper portion 28 thereof being common to the furnace chamber and a downflow pass 30. Gases flow from the upper part of the furnace through a lateral pass 36 locating secondary superheaters 70, 72 into a turning space 46 and then downwardly in the pass 30. A vertical baffle 48, Fig. 2, divides the downpass 30 into a main pass 52 and a by-pass 50 the upper parts of which respectively contain primary superheater sections 54, 56 and economizer sections 78, 80 whilst the lower parts contain further economizer sections 74, 76 extending across both passes. Gas flow is proportioned between the main pass and the by-pass for controlling steam temperature by adjusting the outlet dampers 94, 96. The total downward extent of the main pass is reduced by dispensing with the dust hopper usually provided thereunder in order that the furnace burner windbox 110 may be located at the same side of the furnace as and below the bottom 98 of the main pass. The bottom 98 is inclined downwardly from the furnace chamber wall 28 and disposed sufficiently close to the lowermost economizer tube bank 74 to ensure that under all normal operating conditions a gas velocity adequate to sweep dust therefrom exists. A dust hopper 104 provided below the by-pass 50 has front and inner side walls which are inclined to clear the burner wind-box. In a modification a by-pass is provided on each side of the main pass.

Title: Improvements in or relating to a power operated stapling machine
IPC: A43D100/02
Filed: 1953-12-08
Abstract: 745,608. Stapling. TEXTILE MARKING MACHINE CO., Inc. Dec. 8, 1953 [Nov. 9, 1953], No. 34191/53. Class 89 (3). In a stapling machine in which a driver 27 is operated by power, each operation of the driver is initiated by manual movement of an anvil arm 13 to bring the anvil 15 against the stapler head 16, separation of the head and anvil during stapling being prevented by a pivoted latch 54 engaging pins 57 on the arm 13. As the arm 13 is moved to the position shown, the latch 54 is moved to the right and its hooked end 56 is raised to engage the pins 57. Movement of the latch operates through a lever 36, 37 which is pivoted at 38 on a lever arm 32, a link 42, a lever arm 45, a roller 49 and a twoarmed lever 50 to close a switch actuator 741 (not shown). This energizes a solenoid 76 to raise a plunger 78 which acts through a pin 48 on the lever arm 45, the link 42, the lever arm 37 and a roller 80 to actuate the driver plunger 26, the lever 36, 37 moving with the lever arm 32 about its pivot 35. The roller 49 is carried by a pivoted member 47 on the rear end of the lever 45 to permit lost motion during the return movement of the parts which occurs after the switch actuator has been opened by the roller entering a recess 82 in the lever 50. The stapler head 16 is removable from the machine frame 10 by movement of a lever 24 against a spring 23 to retract a retaining arm 21 and to disengage a hook 18 at the lower part of the head from a pin 14 by means of an arm 25.

Title: Improvements in or relating to a film gate for motion-picture film
IPC: G03B1/56
Filed: 1958-10-28
Abstract: 841,102. Kinematograph film gates. KODAK Ltd. Oct. 28,1958 [Nov. 1, 1957], No. 34445/58. Class 97(1) A film gate comprises an apertured plate 11 and a co-operating pressure pad 28, the whole gate being movable between a projection position (Fig. 5) in which the gate is held in engagement with a support, and a loading position (Fig. 6) in which the gate is tilted forward and displaced laterally with respect to the support, so that the film may be threaded into the gate without interference from the pull-down mechanism. The apertured plate 11 has a plurality of slots 24 which engage with guide lugs 25 formed on the support plate 26 when the gate is retracted into the projection position of Fig. 5. It is held in this position by the pressure pad 28, under the action of a spring-loaded plunger 37 forming part of the lens holder 36. Against one side of the apertured plate 11 bears the arms 18 of a U-shaped spring 19, under tension in this position. The film strip passes between the two parts of the gate, and is transported by a pull-down claw 23 engaging through a suitable slot in plate 11. When loading is required, the gate is pulled forward against the action of plunger 37 until the lugs 25 are disengaged from slots 24, upon which the gate is urged to one side by the spring arms 18, so that it occupies the tilted position shown in Fig. 6. Since it is now clear of the pull-down claw 23, the film 13 may be threaded freely into the gate, until it bears against pins 33 carried by plate 11. Continued gentle pressure on the film against these pins moves the gate back against the action of the spring arms 18, until the slots 24 are again in register with lugs 25, when the plunger 37 once more presses the gate back into the Fig. 5 position.

Filed: 1966-08-02
Abstract: 1,159,705. Separating gases. UNIVERSAL OIL PRODUCTS CO. 2 Aug., 1966, No. 34553/66. Heading B1L. [Also in Division C5] In cyclic systems for the continuous separation of components of fluid mixtures in which the fluid stream is continuously circulated through a mass of sorbent, into which system in succession the feed stream is injected, raffinate is withdrawn, desorbent is injected and desorbed sorbate is withdrawn, and in which systems a continuous or intermittent relative motion is maintained between the mass of sorbent and the feed inlet point, which relative motion is countercurrent to the flow of the fluid stream through the system, a raffinatetype compound which is however readily separable from the raffinate, e.g. by distillation, is introduced to the system at a point upstream of the feed inlet but downstream of the desorbed sorbate outlet, whereby feedstock is thoroughly flushed from the countercurrently flowing stream of sorbent particles passing upstream to the sorbate-recovery zone of the cycle. In a first embodiment (see Fig. 1, not shown), the various inlet and outlet points are fixed while the mass of sorbent passes continuously and in succession through the treatment zones; in a second embodiment (see Fig. 2, not shown) however, a fixed mass of sorbent is divided into a large number of unit beds, intermittent relative motion between the mass of sorbent and the various inlet and outlet points being achieved by successively switching these points through the sequence of unit beds. In the examples, mixtures of normal and branched chain hexanes; n-hexane and cyclohexane; and aromatics and non-aromatics were separated. In the latter separation, charcoal was used as sorbent, steam as desorbent for the aromatics and n-pentane as the raffinabe-type compound; in the two former separations, calcium aluminosilicate molecular sieve was used as sorbent, n-butane as the desorbent for the n-hexane, and iso-butane as the raffinate-type compound. Other stated applications include the drying of nitrogen or air, and the removal of amines, mercaptans, phenols or thiophene from hydrocarbon fractions.
