Abstract: 48D-288 Can Abstract A system of bypass passages adjacent bearing means in the drive system of an ultracentrifuge which operates in a vacuum environment.  The bypass passages or channels are designed to prevent the establishment of a pressure differential across the bearings in the drive system when a vacuum is being pulled or exists around the drive system when it is operating.  The unique bypass system prevents the loss of lubricating material within the drive system during air evacuation of the drive system and the rotor chamber when a vacuum environment is being established within the rotor chamber.  Also,  the bypass system promotes a more uniform and constant flow of lubricating medium in the bear-ings.

Abstract: ABSTRACT OF THE DISCLOSURE           A cosmetic dispenser is disclosed which includes a socket having a dispensing opening and three orthogonal axes, one axis extending through the socket and the other two lying substantially in the plane thereof.  An applicator member is retained in the socket and has an upper portion extending ex-teriorly of the dispensing opening and a skirt portion substan-tially retained within the socket.  The applicator is adapted for rotation about the three axes, but stop means limit rotation of the applicator member about the two axes in the plane of the socket.  In this manner when rotation occurs about the axes of limited rotation, the dispenser is operable to feed cosmetic across the skirt portion to the upper portion of the applicator member for application to a surface to be treated with the cosmetic.

Abstract: PROCESS FOR PREPARING LOWER ALCOHOLS            ABSTRACT OF THE DISCLOSURE:         Lower alcohols are prepared by hydrating the corresponding olefin in an aqueous solution containing a chromium compound, phosphoric acid and heteropolyacid. phosphoric acid has a high catalytic activity for the hydration of lower olefins, but causes a remarkable corrosion to an apparatus material under the state of an aqueous solution.  The catalytic composition consisting of phosphoric acid and heteropolyacid is improved in activity and stability.  Owing to the coexistence of heteropolyacid an acid degree is raised, nevertheless the corrosion of apparatus materials is not increased.  As an anti-corrosive a chromium compound is incorporated into the aqueous solution containing the catalytic composition of phosphoric acid and heteropolyacid.

Abstract: METHOD AND SYSTEM FOR RETRANSMITTING         INCORRECTLY RECEIVED NUMBERED FRAMES             IN A DATA TRANSMISSION SYSTEM              Abstract of the Disclosure A method and a system for the retransmission of in-correctly received frames in a transmission system in which information is transmitted in the form of sequen-tially numbered frames.  Each information frame includes a so-called send sequence number, N(S), a bit, R, in-dicating if this information frame has previously been retransmitted, and an information field containing the information to be transmitted.  At the transmitting station, a variable V(T), whose value is representative of the order in which a frame is re-transmitted relative to the sequence of frames transmitted for the first time, is associated with each retransmitted frame.  At the receiving station, the incoming information frames are checked for errors and the N(S) of frames found to be incorrect is noted.  The receiving station then sends to the transmitting station a so-called Checkpoint (CP) message containing a so-called receive sequence number, N(R), representative of the send sequence number, N(S), of the most recently received, non-retransmitted, error-free information frame, and, if at least one incorrect frame has been received, at least one identifier, N(X), representative of the N(S) of the incorrect frame whose retransmission is requested.  Upon receipt of the Check-point message, the transmitting station retransmits re-quested information frames that have not been previously retransmitted; it also retransmits previously retrans-mitted frames, only if the V(T) values associated there-with are less than the receive sequence number, N(R), contained in the CP message; and it updates the V(T) value associated with each frame thus retransmitted.          In a preferred embodiment of the invention, the Check-point messages are transmitted on a periodic basis.          Each of these contains an X bit whose value indicates whether the values between N(R) and the highest N(X) are also to be considered as N(X) values.

Abstract: A B S T R A C T            A METHOD FOR PRODUCING A GRINDING- OR POLISHING DISC AND A MACHINE FOR THIS PURPOSE.            A grinding- or polishing implement can be produced by providing a rectangular sheet (1) at both sides with segments (2), formed by slits from the outside towards the centre. Hereafter the sheet is folded a-round the centre across a glue string (5), and then the two folding edges are folded together and glued together for the formation of a closed ring. This ring can thereafter be placed on a spindle (6) preferably between retaining discs (8).            In this way raw material can be saved in the produc-tion of rings, just as the rings can be used more eco-nomically in an implement as the grinding qualities are improved through the big number of segments, their completely uniform size and placing along the peri-phery of the implement and their ability to adjust and shape themselves according to the prepared members.            An implement can be produced by disposing such rings between retaining discs (8) on a rotating spindle (6), and in order to secure the rings the spindle (6) can at its end have one or more  guide  facings (10), in which a co-operating guide pin (12) on a disc (7) can slide and be axially displaced by being tightened to-gether with a bolt (11).

Abstract: Abstract of the Disclosure An improved method and apparatus for forming cast-in-place structures includes the use of a sheet of fabric having a plurality of pockets for receiving support rods.  The pockets are formed between an inner side surface of the sheet of fabric and a plurality of strands of material.  The support rods are used to hold the fabric in place while a slurry of a cementitious material is poured into a cavity between the sheet of fabric and a base.  The cementitious slurry flows between the strands of material into the support rod receiving pockets.  The resulting concrete structure extends around the support rods to prevent them from being exposed to the environment.  The strands of material are advantageously connected with the sheet of fabric by inter-weaving them with the threads of the fabric.
