Title: Brushing machine for skins - uses barbed conveyor bars to pull skins between rotating brushes
IPC: C14B1/44
Filed: 1973-07-19
Abstract: Machine for brushing simultaneously the two opposite faces of a sheet or pliable matl., such as an animal skin, by conveying it between two parallel cylinder brushes rotating to oppose the conveyor and at circumferential speeds in excess of the conveyor speed. The conveyor comprises a parallel pair of spaced, endless chains joined by spaced, parallel cross bars each with a set of sharp fine barbs on which sheets to be brushed are anchored to be pulled between the brushes. pref. the barbs which may be straight or curved, are pointed in the forward direction of the conveyor and slightly inwards toward the conveyor dead plates. Continuous mechanical feed between the brushes substantially reduces manual effort and increases output.

Title: Poppet valve with noise reduction device - has rubber washers between spring cap and intermediate spring carrier
Inventor: SOUBIS JEAN-PIERRE
IPC: F01L1/46
Filed: 1974-07-10
Abstract: The poppet valve is returned to its seat by two springs which are mounted in series with a carrier between them. A spring cap, which is secured by a split cone, has a washer of nitrile rubber bonded to its undersurface. The inter. spring carrier has a skirt which extends upwards and its end face is also provided with a nitrile washer.

Title: Filter for cleaning welding fumes - using magnetic iron trap followed by wire brush filter and then paper filter
Inventor: BOSSE ALAIN
IPC: B01D46/00
Filed: 1975-04-24
Abstract: Device for filtering fumes, esp. fumes arising from welding operations, the device possessing downstream and upstream sections, with means for fine filtration and means for prefiltration consisting of a clamped assembly of metal wires extending transversely between a long support and the internal wall of a box through which the fumes pass. The novelty is that the metal wires are compressed by the box so they are curved, and their support can be moved axially towards a larger box upstream which permits the wires to assume their normal dimension. The perimeter of the larger box is pref. fitted with magnets. Three-stage filtration is used for very effective removal of dust and finer particles.

Title: Nut on stud tightening equipment - has bridge piece between tension members supported on central ram piston (NL110576)
IPC: F16C9/02
Filed: 1975-11-06
Abstract: The equipment deals with two nuts at a time, having two tensioning members each for attaching to the end of a stud or bolt and mounted on a common bridge piece with hydraulic ram, so as to stretch the studs by moving the bridge piece in their axial direction. It is particularly for use on heavy crankshaft bearing caps. The tension members (10, 11) extend clear of the bridge piece (6), which is supported by the central ram piston (50) directly on one of the two components to be secured together. Each tension member can have an internally-threaded sleeve section (14, 15) at one end by which it screws onto the end of the stud (22, 23), and can slide in the bridge piece. It has an external thread (18, 19) on the other end, accommodating a nut (20, 21) locking it in position on the bridge piece.

Title: Tree-pruning-shears - have two hinged blades with straight cutting-edges, and handles
IPC: A01G3/02
Filed: 1976-03-16
Abstract: A counter-blade (5) with a hook (4) and handle (7) is hinged to the main blade (3) with handle (6). The hinge point (8) of the two blades is positioned on the side of the cutting-edge (9) of the main blade, so that the cutting action pulls the branches and not presses them. The angle enclosed by the two blades (3, 5) is very acute. The base (10) of the jaw between the blades is not V-shaped but wide and rounded. The cutting edges (9, 11) of the two blades (3, 5) are essentially straight. The tip of the main blade (3) overlaps the hooked-tip (4) of the counter-blade (5). A pivot-mounted (13) attachment (12) at the bottom of the main blade (3) engages into notches (14). A coiled spring (15) gives an elastic movement to the shear's opening.

Title: Clarification of lipaemic blood serum - by forming interface between sample and solvent, centrifuging and decanting solvent
IPC: A61K35/16
Filed: 1976-03-25
Abstract: Lipaemic blood serum is clarified by forming an interface between a body of lipaemic serum and a lipid-specific solvent having a specific gravity less than the serium, and subjecting the interfaced liqs. to a centrifugal field having a min. field strength of 1000 RCF for a predetermined duration while maintaining the integrity of the interface so that the solvent rides centripetally relative to teh lipaemic serum body, then removing the interfaced liqs. and withdrawing one of the resultant solvent and serum layers without disturbing the other. The method is useful for clarifying the lipaemic blood serum samples having turbidity due to chylomicrons without subjecting the serum samples to the disadvantages encountered using either centrifugation alone or extn. with specific solvents. Suitable solvents which can be used incl. opt. halogenated aliphatic or aromatic which are lipid solvents, immiscible with water and sp. gravity less than 1.030, e.G. ether, pet. ether, CHCl3 etc.

The latter have protrusions (14, 15) rigidly attached to the synthetic material sections. The aluminium sections can be manufactured quickly and economically in any colour, using for example, electrolytic oxidation. The synthetic layers provide very good insulation, and are wind-resistant. An insulating layer (21) is coated on the synthetic material layer between the projections (16, 17) which interlock with the aluminium (14, 15).

Title: Machine to strip wool from animal skins - is easily loaded and strips entire surface without damaging skin
IPC: C14B1/12
Filed: 1976-04-21
Abstract: The machine used a conveyor having twin parallel chains with transverse pivots on which are fixed spaced carriers for skins. Each carrier is in the form of a flat work table and skin is folded to saddle the leading edge of the table and trail back on opposite faces of the table. The table conveys the skin over a vertical run, upwards between rotary stripping cylinders. The table faces are covered by an endless belt which is given a limited longitudinal movement as the table passes between the stripping cylinders; this moves the unstripped, leading edge of skin on to one face of the table for stripping. The chain pivot fixings for each table are such that the table remains in the same plane as the chains on straight runs of the conveyor. As the chains pass around a pair of sprockets, the table leading edge moves radially outwards frm the sprockets' axis. This takes the leading edge clear of a skin-clamping roller which is tight against the leading edge on straight runs. Movement of the table belt is pref. obtained by fitting a toothed pinion on the front roller of the belt and arranging for the opinion to engage a short length of rack as the table passes the stripping cylinders.
