Title: Preparation of meta-isopropylphenol
Inventor: OLAH GEORGE ANDREW
IPC: C07C67/00
Filed: 1983-11-24
Abstract: Resorcinol is prepared by an improved process through superacid (such as perfluorinated alkanesulfonic acids of one to eighteen carbon atoms or polymeric perfluorinated resinsulfonic acids, such as Nafion-H catalyzed cleavage-rearrangement reaction of meta-isopropylphenol hydroperoxide in the form of its protected ether or ester derivatives, including readily cleavable and reusable trimethylsilyl and trifluoromethanesulfonyl derivates. Part of the process is the preparation of needed meta-isopropylphenol in high purity free of other isomers by treating any mixture of isopropylphenol isomers in an excess of anhydrous hydrogen fluoride or a perfluorinated alkanesulfonic acid of one to six carbon atoms and a Lewis acid fluoride or by alkylating (transalkylating) phenol with a propyl alkylating agent in the presence of the aforementioned superacid systems.

Patent GB-2142127-A (GB)
Title: Firing of ceramic ware
Inventor: WHITE PHILIP JOHN
IPC: F27D99/00
Filed: 1984-06-20
Abstract: An electrically heated kiln (10) for firing ceramic ware has centrifugal fans (22) communicating with a lower region of the kiln, the fans (22) pulling atmospheric air from externally of the kiln through electric heaters (24) so that heated air is introduced into the kiln to create an airflow which passes around the ware. The air then escapes through dampers (14) at an upper region of the kiln (10). In this way the electric heating elements (16) of the kiln (10) are not required to heat the ware up to such a high temperature as is conventional in order to burn off organic binders. Alternatively the air within the kiln (10) can be recirculated (28) to be introduced by the fans (22) at the lower region of the kiln (10). <IMAGE>

Title: Accelerometer
Inventor: BUNKER CHRISTOPHER
IPC: G01P15/04
Filed: 1985-07-24
Abstract: An apparatus for measurement of acceleration or deceleration comprising a container 1 filled with liquid and containing a bubble 11. The top wall of the apparatus is provided with a series of spaced apart ridges 3-9 so that when the apparatus is subjected to either acceleration or deceleration the bubble 11 moves from a first position to a second position between two ridges, which maintain the bubble 11 in its new position when the apparatus is no longer accelerating or decelerating. The extent of movement of the bubble provides a measure of the acceleration or deceleration which the apparatus has undergone. <IMAGE>
Patent GB-852822-A (GB)
Abstract: 852,822. Calculating-machines. LANGBEIN, H., and SCHNEIDER, A. Feb. 8, 1957, No. 4417/57. Class 106 (1). A key-responsive calculating machine having a differential actuator associated with a shaft bearing radial stops for co-operation with arresting members set by the keys is adapted for a non-decimal system. An arrangement for dealing with pence is described. The machine is combined with a typewriter and, on depression of a calculating number key, a powered shaft is clutched for one revolution to a cam shaft. Keyboard.-Pivoted on a rod 3 beside an upper " 4 " key lever is a " 10 " key 1 with an upward extension 37 bent over a locking lever 39 pivoted to the " 4 " key and having a wedgeshaped end 64 for co-operation with a crowding lock for the keys. The " 4 " key is laterally bent so as to pass over the end of the lever 39. Thus, the lever 39 is depressed when either the " 4 " or the " 10 " key is depressed. A threearmed lever 27 is pivoted on the lever 39 and one arm co-operates with a bar 33 so that when the lever 39 is depressed, the lever 27 is rocked clockwise. If the lever 39 is depressed by the " 4 " key, a hook 25 of the lever 27 moves under a projection 23 of the " 10 " key to prevent its depression, whilst if the " 10 " key is depressed, a shoulder 76 of the lever 27 moves beneath a pin 78 in the " 4 " key. An " 11 " key is associated with the " 6 " key in a similar manner. The bar 33 co-operates with projections on the keys and is moved rearwardly early in a cycle of the cam shaft to lock the keys during the cycle. Differential mechanism.-Early in a cycle, a cam raises the upper end of a rack bar 90 into engagement with a totalizer driving wheel 92. A further cam then releases the rack to the action of a spring 90a which drives it leftward, rotating a shaft 51 clockwise. The shaft carries stops 52 equal in number to the radix concerned and is arrested by the abutment of one of these stops against a corresponding slide 50 raised to an effective position by the number key depressed. The rack bar 90, which has thus been differentially positioned, is then disengaged from the wheel 92 and restored longitudinally by its cam. The " 10 " key 1 raises its slide 50 by rocking a bail 44 which shifts a link 46 formed with a cam slot embracing a stud 49 in the slide 50. The " 11 " key does not operate a slide 50. When " 11 " is to be entered, the rack bar 90 is arrested by a fixed stop 103. The stops on the shaft 51 serve to select the appropriate type lever for actuation. Specifications 361,484 and 496,720 are referred to.

Title: Automatic line for production of pattern assemblies for precision casting
Inventor: BELYAEV VLADIMIR MIKHAILOVICH
IPC: B22C7/02
Filed: 1987-02-20
Abstract: An automatic pattern-cluster-making machine (1) is linked, via a device (16) for transferring the pattern clusters and slipping them onto uprights, to an installation (4) for fitting pattern clusters in an assembly. The installation is disposed close to a pattern assembly remover (68) and a vacant upright positioner (89). The automatic machine and the installation are independently cycle-operated in synchronism with respect to working stations so that the beginning of a turning phase of the automatic machine as the pattern clusters are being carried from one working station to another, coincides with the beginning of a dwell phase of the installation. The transfer device, pattern assembly remover, and upright postioner comprise cycle-operated manipulators having tong grips and operating in synchronism with respect to working stations so that their traverse toward respective working stations coincides with the beginning of dwell phases of the automatic machine and the installation. The remover and the positioner are equipped with separate storage units. <IMAGE>

Title: Underside pull-out guide for drawers or the like
Inventor: FULTERER MANFRED
IPC: A47B88/14
Filed: 1987-07-28
Abstract: The underside pull-out guide is constructed in such a way that when the drawer 6 is pulled out the pull- out rail 10 is not visible. The pull-out rail 10 is disposed below the base 8 of the drawer 6 and has a box-like cross-section into which a vertical web 5 of a support rail 2 engages from below. The support rail is secured to a lateral wall 1 or base wall of the furniture. Inside the box- like cross-section of the pull-out rail 10 the vertical web 5 passes into a horizontal web 7, on which rollers 12, mounted freely rotatably in a cage 11 and held equidistantly, bear from above and below. In order to achieve favourable stressing ratios for the support rail, the horizontal web 7 is orientated towards the adjacent lateral wall 1 of the piece of furniture or towards the adjacent lateral face 9 of the drawer 6. Lateral guide rollers 13 prevent lateral displacement of the drawer 6. <IMAGE>
