Inventor: WESTLAND ROGER DEAN
IPC: C07C271/22
Filed: 1953-03-20
Abstract: The invention comprises O-haloacetyl-N-carbobenzoxyserine compounds of the general formula <FORM:0744586/IV(a)/1> (wherein X represents a halogen atom, B represents hydrogen, an alkali metal or one equivalent of an alkaline-earth metal, and R1 represents a benzyl radical, which may be unsubstituted or substituted, e.g. by halogen atoms or alkyl, alkoxy, amino or nitro radicals in the nucleus and/or by alkyl or phenyl radicals in the side chain), and the preparation thereof by reacting an N-carbobenzoxyserine with a haloacetyl halide or haloacetic anhydride, followed, if desired, by treatment of the product with an alkali or alkaline-earth metal hydroxide, carbonate, bicarbonate, oxide, alkoxide or amide.  The main reaction is advantageously carried out below 125 DEG  C. in a non-hydroxylated organic solvent, and may be catalysed by concentrated sulphuric acid or by a tertiary amine, the temperature in the latter case preferably being between 0 DEG  and 25 DEG  C.  Examples describe the interaction of: (1) bromoacetyl bromide and N-carbobenzoxy-dl-serine in benzene and ethyl acetate in the presence or absence of triethylamine; (2) chloroacetic anhydride and N-carbobenzoxy-dl-serine in ethyl acetate in the presence of concentrated sulphuric acid; (3) bromoacetyl bromide and N-carbobenzoxy-l-serine in ethyl acetate in the presence of triethylamine; (4) chloroacetyl chloride and N-carbobenzoxy-l-serine in ethyl acetate in the presence of pyridine.

Title: Hydraulically actuated friction clutch
Inventor: ASCHAUER GEORGE REISCH
IPC: F16D25/0638
Filed: 1957-11-07
Abstract: 848,823. Friction clutches; gearing for stopping and starting machinery. TWIN DISC CLUTCH CO. Nov. 7, 1957, No. 34763/57. Class 80 (2). A multi-disc friction clutch between a driving (or driven) shaft 10 and a driven (or driving) member 15 is engaged by supplying oil under a relatively high pressure to a space 24 between a flange 21 fast upon the shaft and an axiallyslidable surrounding cylinder 22, 23, 29 thereby slidden leftwards of Fig. 1, disengagement being effected by releasing the pressure in the space 24 so that oil continuously supplied at a relatively low pressure to a space 34 on the other side of the flange becomes effective to slide the cylinder 22 rightwards, a passage 38 and restriction 40 supplying oil at all times from the low-pressure clutch disengaging space 34 to the inner periphery of the friction discs which are thereby lubricated and cooled. In the form shown, the low-pressure oil for clutch disengagement is supplied through passages 56, 28, 26 to the space 24, and the high-pressure oil for clutch engagement is supplied through a pipe 52, 35 and a space 31 leading to the space 34.. In one modification, Figs. 3, 4 (not shown), a similar multi-disc friction clutch is illustrated mounted at the centre instead of at the end, of a shaft, and the oil for clutch engagement and disengagement is supplied through two pipes arranged on diametrically opposite sides of the shaft. In another modification, Fig. 6 (also not shown), the oil for clutch engagement and disengagement is supplied through central passages in the shaft, one leading from one end of the shaft and the other from the opposite end of the shaft. Oil is supplied under pressure to the clutch from a pump 42, Fig. 5, whence it is supplied to a piston valve 45 which, in the position shown, passes oil only to a pipe 47 and a pressureregulating valve 48 which maintains a relatively high pressure. A pipe 49 leads the oil off to a pipe 52 and a second pressure-regulating valve 50 which maintains a relatively low pressure, oil from the second regulating valve 50 returning via a pipe 51 to a sump 43. The pipe 52 leads to the clutch disengaging space 34 and to the inner peripheries of the friction discs. Accordingly, with the piston valve 45 in the position shown, oil is supplied at the low pressure determined by the pressure-regulating valve 50 to the space 34 &c., and the clutch is disengaged. By sliding the piston valve 45 to the right, the pump 42 is connected directly to the pipe 56 leading to the clutch-engaging space 24, to which oil is supplied at the relatively high pressure determined by the pressure-regulating valve 48.

A piston ring or seal 25 for the master cylinder of an hydraulic brake system is made of resilient material and comprises pairs of inner and outer lips forming a cross-section which is H-shaped. As shown, a rubber seal 25 of H- section is retained in the cylinder by a washer 9 and spring clip 10, the pair of inner lips 8, in contact with the piston, forming a channel which is filled with grease. The piston is returned by a spring 17 and a thrust ring 21 cooperates with the end of a bush 3 to displace a valve ring 18 against the action of a spring 22 so as to connect the cylinder chamber 19 with a reservoir through a connection 24. In Fig. 2 (not shown), a piston ring (170) of H-section is seated in a piston groove (200). During the return stroke in this embodiment, a groove (150) in the piston adjacent a valve ring (101) registers with an opening (140) in the cylinder for connecting the cylinder chamber (500) with the reservoir, a pressure compensating hole (160) being provided in the cylinder.

[Classes 39 (i) and 40 (iii).] In a Braun tube for television receivers, the cathode ray is concentrated, electrostatically controlled in its intensity and concentrated again so that its position and direction are maintained constant. The received signals amplified at 13 may be led over a condenser 14, to terminal 15, so biassing the concentrating Wehnelt cylinder .3 to control the intensity of the cathode ray which is further concentrated by the preferably cylindrical electrode 6 before being deflected by the scanning electrodes 7, 8 over the screen 9. Alternatively, the signals may be fed to the terminal 16, biassing the electrode' 5 to deflect the cathode ray stream to pass, to a varying degree, through the aperture in the anode 4. Preferably, only the anode is of magnetic material and the irregularities of the Wehnelt cylinder- 3 are compensated by magnetizing the anode. By suitably biassing the electrode 5 from the potentiometer 11, high frequency signals may be used without rectification ; the bias potential is such as to deflect the cathode ray stream to miss the aperture in the anode 4 when the modulation of the high frequency carrier is at a maximum (or minimum). According to the Specification as open to inspection under Sect. 91, the electrode 5 may be replaced by a pair of deflecting plates transformer coupled to the amplifier 13 (Fig. 4, Cancelled, not shown). This subjectmatter does not appear in the Specification as accepted.
