Abstract: 1,206,183. Conveyer system. SI HANDLING SYSTEMS Inc. 21 Sept. 1967, No. 43076/67. Heading B7L. A tow truck system comprises a main slot 14, Fig. 1, e.g. in a floor 12; a self-propelled tractor truck 20; guide means in the form of a raisable and lowerable guide pin 50, Fig. 2, on the tractor extending into the slot 14; an elongated tow line, e.g. a chain 80, of finite length, in the slot and substantially shorter than the length of the slot; means, e.g. a tow pin 61, on the rear of the tractor for connecting the latter to a front portion 79 of the tow line 80; drive transmitting means 94, 96, Fig. 5, spaced at intervals along the tow line; and at least one tow truck, e.g. 20<SP>1</SP>, having guide means, e.g. in the form of a guide pin 50<SP>1</SP> extending into the slot 14 and coupled to a drive transmitting means 94, 96. In an alternative embodiment the tractor guide pin 50 may engage the portion 79 of the chain. Shunt slots, e.g. 16, 18 are connected to the slot 14 through switch plates 114, 120. Truck guide pins, e.g. 50<SP>1</SP>, can move laterally in slots 90 in the chain 80 for disconnection therefrom. The tractor 20 may be diverted to the slot 16 by a selectively placed trip pin 66 on the tractor engaging a floor actuator 110 which is connected in known manner to the switch 114. The latter is reset by the tractor guide pin subsequently engaging a lever 117 in the slot 16. A towed truck, e.g. 20<SP>1</SP>, may be disconnected from the tow chain 80 and diverted down a slot, e.g. 18, by a selectively placed trip rod 66<SP>1</SP> on the tow truck 20<SP>1</SP> engaging a floor actuator 116 connected to the switch plate 120. The latter has an ear 121 operable by the diverted truck 20<SP>1</SP>, which is pushed by a following truck on the chain, to reset the switch plate 120. The tractor has a movable bumper 72 which on meeting an obstruction can operate a switch 78, in an electric circuit for a motor or motors 31 driven from a battery 30, to stop the motor or motors. The bumper can also lift the guide pin 50 and operate a switch 123 in the motor circuit.

Title: Method of reducing iron oxide
Inventor: KEITH PERCIVAL CLEVELAND
IPC: C21B13/00
Filed: 1965-10-18
Abstract: Iron oxide is reduced with hydrogen at a pressure greater than 200 p.s.i. and temperature less than 1400 DEG F. in a series of superposed vertically spaced fluidized bed reaction zones, the hydrogen being introduced into each bed at a controlled velocity through uniformly spaced nozzles to introduce a pressure drop between the beds of 1 to 5 p.s.i. The nozzles are so constructed that 20-30% in each zone of them introduce gas at a level higher than the remainder.  At intervals the whole of each bed is caused to fall to the next lower bed. It is desirable to have a series of vertical baffles in each reaction zone; these are preferably formed by heat exchange elements, the exchange medium being the hydrogen to be subsequently used for reduction.

Abstract: 1,100,789. Making springs. EKO - KONSTRUKTION AKTIEBOLAG. 19 Oct., 1965 No. 44342/65. Headings B3A and B3N. Apparatus for screwing together the different diameter ends of a helical spring to form a ring, comprises at least one head 1b Fig. 1, with rotatable rollers 8a, 8b, 9, for gripping one end of the spring to screw it into the other end, and at least one similar head, for holding the other end of the spring in coaxial end to end engagement with the first end of the spring. Each of the heads comprises a part 2 pivoted to a second part 3 at 5 against a spring 6. Wheels 8a, 8b may have teeth for engaging the work, and are rotatably mounted in part 2, and wheel 9 is rotatably mounted in part 3. Wheels 8a, 8b have central reduced diameter gear portions which mesh with a gear .10 and a friction brake 11 acts on gear 10. Each head has a stub shaft 13 which is pivotably carried by an arm 15, Fig. 3, which arm consists of two axially displaceable portions, one for each head, a pin 14 being provided in the head for causing the pivotal movement. Three arms 15 constitute a rotor, and cam paths 16, 17, 19, 20, 23, and 24 are provided. In operation, with the rotor moving in the direction B a helical spring C is placed in a holder 18, with the ends to be joined pointing upwardly. Cam path 16 pivots heads la, 1b into the position shown at the top of Fig. 3, and cam paths 17 co-operate with pins 14 to open the heads so that the ends of the spring are located between wheels 8a, 8b, 9. The heads grip the ends of the spring, and cam path 16 pivots the heads, to thus align the ends of the spring. Head la passes under cam path 19 which rotates gear 10 and twists the spring end in the unscrewing direction, the other end of the spring being held against twisting by the brake 11. Head 1b passes under cam path 20 and this spring end is twisted in the screwing up direction, with the other end of the spring being held by its brake. The heads are brought together by relative axial movement of the portions of arm 15, and the spring ends are screwed together. A part of arm 15 is actuated by cam path 23, and the heads are moved apart, so as to stretch the spring, and test the joint. The heads pass between cam paths 24, which co-operate with pins 14 to open the heads, the spring is released, and is removed by an oscillating arm.

Abstract: 1,167,317. Electro-chemical analysis. L.C. CLARK. Oct.6, 1966 [Oct.8, 1965], No.44769/66. Heading G1N. Apparatus for electro-chemical analysis of an inactive substance e.g. blood glucose, in the presence of an interfering electro-chemically active substance e.g. ascorbic acid, involving ENZYMATIC REACTION of the glucose to produce an active reaction product, measures the difference in currents in two cells (or electrode systems) responsive respectively to the interfering substance alone and the interfering substance plus the reaction product. SELECTIVITY may be provided by the fact that e.g. glucose is electro-chemically inert before reacting with an enzyme or alternatively VOLTAGE SELECTIVITY between the interfering substance and the enzyme-reaction product may be used e.g. with PYROLYTIC GRAPHITE anodes ascorbic acid gives a current at 0À4 volts whereas hydrogen peroxide from the enzymatic reaction does not respond until about 1V. An alternative electrode is PYROLYTIC GRAPHITE, with the "a-plane" exposed and the edges sealed with epoxy resin, which behaves like palladium when used with palladium powder or a salt thereof in the electrolyte. HALF-CELL CONSTRUCTION for analysis of e.g. blood glucose comprises a carbon or metal electrode surrounded by a oxygen permeable tube 32 of e.g. silicone plastic (other materials listed). An enzyme layer is held between the flange at the foot of the tube and a permeable membrane 20 of Registered Trade Mark "Cellophane" (other materials listed). An anode 51 in a solution of sodium-phosphate or dilute sulphuric acid generates oxygen which permeates through the silicone-plastic to the enzyme. Hydrogen evolved at the cathode 52 is prevented from flowing back by a porous plug 58 - simple forms of cell construction having only some of these features are illustrated in Figs. 1.. 4 (not shown).
