Abstract: 1,238,873. Feeding sheets. RICOH K.K. 28 Aug., 1968 [31 Aug., 1967], No. 41005/68. Heading B8R. A pile table 2 for a stack of sheets 3 is raised by a pawl 19, reciprocated through an eccentric pin 21 by a wheel 20 rotated from a sheethandling machine, and intermittently rotating a ratchet wheel 17 which rotates a pinion 18 engaging a rack 15 on a plate 11 fixed to the table. A spring 23 normally raises a plate 22 to hold the pawl clear of the ratchet wheel. When a solenoid 25 is energized by closing a microswitch 34 responsive to a fall in the level of the top of the stack, sensed by a roller 33, the plate 22 is lowered to engage the pawl. When a rod 29 is raised manually, a locking pawl 28, which normally prevents reverse rotation of the ratchet wheel, is released and a microswitch 32 is opened to de-energize the solenoid, so that the table is free to fall to its lowest position. Original sheets are fed to a photocopying machine on a belt 7 and the leading edge of each sheet closes a microswitch 8 to activate a separator roller 4 and feed a copy sheet from the stack along a belt 10 to be passed into the machine with the original. In another form, the solenoid 25 and plate 22 are omitted, the pawl 19 is in permanent engagement with the ratchet wheel, and the sensing roller 33 controls the drive to the wheel 20.

Abstract: 1,239,418. Anti-skid control of brakes. KELSEY-HAYES CO. 30 Aug., 1968, No. 41625/68. Heading F2F. In anti-skid vehicle braking system an angular accelerometer 16 is provided for sensing electrically angular acceleration of a wheel of the vehicle and a linear accelerometer 17 is provided for sensing electrically the linear acceleration of the wheel the signals provided being fed through amplifiers 18, 19, 21 and summing amplifiers 20, 22 to produce a first electrical signal representing the rate of change in braking force on the wheel as a function of the time dF/dt for producing a second electrical signal representing the rate of change in the slip of the wheel as a function of time dS/dt the signals are being fed into level amplifiers 24, 25 to a gating logic circuitry 26 for producing a control signal for reducing the braking force on the wheel to be braked when the polarities of the first and second signals are different and for maintaining the braking force on the wheel to be braked when the first and second signals have the same polarity. Fig. 5 shows a diagrammatic representation of the brake control apparatus when a control signal 27 from the gating logic circuitry is adapted to control a solenoid driver circuit 49 to operate a solenoid-operated valve 51. The valve 51 is arranged to reduce the pressure within a vacuum cylinder 52 by connecting the cylinder to a vacuum reservoir 53 when the solenoid is actuated that is when the control signal 27 is positive. The pressure in the vacuum cylinder 52 is thereby reduced to cause movement of the piston 54 downwardly to provide a counter force through suitable linkages to the braking force being applied by the operator to the vehicle wheel brake. When the control signal 27 is at zero, the vacuum cylinder 52 is open to atmosphere through the line 55 so that no counter force is applied to the braking force produced by the vehicle operator and full braking force is maintained at the wheel to be braked. The logic circuit includes five solid state gating elements 44-48 inclusive shown and arranged in the manner disclosed in Fig. 4A.

Abstract: 1289796 Producing ampicillin TOYO JOZO KK 19 April 1971 [27 Feb 1970 24 Sept 1970] 23549/71 Heading C2A Ampicillin is produced by esterifying penicillin G to protect the 4-carboxyl group, reacting the ester with a chlorinating agent in the presence of a tertiary base to give an imide-chloride-groupcontaining compound of Formula III: wherein A is the esterifying group, reacting this compound with a metal carboxylate of Formula IV: where M is a metal atom and B is a protected amino group, to give a diacylpenicillin ester of Formula V: and subjecting this compound to dephenylacylation, de-esterification and elimination of the amino -protective group. Suitable esterifying groups are benzyl, pnitrobenzyl, phenacyl or p-bromophenacyl groups. The ester is reacted with PCl 5  in the presence of pyridine to give the compound III. The α-amino group of the metal carboxylate IV is protected by, e.g., carbobenzoxy, p-nitrocarbobenzoxy, carboaryloxy, p - toluenesulphonyl, trityl, benzyl, dibenzyl, benzylsulphonyl, o - nitrophenylsulphonyl, trifluoroacetyl, chloroacetyl, formyl or o-nitrophenoxyacetyl. The protective group is removed in the final stage of the process by, e.g., reaction with trifluoracetic or dichloracetic acid or by catalytic reduction. The dephenylacetylation of the compound V is effected by aminolysis or by reaction with a metal thiophenolate or halothiophenolate. Aminolysing agents may be primary or secondary organic amines, ammonia or an N,N-disubstituted aminoalkylamine. The use of a metal thiophenolate or halothiophenolate can bring about simultaneous de-esterification in which case it is used in excess of the compound V, e.g. 2-4 moles per mole of compound V. If used in about equimolar proportions, however, only the dephenylacetylation step is effected. Suitable reagents are sodium or potassium thio- or p-chlorothio-phenolate. If necessary, de-esterification is then carried out, e.g. by catalytic reduction or reaction with a metal thiophenolate or halothiophenolate, to give the desired ampicillin.
