Abstract: --ABSTRACT OF THE DISCLOSURE      A safety interlock system for microwave ovens com-prising first and second interconnected switches activated by the oven door. Each switch has make-and-break contacts.          The first switch interrupts the current to the microwave source when the door is opened and the second switch moni-tors the operation of the first switch. The switches are connected in series with a fuse so that a malfunction of either of the switches makes the oven immediately unusable.          A delay element is connected within one switch and the first switch is arranged to operate before the second switch when the door is initially opened.--

Abstract: ABSTRACT OF THE DISCLOSURE A method of forming an underwater structure includes fabricating an impervious membrane to form a substantially totally enclosed container. The membrane is transported in a collapsed condition to the site and ex-tended to cause a base portion thereof to rest on the river or sea bed. The membrane is filled with a body of non-settable material which is then drained with pumps to enable the external water pressure to exert a confining pressure on the body to render it coherent.  One form of structure has an upper deck section, a lower gravity section resting on the sea bed, and an impervious membrane secured in water-tight fashion to the lower peripheries of the deck and gravity sections.  The particulate material is filled into the space between the sections and the membrane.

Abstract: ABSTRACT OF THE DISCLOSURE        A channel monitoring system for monitoring the bit error in a transmission channel transmitting PCM signals is disclosed. The system is a parity check system in which only one parity bit for one monitoring section of the PCM signal is necessary even for a transmission system employing dif-ferential modulation. The transmitter side of the system includes a series parallel converter, multiplexer and parity counter and the receiver side in-cludes a parallel series converter, demultiplexer and counter. In the system binary codes are converted in to differential binary codes. The binary codes are continuously parity-counted for the number of codes corresponding to a particular time slot but the subsequent binary codes are not parity-counted for the same number of codes corresponding to the time slot. One bit of the parity signal corresponding to the parity-counted codes is generated.

Abstract: ABSTRACT OF THE DISCLOSURE        The inventions relates to optical inspection apparatus for monitoring a continuously moving rod, the apparatus comprising a circular head through which the rod passes, a first set of fibre optic conductors which transmits light from a source to the head to illuminate the rod, and a second set of fibre optic conductors which pick up light reflected from the rod passing through the head and transmits the reflected light to a number of photoelectric elements. The second set of conductors are divided into angularly spaced groups around the head and adjacent groups lead to separate photoelectric elements. The outputs of the elements are fed via A.C. coupling means into separate channels connected to comparator means responsive to the noise signal level in the individual channels. The comparator means produces a fault pulse in the signal level in any one channel is greater than a preset allowable level. Each of the channels includes an amplifier for amplifying the noise signal, the level of the noise signal being fed back to control the amplifier gain so that the mean level of the amplified noise signal is maintained substantially constant.

Abstract: ABSTRACT OF THE DISCLOSURE In a cylindrical casing, a temperature regulation system shifts a valve sleeve body axially between valve seats of the cold and hot water inlets and a flow control lever mounted on screw threads propels a valve seat body mounted as a piston within the casing and carrying one of the valve seats so as to vary the distance between the two valve seats between which the sleevelike valve body moves.  The control rod of the temperature regulating system passes through the valve seat body to hear against a balance spring the other end of which is adjustable by a temperature setting grip that varies the compressive force on the spring, but an adjusting device is interposed between the control rod and the spring for slightly varying the effective rod length in accordance with the position of the flow-control lever so as to compensate for a tendency of the controlled temperature to shift from the preset value when the total flow is varied.
