Title: Cutting shapes from plastic material webs - using rotating hollow cutter of required section which ejects by central air pulses
Inventor: HERMANN HANS-JOACHIM
IPC: B26F1/38
Filed: 1977-05-06
Abstract: Shapes are cut out from moving webs of elastic or plastic materials (partic. rubber or polymers) by using a rotating radial cutter and counter pressure roller which lightly touches the cutter, rotates at the same speed, and is wrapped round by the web of material. The cutter is prismatic and hollow, is mounted on a rotating shaft, and its end cutting edge is at the circumference of a circle whose radius is the distance between its shaft and the roller; the machine also has a device to eject the cut shapes produced. The method is wholly mechanised, provides constant accuracy and a controlled sequence feed to subsequent operations.

Title: Ammonia and sulphuric acid mfr. from waste ammonium sulphate soln. - by electrodialysis process needing only low amt. of electric power
Inventor: BEHRET HEINZ DIPL CHEM DR
IPC: C01C1/02
Filed: 1977-06-18
Abstract: The soln. is subjected to electrodialysis in a cell divided into three chambers by an anion - and a cation - exchange membrane. A hydrophobic cathode depolarised by O2 in air is used. H2SO4 is fed through the anode chamber; and an alkali is fed through the cathod chamber. The process pref. operates at 40-80 degrees C. using alkali with concn. 0.1-5% and with continuous winning of NH3 in a catholyte circuit used between the outlet of the cathode chamber and a storage chamber which contains a stripper column through which air is drawn by suction, the column being followed by a holding tank. The cathode pref. has a catalyst of active carbon, pyrolysed organic cpds., or N4 - transition metal chelates, esp. iron- or cobalt- phthalocyanine. (NH4)2SO4 solns. are often obtd. as by-prods. e.g. in mfg. caprolactam used in making polyamides. Valuable prods. are produced from the solns. which would otherwise cause environmental pollution as the demand for (NH4)2SO4 is limited. The method has low energy consumption.

Title: Mandrel for drawing seamless tubes - has collar of silicon nitride for long service life and good surface finish
Inventor: KESSEL HEINZ ING GRAD
IPC: B21C3/16
Filed: 1977-07-09
Abstract: The drawing of seamless tubes is facilitated by using a mandrel with a collar made from hot pressed silicon nitride. The bore of the collar has a slight taper of 3-6 degrees which matches the taper of the mandrel. When the collar is first fitted on the mandrel there is a small end clearance between collar and shoulder. This clearance is taken up by screwing up the nut so that a controlled hoop stress is created in the collar. This reduces the risk of the collar bursting during operation. This type of mandrel with a silicon nitride collar has a long service life and produces tubes with a very high standard of internal surface finish.

Title: Miniaturised pin-socket type - has cylindrical pin with enlarged and ogival shaped end receivable in squared section hole socket
Inventor: BERNIER RAYMOND
IPC: H01R13/11
Filed: 1978-02-01
Abstract: The pin includes a cylindrical part(3) which ends in a part (4) which is slightly enlarged and ogival in shape.

Title: Data transmission clock pulse recovery appts. - has receive terminal with delayed signal and off=line signal comparison and setting counter giving recovered pulse at output
Inventor: MELCHIOR FRIEDRICH DIPL PHYS
IPC: H04L25/49
Filed: 1978-12-23
Abstract: Circuitry is for recovery of clock pulses from an incoming data transmission so that the clock pulses can be used for synchronising a decoder, esp. applicable to Bi-phase coded transmissions. A passive delay line delays the incoming signal whilst a by-pass path directs an undelayed signal directly to the input of an exclusive OR gate, the delayed input is presented to the other gate input. The gate output operates the set input of a counter and the recovered clock pulse is taken from the output. The delay line comprises two NAND gates (1, 4) and RC circuitry (2, 3, 5, 6). The delayed and undelayed signals are input to an Exclusive OR gate (7) with its output fed to a NAND gate (8) with a feedback from the counter (9). The NAND gate (8) output is used to set the counter (9). The D type Flip Flop (12) delays the incoming data (E) so that it is available at the output (A2) with reconstituted clock pulse and in sync with the clock pulse at the other output (A1).
