A sorting device comprises four plastics strips (15-18) each suspended from the free end of a horizontal pivotable arm 8-11 movable between a normal position and one other position, to direct mail into appropriate channels. The arms are moved by rotary magnets 23-26 connected thereto by levers 27-30 having rollers 31-34 on their free ends in spring contact with intermediate members 35-38 attached to the arms 8-11, which are spring-returned to their normal position. The mail is moved in a direction parallel to the pivotal axis of the arms by two pairs of roller conveyers (1-4) co-operating with a feeder hopper (5, 6) and a further two pairs (19-22) below the arms. There are five separate conveying channels formed between the arms and a fixed guide wall (not shown). The movement of the arms is limited by stops 13, 14 and the arms are strengthened by having an inverted U cross-section and a stiffening bend in their longitudinal axes.

Title: Cylinder lock arrangement with alarm device
IPC: E05B45/14
Filed: 1975-12-11
Abstract: 1502389 Alarm-equipped locks W WINKHAUS and H WINKHAUS [trading as AUG WINKHAUS] 11 Dec 1975 [11 Dec 1974] 50850/75 Heading E2A A locking mechanism comprising a cylinder lock and a rim lock, the bolt of which is moved by means connected to the cylinder lock, is equipped with an alarm which is actuated by an electric circuit which is completed when attempts are made to open the door by means other than the use of the proper key. In Fig. 9, device 148 carrying a contact 154 is mounted by a pivot 150 on the cylinder lock casing 126. One end of an alarm circuit is connected to the contact 154 through terminals 156 and the other is connected to the casing 126. The device is attached to the door, or to a sleeve mounted in the door, through a spring which may be a leaf spring 178 or a bent wire (58 in Fig. 5). Attempts to prise the cylinder out of the door cause the device to tilt about pivot 50, 150 so that the circuit is completed by contact 154 engaging pin 168 set in the casing. The lock may be permitted to yield a short distance by mounting it by screw 120 through back plate 190 to a pressure plate 196 separated from plate 190 by springs. This allows sufficient movement to trigger the alarm but insufficient to damage the lock. Use of a skeleton key, a pick lock or an incorrect key will cause the pin tumbler 38aa to rise and push pin 60, sliding in slot 62 cut in the casing, into contact with contact 54 (see Fig. 5). Warning of attempts to force the door is given through another circuit, one end of which is connected to the casing 224 of rim lock 214 standing proud of the door 212, the other end being connected to contact plate 248. Pressure on the locked door 212 causes bolt 218 to press hard on its keeper 220 and so force the rim-lock 214, against the action of springs 236, against the contact plate 248 (see Fig. 12).

Title: Improvements in or relating to pyrrolidonyl-ª-butyramide and the hydrolysis products thereof
IPC: G03C5/305
Filed: 1964-12-16
Abstract: Complexes of pyrrohdonyl-a -butyramide, having the formula <FORM:1085910/C6-C7/1> with halide salts of Cu, Au, Ag, Te or Pt can be used in the plating of copper, bronze, brass or stainless steel. A silver plating solution may be prepared by reacting a silver halide with an equivalent of the amide, adding one equivalent of hydrobromic or hydroidic acid and diluting the solution with a liquid organic amine.ALSO:The invention comprises pyrrolidonyl-g -butyramide, pyrrolidonyl-g -butyric acid and g ,1g -amino-dibutyric acid having the formulae <FORM:1085910/C2/1> <FORM:1085910/C2/2> and <FORM:1085910/C2/3> and the salts thereof.  Pyrrolidonyl-g -butyramide is obtained as a co-product in the process for making 2-pyrrolidone comprising heating a mixture of g -butyrolactone and anhydrous ammonia in the molar ratio 1: 1.1 to 1: 1.5 maintained at 140-220 DEG  C. under a pressure of 1600-2300 lb./sq. inch (gauge) to yield a mixture containing g  - hydroxy - butyramide, heating said mixture to 250-300 DEG  C. whereby 2-pyrrolidone is formed, passing the mixture to a flash drum maintained at 200-275 DEG  C. and 40-300 mm. Hg (gauge) whereby 2-pyrrolidone forms the overhead product and a residue settles in the bottom, characterized by preheating said mixture of g -butyrolactone and ammonia to 50-100 DEG  C. under a pressure of 15-600 lb./sq. inch (gauge) for at least 2 1/2 hours before heating as above to 140-220 DEG  C., whereby the residue in the flash drum is a greenish-brown oil containing pyrrolidonyl-g -butyramide, which oil is treated with a non-solvent for pyrrolidonyl-g -butyramide to leave a residue of crude pyrrolidonyl-g -butyramide which can be purified by recrystallization.  The amide can also be made by (1) oxidizing the product obtained by reacting g -butyrolactone and n-butanolamine, to give the corresponding acid which is converted to the amide using ammonia, (2) reacting N-hydroxypropyl-2-pyrrolidone with PCl3 to give N - (3 - chloropropyl) - 2 - pyrrolidone followed by treatment with KCN, hydrolysis to the acid and conversion to the amine and (3) reacting 2 - pyrrolidone with g  - chlorobutyramide. The amide forms metallic salts, e.g. Na, Ag, Mg, Hg and Zn salts. Pyrrolidonyl-g -butyric acid is made by hydrolysis of the amide with one equivalent of a mineral acid or an alkali metal hydroxide.  By employing 2 or more equivalents of acid or alkali, the hydrolysis proceeds to give g ,g 1-aminodibutyric acid. The latter compound undergoes ring closure at its melting point to yield pyrrolidonyl-g -butyric acid.  g ,g 1-Amino dibutyric acid is converted to the di-acid chloride on treatment with PCl3 and yields esters with alcohols, e.g. methanol. Pyrrolidonyl-g -butyric acid is converted to the methyl ester by treatment with diazomethane. The amide and its complexes with halide salts of Cu, Au, Ag, Te and Pt are used as antistatic agents in photographic films or for plating metals respectively (see Divisions C7 and G2).

Title: Seal of polytetrafluoroethylene
IPC: B29C43/00
Filed: 1977-12-15
Abstract: In the production of multi-layer PTFE seals to be held in a valve closing element or a valve seat, pure PTFE powder is compacted in a first compacting operation for a first, thin covering layer (34) forming the sealing surface of the seal. A mixture (33) of PTFE powder and a filler which can be washed out is then compacted by a second compacting operation to form a region, which is rubber-elastic due to its porous nature, of a second layer situated at the bottom during use. The whole is then sintered. After the sintering process, the filler is washed out. The thickness of the bottom layer in the compacted state is about four times the particle size of the filler, which is about 0.25 to 0.5 mm, while the covering layer is at least 0.3 mm thick. The PTFE powder to be mixed with a filler which can be washed out can be electrostatically discharged prior to mixing. <IMAGE>
