Abstract: 1,221,007. Roller conveyers. P. PATIN. 19 Nov., 1968 [20 Nov., 1967], No. 54784/68. Heading B8A. In a roller conveyer for passengers or packages the speed of the load-bearing rollers varies substantially steplessly. In Fig. 1 each span of the four conveyer spans shown comprises a row of bearing rollers 1 rotated by a row of drive rollers 2 which are rotated by belts 5, 6 running on drums 7a, 8a, 7b, 8b. The drums 7 are secure with shafts 9 but the drums 8 are rotatable on the shafts 9 and may run at a different speed from the drums 7. Drive pulleys 14 for the shafts 9 are stepped so that consecutive shafts run at different speeds as do consecutive belts 5, 6. A, B indicate adjacent compartments of the conveyer. Figs. 2, 4 show how the rollers 1, 2 are located in gratings 3, 4 which have recesses 19 to receive journals of the rollers. In Fig. 3, roller 2 has a portion 21 in driving contact with the belt 5 and has sections 22, 23 which respectively engage a section 25 of the preceding bearing roller 1 and the section 25 of the following roller 1a. The diameter of the sections 21 of the drive rollers 2 varies substantially steplessly from one roller to the next and accordingly, the peripheral speeds of the bearing rollers 1 in any single compartment also increase steplessly. In the Fig. 1 construction, the last bearing roller 1 of one compartment runs at almost the same speed as the first bearing roller of the next compartment. For a curved section of conveyer, the rollers may be slightly conical, Fig. 7 (not shown). In Fig. 8 a main constant speed or variable speed conveyer 28 is fed by a variable speed conveyer 27 which picks up passengers at walking speed and gradually accelerates them to the main conveyer speed. There may be two convergent accesses at the entry of a conveyer and two divergent exits at the end of the conveyer.

Filed: 1967-12-07
Abstract: 1,222,368. Fluid logic devices. BRITISH AIRCRAFT CORP. Ltd. 5 Dec., 1968 [7 Dec., 1967], No. 55686/67. Heading G4P. A binary fluidic logic device which may form one stage of a shift register or counter comprises elements A, B, C respectively having input 10 and outputs 12, 14; input 27 and outputs 28, 30; input 34 and outputs 36, 38. Element A is monostable. A pulse at 10 normally flows to 12, but in the presence of a control signal at 16 flows to 14. Element B is bi-stable. Element C is monostable and receives at input 34 a signal whose presence or absence represents 1 or 0. In the absence of a control signal at 24 the input signal passes to output 36. When employed as one stage of a shift register, if there is an O-bit signal at input 34 a shift pulse at 10 passes via 12 into 24 and into 26 to cause the power jet of bi-stable B to exit at output 30 to represent a O-bit. Output 30 is connected to the input 34 of the next stage of the register. If there is a 1-bit signal at 34 the shift pulse at 10 leaves A by 14, part flowing through 20 and 16 to maintain bias on the shift pulse and part flowing to 22 to cause the power jet of bi-stable B to exit at output 28, the lack of flow at 30 representing a 1-bit. Passages Y, Z shown in skeleton may be used to set all bi-stables B in the register to "O" on applying a pulse to the Z passages, or to reset them to "1" by pulsing the Y passages. When employed as a stage in a counter input 34 of element C is connected to the output 30 of the element B. Successive input pulses at 10 set bi-stable B alternately to 1 and 0, the bi-stable being coupled by meansnot shown to the input 10 of the next stage.

In an ultrasonic tester of the pulse echo type having separate transmit and receive transducers, the latter are arranged so that their active faces are inclined to the surface of the body to be tested and are inclined relative to each other in a plane parallel to said surface. This arrangement is said to eliminate surface waves and hence improve signal/noise ratio when tests are being made on a (hot) metal object which includes a solid/liquid boundary just below its surface. The piezo-electric transducers 4, 5 are embedded in a block of resin 6 and may be damped by backing blocks 10, 11 composed of resin, powdered tungsten and powdered rubber. The transducers are separated by a cork screen M. A pipe 8 extends through the block for allowing passage of a coupling liquid to that face of the block which overlies the test object. The angles of inclination to the test body and to each other of the transducers may be variable.

The pH is preferably adjusted to a value in the range 6 to 12 and adjustment is suitably achieved by adding to the aqueous solution NaOH, KOH, NH 4 OH, sodium- or potassium-carbonate or bicarbonate, barium hydroxide or calcium hydroxide, or a mixture of two or more thereof. If the untreated aqueous solution has a too basic pH the pH may be reduced to a value in the preferred range of 6 to 12 by addition of an acid, e.g. hydrochloric, sulphuric, formic, acetic or citric acid or a mixture thereof. Several water-soluble organic solvents are specified, the preferred solvents being acetone, tert.-butyl alcohol, isopropyl alcohol and ethyl alcohol. When the solvent added is n-propyl alcohol, isopropyl alcohol, tert.-butyl alcohol, acetone, dioxane, or tetrahydrofuran or a mixture of two or more thereof the solution may be treated after removal of the precipitated impurities by an additional amount of the same solvent to isolate the CAMP or deCAMP and the resulting solution allowed to stand at from 0 to 25 C. for 16 to 48 hours to form crystals which are then collected. In another method of isolation of the CAMP or deCAMP the purified solution, after removal of the precipitated impurities, is adjusted to a pH of 3 or less, e.g. by addition of one of the above specified acids, and maintained at 0 to 25 C. for 6 to 24 hours to allow the CAMP or deCAMP to crystallize and the crystals collected. The solutions to be purified may be obtained by a fermentation method, synthetic method, enzymatic method or living body extraction method for the production of CAMP or deCAMP.
Patent GB-568601-A (GB)
Abstract: 568,601. Temperature alarms. LANNGE, B. A. April 16, 1943, No. 6106. Convention date, Feb. 15. [Class 40 (i)] [Also in Groups XXI, XXX, XXXVI and XXXVII] Each of a number of bearings, e.g. of the wheel axles of a train, is provided with a temperature - sensitive switching device connected to a central station over a circuit common to a number of such devices and the position of a faulty bearing is indicated by a resistancemeasuring operation. In one arrangement, Fig. 1, current normally flows through the temperature-responsive switches 1 in series with a switch-controlling magnet 9a at a central point and an overheated bearing causes one of these first to interrupt this circuit and subsequently to complete a circuit over a wire 4 short-circuiting all the protective circuit on the side remote from the central point. Release of magnet 9a completes a lamp-and-bell circuit, this circuit being held closed by a latch 10 even when 9a is reoperated. The location of the faulty bearing is indicated by a galvanometer 15 when the switch 6 is moved to the dotted position. In modified systems two loops are provided for the near- and off-side bearings respectively and with individual or common return leads. Instead of the galvanometer 15 a Wheatstone's bridge system can be used. In another system a lamp is extinguished and a bell sounded when one of the bearing switches operates. In another system, Fig. 6, separate lines are provided for the near- and off-side bearings and are not normally connected together but are bridged at the faulty bearing to provide current for operating the alarm devices and, when switch 6 is thrown, the resistance-measuring instrument 15. Construction of switching devices. Each of these comprises a casing which is screwed into the bearing. Contacts are made and in some cases broken in response to an excessive rise in temperature either by the agency of a bimetallic member or by fusible metal. Construction of plug-coupling. The protective current is extended from coach to coach by fiexible cables coupled by the device shown in Fig. 9. Each conductor of the cable is terminated by a spring 31 connected as shown to a spring 30 and mounted on a plug part of insulating material. When the coupling members are separated, the springs 31 engage a plate 32 which may be individual or may be common to two or more of them so that the protective circuit is completed again automatically when interrupted by the separation of the coaches.

A cut tobacco feeder for feeding an even layer of tobacco on to a conveyer band, comprises a first conveyer band forming the bottom of a storage chamber and so running under the lower end of an inclined second conveyer band which runs upwards from the first band and forms one side of the chamber, such that, in use, a first layer of tobacco remains on the first band, the second band having needles on its surface, at least one levelling roller positioned above the upper part of the second band to level the tobacco thereon, and a roller adjacent the top of the second band for picking up tobacco so as to cause this tobacco to fall on the first layer to form a second layer. Figure 1 is a sectional view of the feeder wherein first conveyer 3 carries tobacco along and under the inclined conveyer 7, which conveyer carries tobacco upward. A thrusting roller 10 levels the tobacco on this band and breaks up any lumps, and thus tobacco passes under a levelling roller 11 before being picked off this conveyer by roller 13. The picked-off tobacco falls into shoot 14 and then forms a second layer on top of the first layer on band 3. These layers may be removed from band 3 by suction means.

Abstract: 1285635 Making metal laminates TEXAS INSTRUMENTS Inc 25 Nov 1969 [30 Dec 1968] 57685/69 Heading B3A [Also in Division F2] A method of making a metal laminate consisting of a relatively hard metal layer sandwiched between relatively softer metal layers comprises contacting the surfaces of the hard metal layer with respective surfaces of a pair of softer metal layers, a first squeezing operation to form limited metallurgical bonding between the layers, heating to increase the bonding and heating to anneal the layers of the laminate, and a second squeezing operation on the laminate while under substantial tensile force with a substantial reduction. The first squeezing operation produces a reduction of between 50 and 80%. The heating steps may be carried out simultaneously or, particularly when the laminate consists of stainless steel sandwiched between low carbon steel layers, the first heating may increase the bonding and anneal the outer layers and a second heating anneal the inner layer. The second squeezing is preferably done with the laminate under a tensile force greater than 20,000 lb. per sq. inch. In examples low carbon steel is bonded to stainless steel by first cleaning the surfaces of the layers squeezing them together with a 67% reduction to form a laminate. The heating is either heating at 1250 F. for 3 hrs. to increase bonding and anneal the low carbon steel layers then annealing the stainless steel layer at 1900 F. for 1 to 4 mins., preferably about 2 mins., or heating at 750 to 950 F. for several hours to increase the bonding then annealing all the layers at 1900 F. for 1 to 4 mins., preferably about 2 mins., or heating at 1950 F. for 1 to 3 hrs. to increase bonding and anneal all the layers. The laminate is then passed through a roll squeezing mill three times with reductions of 45%; 39% and 23% under front and back tensions of 9000 and 23,500 lb./sq. inch; 12,000 and 25,000 lb./sq. inch; and 13,000 and 25,000 lb./sq. inch respectively. One or two roll passes not under tension may be used to bring the laminate to its desired final gauge and it is then annealed at 1950 F. for 90 sees. The laminate is then slit and may later be coated with copper. The hard metal layer preferably forms 10% of the final thickness of the laminate.
