Title: Aryl Sulphones
IPC: C09B29/095
Filed: 1981-06-19
Abstract: Naphthyl sulphones of the formula:   <IMAGE> wherein Yn represents 0 to 4 substituents each independently selected from Cl, OR and SO3H where R is C1-4 alkyl;  X is CN, CH2NH2, CONH2, CO2H or CO2R;  R<1> is H or C1-4 alkyl;  R<2> is H, C1-4 alkyl, cycloalkyl, or optionally substituted phenyl;  a and b are each independently 0 or 1 and a+b is 1 or 2. The above sulphones are valuable dyestuffs intermediates and as appropriate to an individual structure can serve as diazo or coupling component. When X is CH2NH2 the sulphones of formula (1) can be used to produce valuable cellulose reactive dyes by reaction of the NH2 group with conventional reagents for the introduction of a cellulose reactive group before or after the sulphone or formula (1) is converted to a dyestuff.

Title: Reversible latch bolt assembly for a closure
IPC: E05B63/04
Filed: 1982-01-29
Abstract: A latch bolt 13 is mounted in a casing 10 for movement between relatively extended and retracted positions, in both of which a tongue 14 of rectangular cross-section extends through a corresponding rectangular aperture 12 in the casing front wall. A tail portion of the latch bolt 13 is rotatably received in a collar 32 and is normally keyed for movement therewith, but can be released for limited axial movement relative to the collar 32 by depressing an operating plate 36. Such limited axial movement relative to the collar 32 causes the tongue 14 of the latch bolt 13 to extend right out of the aperture 12, enabling the bolt 13 to be rotated through 180 DEG  whereupon its tongue 14 can be returned into the aperture 12. The hand of the latch bolt assembly can thus be changed with the minimum of effort and inconvenience. <IMAGE>

Abstract: Respective proportioning values, rendered inoperative on failure in one circuit are provided by a hydraulic braking pressure control device for a dual braking system including a pair of first and second hydraulic lines (L1, L2) extending from a dual type brake master cylinder (M) to the front and rear wheel brakes. The device includes a common housing mounted across the first and second hydraulic lines, and a pair of differential pistons (91, 92) slidably received in the aligned cylinder bores (71, 72) in the housing to respectively define on their opposing faces a first input and a first output hydraulic chamber (181, 191) and a second input and a second output hydraulic chamber (182, 192), the adjacent input and output chambers being in communication with each other through respective valves (231, 232) which are operated by movement of the pistons against the urging of a common pressure control spring (12) arranged between the differential pistons. Valve actuating pistons (111, 112) slidably disposed in bores in the differential pistons (91, 92) are each operatively connected with the valves through a pair of connector assemblies (C1, C2) each comprising two opposed members (33) (Fig. 4) with a predetermined amount of free displacement distance formed therebetween so as to allow free movements of the differential pistons within a definite range. On failure in one circuit the valve element (23) of the other circuit is held away from seating in its differential piston by movement of the pistons (111, 112). <IMAGE>

Title: Bellows
Inventor: GROPP REINHARD
IPC: F16L11/15
Filed: 1982-07-28
Abstract: One-walled bellows of metallic material for absorbing axial, lateral and/ or angular movements which, in contrast to conventional bellows, consist of cast metal. Alterations in the wall thicknesses are thereby no longer, as previously, predetermined by the manufacturing method but may be selected in such away that they may be optimally adapted to the material stress prevailing in the bellows undulation. In the case of undulating regions which are predominantly under compressive stress the wall thickness is increased; in the case of undulating regions which are predominantly under tensile stress the wall thickness is decreased.

Title: Just nails
Inventor: DAVIS BARBARA
IPC: A61K8/92
Filed: 1982-11-03
Abstract: The compound is in the form of a liquid or paste that if applied nightly to the fingernails and cuticles will cause the nails to become much stronger and in consequence to grow much more readily. The product contains Coconut oil, Lavender oil and Glycerine and is therefore harmless to health. The active ingredient in the product is the coconut oil. Other oils, colouring or perfume can be added but this does nothing to improve the basic element. Many people have tested the compound over the last year all have had satisfactory results.

Title: Branch instructions in digital computers
Inventor: DITZEL DAVID ROGER
IPC: G06F9/32
Filed: 1983-08-17
Abstract: Two consecutive instructions are transferred from the main memory of a computer to an instruction fetch unit. Each instruction comprises an op code, an operand, and an address field for indicating the address of the next instruction. The two instructions comprise the current instruction and the next sequential instruction, when the next sequential instruction is a branch instruction, the branch is eliminated by including the target of the branch in a next address field which is made a part of the previous instruction. By this method, the need to execute separate branch instructions is substantially eliminated.
