Patent GB-504884-A (GB)
Abstract: 504,884. Calculating-apparatus. HELLGREN, G. H. Aug. 20, 1938, No. 24583. Convention date, Aug. 21, 1937. [Class 106 (i)] In a calculating-machine comprising a register 17, actuator racks 15 and differential members 14 co-operating with stop means 76, supporting means 16 for the differential members move away relative to the stop means during an operative cycle, after the differential members have been set. The machine is actuated by an arm 12, Fig. 4, which is pulled forward until a projection 34 thereon engages pin 35, and then released. An arm 21 on the shaft 11 is linked by a member 22 to a plate 24 carrying rollers 37 and 38, the former engaging a recess 39 in a bar 40 pivoted to a pivoted bar 43 and moving the bar 40 to the left at the commencement of the cycle. The bar 40 pushes the totalizer 17 out of engagement with racks 15, and a bar 51 pivoted at 42 and linked by a bar 52 to a bell-crank 54, causes a frame 16, 69, to be lowered to co-operate with setting pins 76. These are set by keys 1, Fig. 1, which rock bell-cranks 116 having pointed noses 117 which lift corresponding pins 76. A plate 120 has a ridge 121 bearing on all the bell-cranks 116 and a projection 123 co-operating with the " nine " setting pins which are in the path of a stop 125, so acting as an escapement device. A series of bars 14, Figs. 1 and 4, with projections 74 are slidable in the frame 16, 69, and when the lower end of plate 24, Fig. 4, engages a pin 30 on a sector plate 31, a link 58 rotates V -shaped plates 60 about a shaft 260, and springs 64 on a cross-bar 62 pull the racks 15 about the shaft 260, which racks, being linked at 66 to the bar 14, are set by the pins 76. The roller 38 now lifts the bar 40 and disengages the roller 37 therefrom, a projection 49 being lifted behind a stop 50. At the end of the forward stroke the roller 38 engages the notch 39 and as the bar 40 is pulled rearwardly by the spring 27 the totalizer wheels are engaged with the racks 15 and the frame 16, 69, is raised from the setting pin carriage by the bell-crank 54, the bars 14 being held by pawls 78. A linkage (not shown) operated from the shaft 25 serves to return the setting-pin carriage. New factors may now be set up in the keyboard without interfering with the final operations of the machine. The subtract key 140, Fig. 4, when depressed rocks a lever 145 linked by a spring 148 to the totalizer frame 131 pivoted at 130, but a projection 150 thereon is held by a pin 151 on a V-shaped lever 152, 153, the arm 153 being engaged by a pin 155 on an arm 156 towards the end of the forward stroke. Hence, the actual change-over of the totalizer initiated by the key 140, takes place at the desired stage in the cycle. Applied to a multiple-bank keyboard machine, the movements of the differential members 167, Fig. 11, are magnified by levers 166 linked to the bars 14. The bars 167 are movable vertically under the control of the bell-crank 54. Specification 395,474 is referred to.

Abstract: 1,194,096. Bearings; lubricating. ELECTRICITE DE FRANCE (Service National). 24 Oct., 1968 [22 Nov., 1967], No. 50514/68. Heading F2A. A method for the production of a self-lubricating component assembly having interengaging surfaces between which there are interacting friction forces during operation in a hot state and in a gaseous atmosphere comprising, depositing an adherent coating of calcium fluoride on one interengaging surface; depositing an adherent coating on the other interengaging surface, the deposit being harder than said surface so that it is not scored at low temperature by the calcium fluoride coating; and applying graphite to at least one of said surfaces. The calcium fluoride is in a powdered state and is sprayed on to a hardened component such as quench-hardened steel; the surface of the component having been prepared by a sand-blasting process. After the deposition of the calcium fluoride, the component is annealed. The friction surface of the interacting component must have a greater hardness than the friction surface of the calcium fluoride and may comprise a sprayed-on coating of alumina, carbides or steels, for example, and is polished. The graphite is applied by a rubbing operation.

Title: Indication related to the percentage cell volume in a conductive liquid
IPC: G01N15/06
Filed: 1970-10-28
Abstract: 1316473 Particle analysis TECHNICON INSTRUMENTS CORP 28 Oct 1970 [1 Dec 1969] 51187/70 Heading G1N The invention relates to measuring the concentration of particles in a conducting liquid with COMPENSATION for VARIABLE CONDUCTANCE of the CARRIER liquid by correspondingly varying the feed-back to an operational amplifier. The measurement is directed to the hematocrit of blood samples. In batch-sequential-tester Fig. 1, whole blood and the corresponding plasma samples on turntable 20 are fed by peristaltic pump 38 to cells 60, 61 with suitable washing cycles between samples. The conductance signal Gb from the whole blood cell 60 is applied to the input of operational amplifier 74 with feed-back Gp through the plasma conductance cell 61 whereby an output signal Gb/Gp Î E (the oscillator voltage) is produced. This is added to the oscillator voltage at point c and subtracted (due to inverter 106) at point e and the ratio of these summed signals indicated by a self balancing potentiometer type recorder. This ratio H = 1 - Gb/Gp / 1 + Gb/Gp gives the required hematocrit value. CALIBRATION for particle shape may be introduced by a preset potentiometer 116, introducing a constant factor. Alternatively an average plasma conductance may be assumed and compensation for its variation of conductance with TEMPERATURE provided by a resistance network including a thermistor in the amplifier feed-back path (instead of a plasma sample).

Abstract: 1474044 Heat setting blown oriented containers IMPERIAL CHEMICAL INDUSTRIES Ltd 24 Nov 1975 [3 Dec 1974] 52230/74 Heading B5A Blown oriented plastics containers are heat set against distortion during subsequent use by forcing them by gas under pressure against the walls of a mould heated to a temperature at which crystallization occurs, and cooling them in the mould whilst maintaining the gas pressure. In one embodiment the container is stretched and blown in a mould and then cooled in that mould whilst retaining pressure by the blowing gas. In a second embodiment the blowing gas is replaced by a liquid to be packaged, which liquid effects the cooling. In the described embodiment, a parison of polyethylene terephthalate 1 preheated to 95 C. is longitudinally stretched by a plunger 10, 11 slidable within a mandrel 3. The plunger has at its rear end a piston slidable in a cylinder 17  and at an intermediate portion a collar 12 slidable in an enlarged bore within the mandrel. The mandrel itself is slidable in a piston like manner in a cylinder 9 to which compressed carbon dioxide is fed. The plunger is provided with flats to allow leakage of the gas into the parison and a conduit 23 feeding carbonated liquid to be packaged is provided. In operation compressed gas is admitted to cylinder 9 to forward the mandrel to its lowermost position and to force the plunger downwardly to stretch the parison (see Fig. 2). Gas leaking past the plunger blows the stretched parison into the halves 6a, 6b of a split mould heated to 200 C. by circulating oil. Subsequently the mandrel and the plunger are completely withdrawn from the mould by the cylinder 17 (Fig. 4) and the liquid to be packaged introduced into the blown container. At the same time a valve 24 is operated to vent the gas from the container. After the container has cooled, the mould halves are withdrawn, and the filled container removed by gripper plates to a capping station.
