Abstract: ABSTRACT OF THE DISCLOSURE A back-up guide for trucks or trailers is made of two elongated members attached perpendicularly to each other, with spikes on their underside to hold the device in a stationary position. The longer of the two members provides a guide for the side of a vehicle's rear wheel during backing up, and the other, shorter, member is laterally disposed and provides a wheel chock or stop member for the rear wheel, and also acts as a visual stop point for the driver. The lateral member has a rearward extension near each of its ends, which provides supports for wheels which allow easy movement of the device when the front end is raised to lift the spikes clear of the ground. Both members may be equipped with handles for ease of handling. The device may be transported by attachment to the side and back of a truck or trailer, resting on special brackets attached to the truck or trailer.

Abstract: ABSTRACT OF THE DISCLOSURE         A receiving circuit for receiving an FM-modulated television signal with an energy dispersal signal superposed thereon is used for a television receiver for receiving the FM-modulated television signal.  The receiving circuit is provided with a triangle wave signal generator for generating a triangle wave signal in synchronism with a vertical synchronizing signal.  The energy dispersal signal superposed on the FM-modulated television signal is suppressed by frequency modulating an oscillation signal of a local oscillator by the triangle wave signal obtained.

Abstract: Abstract of the Disclosure Electronic printer apparatus in which the inten-sity of the beam of a cathode-ray tube is controlled dur-ing successive beam sweeps to display and project onto a rotating electrostatically-charged surface an image of successive slices through a row of characters to be printed, the latent line images thus formed being then converted to a toner image for subsequent transfer to a page of paper.  Digital information bits organized in bytes and representing slices through each character are stored in respective areas of a permanent memory storage device.  The appropriate slices of the characters are accessed in response to character-representing input sig-nals, and are read out serially to control the beam in-tensity during each sweep and thus display, along the sweep, the desired slice through the row of characters. The stored bits for each character slice are organized into various integral numbers of x-bit and y-bit bytes, preferably 8-bit and 6-bit bytes, the number of bytes of each type for each character slice depending on the bit width of the corresponding character cell; there are no extra or left-over bits beyond these included in the two types of bytes.  The so-stored bytes of differing bit content are accessed byte-by-byte, enabling simpli-fication and reduced cost of the apparatus.

Abstract: Abstract The piston rod of at least one hydraulic cylinder is axially connected to a pivot pin about which the car holding arm of a car holding device rotates in a vertical plane to engage the couplings between railroad cars.  In the case of a single hydraulic cylinder, the inner chamber of the cylinder, located closest  to  the  car holding  arm,  is  connected  to  the  outer chamber on the  other side of  the piston by a conduit.  When hydraulic cylinders are connected to each pivot pin of the car holding  arm,  the  inner  chambers  of  the  two  cylinders  are interconnected by a conduit as are the two outer chambers. When flow  through  the  conduits  is  blocked  by  a  solenoid  valve, movement of the car holding arm in the direction parallel to the track is resisted and the arm holds the train in position. When the solenoid valve is open, the load imposed by the train on the car holding arm causes the hydraulic fluid to flow between the interconnected chambers and the arm moves parallel to the track until the load is relieved so that the arm can be raised out of engagement with the train under no-load conditions. A pump can be selectively connected to the conduit to transfer hydraulic fluid between chambers to recenter the raised arm or to position it precisely prior to reengagement with the train.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for forming miniaturized optical components such as fiber optics connector terminals in which a three-part mold set is employed to attain precise concentricity of mold cavity formations carried by two of the three mold parts which are movable axially relative to and positioned by the third or central one of the three parts.  The two movable parts are each located by oppositely diverging frustoconical reference surfaces on the central part and include mold surface components which are axially positionable relative to the parts in which they are carried.  The central part is supported by a shuttle for movement between a molding position and an ejection position, appropriate ejection pins being located in spaced relation to the molding position so as not to interfere with the molding operation.  Precise concentricity and axial location of the three mold parts is effected in substantial measure by application of a mold closing force exclusively along the common axis of the three parts and under a force limited to a pre-established value.

Abstract: Abstract Sample Inlet System for an Electron Capture Detector An electron capture detector for use with a capillary column is provided with a sample inlet comprising a tubular anode through which sample molecules and a make-up gas are introduced into the detector cell.  The tubular anode has side ports for producing a plug-like flow inside the cell.  The inner surface of the anode is protected by an insulating tube so that the capillary column can be extended to a point beyond the side ports without the fear of its electrical contact with the anode. This allows the sample molecules to flow nearly entirely in the center section of the cell.  The peripheral regions of the cell where a radioactive foil is disposed is swept nearly entirely by the make-up gas entering the cell through the side ports. This has the effects of reducing sample dilution by the make-up gas and sample loss due to contact with the detector walls.

Abstract: ABSTRACT OF THE DISCLOSURE:          The present invention deals with a method for producing 2-phenylethylchlorosilanes.  The starting pro-ducts used are hydrogenchlorosilanes and styrene which are reacted with each other within the framework of the addition-reaction known per se.  According to the invention, this reaction takes place in the presence of benzothiazole. The amount of benzothiazole used may correspond at least to the amount of platinum catalyst used.  The preferred molar ratio of platinum catalyst to benzothiazole used is between 1 : 2 and 1 : 50.  The reaction may be carried out with high yields of the 2-isomer, which is practically free from 1-isomer, at temperatures of up to about 90°C.  In this connection, an overpressure of up to 6 bars can easily be tolerated without any appreciable drop in yields of the desired end-product.
