Abstract: 1,170,748. Moulding dough. THOMAS BARKER & SONS Ltd. 20 Feb., 1967 [20 Nov., 1965], No. 49397/65. Heading B5A. In apparatus for providing a substitute for " four piece " bread, a dough piece is fed by a conveyer to and is flattened, by elongation in a direction lengthwise of its direction of movement, by passage through a structure 13 containing three vertically spaced pairs of pinning rollers (not shown), interspersed with tapered width reducing shoots, and is then rolled up by grooved rollers and engaged between an endless travelling band 5 and a stationary flat surface 7, between guides 14, for conveyance therealong over a set of equally spaced rotatable circular knives 15 which project through slots 16 in the surface 7 to partially sever the dough roll to provide the desired " four piece " effect. The knives 15 may be rotated solely by frictional contact with the dough, or they may be rotated by a flexible drive (19) (Fig. 2, not shown). The knives 15 may pass through an edible oil lubricating bath (not shown). The surface 7 is suspended at pivots on arms 11, 11<SP>1</SP> carried by cross-shafts 10, 10<SP>1</SP>, the latter whereof is acted upon by a weighted chain to urge the surface 7 upwards towards band 5. Arms 12, 121 are also fixed to shafts 10, 10<SP>1</SP> and are interconnected by a lost motion connection comprising a rod 36, pivotally attached to the arm 12 at the inlet end of deck 7, and loaded by a spring 38 within a cylinder 37, which is pivotally attached to the other arm 12<SP>1</SP>. The knife shaft 18 is mounted in a fork 22 which is vertically adjustable to vary the projection of knives 15, via a rack-and-pinion gearing (24, 25) to a shaft (26) which is rotatable by a hand lever 27 locked in position around a rotatable quadrant 30 by a spring-loaded detent. The quadrant 30 is normally held against rotation by a pneumatic ram 34 actuated pawl (33). Upon delivery of an oversize dough piece to the inlet end of surface 7, this is depressed and the rod 36 is displaced relative to the cylinder 37 against the spring 38, whereby a lug 39 on rod 36 releases a microswitch 40 attached to the cylinder 37. The switch 40 actuates a solenoid valve 35 to release the pawl (33), whereby quadrant 30 rotates with shaft 26 and the knives 15 drop clear of surface 7 to avoid the dough piece.

Title: Control system for an impact device
IPC: B21J7/46
Filed: 1973-10-29
Abstract: 1428017 Automatic electric control CHAMBERSBURG ENG CO 29 Oct 1973 [30 Oct 1972] 50204/73 Heading G3N An impact device includes a ram driven by a piston and cylinder system. The force with which the ram is driven is controlled by adjusting the time for which a valve connects a constant pressure fluid supply with the cylinder of the drive system. As shown, a pneumatic high speed die-forging hammer comprises a ram 22 connected to a piston 18 in a cylinder 16. The ram is driven downwards by admitting air to the upper part of the cylinder 16 and is returned to its upper position by the pressure in a reservoir or surge tank 30. Air is admitted to the cylinder 16 by a main valve 42 connected through an inlet duct 38 with a supply 34 and adjustable pressure regulator 36. Main valve 42 is controlled by pilot valves 48, 52 and can be alternatively connected to an exhaust duct 44 and a restricted exhaust line used at the end of a sequence of operations. The upward motion of the ram 22 operates a switch 60 which opens valve 42 to begin admission of air, and also starts a timing relay which determines the time for which the valve remains open and hence the impact force. A desired sequence of impacts of predetermined force and number is set up on a manual control panel 68 having a series of rows of controls, each row corresponding to a given impact intensity and comprising an indicator light 78, switch 80 selecting up to fifteen blows each of the given intensity set by a ten-position switch 82, and a switch 84 which determines whether machine operation stops at the end of the number of impacts set by the row or continues as instructed by the next row. Operation is controlled by an electrical relay system, Figs. 5, 6 (not shown), the air inlet timing being set by potentiometers in RC charging circuits, and the number of blows of each intensity being counted by a binary counter with a display 80 which sets relays connected to the number of blows selector switch 80. When the desired number is reached, a relay actuates the restricted exhaust setting of valve 42, and the sequence is continued by operation of a foot switch 64 or automatically, as determined by the setting of switch 84.

Abstract: 508,489. Maleic anhydride. NATIONAL ANILINE & CHEMICAL CO., Inc. Dec. 30, 1937, No. 36169. Convention date, Jan. 13. [Class 2 (iii)] Maleic anhydride is produced by bringing solid maleic acid or a solution thereof (preferabTy of 25-75 per cent strength) into contact with a surface heated to about 160-400‹ C. so as to vaporize the acid quickly and produce a vapour of about 150‹ C. or more. The pressure may be 100-250 mm. or an inert gas may be employed to assist rapid vaporization. The reaction vapours may be treated with an inert organic liquid to absorb the maleic anhydride or may be cooled fractionally to separate first a small quantity of fumaric acid, and then maleic anhydride, leaving the water in the vapour state. To assist rapid vaporization, the solid, molten or dissolved maleic acid may be sprayed upon the heated surface which may be provided with a scraper to remove incrusted solid matter. Examples are given in which the initial material is maleic acid solution and maleic acid crystals respectively.

As shown holes 17 and 19, though which the eventual contacts to emitter 14 and collector 11 of a transistor are to be made, are fully open and a low resistance path between the conductor ends is provided by the same conductor material e.g. Si. Hole 18 does not extend to base 12 and the insulating material, e.g. SiO 2 , causes a high resistance between the conductor ends. The voltage applied during measuring should be sufficiently low so that no shunt current flows through the junction barriers. The holes may alternatively be for diffusion purposes.
