Title: Polyamide injection mouldings prodn. - with the activator catalyst system being charged separately from the lactam
Inventor: BRASSAT BERT DR
IPC: C08G69/16
Filed: 1976-04-29
Abstract: Polyamide mouldings are produced by polymerisation of lactams using an activator-catalyst (A-C) system in injection moulding machines. The lactam without the A-C system or with is not >one of its components, is fed without pressure into the moulding machine cylinder, moved forward and heated. When a temp. the melt temp. of the polyamide is reached the lactam is polymerised by adding the A-C system, or the missing component, and is finally injected into a mould where the polyamide sets. The new procedure enables activated anionic lactam polymerisation to be carried out in normal injection machines without e.g. pressure charging or pre-polymerisation equipment. Local overheating of the compsn. and screw obstruction does not occur. Prods. uniformly polymerised and with good mechanical properties are obtd.

Title: Heat treatment of granular fruit seeds - with precise control of heating rate, temperature and duration (OE 15.9.78)
Inventor: ZVONICEK JAN PROF DR
IPC: A23L11/30
Filed: 1977-04-27
Abstract: Fruit contg. granular seeds is fed via a hopper and regulating feeder into an oven. The fruit passes through the oven on a belt or vibratory transporter and is heated by means of ultra-high frequency electromagnetic waves or infra-red radiation to the desired temp. It then passes through a second chamber in which the temp. is maintained. This chamber is insulated and equipped with sec. heating which may be similar to the heating system in the first chamber, or, as pref. resistance heaters. The treated fruit then passes through a crushing or rolling device into a cooler and thence to storage or subsequent treatment. The best treatment for each type of fruit is predetermined experimentally and then the temp. to which the fruit is heated in the first section is adjusted by varying the intensity of the radiation or by switching it on and off, and the duration of each stage is varied by adjusting the feed rate and length of travel through each section. The system enables the rate of heating, duration of treatment and temp. to be precisely regulated according to the nature of the fruit being treated. The result of this is an improved final content of digestible protein and energy.

Patent DE-2719207-A1 (DE)
Inventor: YAMAZAKI HIROSHI
IPC: G04C21/36
Filed: 1977-04-29
Abstract: In apparatus for generating an alarm sound especially for small watches, all functions of the alarm are controlled by integrated circuitry which detects the state of a common connection point between a manually operable switch and a reference switch which is opened and closed by the timekeeping mechanism. There is thus only one external terminal led out from the integrated circuit for the purpose of connecting to the output side of the reference switch and the manually operable switch. The reduction in the number of terminals permits a corresponding reduction in the number of pins required and a reduction in the size of the circuit. The integrated control circuit includes flip-flops, gate circuits, inverters and a five minute counter.
