Abstract: 305,329. Macintosh & Co., Ltd., C., Young, H. C., and Campbell, J. D. Dec. 13, 1927. Moulding indiarubber balls and hollow-ware.-In a machine for use in the manufacture of tennis balls, wherein hingedly-mounted cutting members in the form of " petals " close on one another to form and cut sheet rubber to create the " shell," the hinged " petals " when open lie flat and are operated by mechanical means energized by fluid pressure. In forming a shell, a sheet of rubber, which may be automaticallv transferred from a pile by means of a suction arm, is dropped on to four open petal-shaped cutting members 1 arranged in two diametrical pairs independently coupled by links 6 and slidable blocks 9 to a piston 11 or 11<a> so that the pairs of petals are automatically closed in succession upon the rubber to form a closed shell in readiness for subsequent moulding and vulcanization. The open petals lie substantially flat and the closing movement of the first pair of petals throws the rubber down into the cup formed by the second pair of petals thus avoiding the use of the operator's fingers and consequently ensuring a constant quantity of rubber being used and resulting in a uniform product. A pellet or drip of an inflating agent is dropped on the rubber sheet before closing. Near the end of the closing movement the links 6 abut against adjustable members 16 so as to intensify the closing pressure and ensure a good cut of the rubber by the petals. When the petals open the formed shell may be ejected by a mechanically-operated plunger embodied in the centre 2 to which the petals are hinged. Specification 13235/97, [Class 132, Toys &c.], is referred to.

Abstract: 1293376 Rounding off BELL PUNCH CO Ltd 3 July 1970 [3 July 1969] 33659/69 Heading G4A A digital electric calculator includes a means for rounding off numbers stored in a register by adding 5 into the decimal place below the last such place to be retained in the rounded off number, adding in any resulting carry, and clearing all the non-required stages to zero. Provision is made for shifting the answer, which may be displayed on a set of digit indicating tubes, one place to the right if any carry ripples through to the most significant digit of the number. The number of places to which rounding is to be made can be varied by connecting the corresponding number of gates to a counter so that depression of a rounding key feeds the corresponding number of pulses to a counter. Two further counters providing sequential outputs on a number of leads equal to the number of stages in the register holding the number to be rounded are provided, the number of pulses stored in the first counter causing the outputs of the further counters to be relatively displaced. The outputs of these two counters, together with shift pulses gated to the register each time the counter outputs change control the rounding. The register contents are circulated until the counter outputs indicate that the most significant digit to be cleared is in a register stage connected to an adder. A factor of five is then added to that stage and any carry resulting from the addition is propagated until the most significant digit of the number has been processed. When the register is circulated one more place the counter outputs initiate clearing of the portion of the number not required by causing a circuit to pulse all the non-required digits to zero. During the carry propagation an extra shift one place to the right is initiated if an additional place is created by carry ripple through.

Abstract: 1,005,948. Radiation dosimeters; measuring fluorescence. TOKYO SHIBAURA ELECTRIC CO. Ltd. Aug.27, 1963. No.33854/63. Heading G1A. A radiation dosimeter comprises a block of phosphate glass subjected to the dose to be measured and means for subsequently measuring the fluorescene of said block to ultraviolet light. The apparatus for measuring fluorescence comprises a source 1 of ultra violet light, a filter 4 to transmit 365 mÁ radiation and a lens and slit collimating system 2, 3 which irradiates the central portion 14 of the block 11. Orange fluorescent radiation passes through a collimating tube and a filter 5 passing wavelengths greater than 580 mÁ to a photo-multiplier 7 and amplifier 8. The effects of contamination are avoided as neither the block hotter 10 nor the surface of the block is irradiated save for the surfaces through which the ultraviolet radiation passes into and out of the block, and fluorescence on these surfaces cannot reach the photo-multiplier. The dosimeter may be slightly pressurized with clean air to prevent the ingress of contaminating dust when the block is replaced.
