The phenylalkylsulphamide starting materials may be prepared by reacting a phenylalkylamine with sulphamide or a sulphamyl chloride. The phenylcyclopropylsulphamides are prepared by reacting an N-alkyl (or acyl)-phenylcyclopropylamine or the sodium derivative thereof with sulphuryl chloride followed by ammonia or the appropriate amine, and hydrolysing any trans - N - acyl - phenylcyclopropylsulphamide to remove the N-acyl group. Trans-N-formyl-2-phenylcyclopropylamine used as starting material in this process is prepared by reacting trans-2-phenylcyclopropylamine with ethyl formate. Trans - N - formyl - 2 - 4 - chlorophenylcyclopropylamine is similarly prepared. 4-Trifluoromethylphenethylamine is prepared by reducing 4 - trifluoromethylbenzoic acid with lithium aluminium hydride in ether, treating the resulting 4-trifluoromethylbenzyl alcohol with hydrobromic acid, then with sodium cyanide, and hydrogenating the resulting cyano compound.  N1 - methyl - N - phenethyl sulphamide and N,N1 - dimethyl - N - phenethylsulphamide are prepared by reacting phenethylsulphamide and N-methyl-N-phenethylsulphamide respectively with dimethyl sulphate. p-Acetoxyphenethylsulphamide is prepared by reacting p-methoxyphenethylamine with sulphamide, heating the resulting p-methoxyphenethylsulphamide with 37% hydrochloric acid and acetylating the p-hydroxyphenethylsulphamide produced.  Cis - 2 - (4 - chlorophenyl)-cyclopropylamine is prepared by refluxing cis-ethyl - 2 - (4 - chlorophenyl) - cyclopropane carboxylate with potassium hydroxide in aqueous ethanol, treating the resulting cis acid with diazomethane, refluxing the resulting methyl ester with hydrazine hydrate, diazotizing the hydrazide to give the cis-azide, which is rearranged by refluxing in methanol for five hours to give the methyl urethan which is hydrolysed by refluxing with a saturated methanolic solution of barium hydroxide octahydrate for 36 hours. Pharmaceutical compositions having central nervous system and anti-convulsant activity and which are useful for producing Parkinson-like symptoms in experimental animals contain as active ingredients compounds of the formulae given above.

[Also in Division H5] A laminated window is made by bonding together a layer of a flexible material and at least one layer of plastics material to form a flexible stratified construction, and subsequently bonding two outer sheets of glass or transparent rigid plastics material to opposite sides of the stratified construction. The flexible material may be polyethylene terephthalate, cellulose acetate, cellulose butyrate or polytetrafluoroethylene. The flexible material layer may be tinted and the colour density may be non-uniform. This layer may also be light-polarizing. It may be coated with a thin transparent layer, e.g. of gold, for reflecting infra-red radiation. This coating may be arranged for carrying an electric current for heating, in which case electrical leads to the coating may comprise silver flakes in an organic carrier applied either to the flexible material layer or to the coating. The plastics material layer may be of polyvinyl butyral. Two plastics material layers may be applied to opposite sides of the coated or uncoated flexible material layer. Such a stratified construction may be pressed between rolls, at least one set of which may be formed with contoured surfaces to impart a textured surface to the stratified construction. Adhesives may be used between the various layers. An assembly of the stratified construction and the outer layers of glass or transparent rigid plastics material may be made into the final laminate under heat and pressure or the assembly may be either pressed or placed in a vacuum bag to remove entrapped air and then placed in an autoclave to complete lamination.

A coating of heat seal resistant material 6, e.g. printing ink, is applied to one of a pair of heat sealable plies 1, 2 so that they adhere only along edges 8 and transverse strips 7 when heat and pressure are applied. Bags may be formed by cutting the united plies at 16a or a line of weakness, e.g. perforations or slits, may be formed there to aid subsequent separation of bags. The plies may be formed by folding a single web or from two separate webs. As shown, ply 1 is of paper coated with polyvinyl acetate, and ply 2 of transparent regenerated cellulose film coated with an ethyl cellulose or metal resinate as heat seal resistant material. The number of bags produced per unit length of the film may be increased by placing the coating so that further longitudinal seals are formed (Fig. 3, not shown) which are slit centrally. The transverse seals may also be slit centrally to form bags sealed along four edges, these then being divided into two bags each open at one edge.

Abstract: 1,036,639. Copying lathes. BIRMINGHAM SMALL ARMS CO. Ltd. Dec. 2, 1964 [Oct. 4, 1963], No. 39098/63. Heading B3T. A copying lathe having an automatic programme control comprises a preselector drum 3 (the Figure not shown) which is axially movable and rotatable through gears 2 by a rack 1 attached to the tool saddle 4. Cams 5, 16, 17 attached to the drum 3 operate a switch 7 to actuate a motor 8 to drive a control shaft 9 via gears 10. The shaft is rotated half a turn and the motor 8 is stopped by the actuation of a switch 12 by cam 11. During the half turn of the shaft 9 a second control shaft 13 is indexed by # of a turn by a Geneva mechanism 14. When the motor 8 is stopped by the switch 12 fast return travel of the saddle 4 is effected. The rotation of shaft 13 effects axial movement of the drum 3 by means of a lever 32 actuated by stepped cam 15. The return motion of the saddle 4 drives the drum 3 in reverse until cam 16 actuates switch 7 which recommences the feed traverse of the saddle. The feed and return traversing motion of the saddle may be effected from 1 to 4 times by the indexing of the drum 3 and is dependent on the collar 19 on the shaft 13, the axial location of the shaft being determined by grooves 35 and co-operating peg 34. The location of the shaft 13 affects the location of the collar and its projections 20 which determines the number of passes of the tool and saddle. The template 25 is mounted between centres on a frame carried on the machine and is movable in respect to the workpiece. The template mounting and operation is described in Specification 1,036,640.

Title: Video surveillance system, recorder and method
IPC: H04N5/783
Filed: 1969-08-12
Abstract: 1278108 Video recording MINNESOTA MINING & MFG CO 12 Aug 1969 [13 Aug 1968] 40319/69 Heading H4F A video recording system is arranged so that only every nth field is recorded on a recording medium which is moved past a rotating transducing head at 1/nth of the normal playback speed. The system may be used for surveillance. The recording mode is illustrated in Fig. 1 in which the video outputs of two cameras are gated under control of a timing circuit and recorded on a magnetic tape video recorder having a rotating head by means of which successive fields are recorded on oblique tracks. The recorder is provided with a low speed tape transport motor 108 which is clutched to the normal drive motor 112 during recording to advance the tape at a slow speed. The video signal gates are controlled so that one complete field is recorded on each oblique track. A sync. signal is recorded along the edge of the tape by means of head 42 and a servo system is provided for controlling the transducer rotation. In the replay mode, Fig. 2, the normal motor is used to move the tape past the head and a conventional replay system is used except that the transducer rotation is synchronized by means of signals derived from a video drum pulse head 144 which is nearly 180 degrees out of phase with the output of the normal servo drum pulse head 54. The resulting phase displacement of about half a track width corrects for the change of skew of the oblique tracks due to their being recorded with the tape running at a low speed. In an example a recorder with a normal tape speed of 7¢ i.p.s. is operated in the recording mode at a tape speed of # i.p.s. and every 60th field is recorded (i.e. one field per second). A stop motion facility is provided, the tape drive being stopped and the transducer head drive being synchronized from a 60 Hz source. A suitable gating circuit for the video signal is described with reference to Fig. 3 (not shown) by means of which selected complete fields are passed to the video recording head under control of a timing circuit and of the vertical sync. pulses. The low speed motor drives the normal motor during recording and this latter motor generates a signal which can be utilized to provide timing pulses for the gating circuit, Fig. 4 (not shown). A circuit for gating alternately two camera signals so that they are recorded on alternate oblique tracks is described, Fig. 5 (not shown).
