Title: Apparatus for the comminution of coking breeze
Inventor: SCHULZ ERICH
IPC: B02C4/02
Filed: 1955-07-18
Abstract: 780,780. Roller mills. SCHULZ, E. July 18, 1955 [Aug. 11, 1954], No. 20753/55. Class 59 A crusher for comminuting coking breeze comprises smooth grinding rollers 4, 12 which are spaced apart a distance which is determined by an adjustable hollow spindle 24, Fig. 2, against the lower end of which abuts a spring-influenced crossmember 23, the rollers 4, 12 being rotated at a peripheral speed which is greater than the speed of fall of material from a feed hopper 32 extending along the length of the grinding gap. The shaft 13 of the roller 12 is mounted in bearings 14 connected to pivotally-mounted bell-crank levers 15 are connected together by a cross member 16 to which is pivoted at 19 an adjustable lever 18. The upper end of the lever 18 is formed by the cross-member 23 against which bear the upper ends of compression springs 21 the lower ends of which bear against a cross-member 40 which is vertically adjustable by means of a screwthreaded spindle 22 extending through the hollow spindle 24 of a hand wheel 20. The spindle 24 extends through a nut 38 hingedly mounted in bearings 39 fixed to a frame 1. The bearings 2 of the shaft 3 of the roller 4 are mounted on a cross-member 7 pivotally mounted on pins 8 on two longitudinal supports 9 of the frame 1. The cross-member 7 is traversed at its other end by an axially-adjustable shaft 10. The side walls 29 of a housing 28 surrounding the rollers 4, 12 are axially adjustable by means of set screws 30 corresponding to the axial position of the roller 4. The rollers 4, 12 are driven by means of electric motors 5, 26 through belt and pulley drives. The comminuted material passes through an outlet hopper 35 on to a conveyer belt 36.

Title: Improvements in or relating to information checking systems
Inventor: WOODHEAD JAMES
IPC: G06K5/00
Filed: 1957-07-02
Abstract: 855,201. Electric selective signalling systems. INTERNATIONAL COMPUTERS & TABULATORS Ltd., May 20, 1958 [July 2, 1957], No. 20848/57. Class 40 (1). Apparatus for checking translated information comprises first means settable to register any one of a plurality of different characters represented according to a first code, first codetranslating means operable in response to the registration of a character by said first registering means to produce an output representation of such character according to a second code, second registering means settable in response to the said output to register the said representation according to the second code, second translating means operable simultaneously with the first code translating means in response to the registration of the character representation by the first registering means to produce an output representation in a third code of a feature of the character representation according to the first or the second code, third translating means operable in response to the registration of the character representation by the second registering means to represent a like feature in the third code and checking means responsive to the second and third code translators to indicate whether the two representations in the third code are identical or not. In a device for checking the punching of record tape from a keyboard a depressed key 0 to 9, Fig. 1, energizes a corresponding combination of punch magnets P1 to P5 and also energizes one of two lines 14, 15 depending upon the parity of the number of punch magnets that should be energized, and those punch magnets actually energized change over associated contacts P1a P1 to P5a, P5b, whereby if the number of punch magnets actually energized is the same as the number that should be energized (i.e. if no error is present) then a relay R3 is energized whereas if these two numbers are not the same a relay R4 is energized. The detailed operation is as follows: Initially a start key ST is depressed to energize a relay R2 which then holds via its contact R2a. Depression of a key then energizes one or more punching magnets which initiates a punching cycle early on in which a cam-controlled contact PC opens. At this stage if relay R3 has been energized relay R2 remains energized via contact R3a and the actual punching occurs towards the end of the cycle or if relay R4 has been energized contact R4a opens, causing relay R2 to fall-out which, via its contact R2b, causes the punch magnets to be de-energized and no punching is effected. In a modification (Fig. 2, not shown) the leads 14 and 15 are replaced by three leads to give a more positive check.

Title: New and improved solder and a process of manufacture thereof
IPC: B23K35/28
Filed: 1951-09-10
Abstract: A Zn-Sn solder is made by heating commercially pure Zn to a temperature between 475 and 625 DEG C., allowing it to cool to a temperature between 425 and 525 DEG C. and adding commercially pure Sn at this temperature, slowly heating the melt to a temperature between 525 and 675 DEG C., thoroughly mixing the constituents and cooling the melt rapidly.  In an example, 9 parts of zinc are heated to 550 DEG C. and maintained at this temperature for 15 minutes, after which it is cooled to 450 DEG C. at which temperature 1 part of Sn is added to it.  The melt is then slowly heated to 600 DEG C., stirred thoroughly and poured into a water-cooled book-type mould. The solder may be used for aluminium, aluminium alloys, zinc-based die-cast metals and pewter (see Group XXII).

Release springs 51 are positioned between the pistons and removable abutments 52 held in position by split-rings 53. An eye-bolt 58 on the top of the motor casing is loosely connected by a link 61 to a bolt 59 in lugs 60 on the transom, so that in the event of the failure of its spring support the motor is prevented from falling on to the tracks. These safety means may be supplemented by similar means 63, 62, 64, loosely connecting each brake cylinder to the transom. A rubber buffer 65 prevents metal-to-metal contact between the motor casing and the transom. Manually operable means 67, 68, 69 for applying the brakes may be provided.

[Also in Groups XXXIII and XXIX] In a system, as in the parent Specification, in in which a main hydraulic servomotor actuating a control surface of an aircraft may be automatically or manually controlled through an electrical control system, or manually controlled through a mechanical control system, a spring- loaded yieldable coupling is added between the manual controller and the artificial feel device associated with it so that, if sufficient force is applied to the manual controller during electric automatic control, the coupling yields and opens a switch to change over the system to mechanical control. This yieldable coupling is additional to that provided in the parent Specification which requires more force to operate it since the artificial feel device must be operated with it. The switches associated with the two yieldable couplings are connected in series. The switch associated with the additional yieldable coupling is shorted during electric manual control to prevent changeover. Specification 803,574 is referred to.
