Title: Random access memory systems
IPC: G06F12/16
Filed: 1975-05-21
Abstract: 1481373 Error correction INTERNATIONAL BUSINESS MACHINES CORP 21 May 1975 [18 Aug 1974] 21871/75 Heading G4A In a random access memory system including error correction means, each stored data word includes a plurality of check bits used to correct a single bit error in the word and indicate the presence of multiple error, such multiple error in two (or more) words being corrected with the aid of two (or more) additional stored words, each byte of each of the two additional words having been formed by bit-wise modulo-2 addition of the corresponding bytes of the data words (after, in the case of the second additional word, multiplying each of the bytes by a respective power of the companion matrix of a primitive binary polynomial of the code). Syndrome bits are derived from each data word (including its check bits) to indicate error/noerror and decoded by ANDs to indicate singleerror/multiple-error (in conjunction with the error/no-error indication) and locate single error (if present) for correction. Two "accummulators" also receive the words to derive syndromes from which multiple errors in up to two (or more) words are corrected using the output of the previous circuitry to indicate which words have multiple errors. The memory holds a plurality of blocks of words, each block being 16 data words (with check bits) and the 2 (or more) additional words relating to them, the blocks being stored on multi-array wafers such that each block is spread over 4 wafers, 4 data words per wafer with each half data word being in a different array, and the additional words being in different arrays from the data words.

Title: Improvements in or relating to methods of and apparatus for nut cracking
IPC: A23N5/00
Filed: 1938-07-27
Abstract: 517,433. Cracking nuts. JONES, K. M. July 27, 1938, No. 22334. Convention date, Aug. 7, 1937. [Class 59] [Also in Group I] A method of extracting kernels from cohune &c. nuts comprises cooling the nuts to a temperature below about 33‹F. and then shattering the shells by either impact or pressure deformation. As shown in Fig. 1, nuts are fed in batches or continuously through a gas-tight feed valve 4 into a container 2 surrounded by a jacket 6 for the circulation of cooling liquid such as brine from a partitioned tank 12 connected to a refrigerator 14. The liquid may be cooled to a temperature between 0‹ and 20‹F. and may be circulated through the jacket by a pump. The nuts may be cooled by the circulation of a cooling gas or the two methods may be combined. The gas may be cooled in the coils of a pipe 20 inserted in the tank 12 and forced by a pump 22 through an expansion nozzle 26 into a mixing chamber 30 where it combines with gas which has circulated through the nuts in chamber 2 and is returned through pipes 40, 24. The temperature of the gas is controlled by valves 42, 44 in the pipes 24, 20 respectively. The lower part of the chamber is closed by a grid 34 and valves 35 through which the cooled nuts are discharged into the expansion chamber 30 through a gas-tight valve 38 and are fed on to cleats 53 on a belt 52, Fig. 2, from which they drop and are struck by rotary beaters 56. The impact of the beaters breaks the nut and projects the shell and kernel on to a cloth screen 57 from which they fall on to an apron 69 and screen 70, the kernels and small shell falling through the meshes of the screen 70 on to a further screen 76. The kernels on the screen 76 roll on to an inclined belt 90 and fall off or are blown off by an air jet 92 into a receptacle 96, the parts of the shell which do not pass through the screen 76 for further screening at 78 adhere to the belt 90 and drop into a shoot 97. The nuts may be crushed between two rollers on parallel arcs, one roller being cylindrical and the other conical, whereby the nuts are sized before passing through the rollers.

Title: Improvements in or relating to controlling devices for fluid pressure brakes
IPC: B60T15/04
Filed: 1938-07-30
Abstract: 517,585. Fluid-pressure brakes. BOSCH GES., R., (formerly BOSCH AKT.-GES., R.). July 30, 1938, No. 22737. Convention date, Aug. 2, 1937. [Class 103(i)] In a valve device for a fluid-pressure brake system comprising main and auxiliary valves suitable for the control of the brakes of a tractor and a trailer vehicle respectively and operated by a common lever the auxiliary valve casing is detachably secured to that of the main valve which is secured to the tractor vehicle or other support. The tractor valve body 10 is secured by bolts at 13 to the vehicle and the trailer valve body 16 is bolted to the body 10. The tractor valve comprises a pis'ton 31 with a tubular part 32 which is normally unseated from a supply valve 33 to connect the chamber 30, connected by passages 38 to the tractor - brake cylinders, to chamber 50, which is open to atmosphere. The trailer valve comprises a similar piston 31<1> carrying a tubular part 32<1>. normally urged by a tubular rod 42 under the action of a springs 40, to unseat the supply valve 33<1> to connect the trailer brake cylinder pipe 17 to the supply reservoir pipe 11 through passages 27; 27<1>. A floating lever 21 linked to the pedal 23, is connected by a lever 25 and push rod 19 to the piston 31 and to a rod 20 between which and the rod 42 is a spring 43. When the pedal is operated the rod ,42 is first moved to the left compressing spring 40 and permitting the piston 31<1> to close the supply valve 33<1>, the part 32<1> leaving the valve to allow the compressed air from pipe 17 to exhaust to atmosphere through the part 32<1> and passages 44, 45. When after the application of the trailer brakes has thus commenced, the pedal pressure becomes sufficient to move the piston 31 against the action of the spring 35 and the reservoir pressure on the valve 33 this valve is lifted by the tubular part 32 to supply the tractor cylinders. If the pedal is held in an intermediate position, the pistons 31, 31<1> due to the pressure increase and dedrease respectively acting on them are returned to a lap position in which both the valves are seated and the parts 32, 32<1> are seated on the valves. The lead in the operation of the trailer valve relatively to the tractor valve can be adjusted by varying the point of connection 22 of the pedal to the lever 21. When the trailer valve device 16 is detached, a component. 16<11>, Fig. 3, having a spring 43" and rod 20" for connection to the lever 21, is substituted, the spring acting in the same manner as the spring 43. The component blanks off the supply passage 27.

Title: Improved support assembly for turbine casings
IPC: F01D25/28
Filed: 1955-08-08
Abstract: 780,392. Turbines. GENERAL ELECTRIC CO. Aug. 8,1955 [Aug. 11, 1954], No. 22811/55. Class 110 (3). An. elastic fluid turbine in which the casing is supported from pedestals carrying the rotor shaft bearings has wedge plates attached to the casing and pedestal respectively with the oppositely inclined surfaces of the wedge plates parallel to one another and a key plate located between the wedge plates which lies substantially in a radial plane through the centre line of the turbine shaft. A turbine casing is supported on two pedestals 2 carrying the bearings 3 of the rotor shaft 1. One of the pedestals is fixed to the foundation 4 while the other is free to slide axially on a sole-plate secure to the foundation. The casing is supported on the pedestals by arms 7, 8. The arms 7 rest freely on the arm 8 which is clamped to the pedestal 2 by a bolt 9, nut 15 and sleeve 14. The upper arm 7 is freed to expand vertically without stretching the bolt 9. The holes 10, 11 in the arms are substantially larger than the bolt 9 to allow for relative movement of the arms 7, 8 and the pedestal 2. Expansion of the lower half of the casing is allowed in a radial direction by a support assembly B, Fig. 4, so that there is no tendency for the casing to expand upwards and so damage the shaft packing. The assembly B comprises two wedge plates 16, 17 and a key plate 18. The wedge plates are attached by screws to the casing and pedestal respectively and located thereon by bosses 19, 22 which engage recesses 20, 23. The key plate 18 is a flat plate having spigots 27, 28 which engage recesses 31, 32 in the wedge plates. The sloped surfaces 25, 26 of the wedge plates are parallel to one another and when the key plate is inserted it lies in a radial plane through the centreline of the shaft 1. The spigots 27, 28 lie in a plane perpendicular to the axis of the turbine so that axial movement of the turbine relative to the wedge plates is prevented whilst allowing radial movement of the arm 8 relative to the shaft 1. To prevent transverse movement of the casing, a lug 36, Fig. 5, on the casing fits into a recess 39 in the pedestal 2. Packing pieces 38 are also provided. Plate 18 may be used as a packing-piece to align the shaft with the casing. The wedge plates may be hardened and the key plate left soft or vice versa and may be made of expensive material to prevent galling and allow of free sliding. In a modification, the upper arm 7 is omitted. In a further modification, either or both of the spigots 27, 28 is on the wedge plates.
