Filed: 1945-12-11
Abstract: 604,970. Feeding animals. THORNTON, R. Dec. 11, 1945, No. 33427. Convention date, April 3. [Class 5(ii)] Relates to animal feeding devices in which predetermined quantities of food are released by the animal pushing against an oscillatory member, and consists in utilising the movement of the said member to grind the food during its passage from a hopper to a trough. A shaft 12 is mounted at the top of a box 10 with its axis parallel to the longitudinal centreline of the trough-shaped floor 11. A flap 16 is suspended on the shaft by bent strips 15 which carry counterweights 17 at their free ends and so balance the flap 16 that it closes the front opening of the box. A pawl 21 mounted on the upper surface of one strip 15 engages with a ratchet wheel 20 secured to the shaft, so that an animal pushing the flap 16 causes a partial rotation of the shaft 12. A hopper 23 communicating with a chute 22 is mounted in the upper part of the box near the ratchetwheel 20. Food is delivered to the hopper from an overhead bin. A grinding-disc 25 is adjustably secured to the shaft 12 before a second grinding-disc 24 fixed to the outside of the hopper over the chute mouth, the shaft passing through this second disc 24 and through the hopper. A worm 26 on the portion of the shaft within the hopper feeds grain through the annular space 27 between the second disc 24 and the shaft 12 to the space between the two discs where it is crushed and released through the chute to the floor of the box. The space between the discs can be regulated by a screw 28 situated outside the box at one end of the shaft 12.

Abstract: 1,154,465. Non-woven webs; lap forming apparauts. SNIA VISCOSA SOC. NAZIONALE INDUSTRIA APPLICAZIONI VISCOSA S.p.A. 26 July, 1966 [29 July, 1965], No. 33462/66. Headings D1N and D1R. A method of forming a non-woven fabric comprises mechanically crimping a plurality of coplanar parallel filaments, laying the crimped filaments on a receiving surface -and spreading the filaments to space them apart a distance less than the amplitude of the crimps and thus form a net-like structure of continuous crimped filaments each of which overlaps and is entangled with at least a part of adjacent crimped filaments where their crimps cross. The filaments may be superficially adhesive or may be treated to increase the adhesive characteristics of the filaments. The filaments may be gear crimped and then compressed or calendered to position the crimps in a single plane. The spreading of the filaments is preferably accompanied by a speed reduction to longitudinally shrink the filaments. The continuous filaments 10 are spun at 11, drawn at 13, possibly treated at 14, crimped at 15 and then spread by various means e.g. a convex roller, a collection of convex and cylindrical rollers or a divergent conveyor belt. The web so formed may be laminated with similar webs or with reinforcing sheets e.g. plastics sheets. The filaments may be of polymers such as polyamides, polyesters or polyolefines.

Cash registers; voucher issuing. - A cash register in which a voucher and duplicate are printed and severed from a web has a device for automatically conveying the duplicates to mechanism for stacking them in numerical order. In one form, the device may be made as a separate unit for attachment to standard cash registers. A vertical slide 1 is reciprocated on the guide plate 2 by links 3, 4, 6 the latter being driven from the main cam shaft 8 of the register. Grippers 14, 15 are attached to opposite ends of a horizontal shaft 13 carried by the slide 1, the gripper 14 being fixed whilst the gripper 15 is attached to an arm 24 pivoted on an extension 25 of the shaft 3. A catch 28 pivoted on the extension 25 carries a pin 31 engaging a slot 32 in the arm 24 and is so urged by the spring 33 that the grippers are maintained either open or closed. In operation the web B is fed between the printing cylinder 64 and a platen 35 pivotally supported on a cam-operated lever 05. When the slide 1 moves to the left the shaft 13 is rocked by links 17, 19 to bring the grippers 14, 15 towards the web. The platen 35 is actuated to print a duplicate voucher, which is gripped by the grippers 14, 15 through the action of the spring stud 34. A cam-operated guillotine 78 severs the duplicate and on the return movement of the slide 1 the grippers fall to the position shown in the Figure, the catch 28 striking a stop 36 causing the duplicate to be deposited between a pair of spring blades and a pusher piece 53. The latter is carried by a horizontal slide 40 which is connected to the slide 1 by links and moves to cause the duplicate to be pushed past the spring blades on to a stack in the tray 62. The slide 40 also carries a pivoted guide plate 54 which is pushed into a vertical position by a stop when the duplicate is being released by the grippers and thus ensures that the original ticket which is printed during the return movement of the slide is ejected from the machine into the tray 96. An eccentrically mounted roller 75 is adapted to print advertising matter on one side of the original but is rendered inoperative during issue of a duplicate. A further device 97 is adapted to print a distinctive mark only on the duplicate voucher. A printing roller 69 is adapted to print the date on the tickets.

Title: Selective cutting of a body by air abrasion
Inventor: DRAKE CYRIL FRANCIS
IPC: B26F3/00
Filed: 1965-08-06
Abstract: 1,088,896. Blasting. STANDARD TELEPHONES & CABLES Ltd. Aug. 5, 1966 [Aug. 6, 1965], No. 33808/65. Heading B3D. [Also in Division H1] A method for selectively cutting a body by air abrasion (i.e. abrasion by a stream of gas entrained particles) includes the steps of (a) Locally modifying the hardness of the material of part of said body at least in a surface zone by inducing a chemical change in that part of the body; and (b) Submitting the surface of said body to air abrasion whereby the harder portions of said surface are preferentially removed. The hardness of the material may be modified by exposure to radiation, e.g. visible, ultraviolet, electron or gamma radiation and/or heat. The body may be of natural rubber or other elastometer containing vulcanizing agents such as organic peroxides, e.g. benzoyl, lauroyl, octanoyl, acetyl and acetyl benzoyl peroxides which cause an increase in hardness on exposure to radiation and/or heat. In the manufacture of semi-conductor devices, a solution of natural or synthetic rubber in a petroleum mixture is compounded with 1% by weight of benzoyl peroxide and sprayed to a thickness of about 5 thou. on the surface of a silicon body. The coating is exposed through a masking negative to ultraviolet radiation for 15 mins. whereby the exposed portions of coating are vulcanized and become hard. The hard portions are removed, together with the desired thickness of underlying silicon by air abrasion using alumina powder. The unexposed, unvulcanized portions remain soft and resistant to air abrasion, and are removed by soaking in trichloroethylene. For cutting natural or synthetic rubber desired sections treated with a vulcanizing agent are hardened on exposure to radiation and cut by air abrasion. In the decoration of plastics and glassware a mask is applied as described above and desired sections of plastic or glass removed by air abrasion to form a pattern. Sections can be removed from layers of multilayer constructions and, where each layer is different in colour, a coloured pattern may be produced. In producing a charge pattern, a material normally of high surface resistivity is given an electrical charge over selected areas by irradiating with low energy electrons or illuminating with ultra-violet light. A vulcanizing agent in fine powder or liquid form is applied to the surface and is attracted only to the charged regions, so that on exposing the whole surface to active radiation the areas on which the vulcanizing agent has been deposited will become hardened and may be removed. The method may be used to provide masks for electroplating.

Abstract: 779,886. Radio navigation. MURPHY RADIO, Ltd. Nov. 24, 1955 [Nov. 24, 1954], No: 34110/54. Class 40(7) The invention relates to the Interrogator- Receiver in an Interrogator-Responder system wherein the receiver signals are gated by an auto-follow stroke with a memory arrangement, an automatic gain control circuit is provided, and there is a branched overlapping beam type homing circuit with a Miller integrator in each branch. Such a receiver may be obtained by combining the tracking of Specifications 693,930 and 779,887 but according to the present invention a simpler circuit arrangement is provided. In this a relay. preventing stroke drift when operated, is connected between the anode circuit of an amplifier in the automatic gain control circuit and the mid-point of a resistance connected between the anodes of the Miller integrator valves, said mid-point being joined to the grids of the integrators through capacitors giving a long time constant effect. As shown the stroke and signal are applied to gate valve 12 whose output is applied to diode rectifiers 15 and 16. In accordance with previously mentioned Specification 779.887 the output of rectifier 15 is fed over a switch operated synchronously with the aerial switch to the grids of two Miller integrators 17 and 18 having grid circuit time constants long compared with the switching period. The' homing indicator 28 is connected between the cathodes of the integrator valves and switching for co-operation with either "Babs" or "Eureka" responders provided. Diode 16 is used to provide the A.G.C. signal which is reversed in phase by amplifier 29 and fed out from a tapping on resistor 32. According to the present. invention the polarized relay coil 59, which operates contacts preventing normal stroke search drift and thus provides memory during absence of signals is coupled between the anode of A.G.C. valve 29 and the mid-point of resistor 51 connected between the anodes of the Miller integrator valves 17 and 18. A limiting resistor 61 is provided and the tapping is connected to the H.T. line through resistor 52 and to the grids of each of the valves through relatively large capacitors 53 and 54. The extent of the memory period depends on the values nf resistor 51 and capacitors 53 and 54. It is also dependent on how long signals have been received as the mid-point of resistor 51 onlv slowly takes up the potential it has when signals are present. The anode of valve 29 varies in potential with relatively little delay in accordance with the strength of the signals received. Specification 690.480 also is referred to in the Provisional Specification.
