Abstract: A manually operable lawn-edge trimming implement consists of a blade-carrier, a knifing blade and a broom-stick handle by which the implement may be presented to the lawn edge and traversed therealong with the blade obliquely penetrated into the earth along the line of edge trimming. The blade-carrier acts as a clamp for removably holding the replaceable knifing blade, and the blade-carrier is supported by an axle on two wheels which are well spaced apart so as to prevent grass crushing in the lawn-edge vicinity.

Abstract: A damping mechanism for implements such as tennis rackets, baseball bats and the like, comprising an elongated vibratable member formed of an elastomeric, energy-absorbing material. One of the ends of the vibratable member is attached rigidly to the implement at a point near an anti-node, with the longitudinal axis of the member concentric with or generally parallel to the longitudinal axis of the implement. The dimensions of the member are adjusted such that the natural frequency of vibration of the member corresponds generally to the vibration induced in the implement in use as a result of striking a game ball or the like.

The compounds exhibit analgesic and central nervous system activity.

Abstract: A ship having a hold with a bottom, and a vertically positioned tank with a top and bottom standing in gravity support on the hold bottom, said tank having a portion circular in horizontal section between the tank top and tank bottom, a circular restraining wall horizontally positioned around the tank, and equally spaced from, the circular portion of the tank, and a plurality of pairs of cross-braces joined to the cylindrical portion of the tank and extending therefrom and joined to the circular restraining wall, said cross-braces accommodating expansion and contraction of the tank with temperature change while providing support against lateral movement of the tank during pitching and rolling of the ship.

Abstract: A double-valved closure for a container, particularly a beer container, comprises a cup assembly for insertion into the opening of the container and includes a tubular component of plastics material having legs between which a reaction ring can be sprung during assembly of the closure. A downtube is received in the ring and extends from the lower end of the cup assembly into the container and surrounds one of the valves and a spring biasing the valve closed. The valve is carried by the top of the downtube and the reaction ring provides an abutment for the spring for this other valve and which biases the valve closed. The legs are held together after insertion of the reaction ring by means of an outer ring engaging external grooves in the legs.

Abstract: A comestible material, such as seafood, is given a scallop flavor by the addition of a compound containing a dimethylthio group, such as a S-methyl methionine salt, acceptable in foods.

Abstract: Asymmetrical, biodegradable insecticides having the formula: ##SPC1##Where R and R' are different and R is selected from the group consisting of --CH.sub.3, --CH.sub.3 O, --C.sub.2 H.sub.5 O, --C.sub.3 H.sub.7 O, and R' is selected from the group consisting of --3, and --3; and methods for providing and selectively controlling the biodegradability of DDT analogue insecticides.

Abstract: A rinsing system for steel strip after acid pickling comprises a plurality of consecutive adjacent rinse compartments, each of which contains a bath of rinse solution which is sprayed onto the strip as it passes through the compartment. Fresh water is added to the last compartment and a volume of solution equivalent to the added fresh water is continuously transferred from each compartment to an adjacent compartment. A concentrated waste rinse effluent is removed from the first compartment.

Abstract: A rear-entry ski boot comprising a semi-rigid shell is provided with a two-piece liner system, one section of which covers the forward portion of the user's foot from behind the ankle bones, the second section covering the heel and Achilles' tendon areas, the sections cooperating to cover the entire surface of the wearer's foot within the shell. The liner sections are not interconnected, and at least the second section is readily removable and replaceable. By selection of an appropriate rear section, a custom fit can be more easily achieved, and changes in the wearer's foot size, as in the case of children, can be readily accomodated.

Abstract: Method and apparatus for enabling the observation of a physical reaction occurring over many orders of magnitude in time including sensing information during a kinetic action and providing a corresponding output signal, integrating the output signal over periodic linear time segments, converting the information into digital form, and averaging the periodic information samples over exponentially increasing time intervals, each containing a plurality of said linear time segments. A digital signal averager with logarithmic time base in which analog signal information derived for instance during a physical reaction is converted into digital form in periodic samples of discrete linear time intervals, and including means for summing the samples over time intervals increasing by a fixed power, for instance two, and means for dividing the sum for each of the increasing time intervals by the number of linear time intervals in each of the increasing time intervals.

Abstract: A collapsible luggage carrying device is provided having a triangular telescoping back portion and a triangular luggage supporting base section connected thereto. Both the back and the base include elongated tubular frame members diverging from a common apex and being interconnected by a generally transverse connecting and stabilizing bar which maintains the triangular shaped back and base portion in a rigid, expanded position for carrying luggage. The base may also include a plurality of sections telescoped together to thus provide an adjustable length for accommodating several pieces of luggage. The apex of both the upright back portion and the base are interconnected with a flexible strap to provide an enclosed rigid triangular supporting frame surrounding the articles being transported.

Abstract: A pipe support having a frame, a lever pivoted to the frame, elongated resilient means whose ends are engaged by first and second abutments respectively, the first abutment being pivoted to the frame, a draw bar slidably mounted in the first abutment and having its opposite ends connected to the lever and to the second abutment respectively and load attachment means for attaching a load to the lever. The load attachment means is connected to the lever in such a manner that when a load is supported the lever is urged in opposite directions about the lever pivot by the load and resilient means so that the load is supported by the resilient means, and complementary means are provided on the draw bar and the first abutment which can be engaged so that sliding movement of the draw bar relative to the first abutment is prevented and the draw bar is held in a selected one of a number of positions relative to the said first abutment.

Synthesized products are isolated and quantified.

Abstract: Organic compounds containing both an amino group and a carboxylic acid group are reduced when treated with boron trifluoride followed by diborane, a borane-ether or borane-organic sulfide complex. The presence of the boron trifluoride is responsible for an increase in the rate of reduction of the carboxylic acid group and eliminates the need for the large excess of the borane complex normally required due to the competing formation of boron-nitrogen compounds. Hydrolysis of the reaction mixture provides a useful and convenient method for separating the corresponding amino alcohol.

Abstract: Process for receovering copper values (and zinc, if present) from copper bearing materials, optionally in admixture with iron. The feed material is leached with a mixture of nitric and sulphuric acids, after which the dissolved copper is cemented from solution by contact with iron. The solution, containing dissolved iron (and zinc, if present in the feed material) salts is reacted with ZnO to precipitate iron as ferric oxide, which is separated, leaving zinc sulfate in solution. Solid zinc sulfate is recovered from the solution by evaporation, and then calcined to produce SO.sub.2, which is recovered and recycled as H.sub.2 SO.sub.4, and ZnO, which is reused in the process, any excess being recovered as a product.
