Patent GB-2089716-A (GB)
Title: A moulding machine having power cut-off means
IPC: B29C45/00
Filed: 1981-10-14
Abstract: Power cut-off apparatus is provided for use with a moulding machine of a type wherein a clearance G is normally reduced following closure of mould parts (2, 14) respectively attached to fixed and mobile sections (4, 3) of the machine. Respective detecting means (11, 12) in the form of contacts are provided to detect contact between the mould parts and a subsequent reduction of the clearance. When foreign material is present between the mould parts (14, 2), the detecting means (12) which responds to a reduction in the clearance (G) is actuated i.e. closed by an actuator 13 whereas the detecting means (11) which responds to contact between the mould parts remains closed. When this occurs, a relay winding 14a is excited by a power source 15 through the closed contacts 11, 12 so that normally closed contacts 14b of the relay 14 are opened, thereby switching off the power drive 17 of the moulding machine 16 thus stopping movement of the mould parts (14, 2) towards each other. Also a normally open contact 14c of relay 14 is closed, thus actuating an alarm device 19.   A modified arrangement of the cut-off apparatus and moulding machine is shown in Figure 5 (not shown). <IMAGE>

Title: Analog-to-current converter for sampled systems
Inventor: HERZL PETER J
IPC: G11C27/02
Filed: 1981-10-28
Abstract: A sample and hold circuit converts an analog voltage into an output current of related intensity and to hold this current beyond the sampled interval. The converter includes an operational transconductance amplifier (16) having inverting and non-inverting inputs and a bias terminal, the amplifier being rendered operative for the sampling interval by a positive voltage applied to this terminal. The analog voltage is applied to one of the inputs to produce a voltage in the amplifier output which acts to drive a transistor (18) connected in series with a resistor (21) in a current-producing network, causing current to flow through the resistor to develop a feedback voltage which is applied to the other input of the amplifier, which current assumes an intensity related to the analog voltage. An R-C holding network (23, 24) connected to the amplifier output acts to maintain the drive voltage developed during the sampling interval beyond this interval, thereby holding the resultant output current. <IMAGE>
Patent GB-2090933-A (GB)
Title: Anchoring of screw sockets in bores
IPC: F16B12/44
Filed: 1981-11-17
Abstract: When a screw socket 10 is inserted into the bore 22 by pressing together the smooth resilient arms 15, the arcuate radial projections 18 on the arms 15 slide along the surface of the bore without scraping dust from the bore wall so that there is no likelihood of drilling dust preventing correct positioning of the dowel 10. Upon reaching bore widening 24, arms 15 return to their initial position as projections 18 snap in positive manner into said widening 24. Protrusions 17 prevent twisting of the screw socket 10 in the bore 22 when fastening screws are inserted or when the dowel is subjected to a load. <IMAGE>
