Title: Process for the preparation of dimedone
Inventor: LEHKY PAVEL DR
IPC: C07C45/45
Filed: 1982-05-12
Granted: 1985-05-23
Abstract: Process for the production of dimedone from isophorone. The isophorone is converted in the presence of a solvent with ozone into an ozone-addition product. An alcohol corresponding to the ester radical is added at the latest after the formation of the ozone-addition product for the formation of the intermediate product, 3,3-dimethyl-5-oxo-hexanoic acid ester. The ozone addition product is heated in the presence of acids to a temperature of 20 DEG  to 150 DEG  C. The 3,3-dimethyl-5-oxo-hexanoic acid ester is isolated thereby. The ester is then converted in a further step into dimedone by treatment of the ester with an alkali alcoholate in an anhydrous milieu.

Abstract: PCT No. PCT/AT82/00028 Sec. 371 Date Jun. 16, 1983 Sec. 102(e) Date Jun. 16, 1983 PCT Filed Sep. 27, 1982 PCT Pub. No. WO83/01406 PCT Pub. Date Apr. 28, 1983.An operating part, essential to the starting-up or use of a power-operated device (1), e.g. driven by an engine or a pressure-medium, is made in the form of a tool-carrier (4). Permanently attached to the tool-carrier (4) is at least one tool, preferably a set of tools, specifically intended for the maintenance, cleaning, or the like of the device. However, the operating part constituting the tool-carrier (4) is arranged detachably upon a functional element (2,3) of the device (1). It is therefore scarcely possible for the tool to be lost after it has been used, since the device (1) only becomes serviceable again (i.e. may be driven or guided by the operator) after the operating part of the device (1) which has been removed, and which constitutes the tool-carrier (4), has been replaced.

Title: Feedwater control system
Inventor: COOK BRUCE MICHAEL
IPC: G05D7/03
Filed: 1982-02-25
Granted: 1986-11-20
Abstract: Excessive swing of the feedwater (31) in power supply apparatus on the occurrence of a transient is suppressed by injecting an anticipatory compensating signal (ΔW<sub>fw</sub>) into the control for the feedwater. Typical overshoot occurs on removal of a large part of the load, the steam flow is reduced so that the conventional control system reduces the flow of feedwater. At the same time there is a reduction of feedwater level in the steam generator (13.15) because of the collapse of the bubbles (125) under increased steam pressure. By the time the control responds to the drop in level, the apparatus has begun to stabilize so that there is overshoot. The anticipatory signal is derived from the boiling power (BP) which is a function of the nuclear power (2N) developed, the enthalpy of saturated water (h<sub>.</sub>) and the enthalpy of the feedwater injected into the steam generator (h<sub>fw</sub>). From the boiling power (BP) and the increment in steam pressure resulting from the transient an anticipatory increment of feedwater flow is derived. Thus increment is added to the other parameters controlling the feedwater.

Title: Wear-resistant and shock-resistant tools and method of manufacture thereof
Inventor: GUNZNER FRED G
IPC: B23D65/00
Filed: 1982-12-09
Granted: 1987-10-22
Abstract: Wear-resistant and shock-resistant tools (14) are constructed by preforming carbide-containing working parts (10) of high wear resistance and hardness and attaching them to a softer base metal (12) of the tool by means of a highly shock-resistant steel-to-steel fusion weld. The working part (10) is preformed by powdered metallurgy techniques utilizing steel powders having carbide-forming constituents therein which form carbides along the grain boundaries of the steel uniformly throughout the working part as a result of sintering of the compressed powders. Thereafter the fusion welding process renders the carbide structure of the working part nonuniform for optimum shock resistance, without reducing the effective wear resistance thereof, while also forming a highly shock-resistant joint between the working part (10) and the base metal (12) of the tool.

Title: Protective helmet, in particular a motor cyclist helmet
Inventor: HUBER SIEGFRIED ING GRAD
IPC: A42B3/24
Filed: 1983-07-16
Granted: 1985-08-01
Abstract: A safety helmet exhibits, in the zone of the longitudinal line of symmetry of its chin protector, an upwardly projecting rubber-elastic material air duct member comprising a sealing lip. This sealing lip extends past the contact area of the visor on the chin protector to such an extent that the chin protector is in contact with the visor when the visor is opened a crack. Thus, the air stream entering the interior of the helmet is conducted toward the lateral regions of the window and cannot affect the eyes of the helmet wearer. Since the air duct member is made of a rubber-elastic material, the visor can be closed entirely. Additionally, the air duct member is provided with two lateral parts and a continuous water-conducting groove which is arranged in these parts and in the air duct member. Water can collect in the groove and be drained off in the rearward and downward directions.

Title: Constant load snap switch with manual or automatic reset, stop and test selection
Inventor: FORSELL KENNETH ARTHUR
IPC: H01H5/18
Filed: 1983-12-07
Granted: 1988-12-29
Abstract: A constant load and constant contact force snap-action switch (Figure 1) having a normally-closed movable operate contact (18) on a flipper blade (20) which has a compression strip (20c) that snaps through an S-curvature to a reverse buckled state to trip the operate contact open. The flipper blade is coupled through an insulating cap (26) to the leaf spring mounted movable alarm contact (22) to close the latter at the same time. A return spring (36) biased reset lever (32) resets the operate contacts on depression down a first amount, opens the operate contact without closing the alarm contacts on depression down a second amount for stop purposes, and trips the operate contacts open on lifting upwards for test purposes. On reset, lost motion in the coupling cap (26b) knocks the alarm contact open if welded. A selector (38) is settable to select any of three functions for the reset lever, (1) reset-stop-test, (2) auto reset stop, or (3) reset test.

Granted: 1989-06-29
Abstract: A chop saw (90) pivotably mounted for movement between a raised rest position and a lowered operational position, having a motor driven saw-blade (32) rotatably supported about a shaft (28), with a saw housing (106) partially encasing the saw-blade (32) and a swinging blade guard (108) which covers the exposed segment of the saw-blade (32) when the saw (90) is in the rest position. When the saw (90) is lowered to its operational position, a linkage system comprising four effective levers and four hinges clears the blade guard (108), thereby exposing the saw blade (32) to the work piece. To accommodate changing the saw blade (32) while the saw-unit (90) is in its rest position, the effective length of one of the levers can be temporarily reduced, thereby clearing the blade guard (108) from the exposed section of the saw blade (32). This provides easy access to the saw-blade (32) to be changed.
