Abstract: METHOD AND APPARATUS FOR            ELECTRICALLY INVESTIGATING A BOREHOLE                 Abstract of the Disclosure Methods and apparatuses for electrically investigating a borehole are described.  Tool mounted pads are provided, each with a plurality of small measure electrodes from which individually measurable survey currents are injected toward the wall of the borehole.  The measure electrodes are arranged in an array in which the measure electrodes are so placed at intervals along at least a circumferential direction (about the borehole axis) as to inject survey currents into the borehole wall segments which overlap with each other to a predetermined extent as the tool is moved along the borehole.  The measure electrodes are made small to enable a de-tailed electrical investigation over a circumferentially contiguous segment of the borehole so as to obtain indications of the strati-graphy of the formation near the borehole wall as well as fractures and their orientations.  In one technique, a spatially closed loop array of measure electrodes is provided around a central electrode with the array used to detect the spatial pattern of electrical energy injected by the central electrode.  In another embodiment, a linear array of measure electrodes is provided to inject a flow of current into the formation over a circumferentially effectively contiguous segment of the borehole.  Discrete portions of the flow of current are separably measurable so as to obtain a plurality of survey signals representative of the current density from the array and from which a detailed electrical picture of a circumferentially continuous segment of the borehole wall can be derived as the tool is moved along the borehole.  In another form of an array of meas-ure electrodes, they are arranged in a closed loop, such as a circle, to enable direct measurements of orientations of resistivity of anomalies.

Abstract: Abstract of the Disclosure Electro-optical apparatus, system and method for measuring distance to a relatively moving surface, such as distance to a road surface from a vehicle frame of reference passing thereover.  The apparatus includes a light transmitter for projecting a rec-tangular beam vertically downwardly onto the road surface.  A rotating scanner includes a circumferential array of facets for sequentially receiving the image diffusely reflected from the road surface and reflecting such image through a rectangular reticle onto a photo-detector.  Reference beams are sequentially reflected by the road image-reflecting scanner facets onto a reference detector.  Distance to the road surface is then determined as a function of the angle of incidence of the road image onto the scanner by comparing the time of incidence of the road image to the times of occurrence of the reference reflections on the reference detector.

Abstract: ABSTRACT: "System for communication by way of repeatedly trans-mitted messages, and stations for use in such a system"           A description is given of a system for communication between a transmitting station (30) and a receiving station (33) by way of a message which consists of a direct succession of a number of identical code words. Each message uses only a comparatively small part of the capacity of the message channel. Each code word has at least a predetermined minimum Hamming distance with respect to any other code word, including the cyclic transpositions of the latter code word. Therefore, for the detection and reproduction of a code word it is not necessary to realize word synchronization and a given category of errors can still be detected and/or corrected. The code words may concern, for example, a transmitter or program identification in a broadcasting system or a paging code for a receiving station in a system comprising selectively addressable receiving stations (paging system).

Abstract: HYPODERMIC SYRINGE CARTRIDGE WITH NON-RETRACTABLE DRIVE PISTON                ABSTRACT OF THE DISCLOSURE         The drive piston of a hypodermic syringe is rendered non-retractable by including on it a resilient disc-like element whose free diameter is slightly larger than the diameter of the glass tubular body of the syringe.  The drive piston is inserted into the glass tubular body from the rear end, thereby causing the resilient disc-like element to become dished with its, concave side facing rearward.  The dished resilient element acts as a continuous pawl since any attempt to retract the drive piston jams the edge of the resilient element against the inside wall of the tubular body.

Abstract: In regulating the flow of cooling water sprayed upon a metallurgical product such as a steel slab in a machine for the continuous casting of such products which then undergo a straightening operation, the present, past and future speeds of the product are taken into account so as to compensate a projected change in the temperature of the product in the straightening stage, due to a planned or expected modification of the cooling conditions. These conditions are established by a regulating system responsive to changes in the speed of the product; the anticipated temperature change is compensated by substituting for the true speed, as a controlling parameter, a fictitious speed lying between the true speed and an advance image of an anticipated speed change whose effects upon the temperature are to be neutralized.

Abstract: Abstract The invention relates to a welding system for Tig welding.  To initiate welding, a tungsten electrode is brought momentarily into contact with the object to be welded and then separated from the object to initiate an arc.  A low short-circuit current is led through the welding circuit during this contact.  The interruption of the low short-circuit current is used to control the welding power source to increase the current in the welding circuit to a value above a preset welding current value intended for the welding process proper.  After a short period of time, the current is decreased to the preset value.  This system permits welding to be carried out safely and easily and without electrode "drag" marks being formed on the article to be welded.

Abstract: ABSTRACT OF THE DISCLOSURE         A vertically storable trailer embodying a flat, triangular frame has mounted thereon a container bottom for receiving a load and a container top that is sealingly and lockably engageable with the bottom for securely enclosing the load.  The top and bottom have outwardly sloping forward and side walls to permit nestably storing the top in an inverted position within the bottom to reduce trailer storage space and a rearwardly facing flat end wall of the bottom is normal to the frame to facilitate tilting the trailer thereon to reduce floor storage area requirements.  Wheel suspension assemblies include a pair of tubes, one end of each tube being pendulously attached to the frame adjacent either side of the container bottom.  A wheel is rotatably journalled to an axle affixed to each tube adjacent its free end and within the free end is mounted a shock-absorbing resilient load sustaining unit.         A suspension support is pivotally attached to the frame on either side of the container bottom in releasably engageable relation with a bearing of each load sustaining unit for locking same in an operable position to provide ground engagement of the wheel with a predetermined road clearance and releasing the locked load sustaining unit automatically by means of a ground contacting pushrod when the trailer is tilted onto the end wall.  When released, the suspension assemblies swing inwardly of the frame to minimize trailer storage space.
