Title: Reversible drive unit of agricultural machine
IPC: A01D69/00
Filed: 1980-08-14
Abstract: An agricultural machine is equipped with a safety system for the avoidance of accidents concerning, and damage to, a driven operating device.

Title: Defining sets of sheets
IPC: G03G15/23
Filed: 1980-09-12
Abstract: In apparatus in which sheets are separated from the bottom of a first set in a tray whilst a second set is being stacked thereabove, a removable set separator (201), locatable between the sets, is provided.

Title: Sheet handling apparatus
IPC: B65H31/20
Filed: 1980-10-29
Abstract: A machine for cutting sheets of paper and farming them into stacks has two stocking devices (226, 227) which alternately form stacks. Each of the stacking devices includes a platform (1) which descends as a stack being formed on it grows higher, and is so constructed that its length can be varied according to the length of sheets to be stacked. The platform is made in two or more sections each hinged to the next, and all sections are supported horizontally to receive long sheets; less than all the sections being horizontal and the remaining sections hanging vertically when shorter sheets are being stacked. Wheels may be provided on the platform so that it may easily be moved out of the stacking device when loaded, all the sections being restored to a horizontal position for such movement. The machine is also provided with a cutter (214, 214a) which cuts rejected sheets into narrow strips which are then conveyed away from the machine by a conveyor (216). Alternatively the sheets may be slit longitudinally into strips. <IMAGE>

Title: Wall tie
IPC: E04B1/41
Filed: 1981-04-09
Abstract: A wall tie consists of two end portions 11, 12 shaped respectively for incorporation in a horizontal and a vertical mortar joint.

Title: Railway bogie
IPC: B61F5/04
Filed: 1981-06-02
Abstract: A railway bogie comprising a bolster secured between two side frames, the bolster ends defining an open ribbed structure nestling in a depression formed in each side frame with the end surface of each rib being secured to the frame by welding.

Title: Combining chemical reagents
IPC: G01N35/08
Filed: 1982-01-11
Abstract: The invention is a method of combining chemical reagents and comprises the steps of:   1) Dispensing the reagents into a conduit system in the form of discrete volumes or droplets separated from each other by an inert immiscible liquid, and 2) Moving the inert liquid and discrete droplets in such a manner that predetermined discrete volumes coalesce with each other, thereby combining the reagents. The preferred apparatus for carrying out the method comprises a plastic block (2) with indentations (3) which is clamped against a glass plate (4) forming closed conduits which are connected to reservoirs of light mineral oil, or silicon oil, by thin tubing (9) and valves (10). All the conduits are initially filled with the oil, then the second and fourth tubes are used to introduce two reagents, which are separated into two smaller volumes at the 'T' junctions then these smaller volumes are merged at the 'Y' junction by withdrawing oil from the center conduit.   <IMAGE>

Title: Process for treating spent sulfuric acid streams from the olefin hydration reaction
Inventor: KNUDSEN GEORGE ANDREW
IPC: C07C27/00
Filed: 1982-11-19
Abstract: A spent sulfuric acid stream formed in the catalytic hydration of an olefin to prepare an alcohol, and containing organo-sulfonic acid impurities, is contacted with an oxidizing agent selected from ozone, hydrogen peroxide, sources of chlorate and peroxydisulfate, and mixtures thereof, the oxidizing agent being employed in an amount of less than one complete oxidation stoichiometric equivalent of oxidizing agent for each equivalent of the sulfonic acid impurities, to form partially oxidized organic compounds therefrom and thereby provide a sulfuric acid stream of increased thermal stability. The process permits continuous operation at levels of total organic carbon in the treated acid which would otherwise be unacceptable and minimizes the substantial operating problems associated with formation of heavy carbon deposits in the process equipment.
