Title: Improvements in or relating to methods of and apparatus for reducing oxides such as metallic ores
IPC: C21B13/00
Filed: 1941-02-20
Abstract: 547,363. Reducing ores; furnaces. WILSON, L. Feb. 20, 1941, No. 2337. Convention date, March 30, 1940: [Classes 72 and 82 (i)] [Also in Group XII] Oxides, particularly iron ores, are reduced by discharging them in finely divided form in a freely falling shower through a reducing atmosphere in a pre-heated reaction chamber, the supply of heat being discontinued before the admission of the charge and the reduced product being collected at the bottom of the chamber. The reducing atmosphere is maintained by admission of reducing gas, or by vaporization of hydrocarbon oil, or by admitting finely divided solid carbonaceous reducing agent in admixture with the oxides. The charge may be conveyed to the top of the chamber by a preheated air stream. The apparatus shown comprises a tower 10 having burners 13, a feed hopper 18, tilting hearth 31, and discharge hopper 36. The feeder comprises a funnel 19, Fig. 9, surmounted by discs 21, 24 having ports 22, 28 between which moves a compartmented rotor 25 which passes the material from a supply duct 29 to the port 22 and funnel 19. When a charge of material has been treated, the hearth 31 is tilted to discharge the metal through the hopper 36 into a vessel 39 which has been brought up to make gas-tight connection with the hopper 36. In a modification, twin reaction towers are operated alternately, each tower being reheated between successive operations, the apparatus comprising also regenerators for supplying hot air to the tower being heated and for combustion with the combustible gas formed in the tower which is in operation.

Title: Improvements in and relating to reciprocating liquid pressure pumps
IPC: F04B53/00
Filed: 1938-01-25
Abstract: 486,740. Reciprocating pumps. JUNKERS FLUGZEUG - UND - MOTORENWERKE AKT.-GES. Jan. 25,1938, No. 2385. Convention. date, Jan. 27, 1937. [Class 102 (i)] Oscillating cylinder pumps ; lubricating reservoirs.-Comprises means for preventing the return flow of liquid from a crank case containing oil under pressure, and means for compensating for change of volume in the crank case due to the piston motion of benzine &c. pumps connected with the crank case. The pump cylinders oscillate, and the pistons are connected to opposed cranks on a shaft 4. The inlet and outlet passages 11, 12 are controlled by the cylinders. The side member 3 of the casing is provided with an extension 16 containing a chamber connected to the force-feed oil pipe 20 and with two passages 21, 22, leading to the crank case 10. A spring- pressed piston 25 mounted in the casing, controls the passage 22, and has a seat 26 which may engage a seat 31 around the outlet 18. When the crank case is empty, the piston 25 closes the passage 18. When pressure oil is forced into the passage 18, the piston 25 is moved to open the passage 23 and the crank case is filled. If during the running of the pump the crank-case pressure increases, liquid is forced back into the pipe 20, the piston 25 is raised and the passage 22 is closed. A reduction of crank-case capacity is balanced by a downmovement of the piston 25.

Title: Information transmission systems
IPC: H04Q9/14
Filed: 1971-01-18
Abstract: 1332520 Signalling over power circuits TOKYO ELECTRIC POWER CO and FUJITSU Ltd 18 Jan 1971 [17 Jan 1970] 2416/71 Heading H4R Binary information is transmitted over a line carrying an A.C. voltage, e.g. a power line, as a pulse of a higher frequency signal which pulse is synchronized with one part of the A.C. cycle, e.g. the positive half cycle, to denote a binary "1" and with another part of the A.C. cycle, e.g. the negative half cycle, to denote a binary "0". As described the signal from an oscillator OSC, Fig. 4, is applied by a switching circuit, comprising rectifiers D1 to D4, to an A.C. power line F. In one position of the switch SW the oscillator is connected for the positive half cycle of the A.C. waveform and in the other position the oscillator is connected for the negative half cycle to superimpose the oscillator output on the A.C. power line voltage. In the receiver, Fig. 5, the signal is applied via amplifier 1, provided with a.g.c. a band pass filter tuned to the signalling frequency, and a second amplifier 2, to the detector DET. The output from the detector is applied to the inputs of shift registers Bα1 to Bα4 and B# 1  to B# 4 , the first shift register effectively samples and shifts the signalling information at the centre of the positive half cycle of the A.C. waveform, as determined by the Schmitt trigger SCH and delay unit DL1 and differentiator D1F1, while the register B# 1  to B# 4  samples and shifts the signalling information at the centre of the negative half cycle of the A.C., determined by SCH, DL2, D1F2. The resulting signals in the registers are compared by a checking logic circuit CC, shown in Fig. 6, which only produces a validating output CK when the input information is consistent over four cycles of the A.C. waveform and signals are present during those four cycles only on one half cycle and not on the other.

Filed: 1972-01-19
Abstract: 1375756 Accurately positioning suspended loads CONRAD STORK BV 19 Jan 1972 [29 Jan 1971] 2555/72 Heading B8B As shown in Fig. 1 a container 9 to be accurately positioned is suspended on hoisting cables 5 from a trolley 2 on a bridge crane 1. The cables 5 pass from a hoisting drum 4 over sheaves 6 to attachment points 8 on the trolley 2. Positioning wires 11 pass from lifting frame 7 over sheaves 12 to a drum 10 driven by a constant couple to maintain the wires 11 continuously tensioned. Eccentric loading due to wind forces or off-centre centre of gravity cause different stresses to occur in the cables 5 and in the wires 11. These differences cause differential elongation of the various lengths of wire and cable. The different stresses in the cables 5 are sensed by measuring systems incorporated in the attachment points 8 and result in movement of these points to compensate for the differential elongation they cause. Differential stresses in the positioning wires 11 are sensed by measuring devices 15 which provide a signal to a control device 16, this acts to move rod 14 carrying pivoted rods 13 with sheaves 12 in such a direction as to compensate for the differential elongation caused by the stresses. The response of the measuring devices at 8 and 15 may be modified to allow for the varying distance of the load 9 from the trolley 2, rotation of the hoisting drum 4 and of the drum 10 may be used for this purpose. Fig. 3 shows an embodiment wherein separate positioning wires are not required: two cables 24 from each of four coupled drums 23 pass over respective sheaves 25 on trolley 22 and sheaves 28 on lifting frame 27 to attachment points 29 on the trolley 22 where differing loads causing differences in elongation in the various cables 24 are sensed by a load measuring box (30), Fig. 4 (not shown), and are compensated by a stepping motor (31) driving a mechanism to tilt a lever (33) carrying the box (30).

Title: Improvements relating to machines for making glass bottles, jars and like articles
IPC: C03B35/12
Filed: 1942-03-02
Abstract: 552,103. Glass manufacture. CANNING TOWN GLASS WORKS, Ltd., WATSON, P. J., and HONEY, F. H. March 2, 1942, No. 2726. [Class 56] A device for removing the finished articles from a machine for making glass bottles comprises a carrier which is rotated in a horizontal plane and is provided with sets of spring- loaded jaws that pass in succession over an open finishing mould and grasp the article thereon, and a cam for opening the jaws to release the bottles as they arrive at the delivery point. The device comprises a disc 5, Fig. 3, adjustably secured to a vertical shaft 3 which is rotated in synchronism with the mould table of the forming machine. A carrier 10 rests on the disc 5 and is rotated through the medium of spring-pressed balls 8 which engage in pockets on the carrier, the connection forming an overload release mechanism. Radial arms 11 are adjustably attached to the carrier 10 and each carries at its outer end a pair of jaws 21, Fig. 2, which slide in a guideway and are drawn towards one another by a spring 22. The jaws resiliently grip the formed articles and remove them from the open moulds, and when each gripper arrives at the delivery point, a stationary cam 31 enters between rollers 24 secured to the jaws 21, thus separating the jaws and releasing the finished article. In a modified construction, the jaws are pivoted at the ends of the arms instead of being slidable in guides.

Title: Improvements in or relating to thermostats
IPC: H01H37/52
Filed: 1963-01-22
Abstract: 1,014,212. Thermal switches. G.-V. CONTROLS Inc. Jan. 22, 1963 [Jan. 22, 1962], No. 2737/63. Heading H2B. In an electric thermostat, a lever 60, pivoted at one end on an extension 43 of a bimetallic element 41 and also pivoted on a post 52 extending from a second bimetallic element 51, is rotated as the bimetallic elements 41, 51 move, as shown by arrows in the Figure, with a rise in temperature in the surrounding medium so that a glass ball 64 on the end of the lever 60 pushes against a spring arm 18 and opens contacts 22, 21 held by the arms 18, 17 respectively. The spring arms 17, 18 are spot welded to pins 7, 8 which are formed at their tops into soldering lugs 9, 10. A screw 19 is provided for manual adjustment of fixed contact 21. The bimetallic elements 41, 51 are attached in a stack 30 with spacers 31, 32, by means of a thermally conductive rivet 33 to the thermostat housing. When the temperature increases outside the housing, its rise is communicated through frame 1, walls 5 and stack 30 to the elements 41, 51 which have been arranged so that element 41 deflects downwardly to depress the pivoted end of the lever 60 and at the same time, the second element 51 deflects upwardly, which closes the gap between the top of the post 52 and lever 60 and eventually rapidly turns the lever 60 and opens the contacts abruptly. A spring 53 on the post 52 supports the lever 60 until the element 51 is deflected sufficiently for the post to pivot the lever. In other embodiments the contacts may be " normally open ", Fig. 6 (not shown) in which the bimetallic elements deflect in the opposite sense. Alternatively the elements may both deflect in the same direction, with one thermally insulated from the rivet and housing, Figs. 7 and 8 (not shown) so that a sudden increase in temperature opens the contacts rapidly. In the embodiment shown in Fig. 8 the change in curvature of the first element for a given temperature change is less than that of the second element so that the contacts will be operated at a certain temperature if the housing temperature changes gradually and at a different temperature if the housing temperature changes suddenly. In Fig. 9 (not shown), the bimetallic elements are bonded to a single layer of metal which is fixed in the stack 30. Specification 1,014,211 is referred to.

Title: Control device for a monitor supervising a patient
IPC: A61M5/00
Filed: 1975-01-22
Abstract: 1459972 Applying medicament D KAMEN 22 Jan 1975 [11 May 1974] 2794/75 Heading A5R [Also in Division G3] Control apparatus includes a first timer which initiates an operation after a first predetermined time period and also starts a second timer which inhibits further operation of the first timer until a second set time elapses. The system shown is used to monitor the condition of a patient and automatically to inject a medicament if the patient's condition deteriorates, and by the use of the inhibiting set time to allow the medicament time to be effective. The monitor 12 senses a change in the monitored condition, e.g. heart beat, blood pressure, and energises generator 24 to produce a voltage which charges a capacitor in timer 26. Sufficient time delay is set into timer 26 so that transient changes in the monitored condition, caused for example by a position change, do not cause medication to be administered unnecessarily. When timer 26 times out it outputs a signal to second timer 28 and to the automatic syringe 18 which administers medication. Timer 28 sends a signal on line 40 to the first timer control 30 which causes a short-circuit element, e.g. a triac, to be connected across the timer capacitor thus inhibiting operation of the timer until the second timer times out.

Filed: 1974-01-21
Abstract: 1414765 Identifying objects HONEYWELL INFORMATION SYSTEMS Inc 21 Jan 1974 [19 Jan 1973] 02835/74 Headings G4H and G4M The invention relates to the correlation of an identified bulk quantity with the analysis result of a test sample taken from that quantity, e.g. in a clinical chemistry laboratory. Random numbers x, y, z are associated with a patient 10, a sample container 15 and one or more subsample containers 23 respectively. On admission to hospital, the patient's personal details are entered into a memory 13 together with his allotted number x. The patient is given a wristband to which is attached a machinereadable label 12 bearing his number x; the label may be in the form of an apertured ring as in Fig. 3, and is of the same form as the labels 16, 24 attached to containers 15, 23. When a sample is taken from the patient, labels 12, 16 are read by a portable reader 17, Figs. 4-7 (not shown), and stored in a temporary memory 20, the numbers x, y being subsequently transferred to the memory 13. Container 15 is then taken to a transfer station 22 where the sample is distributed among subsample containers 24 and analysed 27, numbers y, z on labels 16, 24 being read and stored in memory 13. After analysis, the container label number z is stored with the results for that subsample. Logic 32 associated with memory 13 then operates to associate the patient data with his test results, both of which are printed out. Memory 13 and logic 32 may be part of the hospital computer, when the pairs of random numbers are stored by indirect addressing. Reader 17 contains magnetic cores whose flux linkage depends on whether an aperture is present or not in each bit location on the label. The transfer station 22 and analyser 27 may be automated, a description of suitable Honeywell equipment being provided with reference to Figs. 9-14 (not shown).
