Abstract: ABSTRACT A hammer handle is made of a spring strip formed into an ob-long closed figure and a synthetic resin handle body molded around the frame.  The closed figure is interrupted at one point along the front longitudinal side.  Abutment of the free ends at the discontin-uity prevents the frame and thus the handle from flexing in one direction when the hammer claw is used, but the free ends part to permit the handle to flex in the other direction and thereby reduce the shock resulting from striking a workpiece.

Abstract: ?M-77943 DATA COMMUNICATION SYSTEM                ABSTRACT      A data communication system for use in the control and monitoring of mobile stations, for example, in a bus monitoring system, from a central station over a communication channel carrying both data and voice information.  Information is encoded into digital messages having a start code followed by one or more data blocks.  The start code identifies the beginning of the data block that follows and enables syn-chronization of clock circuitry to the received data frequency.          The data blocks have N digital words with M binary bits where one word is a parity word and N-1 words are data words.  Each of the data words has a data portion and parity portion coded for correction of at least one error.  Relia-bility is enhanced by a data detector which discriminates between data and noise or voice to provide an indication of the presence of data.  In transmitting the digital messages, the bits of the N words in each data block are interleaved to provide protection against error bursts.

Abstract: Abstract:    GAS/LIQUID CONTACT PROCESSES         In a process involving contacting a gas with a liquid whereby to cool and/or clean the gas, the liquid is sprayed into the gas by means of a rotary-cup atomiser or other "air-assisted" atomiser in which the spray is produced by impacting a film of the liquid with a high pressure air stream.  The atomiser has a low spray angle which is beneficial to ensuring good contact with the gas. The method is particularly applicable to processes where the liquid is an abrasive slurry or solution, as in a process of desulphurising a hot flue gas by spray drying in a tower.

Abstract: DRILL HAMMER WITH VARIABLE AIR CONSUMPTION Abstract of the Disclosure A drill hammer which utilizes pressurized air for reciprocating a piston to provide a percussive drilling force to the drill bit is shown.  The hammer includes a cylindrical housing having a top sub-member threadedly received therein for mating with the drill string.  The housing also defines a chamber enclosing the reciprocal piston between an upper member and the axially lower drill bit.  A spacer member is releasably attached to the upper member and within the chamber to displace a predetermined volume of said chamber. Spacer members of various volumes are provided to thereby vary the volume of the chamber in accordance with desired air consumption for the hammer.  Removal of the top sub permits withdrawal from the chamber of the top member and spacer member which are maintained together by a removable pin, permitting the spacers to be readily changed in the field for altering the consumption characteristics as dictated by drilling conditions or other variables in the field.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention provides a shuttlecock comprising a pneumatic striking cap, a connecting part fixedly attached to said cap at a location remote from that at which the cap is struck by a raquet, a feather-simulating skeleton pivotably connected to said connecting part at a lower end thereof, and extending from said connecting part in a direction away from said cap, a wind-break film attached to the free ends of said skeleton and an adjustable spring attached between said connect-ing part and said film whereby said spring tends to pull said film to a closed position and thus, said skeleton to a closed position, said film tending to move to an open position together with said skeleton on striking said cap with a raquet against the bias of said spring to control the velocity of the shuttlecock.  Thus the shuttlecock includes a pneumatic striking cap connecting part, feather-simulating skeleton, hooking spring and wind-break film, which are made of suitable materials.          After striking the shuttlecock with a raquet the velocity of the shuttlecock exceeds a limiting value, the wind-break film push the feather-simulating skeleton into an open position and opens rearwardly like a parachute and slows down the shuttlecock.          When the velocity of the shuttlecock is beneath a certain limit-ing value, the hooking spring pulls the feather-simulating skeleton inwardly and the wind-break film closes.  The fluores-cent pigment on the shuttlecock provides a variety of colors and indicates a striking direction to the player and the poor visual conditions.

The exhaust air is treated with a water circulation system to remove paint solids, a proportion of the solvent vapors passing into solu-tion with the treatment water.  A solvent stripper is provided consisting of an arrangement for applying a vacuum to the water circulated from a paint solid removal unit, causing the solvent to be vaporized out of solution, with the vapors condensed by being passed over cooling coils in a condensing chamber. the air and water stripper condensing chambers are purged by a vacuum pump directing the uncondensed solvent vapors and non-condensables into the in-cinerator.

This develops a synchronizing drag torque component at an intermediate element which, by the action of a pair of ramp surfaces cooperating via rollers, thereby produces a clamping action at a plate-type secondary synchronizer element of high drag torque-inducing capacity.  Any excess loading on the clutch is taken direct on to balking teeth of the secondary synchronizer element, whereby the primary synchronizer element is protected from overloading.
