Title: Improvements relating to the cutting of sheet blanks
Inventor: BRICHARD EDGARD
IPC: G06F19/00

Abstract: 1,212,026. Cutting sheets and webs. GLAVERBEL. 12. Dec., 1967 [13 Dec., 1966], No. 56469/67. Heading G4A. [Also in Division C1] Materials in sheet or web form are cut into pieces of dimensions predetermined by an order book by cutting the sheet or web into sections along spaced lines and cutting the sections into required pieces a check being made before at least one section is cut that a suitable cutting plan for the following section can be devised having regard to any defects the sheet or web may contain, the cutting plan being so as to limit waste of material according to a predetermined criterion. The process is preferably performed under the control of a computer program and is of particular application to cutting sheets of glass according to three different specifications (e.g. for horticultured purposes, window panes and glass for mirrors respectively) from long webs of glass following its manufacture. Sheet metal, plastics wood and paper making applications are also referred to. The required pieces are preferably arranged, by the computer, into groups such that the aggregate width of the pieces in each group is less than or equal to the sheet or web width. The pieces within any one group are preferably of similar lengths. Individual pieces may feature in more than one group and in different orientations if the material is isotropic. Limitations may be imposed as to the number of pieces that may be cut from any one section or the number of cuts that may be made per The pieces to be cut may be arranged in an order of priority based on size (e.g. largest pieces first) and or on cost-to-area ratio where the cost (or marginal cost price) of each required piece is based upon experimental data about the unit cost of different sizes of sheet taking into account the different amounts of wastage for different size sheets in varying circumstances. Small pieces may be inclined with respect to the sides of the blank to avoid defects and so-called warehouse sheets may be cut if no suitable cutting plan appears to be possible. The blank may be marked manually with colours (a 3- colour classification is described) to denote the type and location of any defects. The marks may then be detected photo-electrically to feed this information automatically into the computer. Alternatively, the information may be fed in manually. The computer may produce a number of alternative plans for cutting and select the most economic. The cutting tool may be directly controlled by the computer or may be controlled off-line (using punched cards, punched tape or magnetic tape). Alternatively, printed instructions for manual cutting may be produced. The program may be prepared in punched cards, punched paper tape or magnetic tape. A number of programs in the form of flow-charts are disclosed.

Abstract: 1,195,520. Aryl phosphorhydrazidothionates. OLIN MATHIESON CHEMICAL CORP. 6 Dec., 1968, No. 58074/68. Heading C2C. [Also in Divisions C3 and C5] Aryl phosphorhydrazidothionates having the formula (RO) n P(: S)(NHNH 2 ) 3-n  in which n is 1 or 2 and R is aryl of 6 to 18 carbon atoms and is unsubstituted or is alkyl-, alkoxy- or halosubstituted, are obtained by reacting an appropriate aryl phosphorochloridothionate with aqueous or anhydrous hydrazine, suitably in the presence of an inert solvent, e.g. a hydrocarbon, a halogenated C 1-4  alkane, an ether or an alcohol, methylene chloride being a particularly useful solvent. Examples are given for the production of a mixture of bis-(nonylphenyl) and monononylphenyl phosphorohydrazido and dihydrazothionates, and of compounds in which n is 2 and R is p-tert.-butyl, o-tolyl, 2,4,6-trimethylphenyl, p-methoxyphenyl, p-tolyl, mtolyl and p-octylphenyl, respectively. The invention also includes as novel products those in which R in the formula is an alkylaryl radical of 9 to 18 carbon atoms. The products are useful as stabilizers for olefins, rubbers, and brake fluids, as scorch inhibitors in polyurethane foams, as antioxidants in fatty oils, as additives in lubricating oils and greases and paints, as plasticizers for vinyl polymers and as corrosion inhibitors, e.g. in boiler feed water. Bis - (p - methoxyphenyl) phosphorochloridothionate is obtained by adding PSCl 3  (0.25 mole) rapidly to p-methoxyphenol (0.5 mole) and dry pyridine (0.5 mole) in toluene and heating the mixture at 100‹ C. p-Methoxy phenyl phosphorodichloridothionate is also recovered from the reaction mixture.

The foam may be a polyurethane, preferably rigid or semi-rigid, obtained by reacting a polyol and a polyisocyanate, an epoxy resin obtained by reacting a polyepoxide with a curing agent, polyesters, polyvinyl esters or phenolics. Other additives, e.g. foaming agents, e.g. trichloromonofluoromethane are included.

Abstract: 1,248,787. Anti-skid control systems. MULLARD Ltd. 13 Dec., 1968, No. 59524/68. Heading F2F. In an anti-skid brake system fluid is bled is bled into a reservoir on wheel-lock and pumped back into the system when the wheel accelerates again. A number of criteria are recited for relieving and restoring brake pressure in accordance with various states of deceleration and speed of the wheel, singly or in combination according to the results required. As shown diagrammatically brake 7 acts on wheel 6 having a cam 14 driving a scavenging pump 13 and a wheel speed sensor 9. When a critical value of wheel deceleration due to braking is detected, the control unit 10 energizes solenoid valve 11 to bleed pressure fluid into the "anti-lock" unit closing valve 22 as fluid passes into the reservoir 26 moving piston 24 to the left so that restrictor 27 enters the brake supply passage. When a suitable wheel acceleration is detected the solenoid valve closes allowing valve 22 to open and fluid is pumped back into the brake pressure line. An anti-lock unit may be provided for each wheel, or one for the front pair and one for the rear pair. Modifications. (i) The solenoid current may be used to vary the valve-loading (instead of opening it) so that it acts as a pressure relief valve causing a "tail-off" in pressure as the brakes are applied hard. (ii) The solenoid may control a two-way valve admitting fluid to a differential piston between the master-cylinder and the brake Fig. 2 (not shown); the connection pipes (4), (15), (20), going to the antilock unit as in Fig. 1. (iii) The differential piston may be replaced by a spring-loaded piston valve allowing a rapid increase of brake pressure to just under the locking valve when the wheel is released, Fig. 3 (not shown).

Abstract: 1329349 Cutting apparatus A FISHMAN 29 Dec 1971 [15 Jan 1971] 60600/71 Heading B4B A device for cutting sheet material comprises two cutting discs 28, 31, the disc 28 being mounted on a pivoted arm 22 thereby allowing the disc 28 to be moved towards the disc 31 in order to increase the overlap thereof and also enabling the material to be cut into by a shearing action when neither disc is rotating. The arm 22 is pivotally mounted on a pin 24 secured to a frame 13, 14, 15 on which the cutting disc 31 is rotatably mounted. The arm is urged to the normal position shown in Fig. 3 by means of a leaf spring 20. When it is necessary to start the cutting of thin material prior to the material being moved through the bight of the cutting discs, the arm is moved downwardly, so that the disc 28 cuts with a shearing action against the disc 31. The arm is then released and cutting continued with normal overlap. A two-part casing (1, 3), Fig. 1 (not shown), is provided. Resilient material guide lips (34, 35) are located at the entrance to the bight of the discs and an adjustable stop (37) is also provided.
