Abstract: HYDRAULIC FUNCTION DISCONNECT MEANS                    Abstract of the Disclosure A hydraulic function disconnect means is interposed between an operator's control lever and a spring centered hydraulic control valve for a hydraulic motor actuator.          The means is operable when the hydraulically actuated element approaches a limit position to prevent any operation of the valve by the lever which would move the element toward the limit position while permitting operation of the valve which results in movement of the element away from the limit position.  A solenoid operated detent is used to control the ability of the disconnect means to transmit movements of the lever to the valve.  The hydraulic function disconnect means forms part of the linkage in a two blocking prevention device used on boom-type material handling equipment such as a cable equipped crane in which the hydraulically actuated element comprises the movable hook and the cable is drawn in or paid out by a hydraulic motor actuator.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to a cigarette making machine of the kind having a fixed member and a movable packing block together defining a cylindrical cavity for compressed tobacco, a nozzle communicating with the end of the cavity for supporting a preformed paper tube and an ejector for ejecting the charge of compressed tobacco through the nozzle into the paper tube. A new operating mechanism for such a machine comprises a sliding member including a rack and D pivoted lever secured to the compression member having gear teeth in meshing engagement with the rack and operatively connected to the ejector. Restraining means restrains rotation of the lever during a first portion of the travel of the sliding member during which the tobacco is being compressed, after which said means disengages from the lever to permit rotation thereof in a second portion of the travel of the sliding member in which said ejector forces the charge of compressed tobacco through the nozzle into the paper tube. The mechanism is simple and compact and it enables both the compression and the ejection operations to be carried out smoothly using a single operating handle.

Abstract: ABSTRACT:         An optical read apparatus for a disc-shaped record carrier. The read apparatus comprises an optical read unit which includes a deflection element for control-ling the radial position of the scanning spot, for which purpose said deflection element is included in a closed servo control loop. In order to enable a desired pro-gramme section on the record carrier to be located rapidly, the read unit can be moved in the radial direction. Dur-ing this movement of the read unit the servo control loop is rendered inoperative each time after the deflection element has reached a preset maximum deflection, after which this deflection element is reset rapidly and the servo control loop is rendered operative again. Thus it is achieved that image reproduction is also maintained dur-ing the rapid search for a desired programme section.

Abstract: RECURSIVE-LIKE ADAPTIVE ECHO CANCELLER            Abstract of the Disclosure The present invention relates to an echo cancellation apparatus.  The apparatus is comprised of an adjustable signal processing network connected to form a signal path shunting the leakage signal path of an echo return signal on one side of a junction connecting transmission circuits.  The network synthesizes, from the transmission signal that produces the echo return signal, a replica to approximate the echo return signal.  A signal combiner is connected to receive the replica and another signal for providing a residual echo signal for adjusting the network.  A second adjustable signal processing network is provided which is responsive to the residual echo signal and is connected to receive the return echo signal to provide a selective signal modification or the other signal of the signal combiner.  The networks are adjustable together to adapt to a model of the transfer function of the leakage path which is characterized by a rational mathematic expression possessing poles and zeros as respective roots of the denominator and numerator of the rational expression whereby the effect of transmission zeros inherent to the leakage path is substantially eliminated by the first mentioned network and the effect of transmission poles inherent to the leakage path is substantially eliminated by the second mentioned network when the residual echo is at a minimum magnitude.

Abstract: METHOD FOR HEAT TREATMENT OF CLAY                   AND REFRACTORY WARE ABSTRACT      In the manufacture of clay or refractory ware containing oxidisable material, stacks of the ware are passed through a tunnel kiln and a flow of air passed over the stacks.  Fuel burners are operated to provide the necessary stages for firing the ware,  These stages include an oxidation stage in which residual oxidisable material is oxidised.  Gas containing more oxygen than air (i.e. commercially pure oxygen or oxygen-enriched air) is introduced into the region of the kiln where the oxidation takes place.  The oxygen-rich gas is caused to penetrate at least one stack for the time being in the oxidation region so as to increase the concentration of oxygen throughout the individual items of ware within said stack.  It is thus possible to oxidise all the residual oxidisable material.  At least 50% of such oxidation is typically confined to a temperature range of 100°c.  The heat thereby released assists in the firing of the ware.
