Title: Improvements in or relating to machines for wrapping confections or sweetmeats and similar articles
IPC: B65B35/26
Filed: 1933-02-22
Abstract: 400,480. Wrapping-machines. HESSER MASCHINENFABRIK-AKT.-GES., F., 99, Olgastrasse, Cannstatt, Stuttgart, Germany. Feb. 22, 1933, No. 5375. Convention date, Feb. 22, 1932. [Class 94 (i).] Machines for wrapping sweetmeats &c in paraffin and like paper are arranged so that the parts of the feeding mechanism can be readily removed for cleaning and replaced. The mechanism comprises a disc-shaped intermittently rotatable table 3 carrying the holders 101 for the articles to be wrapped. Openings 5, 6 are formed in the discs for the reception of pins 7 flanged at 8. The guides 9 in which the holders are mounted are formed with supporting plates 11 apertured at 12, 13 to fit on the pins 7. Clamping cheeks 15, 16 are formed with bearing eyes 19, 20 for engagement by the tops of the pins. The levers 17, 18 carrying the clamping cheeks are geared at 21 for simultaneous movement. The whole assembly is secured in position by a disc 25 bearing on the tops of the pins and secured to the top of the shaft by a nut 28. It is only necessary to remove this nut to free all the parts for cleaning. The Specification as open to inspection under Sect. 91 comprises also a description of the mounting of the folding mechanism of a wraping-machine. The folding mechanisms, of which one is shown in Fig. 6 (Cancelled), are mounted on rods 33 passing through bores in a guideplate 32 and in the machine plate 1. The rod is normally held down by a spring so that the lower end rides on a cam-operated actuating lever. For removal, the springs are unhooked and the rod and associated mechanisms can be removed for cleaning. Other rods carrying pressing, heat-sealing, and cooling devices may be similarly arranged. Guide rails 55, 56, which serve as abutments for the folders 47, 471, and for the pressing elements are also mounted with upper rails and guide-plates for collective removal for cleaning &c. This subject-matter does not appear in the Specification as accepted.

Title: Nuclear reactor control
Inventor: UNTERMYER SAMUEL
IPC: G21C7/18
Filed: 1957-02-18
Abstract: 828,352. Controlling nuclear reactors. UNITED STATES ATOMIC ENERGY COMMISSION. Feb. 18, 1957, No. 5389/57. Class 39(4). Control members are arranged in a group unit so that some members move longitudinally with respect to the remaining member or members. In this way maximum reactivity is obtained by aligning neutron absorbing portions on the different members and minimum reactivity is obtained by spacing these neutron absorbing portions. Fig. 1 shows member 104 stationary with moving members 103, 105 in maximum neutron absorbing position. By rotating a rod 208 having oppositely threaded portions the two members 103 and 105 are moved in opposite directions so that the neutron absorbing portions 106, 108, 110 are in line As shown in Fig. 3 each of the members 103, 105 is moved by a connecting pin 207 and the three control members are contained in a matrix 205. In a second embodiment, Fig. 5, five control members are assembled in the group unit, two of these members moving fast in opposite directions and two members moving slowly in opposite directions. In this case two threaded rods 502 are employed with gear wheels connecting, Fig. 4 (not shown). In a further modification, Figs. 7, 8, three control elements 708, 710 are moved outwards from a stationary central member 709 by the linkage shown, when the central member 709 is lowered. The position for maximum reactivity is shown at (b) and the provision for minimum reactivity at (a). In this case the control members are operated by a rod 713 projecting through the shield 701. All modifications have the advantage that the control members remain wholly within the active portion of the reactor. In a reactor with a lattice of fissile material 1, Fig. 10, the maximum reactivity position for control members is shown at 3 and the minimum position at 2. The neutron absorbing material contains boron, lithium and thorium.

Filed: 1942-04-23
Abstract: 557,012. Linear-dimension gauges. KAPELLA, Ltd., WARMISHAM, A., and CLIFFORD, T. W. April 23, 1942, No. 5469. Addition to 544,938. [Class 106 (ii)] [Also in Group XX] In scale-reading apparatus according to the parent Specification magnified and superimposed images of the markings are produced by a lens and viewed through a telecentric stop. The invention, or that according to the parent Specification, may be applied to sliding caliper gauges. As shown in horizontal section in Fig. 1, and in elevation in Fig. 2, the reading apparatus is attached to an object C movable relatively to a vertical scale B, and comprises a casing A attached by feet A<SP>1</SP> to the object C. The casing contains a graticule D slidable by a screw head D<SP>1</SP>, a lens E producing magnified superimposed images of the scale B and graticule markings, and a telecentric stop F, usually smaller than the pupil of the observer's eye, through which the images are viewed; windows A<SP>4</SP> may admit light to the scale, &c. The scale B has a vertical line B<SP>1</SP> thereon, and the graticule is marked with a horidontal scale D3, Fig. 3, and a horizontal line D2. the graticule is slidable at an inclination to the horizontal such that the scale D3 rises through the height of one division of the scale B while its whole length passes across the line B<SP>1</SP>. The zero of the scale D<SP>3</SP> is in coincidence with the line B<SP>1</SP> when the line D<SP>2</SP> is in correct reading position for the scale B, and, in use, the scale D<SP>3</SP> is moved from this position, until the line D<SP>2</SP> coincides with a graduation on the scale B, the scale D<SP>3</SP> being then read against the line B<SP>1</SP> to provide a reading of the fraction of a division of the scale B. The division on the scale B may each be inch, and the scale D3 may contain 25 divisions, each equivalent to one hundredth of an inch on the scade B. The scale D<SP>3</SP> may be fixed relatively to the scale B, the line Bl being then carried by the graticule. Modifications are described in which the sliding graticule is located away from the scale B and the images are superimposed by means of reflectors ; the line B<SP>1</SP> may then be on the scale B or on a fixed graticule. Figs. 8 and 9 show a sliding caliper gauge wherein the graticule markings are carried by a prism N slidable lengthwise over the scale B, within a slider L, viewing being effected through a stop F by a lens E and reflector O. The slider L may be made mainly of transparent synthetic resin, may be coarsely adjusted by means of a bracket F, screw P<SP>2</SP>, unit P<SP>1</SP> &c., and may be clamped by a screw L3. A sliding caliper gauge is described in which the scale and graticule have adjacent surfaces, and also a construction of reading apparatus forming a separate unit attachable to a scale as and when required.

Title: Improvements relating to data storage cells
IPC: G11C11/414
Filed: 1969-01-30
Abstract: 1,207,084. Bi-stable circuits. INTERNATIONAL BUSINESS MACHINES CORP. 30 Jan., 1969 [6 March, 1968], No. 5522/69. Heading H3T. Each time a bi-stable T1-T2 is switched on by a pulsed power supply V c  it reassumes that state it had before switching off, by virtue of internally stored charge whose rate of discharge is made low in relation to the pulsing frequency by arranging semi-conductor switching means such as diodes D1, D2 to confine the discharge to a relatively high impedance path. For example, if T 1 is on, and T2 off when the supply V c  goes off, the diodes D1, D2 become non- conductive, transistor T2 can be disregarded since it was off, and transistor T1 can be regarded as a series combination of base-collector diode and capacitance (12, 13, Fig. 2, not shown) and emitter-base diode and capacitance (14, 15). The relatively high voltage which was at T2 collector 4 before switch-off can only discharge through the e-b diode (14) from the capacitance (15). The impedance of the diode (14) rises non-linearly and by a substantial amount when the voltage (at 4) has fallen to about 0À8 volts, and this order of voltage is therefore available when the power switches on again to ensure correct resetting of the bi-stable. The collector voltages in the embodiment swing between 0À05V and 0À75 volts approximately. An emitter coupled pair of transistors (T3, T4, Fig. 3, not shown) having a current source transistor (T5) perform read and write functions, the control pulse applied (at 20) to the current source transistor being preferably coincident with a power supply turn-on pulse. An OR-gate (Fig. 4, not shown) ensures that the power turn-on pulses V c  are produced when either normal timing pulses are received (at 44) during normal regeneration, or a control pulse is received (at 46) from a logic decode matrix. T1 and T2 may be multiemitter transistors.
