Abstract: ABSTRACT OF THE DISCLOSURE                REMOTE SENSOR TELEMETERING SYSTEM          A telemetering system for remotely measuring a physical parameter of an object such as a human or animal includes a sensor device affixed to the object including a tuned circuit and a parameter sensitive device coupled for altering the figure of merit of energy storage (Q) of the tuned circuit in response to variations in the physical parameter, and an indicator unit for transmitting a signal to intermittently ring or energize the tuned circuit with a burst of oscillating electromagnetic energy and sense the resultant reradiated ring signal generated by the tuned circuit.  The indicator unit measures the rate of decay of the sensed reradiated ring signal after the end of each transmitted energy burst as a measure of the Q of the tuned circuit.  The indicator unit includes a micro-processor which generates a measure of the rate of decay and then computes the measure of the physical parameter according to a prestored functional relationship between the physical parameter measure and the decay rate of sensed ring signal. The computed measure is then displayed in a display device. A phase locked loop circuit in the indicator unit is coupled to alter the phase and hence the frequency of the trans-mitted signal to be in phase with the resonant frequency of the tuned circuit.  The decay rate may be measured by generating a ratio of peak voltage values sampled at two different but predefined times after the sensed ring signal begins decaying.

Abstract: ABSTRACT OF THE DISCLOSURE          A compact folding camera having a mirror in its exposure optical path includes a horizontal base section having a film plane therein, a pivoting lens housing near one end of the film plane, a pivoting mirror assembly adjacent the opposite end of the film plane, a foldable bellows, and a cover section.  The cover is pivotally coupled to one end of the base section near the mirror connection and is interconnected with the lens housing for coordinated movement by an erecting link.  The lens housing and mirror assembly are interconnected for coordinated movement by a linkage system.  When the camera is erected, the cover section is angularly displaced with respect to the base section so that the lens housing, mirror assembly and bellows may assume their upstanding erected positions over the base section in readiness to effect exposure of a film unit at the film plane.  In response to closing the cover section, the mirror assembly, bellows and lens housing fold down onto the base section wherein they assume a stacked relationship over the film plane and are protectively covered by the overlying cover section.

Abstract: ABSTRACT          SURFACE TREATMENT OF METAL RINGS         A metal ring of generally rectangular cross-section has its radially outer surface and its side surfaces treated by being stacked with its sides in contact with other rings in a chamber.  Air is excluded from the chamber and a gaseous mixture of a carburising gas and a nitrogenous gas at a temperature of 450°C to 650°C is supplied to the chamber.  The proportions (% by volume) of the gases is between 25:75 and 75:25.  The mixture nitro-carburises both the radially outer surface of the stacked rings and the sides of the ring.  If the rings are finish machined before treatment, they are ready for use as soon as they are removed from the chamber.  The nitro-carburising treatment reduces wear on the treated surfaces.  The rings are used as piston rings or sealing rings.

Abstract: ABSTRACT              CEMENTITIOUS BOARD MANUFACTURE         In the manufacture of cementitious board by depositing a slurry of hydraulic cementitious material, commonly gypsum plas-ter, between two facing sheets and forming it to the desired width and thickness prior to setting, the formation of voids in the core, due to air trapped in the slurry is avoided by vibrating the lower sheet (10) after the slurry (15) has been deposited on it, usually before the upper sheet (14) contacts the slurry, and subsequently vibrating the upper sheet when it comes into contact with the mass of cementitious slurry. The vibration of the lower sheet, for example by rotating polygonal shaft (20), causes bubbles of unwanted trapped air to rise through the slurry towards the upper surface and the accumulated bubbles are then broken by the vibration of the upper sheet, which may be accomplished by a second rotating shaft (21), before they become incorporated into the formed board as voids.

Abstract: MORTARLESS CONCRETE BLOCK SYSTEM HAVING REINFORCING BOND BEAM COURSES Abstract of the Disclosure In a mortarless interlocking concrete block system, general purpose intersection blocks 40 have parallel grooves 47 formed on their bottom surfaces 46, but each has mating ridges 45 on the upper surface 44 of its inner end 41 only.  The top surface 44 of its corner end portion 51 is flat, to permit an overlying course to fit thereon either at right angles or in linear alignment.  The corner end portion 51 has, in each of its two opposite side faces 54, 56 and in its outer end face 52, parallel vertical grooves 53, 55, 57 matable with tongues 17 of the system's stretcher blocks 10, to pro-vide interengagement at both left and right corners and T-shaped and crossing-wall intersections.  For bond beam courses, a bond beam intersection block 90 with similarly grooved 112, 114, 116 corner end 110 faces 111, 113, 115 has at its inner end portion 93 a closed-bottom channel 99 with saddle-like webs 101 extending between the chan-nel sides 92, to open through to its corner core 120 and support horizontal reinforcing rods b.  Consistently formed bond beam blocks 70 are provided, whose tongues 75 may engage any of the grooved 112, 114, 116 corner end 110 faces 111, 113, 115 at wall corners and intersections. Breakout provisions 121 in the corner core 120 inward of these faces 111, 113, 115 make it simple, at any inter-section, to lead horizontal reinforcing rods b to the cored corner 120 end portions 110, through which vertical rodding a and grouting is provided.  By utilizing hori-zontal reinforcing rods 133 formed at a right angle to extend through the corner block 90 between its two adja-cent blocks 70, the two perpendicular walls may be more securely tied together, to prevent vertical cracking. This furnishes to the easily-constructed mortarless wall block system a sturdy, reinforced concrete grid.          Where desired, blocks made of other material, for example, redwood may be utilized; also in miniature, the invention may be incorporated in sets of toy blocks, which have exceptional educational value.
