To transfer articles 212 from storage, a retrieval vehicle 200R, Fig. 5, is preferably positioned adjacent the storage bin 21 containing the pallet bearing the required articles 212, and the pallet is withdrawn into the aisle 12 by laterally extendible means 232-236 on the vehicle 200R. The picking head 275, preferably operated by suction, is positioned above the articles, with the vehicle 200V running on the guides 18 above those of the vehicle 200R. The head 275 is then lowered to pick up the articles 212 from the top tier, and the vehicle 200V is moved on the rails 18 to enable the articles 212 to be deposited on the receiving vehicle 200M where a stack of required articles is built upon a pallet. For transfer of vehicles 200 between aisles and levels, a vertical lift 100 movable on rails 14, 16 is provided, the lift 100 having rails 154 for receiving the vehicles 200 from the guides 18. The system is provided with an input station 320, at which palletized loads 210 may be received from a conveyer 322 by the vehicles 200 and an output station 340 at which goods may be discharged on a conveyer 345, a retractable bridge 400 across the path of the lift 100 allowing vehicles 200 to pass between the stations 320, 340. In an alternative construction, Fig. 7 (not shown), the picking head 275 may be mounted for horizontal movement relative to the picking vehicle (200 V') into and out of the storage bins 21, so that articles 212 may be picked up and transferred directly to the receiving vehicle 200M without the use of a retrieval vehicle 200R.

Abstract: 699,137. Winding yarn. MASCHINENFABRIK SCHWEITER AKT.-GES. March 20, 1952 [April 24, 1951], No. 7184/52. Class 120(ii) A quick-traverse winding frame of the kind in which the bobbin 3 is driven by a drive drum 16 and, in order to prevent the formation of ridges, performs a rocking movement in the plane of the axes of the bobbin and drum about a transverse axis, is characterized in that the transverse axis x1 about which rocking of the bobbin takes place intersects the line of contact between bobbin and drum, or passes in very near proximity thereto, the axis remaining in that position as the bobbin grows in size. The bobbin is carried by a spindle 20, 22 mounted in a fork 23, the side-members of which are pivoted at 24a to a bar 25 pivctally carried at 19 and rocked by a linkage 26, 28.

Title: Improvements in electronic trigger circuits
IPC: H03K3/2893
Filed: 1965-02-19
Abstract: 1,077,878. Detecting threshold level. SOCIETE DE CONSTRUCTIONS ELECTROMECANIQUES JEUMONT - SCHNEIDER. Feb. 19, 1965 [Feb. 25, 1964], No. 7307/65. Heading H3T. To determine if a variable D.C. voltage is above or below a given threshold value it is applied to a bi-stable circuit in conjunction with a pulsating voltage which goes outside the two levels at which the bi-stable circuit changes over; the output of the bi-stable circuit is passed to a further bi-stable circuit via a delay circuit of time-constant longer than one cycle of the pulsating voltage, so that the second bi-stable circuit changes over at a definite value of the variable voltage. If this definite value is to be the upper threshold of the first bi-stable circuit, the variable and pulsating voltages are applied via an AND circuit which passes on whichever instantaneous value is the lower. For use with the lower threshold an OR gate is used to pass on whichever instantaneous value is the higher. The time constant of the coupling circuit should be asymmetric, having a greater value for falling or rising voltages respectively, in these two modifications. Such asymmetry can be provided in the former case by the conduction or non-conduction of the output transistor of the first bi-stable circuit, and in the latter case by a parallel diode/resistor circuit in series with the lead from the first bi-stable circuit to the shunt capacitor that provides the delay. More than one input voltage can be present simultaneously. The bistable circuits are preferably transistor Schmitt trigger circuits. If necessary, the D.C. level of the input signal is shifted to bring it in the proper relationship to the threshold levels of the first bi-stable circuit.

Abstract: 512,638. Valves. MOSS, F. March 10, 1938, Nos. 7434 and 34156. [Class 135] A device to facilitate washer replacement on water taps comprises a hollow body portion 1 enlarged at one end to accommodate the inlet connection of the main valve 7 and with a reduced threaded portion at the other end to receive the inlet pipe 6. A conical valve 3 adapted to co-operate with a packing ring 4 in the end of the fitting is formed on a spindle 2 freely mounted in the body. The spindle carries a cross-bar 5 adapted to be engaged by the tailpiece of the main valve to hold the head 3 away from its seat. In a modified arrangement for use with pillar taps, a connector having a long internal thread and provided with a lock-nut is interposed between the tail of the valve and the supplementary fitting. In another form the enlarged end is internally or externally threaded with a left-hand thread engaged by a nut also screwed on to the outlet fitting. In this form the cross-bar is replaced by an apertured disc faced with packing washers. In a modification the conical valve co-operates with a seat on an internal partition.

In a joint, such as a Hooke's joint, having a trunnion 16 journalled in ball or roller bearings 22 in a bearing cup 17 adapted to be supplied with lubricant, the lubricant is retained and grit &c. excluded by a sealing-ring 26, Fig. 2, sealingly secured to the cup and having at least two spaced resilient lips 33, 34 engaging the trunnion. The ring 26 may be of natural rubber or synthetic rubber, such as Neoprene or the material sold under the Registered Trade Mark " Buna N," or nylon and is press-fitted into or cemented to a metal cup 27 or held therein by tangs on the interior of the cup penetrating the ring. The cup 27 is inserted in a bore 24 in the bearing cup 17 and acts as an end stop for the roller bearings 22. In a modification, Fig. 4, the cup 27 is replaced by a metal backing ring 32 and the ring 26 is compressed in the bore 24 with a shoulder 42 abutting the end wall 29 of the cup 17 and has an integral skirt 43 sealingly engaging the trunnion at points 44 and 45. In another modification, Fig. 5 (not shown), the lip 34 is omitted and the ring 26 is formed with a skirt engaging the frusto-conical portion of the trunnion. When the bearing is charged with fresh lubricant through a passage 19 in the trunnion the lips 33, 34 and skirt 43 are deformed to allow the used lubricant to escape.

Abstract: 1537015 Fusible cut-outs McGRAW-EDISON CO 23 Feb 1977 07686/77 Heading H2G An electric fuse has two electrical paths of different current ratings each including a fusible element but of identical current-interrupting characteristics, the first path including a disconnecting means responsive to a long-term relatively low-overcurrent to disconnect the fusible element and thereby cause the second electrical path to respond to the low-overcurrent and open the circuit. In the embodiment the first path includes four parallel fusible elements 50, 52 (54, Figs. 4 & 7, not shown) and 560, and the disconnecting means comprises four masses of heat softenable material 135, see Fig. 8 (also 137, 139, 141, Fig. 7, not shown) which together with other members connects the fusible elements to heat absorbers 28, 34. The second path comprises a fusible element 46 electrically connected between the heat absorbers 28, 34 and the metal cap 80. If a relatively low-overcurrent flows through elements 50, 52, 54 and 560, the heat generated will soften the masses 135, 137, 139 and 141 and the springs 140, 142, 144 will pull the members 134, 136, 138 away from the ends of the four fusible elements thereby confining the overcurrent to element 46 which fuses. Arc quenching material 93, 166, 176 is provided within the two housings 92, 98 and the end caps 56, 80 contact the housing 98 for good heat transfer.
