Filed: 1935-07-08
Abstract: 447,585. Ironing presses. JOTTNSON, G. W., 1750, Northcutt Avenue, Cincinnati, Ohio, U.S.A. July 8, 1935, No. 19525. [Class 138 (ii)] Operation of the manuals 54, 55 of one press A to pass fluid pressure from the supply pipe S through pipes 52, 53, 19 to the cylinder 16 of that press for closing the same, simultaneously passes the fluid pressure through a pipe 49<1> to a cylinder 451 so that a piston 46<1> therein moves to rock a bell-crank lever 48<1> counterclockwise. This bell-crank forms part of the pedal 38<1> for opening an adjacent press B so that the latter is opened automatically by the fluid pressure controlled from press A instead of by the operator actuating pedal 38<1> of press B. The pedal is linked to a bell-crank 42<1> which, on being swung counter-clockwise, opens the cylinder 16<1> to exhaust through ports 23<1>, 27<1> so that the spring 14<1> opens the press. Simultaneously the bell-crank 42<1> rocks a three-armed lever 31<1> about its pivot 441 so that one arm 321 thereof moves away from a valve stem 33<1> to enable a spring 35<1> to close this valve and shut off the supply of fluid pressure to the cylinder 161 through pipes 36<1>, 37<1> which valve was opened, when the press B was safely closed, by the cam bar 28<1>, moving with the piston rod 18<1>, coacting with a roller 30<1> on the lever 31<1>. This supply being in parallel with that containing the manuals 54<1>, 55<1>. Similarly the closing of press B is accompanied by the opening of press A. If it is desired to prevent the automatic opening of one press simultaneously with the closing of the other press, a manual 59 adjacent one of the press-closing manuals on such other press is actuated to close a valve 58 and shut off the supply of fluid pressure to the pipe 49<1>.

A capsule of thermoplastic material has opposite parts of its wall brought together without being welded to each other, so as to divide it into two compartments separated by a weak seal which can be overcome without bursting the capsule, by manually squeezing one of the compartments. As shown, a tube 10 of thermoplastic material is heated and pressed at each end to form a strong seal 12. The capsule is divided into two compartments 20 and 22 by a transverse weak seal 14 formed by pinching opposite parts of the wall together with a membrane 16 e.g. of paper between them. When the capsule is squeezed the membrane 16 splits, the weak seal 14 is broken, and the contents of the compartments can be mixed before the capsule is opened. In a modification, Fig. 4 (not shown), a similar capsule has a weak seal at one end in place of the strong seal previously shown. The capsule of Fig. 6 has two tubes 10 and 11, one within the other, joined at one end by a common strong seal, and provided at the other end with a weak seal 14. The three-compartment capsule of Fig. 7 has strong seals 12 at each end, and an intermediate transverse weak seal 14. Additionally a weak seal 14 extends from one of the strong seals 12 to the intermediate weak seal 14. In a modification, Fig. 8 (not shown), the seal separating the compartments 22 and 23 of Fig. 7 is a strong seal instead of a weak seal. In Fig. 9 (not shown), a capsule has a tube-like portion 24 formed with a neck 28 surrounded by a cup portion 30, and separate spherical portion 26 having a slit 32 as a weak seal rests in the said cup portion 30. The two compartment capsule may be provided with a withdrawable pin or rod extending from one end of the capsule into the intermediate seal which is formed around the said pin or rod. The capsules may be of gelatine, rubber or synthetic resin e.g. polyvinyl chloride. The membrane of the weak seal must be a non-absorbent for the contents of the capsule. Once the weak seal has been overcome the capsule contents may be mixed using a simple electric coil vibrator, mains driven, and provided with a vibrated arm formed with, or having attached thereto, a clip or other holder or receptacle for one or more capsules.

Title: Data Transmission
IPC: H03M13/43
Filed: 1968-04-26
Abstract: 1,168,032. Data storage; error correction. INTERNATIONAL BUSINESS MACHINES CORP. 26 April, 1968 [8 May, 1967], No. 19807/68. Headings G4C and G4H. A decoder for decoding a message consisting of signals representing the results of logically combining data items in groups in such a way that each item is used m times in producing the message but no item is used more than once in obtaining any particular result, comprises means for logically combining the result signals to obtain m manifestations of each data item which are fed to majority logic to reconstitute the items. Five data bits are EXCL-ORed in groups (each of which includes the fifth bit) in an encoder to obtain 14 bits which, together with the fifth bit unmodified, constitute a message which is transmitted, or written into a store. When received, or read out from the store, the message bits are EXCL-ORed in groups in a decoder to obtain 7 versions of each of the first four data bits, majority (threshold) logic then obtaining the majority value for each data bit from the 7 versions. A majority value for the fifth data bit is obtained similarly from 7 versions, one of which is the "unmodified fifth bit" as included in the message and the others are obtained by EXCL-ORing message bits with each other and with the majority values for the first four data bits. Each data bit contributing to any EXCL-OR combination in the encoder contributes only once to that combination. Each data bit contributing to any EXCL-OR combination in the decoder (including indirect contribution via message bits) contributes an even number of times to that combination (and so cancels out) except for one data bit in each case. In this way up to 3 bit errors are corrected. Analogous codes are described dispensing with one or two of the input data bits. These do not use the feedback associated with the fifth bit since this has been dispensed with in both cases. In the second case, some message bits are copies of others.
