Abstract: PRODUCTION OF IMPROVED PREIMPREGNATED MATERIAL COMPRISING A PARTICULATE THERMOSETTING RESIN SUITABLE      FOR USE IN THE FORMATION OF A SUBSTANTIALLY VOID-FREE FIBER-REINFORCED COMPOSITE ARTICLE               Abstract of the Disclosure An improved multifilamentary fibrous material is formed having solid particles of a matrix-forming thermosetting resin substantially uniformly dispersed among adjoining filaments in the absence of fusion bonding.  The thermosetting resin particles initially are dispersed in an aqueous medium containing an effective amount of a dissolved polymeric binding agent and the viscosity of the medium subsequently is substantially increased to at least 50,000 cps. to form a gelled impregnation bath having a plastic flow characteristic with shear-thinning behavior wherein the thermosetting resin particles are substantially uniformly suspended.  The resulting impregnation bath is caused to flow between the adjoining filaments of the multifilamentary fibrous material with a concomitant viscosity reduction which aids in the incorporation of the resin particles.  The concentration of the aqueous medium in the product is controlled to yield a uniform, handleable, drapable, tacky, and highly stable product.  upon the application of heat and pressure the improved product can be transformed into a fiber-reinforced composite article wherein the thermosetting resin forms the matrix phase.

Patent CA-1326118-C (CA)
Inventor: LUPKE MANFRED A A
IPC: B29C48/09
Filed: 1988-12-20
Granted: 1994-01-18
Abstract: The invention concerns apparatus for molding thermoplastic tubing, especially ribbed and double walled thermoplastic tubing. In such apparatus a sizing plug, which may be of a cooling plug, is often provided to define the inner wall of the tube. According to the invention a pressured gas is expanded isentropically into the cooling plug through a throttle valve so that the expanding gas cools the plug. Suitably the gas is carbon dioxide which may be vented to the atmosphere. The use of a throttle valve for isentropic expansion of gas to cool the plug, is advantageous at least in that the degree of cooling may be controlled through the degree of throttling of the valve and in that gas may be led into the valve at the temperature of the molding process, rather than through cooling lines which may have localised undesirable cooling effect. The invention also includes providing the plug with a porous outer region for the dissemination of lubricant.

Title: Punch-type vote recording device and punch therefor
Inventor: RAPP TOD A
IPC: G07C13/00
Filed: 1989-01-31
Granted: 1993-02-09
Abstract: Abstract of the Disclosure A vote recording device and punch permits the utilization of non-scored ballot cards.  The vote recording device employs an intermediate lock-out template beneath the top mask which is moved by the card into a position in which openings formed in the template are in alignment with openings form with the mask and which together are in alignment with smaller openings formed in a bottom shear plate.  A punch includes a cutting stylus which is normally received within a retractable sleeve. The sleeve is proportioned to be received through the aligned openings in the mask and template and bears on a voting card so that depressing the punch runs the cutting stylus through the card and through the aligned opening in the shear plate to remove a chip of the card, thereby forming a clean hole in the card.  The extent of movement of the sleeve on the punch is controlled to prevent scoring or punching of the card, if the card is not fully and properly in place.          The tip of the stylus is formed with diametrically opposed cutting points joined by curved cutting edges between the points, the cutting edges being staggered or offset with respect to the axis of the stylus so that cutting of the card takes place primarily along one of the curved edges and then along the other curved edge.

Abstract: ABSTRACT OF THE DISCLOSURE     A copying machine control apparatus which includes a first control means for actuating a first driving means which operates a  photoconductive  drum,   a second control means for actuating a second driving means which operates a scanning means, and a third control means for actuating a third driving means which operates a transfer drum.   Each of first,  second,  and third control means has a position controller and a speed controller, respectively, operated by a common reference pulse train,  in which the position controller generates a position control signal to indicate the  turning position difference at any  moment, and the speed controller generates a speed control signal which is composed of   a frequency difference between the common reference pulse train and the pulse train outputted from respective pulse encoders, then this speed control signal is added to the position control signal to generate a driving signal which actuates each of first,  second,  and third driving means, respectively.   Thus, the first, second, and third driving means are harmoniously operated by  the common reference pulse train.  In the case where each of the first and third driving means is   constructed by an outer-rotor type electric motor,  each of  the  photoconductive  and transfer drums is  rotated by the outer rotor of the electric motor.
