Title: Novel propane derivatives and a process for the manufacture thereof
Inventor: BRUST BERNARD
IPC: C07D211/12
Filed: 1966-06-17
Abstract: Novel 2 - isopropyl - 1,3 - di - [piperidyl-(4)]-propane and acid addition salts thereof are prepared by dehydrating a propanol-(2) compound of the general formula <FORM:1106028/C2/1> wherein A and B may each be a pyridyl-(4) or piperidyl-(4) group, or an acid addition salt thereof, in the presence of a mineral acid, hydrogenating the resulting propene-(1) compound of the general formula <FORM:1106028/C2/2> in the presence of a noble metal catalyst and, if desired, converting the hydrogenation product into an acid addition salt. When A and/or B are pyridyl-(4) groups the hydrogenation procedure may be carried out in two steps, using palladium, platinum or Raney-nickel as catalyst for hydrogenation of the olefinic double-bond and platinum in hydrochloric acid or rhodium in ethanol for the hydrogenation of the pyridyl-(4) group to a piperidyl-(4) group, or simultaneously using platinum in hydrochloric acid or rhodium in ethanol.  Alternatively, a propanol-(2) of the first general formula may be converted directly to the novel propane compound by use of a hydrogenation catalyst and an acid, for example platinum in hydrochloric acid.  Propanol-2 compounds of the first general formula above may be prepared (a) when A and B are each a pyridyl-(4) group, by reacting a [picolyl-(4)]-(alkali metal) compound with an isobutyryl halide or an ester of isobutyric acid, (b) when A is a piperidyl-(4) group and B is a pyridyl-(4) group, by reacting a [piperidyl-(4)]-methyl isopropyl ketone with a [picoly-(4)]-(alkali metal) compound.  Pharmaceutical preparations containing the novel propane derivatives in admixture with a compatible pharmaceutical carrier are useful as cardiovascular agents, also possessing anti-depressant activity.

Abstract: 1327575 Shift register INTERNATIONAL BUSINESS MACHINES CORP 19 April 1971  [16 April 1970] 27188/71 Heading G4C A shift register comprises a set of bistable devices for each stage, and logic circuits effective during shift cycles to control the shifting of data through the stages so as to prevent the shifting of data from one stage when the next succeeding stage is storing data, to allow the shifting of data through a group of successive empty stages to an empty stage, and to select the number of stages in the group. Each bistable device is a polarity hold latch which, when set, stores the datum existing at its input and, when reset, transfers the datum existing at its input directly to its output. The register is adapted for use as a data buffer for communication between a processor and a number of peripherals (e.g. magnetic discs) on a priority interrupt basis. Data is received on a bus CHIBI which carries eight data bits and a parity bit. The data is fed into the input stage GR and is fed out of the output stage G0 having passed through buffer stages B0-B6. The logic control circuit includes a number of stages GRF-BFO which indicate whether their associative storage stage is full or empty, latches GRP-BPO which determine to which positions data are to be transferred, and gates SD6-SD0 which cause data to be latched into respective stages of the register. In the preferred embodiment the number of empty stages through which data may be transferred is two.  The buffer may be partitioned into two sections to enable input and output operations to be performed on respective sections. A counter is provided to determine when the register becomes full. The specification describes the gating and circuit arrangements in some detail.
