Title: Novel 2,6-Dimethyl-4-Phenyl-Piperazines and process for the manufacture thereof
Inventor: CIGNARELLA GIORGIO
IPC: C07D241/08
Filed: 1965-08-18
Abstract: 1,156,498. Piperazines. GRUPPO LEPETIT S.p.A. 21 July, 1966 [18 Aug., 1965], No. 35441/65. Heading C2C. Novel piperazines of the general formula wherein R represents hydrogen or a C 1-8  alkyl, aryl C 1-8  alkyl, cinnamyl or pyridylethyl group, are prepared by hydrogenating the corresponding 3-piperazinone with lithium aluminium hydride. The 3-piperazinones are prepared from α-bromopropionic acid by converting to α-bromopropionyl chloride, forming the corresponding anilide, replacing the bromine atom by an amino group and reducing to give α- aminopropylaniline. This compound is then treated with ethyl α-bromopropionate to give N - 1 - (2 - phenyl - aminoisopropyl) - alanine ethyl ester, which is heated to give 4-phenyl- 2,6 - dimethyl - 3 - piperazinone and a suitable group is optionally substituted in the 1-position. Pharmaceutical compositions comprising, as active ingredient, a piperazine of the above general formula together with a pharmaceutically acceptable carrier are useful for the therapeutic treatment of hypertension.

An educational device includes a multistage counter, a selector dial for entering numbers into the counter and a set of endless belts coupled to respective stages of the counter and passing below windows in the casing of the device. The belts carry digital symbols whereby a number entered in the counter is represented pictorially by the symbols displayed in the window. The device consists of a dial 3 driving a wheel 19 through bevel gears. The wheel 19 has a ring 20a carrying the numerals 0-9, 0-9 visible through a window 6 and a knurled end 20 projecting through the casing 1. In addition, the wheel 19 drives an endless belt 23 through co-operating pins and apertures 22. The belt carries two lines of unit symbols 27, 28 visible through a window 4. A shutter 29 movable laterally by a pivoted lever under the control of a cam surface on the wheel 9, covers each line of symbols 27, 28 in turn and is moved as the wheel passes between 9 and 0. A second wheel 39 driven by a transfer-mechanism as the wheel 19 moves between 9 and 0, has a ring 40 bearing numerals visible through a window 7 and drives an endless belt 44 having one line of tens symbols 46. The transfer-mechanism comprises two diametrically spaced, spring-loaded pins projecting from the wheel 19 which are moved radially inwardly by a fixed cam to engage a gear fast with wheel 39 and move it step-bystep. A disc 2 beneath the dial 3 bears two sets of numerals 1-10 and is movable to display one or other set through finger holes in the dial under the control of lever 9 setting the calculator for addition or subtraction. A finger stop 10 is displaced to position 11 or 12 against a spring on entering a numeral. In use, a series or numbers to be added or subtracted are entered by dial 3 (or by knurled wheels 20, 41) and the answer displayed numerically in windows 6, 7 and graphically as a series of unit and tens symbols in windows 4 and 5. The calculator includes a paper roll visible through can opening for recording a question- and-answer. A transparent cover is movable to .cover-the paper roll and is interconnected with a shutter movable to close windows 6, 7, Fig. 7 (not shown). Alternatively, the calculator carries a slate and a shutter movable by a hand grip to cover the windows 6, 7.

Abstract: 789,708. Road-traffic signals on vehicles. FISCHERSTROM, N. C. H. Dec. 23, 1955 [Dec. 23, 1954], No. 36885/55. Class 118 (2). A traffic signalling arrangement for vehicles comprises a lamp shining forwardly to indicate right of way to crossing traffic or pedestrians and a lamp shining rearwardly to warn following traffic, the lamps being controlled by a common switch within reach of the driver, wherein both lamps also throw some light towards the driver such that he may observe their functioning at a glance. The rear warning lamp is arranged to be observable in the rear view mirror and is preferably yellow and located immediately inside the rear window of the vehicle. The forward indicating lamp is preferably green and located adjacent the rear view mirror thereby being readily seen by the driver as he looks in the said mirror. The rear warning preferably comprises two lamps 5 one above the other connected via a device 37 which when energized flashes the lamps 5 alternately. The control device 15 comprises a push-button 27 which when partially depressed connects battery 31 to a pivoted spring-loaded lever 21. and thence via a contact 33 and switch 41 to the flasher 37 and lamps 5. On further depression of button 27 to overcome the action of spring 43 the circuit to the flasher 37 is broken at contact 33 and contacts 17, 18 are energized. This causes the forwardly shining lamp 1, situated adjacent the rear view mirror 3, and the rearwardly shining lamps 5 to be steadily illuminated. Instead of two separate lamps 5 a special lamp may be used, for example, of triangular shape.

In a direct-call system in which connections are set up over the home line of the called station, each substation is provided with a loudspeaker H which serves as both transmitter and receiver, and with two one-way transistor amplifiers F1 and F2, the polarity connected up by the calling station controlling the effective transmission direction of its own and the called station's amplifiers. The system described caters for three identical stations T1, T2, T3, of which only T2 is shown in full and T1 in part. To call T1, the party at T2 sets his selector LV on contacts 1 whereupon if station T1 is busy, lamp UB lights to the potential connected to L1 by T3 (the calling station). If T1 is free, the caller depresses key JK, thus connecting negative potential to L2 to mark T2 busy, feeding positive potential over a contact of TK to the emitter of F2 and to the collector of F1, and feeding negative potential over another contact of TK to the emitter of F2 and the collector of F1 in the called station Tl. Transistors F2 of T2 and F1 of T1 are thus enabled and speech may be transmitted from T1 to T2. This path may be disabled if desired by the operation of the secrecy switch SS of T1. Depression of talk button TK in the calling station T2 reverses the polarities fed to the transistors and changes over the transmission direction. Release is effected by a disconnect button (not shown) which restores the contacts of JK to normal.
