Title: Improvements in and relating to multi-platen presses
IPC: B30B7/02
Filed: 1960-02-02
Abstract: 876,010. Laminating-apparatus. SIEMPELKAMP, E. Feb. 2, 1960 [Feb. 5, 1959], No. 3635/60. Class 140. In multi-platen presses, for chip boards, fibre boards, plywood, &c., in which the platens are so connected to the press table 2 as to close simultaneously during the press stroke and to open on release, strain on the connecting device, due to differences in thickness of the press material or to the non-charging of some of the platens with such material, is avoided by releasing the device on closure of the platens and during the press period. As shown the platens 4 are connected at each of their four corners by cords 6 to stepped pulleys 5, the pulleys themselves being connected by cords 7 passing under pulleys 8 to the press table 2. The pulleys 8 are connected to fluid pressure cylinders 14 having control mechanism 15 operating to hold the pulleys during the rise of the table until the platens are closed on the press material, to allow the pulleys to rise during the pressure period and finally to lower them on descent of the table to open the platens. Ratchet and pawl mechanisms 11 having control means 12 prevent reverse rotation of the pulleys 5 as the pulleys 8 are raised. In a modification the cords 7 pass under fixed pulleys 8 and are connected to a cross beam lying beneath the pressure table and raised with the table by fluid pressure to the point at which the platens are closed, the table then being raised further for the pressure stroke. After the pressure stroke the cross beam may be raised beneath the table to support it during the release period.

Patent GB-1064361-A (GB)
Title: A method of sterilizing
IPC: A23L3/10
Filed: 1965-01-27
Abstract: Materials contaminated with microbial spores are sterilized by reducing the pH of the material, preferably to about 1.5, and maintaining the material at this reduced pH until the spores have been converted to a substantially more heat sensitive form, raising the pH of the material to a desired value, preferably the original value, and heating the material to kill the spores before they have had opportunity to be reconverted to their original form.  The material may be sealed into a container prior to heating.  The process may be applied to foodstuffs of all types, cosmetic, medicinal, and dental preparations, vitamin preparations, and any other organic material subject to microbial spoilage.  The process may also be used for sterilizing medical, industrial, and scientific materials and apparatus.  The reduction of pH may be effected by an acid such as nitric, hydrochloric, sulphuric, phosphoric, hydrobromic, acetic, chlor- and trichlor-acetic, fumaric, maleic, salicyslic, and tartaric acids, or by an acid salt such as sodium bisulphate.  The raising of pH may be effected by basic materials such as sodium, calcium, or potassium hydroxide, sodium or potassium carbonate or bicarbonate, or disodium phosphate.  In the case of impervious materials water washing will suffice.  For foods hydrochloric acid and sodium carbonate or hydroxide are preferred.ALSO:Materials contaminated with microbial spores are sterilized by reducing the pH of the material, preferably to about 1.5, and maintaining the material at this reduced pH until the spores have been converted to a substantially more heat sensitive form, raising the pH of the material to a desired value, preferably the original value, and heating the material to kill the spores before they have had opportunity to be reconverted to their original form.

Title: Improvements in or connected with Weft Fork Motions of Looms for Weaving.
Inventor: WRIGHT WILLIAM
IPC: D03D51/34
Filed: 1916-03-14
Abstract: 102,302. Wright, W., and Barker, C. March 14, 1916. Stop-motions, weft. -The radius-rod for operating the camslide or cam-lever 3, .Fig. 2, is made in two parts 1, 2 so as to be extensible. The part 1 is pivoted to a bracket 4 on the breast beam and has a slotted sleeve 6 adapted to receive the part 2 of the radius-rod, which is secured to a sliding collar 9 by a pin 8 passing through the slots in the sleeve 6. A spring 11 between the collar 9 and a collar 10 on the sleeve 6 normally keeps the radius-rod contracted. On the rearward movement of the lay, the cam-lever 3 is moved to raise the weft fork to its highest position, whereupon the lever 3 is stopped by a stop 3<a> on the weft-fork bracket or by a stop on the lay, further motion of the lay extending the radius-rod against the action of the spring 11. To keep the weft-fork motion inoperative until the first beat-up of the lay after re-starting the loom, the bunter lever 13, Fig. 3, is provided with a pivoted part 15 normally held in the position shown by means of a spring 16 carrying a projection 16' engaging a recess in the part 15. On failure of weft, the cam-lever 3 is locked by the weft fork, so that its stud 3<2>, at the forward movement of the lay, engages the pivoted part 15 and turns the bunter lever to stop the loom. At the same time, the part 15 is turned upwards into its inoperative position by the engagement of its finger 15<1> with a fixed part 12<2>, and is locked in this position by the projection 16<1> riding over the top of it. At the first beat-up after re-starting the loom, a bunter 17 on the weft-fork supporting bracket engages the upper part of the spring 16 and allows the pivoted part 15 to fall again into operative position to indicate on any subsequent beat-up.

Abstract: 1,140,121. Magnetic storage apparatus. UNITED STATES OF AMERICA, SECRETARY OF THE ARMY. 27 Jan., 1966 [27 Jan., 1965], No. 3784/66. Heading H3B. Information is stored in an elongated strip of anisotropic thin magnetic film 15, Fig. 2, by applying current pulses to a strip of thin conductive film 16 mounted lengthwise of the magnetic film strip, and at the same time passing a sonic wave through a substrate 12 supporting the magnetic film strip. A second strip of thin magnetic film 17 of inverted channel cross-section is applied over the conductive film so that the two magnetic films 16, 17 together form a tube, Fig. 3 (not shown), enclosing the conductive film, the easy axis of magnetisation being circumferential of the tube. Current conductors are joined to the ends of the conductive film 16, the connection at one end incorporating a rectifier 18. The substrate has a transducer 13, e.g. a piezoelectric crystal, applied to one end and a sonic-wave absorbing medium 14, such as rubber, mounted at the opposite end. Several magnetic film strips together forming a storage array may be mounted on a common substrate, Fig. 1, with each strip connected by a respective conductor 21-26 to read and write circuits 20, 19. A plurality of such arrays may be connected in parallel as shown. To write into a magnetic film strip in a given array, information pulses are applied from the write circuit to the appropriate conductive film, and at the same time a pulse is applied from a source 27 to the transducer of the common substrate. For reading from a given array the transducer of the substrate concerned is pulsed and voltages induced in the conductive films are detected by the read circuit.

Title: Testing seminconductor devices
IPC: G01R31/28
Filed: 1975-01-29
Abstract: 1451295 Testing integrated circuits INTERNATIONAL BUSINESS MACHINES CORP 29 Jan 1975 [20 Feb 1974] 3839/75 Heading G1U [ Also in Division H1] An LSI comprising a plurality of input contacts and output contacts with logic circuitry connected between them includes means for determining, prior to testing the circuitry, whether there is good contact between the contacts and test probes. The means comprises a logic AND circuit having a plurality of inputs each connected to a respective one of the input contacts for producing, in response to input signals applied to all the input contacts, an output signal and means for coupling this signal to all the output contacts to bring them to a selected signal level. As described, Fig. 2, the AND circuit comprises a set of Schottky diodes 21-1 to 21-N formed on a common P region located near the dicing kerf and a further set of diodes 23-1 to 23-N formed on the same region or, if the number of contacts is very large, on a region connected to it via a buffer amplifier connects its output to output contacts PO1, 2 &c. either directly, as shown, or via the base electrodes of emitter followers 17 &c. To test, positive going signals are applied to the input terminals from a test apparatus via a probe assembly. If contact to all input contacts is good a positive AND circuit output results which is passed to all properly contacted output contacts, over-riding any negative signals derived by the logic circuitry. If in normal use the chip can have concurrent positive signals applied to all its input terminals, an additional, normally reverse biased diode 21-X connected to additional terminal P1X is required to prevent the diode array over-riding the logic circuitry in normal operation to give a false output, and if the circuitry can produce positive signals at all its output terminals additional diode 23-X is needed to enable a negative AND circuit output indicative of a lack of input contact integrity, which is over-ridden at terminals PO1 &c. to be sensed at an additional output terminal POX. The test apparatus responds to positive signals at all output terminals to terminate lowering of the probe assembly and trigger the circuitry testing cycle.

IPC: B64C11/00
Filed: 1917-03-20
Abstract: 115,060. Prost, C. March 20, 1917. Aerial machines without acrostats: planes, arrangement of; proppelling. - Relates to flying- machines of the kind in which the supporting. planes are reciprocated along inclined guideways by means of endless chains so as to act, in the forward stroke, merely as supporting-planes, and in the rearward stroke as propelling - surfaces. The planes 16 are connected to endless chains 6, passing over wheels 5, 5<1>, by cross-rods 20, Figs. 4 and 5, engaging between a fixed arm 17 and spring-hinged arm 18 on the plane. During the forward stroke along the upper side of the chain, the planes are held parallel to the chain by the engagement of the rods 20 and pins 21 in guide-slots 9. At the end of the forward stroke, each plane is released from the rod 20 by the engagement of the arm 18 with an abutment 46, Fig. 10, after which the rod 20, carried on by the chain, engages a lever 29, 30, Fig. 8, thereby raising a lever 32, the heel 33 of which forces the pins 21 down into guide-slots 10. The plane falls about the pins 21 into the position shown in broken lines, and is again taken up by the rod 20, which engages the lower guide-slot 12 during the rearward stroke. At the end of this stroke, the pins 21 slide up slots 10<1>, Fig. 11, and enter the hooked end 42<1> of a lever 42. As the rod 20 rises farther, the plane is rocked about an abutment 50, whereby the rear end of the plane and the lever 42 are lowered, this movement of the lever 42 operating a right-angled lever 36 to withdraw bolts 38, 39, so as to allow the rod 20 to pass and, by raising a catch 45, to enter again the guide-slot 9. The pins 21 also enter the slot 9 and pass a catch 48, the forward stroke then proceeding as before. If the motor stops. the planes on the lower chain-path may be lowered into position to act as supporting-planes by the following device. A guideway 49, Fig. 13. mounted on arms 53, carries pulleys 51, 51<1> over which passes an endless chain 52. Normally, the guideway and the lower planes 16 are in the position shown in broken lines. When the motor stops, the pilot raises the guideway to the position shown in full-lines by means of a lever 58, 54, whereupon the chain 52 engages and raises the lower end of a lever 25, which, being pivoted to the plane at 26, Figs. 4, and 5, withdraws the pins 21 from the guide-slots 10 by means of cords 23. The planes 16 then fall to the position shown in full lines in Fig. 13, restoring the lever 25 to its normal position and thereby engaging the pins 21 in the slot 12. Two sets of planes may be provided, one at each side of the machine. Planes, construction of. - Each plane is composed of a flat frame 15, Figs. 4 and 5, surmounted by a convex frame 16, on which the fabric is stretched.
