Abstract: A tubular premoulding of a thermoplastic, suitable for subsequent shaping to produce containers by a rolling process. The material in a part of a tube is axially oriented as a result of reducing the wall thickness by applying an external pressure which causes the material to flow. The oriented material is moulded by a blow-moulding process into future mouth parts and parts of adjacent neck sections, preferably from two blank parts, joined to one another, of pre-mouldings, the blank parts in the transition between the two mouth parts being severed in order to form two separate blank parts, so that, after closing one end and, if necessary, reworking in order to obtain the requisite closing faces at the other end, the two blank parts each form a tubular pre-moulding.

Abstract: The invention relates to an element of a thermoplastic of the polyester or polyamide type, and preferably of polyethylene terephthalate, the element consisting of an edge part which surrounds a body in an arrangement in which the latter is sunk relative to the edge part. The element is formed from a blank of mainly amorphous material or from a material having a crystallinity of less than 10%, the blank being, for example, a flat plate, a blank shell or the like. The body or parts thereof are shaped by stretching the blank until that material which is located within the material sections of the blank flows to from the edge part in the element, the material stretched to flowing in the body assuming a crystallinity of between 10 and 25%, while the crystallinity in the material in the edge part and in the unstretched parts retaining its original value of less than 10%. There is also disclosed a process and equipment for manufacturing the element.

The cam shaft relay is provided with a control member (5) having a first position which corresponds to the rest state of the instrument. Under the influence of the hook switch plunger (18) of the instrument, the control member (5) can be set to a second position corresponding to the lowspeaking state. The push button is provided with tipping element (2) which, when the button is depressed, actuates the control member (5) to set it to a third position corresponding to the loudspeaking state of the instrument.

Abstract: In a digital phase-locked loop, preferably for bit rate regeneration in synchronous data transmission systems, transmitting from a sender to a receiver redundantly coded information possibly modulated in a suitable mode there is an addition circuit connected to one control input of a digital controlled oscillator incorporated in the loop. The addition circuit adds control signal contributions from a phase comparator circuit of the loop and an error detector. This error detector is connected to an output of the receiver data detector, and examines whether the input signal in the circuit has the inherent redundant properties expected taking into account the signal coding. When this is not the case, a pulse-shaped control signal is fed to the addition circuit.

Abstract: Instructions which are read from a program memory of a control computer employing indirect addressing of a data memory are stored temporarily and sequentially in a buffer memory to form an execution queue. The absolute address to the data memory is generated by an address calculator by means of a base address derived from a reference memory in correspondence to an input address and by means of at least one address parameter which has been recorded in a register memory in connection with the execution of an instruction read from the buffer memory and transferred to a parameter register prior to the address calculation. In addition to each instruction, information is recorded in the buffer memory to indicate on the one hand whether the instruction is of the type which performs a write or read operation in the data memory and on the other hand whether it is of the type which enters address parameters in the register memory.
