Title: Knotter
IPC: B65H69/04
Filed: 1965-11-18
Abstract: Mechanism for tying a fisherman's knot comprises two knot tying bills (54, 56) Figs. 1 and 2, not shown, a pair of clamps (80, 100 and 82, 102) and an adjustably positioned centre post (124) adapted to engage the strands whereby it is capable of determining whether the ends of the strands extending from the knot are long or short.  The two strands (Y, Z) to be looped about each other extend across their respective clamp end portions (90, 100 and 92, 102) and are directed to cross in front of centre post (124) before passing over the bills (54, 56) Fig. 6a, not shown. The centre post is capable of forwards or backwards positioning to engage the strands early or late during its subsequent movement whereby after the bills have been rotated to loop each strand about the other and the clamps have been rotated to pull the loops off the bills the slippage of the strands through each loop can be restricted to permit the end of each strand retained in the bill to be either long or short.

Abstract: 1316310 Coatings BAYER AG 19 Oct 1970 [23 Oct 1969] 49453/70 Heading B2E [Also in Divisions C3 and D1] Materials such as textiles, leather, paper, wood, metal, ceramic, stone, concrete, bitumen, hard fibre, straw, glass, porcelain, synthetic resins and glass fibres are coated with aqueous dispersions obtained by polymerising olefinically unsaturated monomers in aqueous emulsion in the presence of a free-radical initiator using, as emulsifier, from 5-95% by weight (based on the combined amount of monomer(s) and emulsifier) of one or more oligourethane salts having an average molecular weight of from 1500 to 20,000 and a foil of the oligourethane salt having a tensile strength in the dry state of less than 20 kg wt/cm<SP>2</SP>, the oligourethane salt having been prepared from water-insoluble oligohydroxy compounds having a molecular weight of from 400 to 5000, and at least the major portion of the monomer(s) used being water-insoluble. The Specification states that, in addition to their serving as emulsifiers, the oligourethane salts also modify the properties of the polymers formed, e.g. they improve elasticity and abrasion resistance and reduce the tendency of the polymers to swell in organic solvents. Examples illustrate the preparation of dispersions of polymers derived from (a) vinyl acetate, (b) ethyl acrylate, (c) ethyl acrylatestyrene, (d) styrene, (e) styrene-butyl acrylate, (f) butyl acrylate, (g) vinylidene chloride, (h) vinyl chloride-vinylidene chloride, (i) vinyl chloride, (j) vinylchloride-ethylene, (k) butadiene, (1) styrene-acrylic acid-hydroxypropyl methacrylate-acrylamide N-methylol methyl ether-butyl acrylate, (m) methyl acrylate and (n) acrylonitrile. Additives such as other polymers, fillers, plasticisers, pigments, HF and silicic acid may be included in the dispersions.

Title: Energy absorbing steering device
IPC: B62D1/16
Filed: 1971-10-26
Abstract: 1327899 Collapsible steering column TOYOTA CHUO KENKYUSHO KK 26 Oct 1971 [31 Oct 1970] 49687/71 Heading B7H A collapsible steering column includes telescopic upper and lower sections arranged to move axially in the event of a collision and a body of rigid plastics foam interposed between the upper and lower sections which is compressed upon relative axial movement of the sections to absorb the forces exerted on the steering wheel D. The rigid plastics foam may be polyurethane or polystyrene and its density and dimensions are chosen so that, on relative displacement between the sections, the load increases rapidly to a predetermined value which lies within the range in which damage to a human body is avoided and then remains constant during further displacement. In this way the maximum amount of kinetic energy is absorbed. In a first embodiment (Fig. 10) the steering shaft 5 consists of an upper shaft 51 and a lower pipe shaped shaft 52, the shaft 51 being arranged to slide axially in the pipe 52. The shaft 51 has a non-circular cross-section to transmit torsional forces to the pipe 52. The steering column tube 6 consists of upper and lower tubes 61, 62 arranged to slide axially relative to each other. Plastics material is injected in the joints between shaft 51 and pipe 52 and between tube 61, 62 to form a connection which is broken in the event of a collision. The body of rigid plastics foam 4 is located in the pipe 52 and is compressed by a piston formed on the end of shaft 51 in the event of a collision. In a second embodiment (Fig. 13) the body of rigid plastics foam 4 is located in a cylindrical casing 53 fixed to the shaft 51 and is compressed by a conical head 542 formed on a member 54 fixed to the pipe 52. In a third embodiment (Fig. 14) the body of rigid plastics foam 4 is located in a cylindrical housing 54 fixed to the upper tube 61 and is compressed by a conical head 55 fixed to the lower tube 62.

The insert has four channels 12 partly defined by end 16 of the member 4 which intersect one another at 90 and which open tangentially into a swirl chamber 11 which communicates through an orifice 10 with atmosphere. The member 4 has a skirt 13 which encloses a pre-expansion chamber. For ease of assembly the member 4 is first fitted into a smaller diameter portion 25 of the recess and the insert 3 is then pressfitted on top of the member 4 against wall 23 of the recess. Alternatively the sleeve 13 may slide inside sleeve 8 of the insert, Figure 2 (not shown) and the assembled unit of member 4 and insert 3 be inserted together into the recess, or the sleeve 13 may protrude from sleeve 8 and again fit into a portion of the recess of smaller diameter, Fig. 3 (not shown).

A sleeve (3) with a longitudinal slot (3a), Fig. 3 (not shown), is used with a percussion tool to drill its own hole (4) in masonry (2) and then there is introduced a spreadable insert (5) having a longitudinal projection (6a), bearing teeth (6b) and engaging the slot (3a), so that, when a screw (1) is screwed into threads (6c) in the insert, the projection (6a) is moved out of the slot (3a) to grip the wall of the hole (4). The insert (5) has diametrically opposed slots and an inclined surface (6d) in its bore, behind the projection (6a), so that the screw causes most of one half of the insert to be spread outwardly, Fig. 6 (not shown). The surface of the insert (5) adjacent the toothed projection (6a) is tapered at either side of the latter, Fig. 2 (not shown), to reduce obstruction of the spreading by the edges of the sleeve slot (3a).

Title: Improved process for the production of white cements
IPC: C04B7/47
Filed: 1965-12-07
Abstract: A process for producing clinkers for white cements comprises roasting in a kiln raw materials having low contents of metallic oxides, cooling the clinkers in a heat exchanger in which air intended for combustion in the kiln is preheated, heating the coloured clinkers so obtained to a temperature of 800 DEG  to 1200 DEG  C., and cooling them in the absence of air, e.g. by quenching with water or in a neutral or reducing atmosphere.  Two embodiments are described. In one, two kilns are employed simultaneously, and clinker leaving the first kiln via a heat exchanger is delivered to the second kiln (in which raw materials are being heated by the conventional process for making white cements), the total output being led to the usual quenching &c. cooler.  In the second, one kiln only is employed, part of the clinker there produced being led to a quenching &c. cooler, and the rest being recycled via a heat exchanger to the kiln for delivery thereto either at the infeed or at a hotter zone.

In an anti-skid fluid pressure brake system the pressure is cut off in response to e.g. an inertia switch wheel-lock-sensor and the pressure in the brake cylinder is reduced by a relief valve to a predetermined amount less than the brake pressure at wheel-lock. As shown, brake pressure is applied from source 11 through drivers valve 12 and cut-off valve 13 to the brake cylinders 10 and to reservoir 36 at the back of relief-valve 29. At wheel-lock inertia switch 27 energizes solenoid 24 to vent the space below diaphragm 17, allowing spool 15 to move down and shut off the brake pressure supply and connect the brake cylinders via pipes 19, 20 to the relief valve 29. Since valve 35 closes when the solenoid is energized, holding brake pipe pressure in reservoir 36, the brake cylinders are unloaded by the different face areas of the relief valve.
