Abstract: Abstract of the Disclosure An apparatus and system for unloading bulk particulate material from a railroad tank car is described.  At a discharge station a high pres-sure water distributor unit is provided with an outlet end adapted to be positioned over an inlet opening on each tank car.  A supply conduit is mounted for vertical rotation within each tank car with the conduit's upper end positioned within the inlet opening of the tank car.  A rotary conduit is carried on the outlet end of the distributor unit and is adapted to be coupled in fluid-tight, rotary connection with the upper end of the supply conduit.  A nozzle carried by the supply conduit is positioned for directing a high pressure stream of liquid to impinge upon and form a mixture with the material as the supply conduit is being rotated.  The mixture which is thus formed flows through a discharge opening of the tank car and into a collection receptacle provided at the discharge station.  A source of liquid under pressure supplies the distribution unit.  The discharge opening is in vertical register with the inlet opening.  The supply conduit extends from the inlet to the discharge opening.  A first bearing mechanism is mounted in the inlet opening for rotatably supporting the upper end of the supply conduit and a second bearing mechanism is mounted within the discharge opening for support-ing the lower end.

Abstract: ABSTRACT           A hitting device particularly adapted for use in the practice of martial arts, such as karate, which may be mounted on a vertical wall or post and carries a desired hitting surface.  The bellows portion contracts when contacted axially to absorb the impact of the hitting force. Closable vents are provided in association with the bellows portion to allow for variation of the compressibility of the bellows, thereby varying the resistance to the hitting force by the hitting device.  A force-indicating assembly is also mounted on the hitting device for approximately indicating to a student the hitting force applied.

Abstract: Abstract of the Disclosure The invention relates to a process for the prep-aration of 2-(2',2',2'-tribromoethyl)-4-chlorocyclo-butan-1-ones of the formula I                                           (I) in which one of the radicals R1 and R2 is methyl and the other is hydrogen or methyl, or R1 and R2 together are an alkylene group having 2 to 4 carbon atoms.  The process comprises reacting 2-chloro-4,4,4-tribromo-butyric acid chloride, in the presence of an organic base, with an ethylene, which is disubstituted in the 1-position by the radicals R1 and R2 according to the above definition, to give a 2-(2',2',2'-tribromoethyl)-2-chlorocyclobutan-1-one, and then rearranging this, in the presence of a catalyst, into a 2-(2',2',2'-tribromo-ethyl)-4-chlorocyclobutan-1-one of the formula I.  The 2-(2',2',2'-tribromoethyl)-4-chlorocyclobutan-1-ones of the formual I which can be prepared according to the invention are valuable intermediates for the preparation of 2-(2',2'-dibromovinyl)-cyclopropane-1-carboxylic acids and esters thereof having an insecticidal action.

Abstract: ABSTRACT OF THE DISCLOSURE           A paint spray booth which includes a system for supplying air thereto under controlled conditions, with a heat pump operated to produce cooling or heating adjustments to incoming air as required under summer or winter operating conditions.  Heat is transferred into or out of filtered air exhausted from the booth into the evaporator or out of the condenser by various heat exchanger arrangements to improve the operating efficiency of the heat pump during heating or cooling, respectively.  Dehumidification is achieved by cool-ing the incoming air to an appropriate dew point temperature and then reheating to achieve the proper supply temperature, which process is improved in efficiency by either an air-to-air heat exchanger which utilizes incoming air to reheat the air, or alternatively, by a pair of secondary air-to-liquid heat exchangers positioned on either side of the main heat exchanger to transfer heat from the incoming air to the dehu-midified air.  During heating, the secondary heat exchangers receive  heated liquid circulated therethrough in succession such that the first heat exchanger preheats the incoming air prior to passing through the main heat exchanger preventing freezing during water spraying of the main heat exchanger.          The second secondary heat exchanger supplies supplementary heat to the air after it has passed through the main heat exchanger.          A two-stage exhaust air heat exchanger arrangement is used to enable heat extraction below freezing.  A centralized system for conditioning the air supplied to a number of spray booths includes the use of hot and cold thermal accumulators through which are circulates the liquids from and to the various  ?t exchangers and the evaporator and condenser.

Abstract: ABSTRACT OF THE DISCLOSURE          A silicone emulsion having a dispersed phase of an anionically stabilized hydroxylated polydiorganosiloxane and a colloidal silica and a continuous phase of water in which the pH is 9 to 11.5 provides an elastomeric product, such as a film or coating, upon removal of the water at ambient conditions.  The silicone emulsion can be prepared by adding the colloidal silica to the hydroxylated polydiorganosiloxane in an emulsified state and thereafter adjusting the pH within the range of 9 to 11.5 inclusive with such materials as an organic amine or sodium hydroxide.  These emulsions are stable during storage over extended periods of time and will provide elastomeric products.  A silicone emulsion can also be prepared as described except the pH is adjusted above 11.5.

Abstract: ABSTRACT OF THE DISCLOSURE               A roller blind structure has an elongated tubular member which has end studs mounted for rotation and displacement in elongated openings in two spaced-apart brackets to be fixed to the sides of a window frame.  Coaxially secured to the tubular member is a pulley.  The roller blind screen is secured to the tubular member, and a cord for rotating the tubular member is secured to the hub of the pulley.  The cord is wound on the pulley in a direction opposite to the direction in which the screen is wound in the roller.  A tubular sleeve, having a downwardly-directed opening for the cord, has an axial projection sliding against an upper horizontal  surface of the bracket to prevent the sleeve from rotating but to allow it to be displaced with the pulley.  A guiding and locking device is provided at a vertical spacing below the sleeve and serves to guide the cord relative to the sleeve and to lock the cord in any desired position.  For the latter purpose, it has a spring-biased locking arm.  To the free end of the cord is secured a resilient knob and the guiding and locking device has an inclined end wall for cooperation with said knob to cause the latter to take an inclined position in its uppermost position.  The lock arm may also have a resilient cord braking element.  In the rolled-up position of the screen, the tubular member is spaced from the window frame to make room for the screen.  During unrolling of the screen, the tubular member moves towards the window frame and the screen comes in contact with the window frame to provide effective light and heat shielding.  The sleeve ensures proper cord winding on the pulley.

Abstract: ABSTRACT OF THE DISCLOSURE               The envelope feeder apparatus of the present invention is suitable for use with conventional mail sorting machines.  The envelope feeder apparatus is capable of receiving a supply of envelopes on a feeder magazine which is incorporated into the body of the apparatus.  The individual envelopes are picked off in succession at a feeder station by means of a suction device which operates in combination with a pair of conveying belts having a friction surface facing the incoming envelopes. The suction device acts through holes in the conveying belts to draw the lead envelope against the friction surface of the conveying belts for separation of the lead envelope from the rest of the supply. The separated envelope is then conveyed through an arcuate path and introduced into a transport channel which is positioned parallel to the feeder magazine of the apparatus, Within the transport channel, the envelope is transferred to a read station where the envelope is held in a stationary position until a sort code or other identifying data on the envelope is read by the operator of the apparatus.  At the read station, the envelope is held in a stationary position such that the operator of the apparatus has an unobstructed viw of the side surface of the envelope,  From the read station, the envelope is advanced to the sort bins of the machine through a transport channel which is also parallel to the feeder magazine.
