Abstract: 498,021. Electricity supply. EDWARDS, F. S., SCOLES, G. J., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd.. July 2, 1937, No. 18477. [Class 38 (iv)] Condenser arrangements -In an impulse generator in which condensers 1 in groups or stages A, B, C D are charged in parallel through charging resis tances 2, 4 and dischargec in series through spark gaps 3, control of the wave tail and wave front is obtained by connecting the spark gaps to the resistances, such as 2, at intermediate points whereby a local discharge circuit for each condenser 1 includes a part 2a of the resistance which is not included in the load discharge circuit of the condenser, which latter circuit includes the other part 2b of the resistance. The part 2a effects wave tail control and the part 2b wave front control. Additional resistance 9c in series may be provided for wave front control and resistances 12 for wave tail control. In an alternative arrangement, the spark-gaps may be connected to intermediate points on the charging resistances 4, the lowermost gap 3 being connected through a separate auxiliary resistance. Further resistances 12 may be connected in shunt with the resistances 4. The resistances 2b in series with the gaps may be mounted on an insulated support or shank of the gap. The wave tail resistances 2a may be composed of two or more sections which may be short-circuited by links or bars. Disconnection of the resistances 2a produces a long wave-tail determined by the resistances 12. Specification 344,862 is referred to.

Filed: 1953-07-08
Abstract: 731,496. Guided hoists for stacking; step-bystep conveyers. TOLLEY, B. G. July 8, 1953, No. 18917/53. Classes 78 (1) and 78 (3). An apparatus for stacking crates or the like comprises a frame 7 slidable on fixed guides 6, means actuated by an arriving crate to cause the frame 7 to descend, engage and elevate the crate to allow the next crate to be received beneath it, and lifting fingers 15 which are pivoted to the frame 7 and are adapted to be moved into crate engaging positions on each descent of the frame. When a crate arrives beneath the apparatus it operates a control lever 20 which, through a single revolution clutch mechanism 13 initiates rotation of a wheel 11 through one revolution so causing a crank 9 to lower and raise the frame 7 through a distance corresponding to the depth of a crate. With the frame 7 in its raised position and supporting one crate 22, on arrival of a further crate 23 the frame is lowered and during the part of its down stroke when the crate 22 is supported by the crate 23 fingers 15 pivot inwardly to disengage the crates but when a rod 18 contacts an abutment 19 the fingers 15 are all moved outwardly so engaging both crates 22, 23, which are raised through the depth of a crate during the following up stroke. Successive crates cause a repetition of this cycle until the stack reaches a height at which the top crate engages an arm 24 which moves the abutment 19 out of alignment with rod 18 so preventing further operation of the fingers until the stack has been removed.

Title: An improved folding writing tablet or the like
IPC: B42D3/00
Filed: 1933-07-04
Abstract: 420,991. Writing or games board ; hinges. SCOTT, C. D., 62, Clifton Hill, St. John's Wood, London. July 4, 1933, No. 18919. [Classes 16 and 132 (ii)] [See also Group XXV] A foldable tablet or board for use as a writing support, game board, &c. comprises hingedly connected sections, and means connected with the hinges for locking the sections in butted and aligned position. In the arrangement shown in Fig. 1, the two sections a, b of the board are connected by cranked hinges h so that when the sections are folded they will be maintained in spaced relationship to each other, and writing paper, game pieces, &c., can be accommodated therebetween. Each cranked hinge h has hinged at right angles thereto, and on the outside edge thereof, a further cranked hinge i which can be brought into alignment with the main hinge to allow the board to be opened or closed, but which can be swung downwardly through two right angles when the board is opened out to lock the board in that position. Instead of a second cranked hinge a pair of flaps may be hinged to the sections of the board at right angles to the main cranked hinge, the flaps being connected at their free edges by a rule hinge the centre of which can be brought into coaxial relation with the hinge pin of the main hinge to allow the board to be folded. A spring on the hinge of one flap turns the flaps into looking position as soon as the board is extended. In the construction shown in Fig. 3, the board folds about a double rule hinge o the parts of which are connected by a hinge p arranged at right angles to the rule hinge. When the two parts of the hinge are folded together the board can be folded, but when the board is unfolded a spring q opens the two parts to lock the sections of the board in extended position. The top hinge leaves are extended over and secured to the flat face of the board ; in a modification the top leaves are secured by screws to the edge of the board. In a further arrangement two flat plate hinges are secured by their bottom leaves to the edges of the sections of the board, and are connected together at the top edges by a rule hinge. When the top leaves of the hinges are in alignment with the bottom leaves then the board can be folded, but when the board is unfolded a spring on the pin of one hinge forces the top leaves of the hinges flat against the top of the board, in which case the latter cannot be unfolded. If, in the latter arrangement, the top leaves of the hinges are folded flat to the edge of the board, the latter can be folded in the opposite direction, but there will be no space between the sections of the board thus folded.
