Title: Improvements in or relating to fish dressing machines
IPC: A22C25/14
Filed: 1937-09-24
Abstract: 496,314. Dressing fish. LASSEN, W. O. Sept. 24, 1937, Nos. 25976, 25977, and 25978. Convention dates, Oct. 23, 1936,. March 1, 1937, and June 25, 1937. [Class 28 (ii)] In a machine for eviscerating fishes, without decapitation, the fishes are placed singly, and belly upwards, in troughs 2 on a continuously moving conveyer 1, and the eviscerating tool 14 participitates in the conveying movement during the removal of the viscera. The throats are cut by a dagger-like implement 3, or by a rotary disc knife driven electrically or otherwise, and adjustable as regards depth of cut and also longitudinally of the fish, im. mediately before the operation of the tools 14 which are each adjustably mounted on a rod 15 slidable in a bearing 16 pivoted at 17 to a rotor 6 revoluble with the end sprocket of the conveyer 1. The bearings 16 are swung by rollers 23 engaging a stationary cam groove 10, and the rods 15 are reciprocated in the bearings by rollers 21 engaging a cam track 8 in a stationary member 20. The member 20 is axially adjustable to present the tool 14 properly to the fish, by a hand wheel 26. In operation, the throat of the fish having been cut, the snout is held against the trough by a pivoted plate 4 which is one of a number mounted on a member 13 revoluble with the conveyer sprocket, and having rollers 29 running in a stationary cam groove 5. The tool 14 then descends upon the cut and is pulled longitudinally of the fish over the snout thereof. When the trough 2 has reached the bottom of the sprocket, the plate 4 is released, allowing the fish to drop out of the trough. To prevent damage to the gill flaps, the tool 14 may be provided with inclined deflectors 50, 51, and a central recess in the bottom edge of the tool prevents it from damaging the backbone. The rods 15 are prevented from turning by auxiliary rods 19 sliding in the bearings 16. The troughs 2 may each be in one piece, or, as shown in Fig. 9, the sides 31, 32 of the trough may be hinged at 33, 34. The sides may be opened and closed by hand, but, as shown, the side 31 has a depending arm 37 which contacts with a cam face 42 on an L-shaped arm 40 on the side 32, and a spring 38 is arranged constantly to urge the sides 31, 32 towards one another. The sides are separated by the engagement of the arm 40 with a stationary cam 43, the separation and closing of the sides being effected symmetrically.

Title: Improvements in or relating to vacuum braking systems
Inventor: PAGE WILBUR MILLS
IPC: B60T13/565
Filed: 1958-08-13
Abstract: 860,202. Fluid-pressure brakes. CLAYTON DEWANDRE CO. Ltd. Nov. 13, 1959 [Aug. 13, 1958], No. 26033/58. Class 103 (1). A braking system includes a vacuum suspended servomotor having its cylinder extended to form a vacuum reservoir, the servomotor being controlled by valve means carried by the servo-piston and controlled mechanically by a pedal, the servo-piston thrust being transmitted by means disposed within the reservoir to a master cylinder. The extension 1a of cylinder 1, constituting the reservoir, houses the linkage 5, 6, 9 connecting piston 2 to master cylinder piston 10. A rod 3 is connected to a pedal and to a sleeve 15 fixed to a diaphragm 14 mounted in chamber 13 of piston 2. A boss 17 on piston 2, has a bore 19 connected via a flexible hose 18 to atmosphere and has a seat 20 normally engaged by a valve 22, a seat 23 formed on a sleeve 21 fixed to diaphragm 14, being normally spaced from valve 22. In the brake release position as shown, vacuum is communicated from reservoir 1a via port 24, past valve seat 23 and port 27 to the rear servomotor chamber and via port 28 to the chamber in front of diaphragm 14. On brake application, rod 3 moves diaphragm 14 and sleeves 15, 21 to the left to first engage seat 23 with valve 22 and then raise valve 22 from seat 20 to admit atmospheric pressure to the rear servomotor chamber via port 27 causing piston 2 to move and actuate the master cylinder. Atmosphere passes through port 28 to act on diaphragm 28 to oppose its movement to the left and so transmit " feel " to the pedal and operator. The follow-up movement of piston 2 establishes a lap position wherein valve 20 engages both seats 20, 23. On failure of the servomotor, movement of rod 3 eventually causes shoulder 29 on sleeve 15 to abut a stop 30 on a piston extension 16 to operate linkage 9, 6, 5 mechanically. In an alternative arrangement link 5 may be pivoted to the end wall 8 and link 6 to extension 16.

Patent GB-413150-A (GB)
Title: Improvements in or relating to the production of fabrics
IPC: D06Q1/02
Filed: 1933-09-28
Abstract: Fabrics having ornamental effects are obtained by treating with nitric acid at a concentration below 60 DEG  Tw. fabrics containing yarns of an organic derivative of cellulose and carrying locally thereon a substance acting as a resist to the action of the nitric acid; the said yarns are thus subjected to shrinkage throughout the unresisted areas.  The resists may be pastes containing paraffin wax, carnauba wax, beeswax or other waxes, oils, pigments &c and may contain thickeners such as gum tragacanth or gum arabic, e.g. an aqueous paste containing a gum in high concentration may be used. The pastes may be applied, preferably at 60--100 DEG  C., by means of engraved or embossed rollers or blocks or by brushing or spraying through stencils.  The nitric acid may be applied by a bath treatment, by spraying or by padding, the temperature employed being 0--60 DEG  C. depending on the concentration of the acid and the duration of the treatment.  The lustre of the cellulose derivative yarns may be diminished by the action of the nitric acid and titanium oxide; lithopone or other pigment may be incorporated in the resist paste to impart a subdued lustre to the resisted areas.  The nitric acid is subsequently removed, e.g. by washing with dilute solutions of ammonia or other alkalies.  The resist paste is also removed.  The following examples are specified: (1) a resist paste containing gum tragacanth, paraffin wax, carnauba wax, lithopone and white mineral oil is applied hot to a satin or taffeta fabric, consisting wholly of cellulose acetate yarn, by means of a roller with a deeply engraved design; the fabric is then padded at room temperature with a nitric acid solution of 38 DEG  Tw. and, when the acid has been on the fabric for about 30--60 seconds, is passed first through cold water, then through a dilute ammonia solution, and is finally scoured and dyed or otherwise finished; the resisted areas show a cockled or puckered effect; (2) the resist paste in (1) is replaced by one comprising a concentrated aqueous solution of gum arabic to obtain a similar result.  The Specification as open to inspection under Sect. 91 comprises also the use of shrinking agents other than nitric acid, such as aqueous solutions of zinc chloride and thiocyanates, e.g. potassium or ammonium thiocyanate, acetic acid, formic acid, lactic acid, diacetone alcohol, acetone, ethers, esters or ether-esters of olefine or polyolefine glycols, e.g. glycol monoacetate, methyl glycol monoacetate, dioxane and ethylene methylene ether, phenols, mono-di- and tri-acetins, ethyl lactate, diethyl tartrate, methylene or ethylene chloride, dichlorethylene, chloroform, tetrachlorethane, and ethyl acetate.  Some of these shrinking agents are suitably applied in conjunction with a diluent, e.g. benzene, toluene, xylene, benzine, petroleum ether, kerosene, carbon tetrachloride, trichlorethylene, perchlorethylene, alcohols, glycols, glycerol or water.  This subject-matter does not appear in the Specification as accepted.

Convention dates, Sept. 15, 1933 and Nov. 14, 1933. [Class 61 (ii)] [See also Group XXXVI] Pliers which cut and strip the insulation of wire are provided with a pair of jaws which first close on the work for cutting and subsequent - ly one of the jaws moves longitudinally of the wire. As shown in Figs. I and III, cutting jaws b, b<1> are pivoted together at 1 and one of the jaws carries a slide z the movement of which is controlled by means of a pair of pins and slots. The slide is pivoted to a spring- pressed link d attached to a handle 3. In operation, the jaws are first closed to cut through the insulation, and continued movement of the handle 3 moves the slide z and jaw b<1> longitudinally to strip the cable. In a modification, a pair of jaws are pivoted together by a pin running in a cam slot, the initial cutting movement of the jaws being obtained by a pivotal movement without the pin sliding, subsequent sliding taking place to move one of the jaws relatively to the other in the longitudinal direction of the wire. In Fig. X is shown a further modification in which there are two cam slots F, E, one of the handles B having a projection G, which as the handles are pressed together, initially engages a projection H, while the pin I moves part way along the slot F. On subsequent movement the projection escapes and a second pin K moves along its slot E while the jaws separate longitudinally as indicated.
