Title: Improvements in paper trimming devices
IPC: B26D1/18
Filed: 1929-02-05
Abstract: 333,193. Allen, J. B. Feb. 5, 1929. Traversing-cutter apparatus.-A pa-per-trimming machine has a straight-edge 20 formed of a one-piece aluminium or other metal casting which is hollow and provided with stiffening ribs 21. A disc-cutter 41 is mounted in a member 37 which is pivoted at 38 to a carriage 35 sliding on the straight-edge in guides formed by grooves and a plate 26 which is either integral with or secured to the straight-edge. A projection 62 on the carriage presses the upper part of the cutter outwards, so that the lower part of the cutter remains in close contact with the straightedge. The member 37 is provided with a handle 39 normally elevated by a spring 42 and is connected to the carriage 35 by a slot 45 and pin 44. The spring 42, secured at 43, rests at one end on the pin 44, and at the other end is passed into a slot in the carriage, so that the forward end of the spring may frictionally grip the straight-edge when the cutter is inoperative. A zinc cutting-board 34, Fig. 6, may be retained on the straight edge by clips 30 held by tensioned wires 31. Lubricating pads 56 and 54 are provided for the cutter and carriage respectively.

Etherified resins suitable for lacquers are prepared by condensing phenol or cresol or 4,4-dihydroxydiphenylpropane and/or melamine or urea with a soln. of substantially pure formaldehyde in the presence of a primary, secondary or tertiary aliphatic alcohol and from 0À2 to 1À6 moles of water per mole or phenol, cresol, 4,4-dihydroxydiphenylpropane, urea or melamine, and removing the water formed during condensation. A polyester resin having free hydroxyl groups may be added to the reaction mixture (e.g. polyethyleneglycol adipate). The formaldehyde soln. may be prepared by heating an alcoholic suspension of paraformaldehyde and calcium hydroxide at 80-110‹ C. to depolymerize the paraformaldehyde, followed by filtering.

Title: Improvements in the governing of free piston type internal combustion compressors
IPC: F02B71/04
Filed: 1943-03-13
Abstract: 598,530. Regulating air compressors. ENGLISH ELECTRIC CO., Ltd., WELSH, R. J., and YATES, H. G. March 13, 1943, Nos. 4133/43 and 367/44. [Class 8 (i)] [Also in Groups XXVI and XXVII] In a power plant comprising a prime mover 25 driven by fluid from one or more free-piston internalcombustion compressors, a fuel regulator 10a and a volumetric efficiency regulator 32 for each compressor are under the joint control of a speed governor 28 actuated by the prime mover and of means responsive to the delivery pressure of some part of the compressor device ; and a variable - ratio operative connection between the two regulators is variable under the control of the pressureresponsive means so that the higher the delivery pressure the greater is the movement of the fuel regulator corresponding to a given movement of the other regulator. As shown, the prime mover 25 is a turbine driven by exhaust gases from the combustion cylinder 1 of the compressor, which is of the opposed-piston type, but it may be driven by air coming direct from the compressor, or by a mixture of air and exhaust gases. Each power piston 4 is integral with a cushioning piston 6 and with a compressor piston 5 supplying scavenging and charging air through a pipe 15 to the annular space around inlet.ports 1a in the cylinder 1. The speed governor 28 is driven from the turbine through gearing 27 and is connected to the control rack 10a of a fuel-injection pump 10 through a lever 29, link 31 and members 34, 35, rigid with the link 31 ; the member 35 is connected to a slotted link 36 pivoted at 37 and engaged by a slider 38 on a link 39 connected to the fuel regulator 10a. The slider 38 is adjusted in the slot 36a by the pressure in the air conduit 15, acting on a piston 43 connected by a lever 41 and link 40 to the link 39. Throttle valves 32 in the compressor inlet pipes 14 are actuated by levers 33 connected to the link 31, in order to control the volumetric efficiency conjointly with the fuel supply. The slotted link 36 may be replaced by a cylindrical cam of varying contour, rocked about its axis by the link 40 and engaged by a follower moved along the cam by the link 31 from the governor 28, or the cam itself may be moved axially. In a modification, a piston such as 43 is connected directly to the fuel regulator 10a and the cylinder 44 is connected to the pipe 15 through a restriction ; the control from the speed governor 28 is effected pneumatically by attracting to the link 31 a valve which varies the area of a discharge orifice in. a pipe connected to the cylinder 44. The link 31 may be moved by a servomotor controlled by the governor 28 and the speed-regulating member of the governor may be acted upon by a pressure of the gas generator in accordance with Specification 595,117, [Group XXVI].

Patent GB-479562-A (GB)
Title: An improved method of preserving fish, frogs and the like
IPC: E01C19/28
Filed: 1937-02-12
Abstract: Fish, frogs, newts, and the like, and insects such as flies, wasps, bees, and beetles, are preserved for use as bait or as natural-history specimens or for mounting on brooches or pins by placing alive in alcohol or an equivalent preservative, e.g. ether and chloroform, the body being afterwards sealed from the atmosphere by applying a transparent waterproof cellulose or other cement or covering to retain the preservative inside the body.  Fish, frogs, newts, and the like are immersed in liquid alcohol while insects may be subjected to an atmosphere of alcohol vapour.  In an example, fish is immersed alive in surgical alcohol and left therein for a considerable period, e.g. 7 days to a month, the guts are then withdrawn and the fish packed inside with cotton wool or like materials or with a sealing medium such as cellulose cement.  The mouth is then sealed with the sealing medium.  The pickling is rubbed off the outside of the fish and the skin allowed to dry for about 15 minutes.  The fish may next be tinted with water colours &c. and the fins, tail, or other projections stiffened by applying transparent cellulose cement &c. Three or four coats of transparent cellulose cement are applied over the whole body at intervals of 20-60 minutes, the whole fish being finally dipped in a bath of the cellulose cement and allowed to dry.  The eyes may be replaced by imitation eyes consisting of small beads of a colour corresponding to that of the whites, threaded on black &c. headed pins which are inserted in the eye sockets.  Where the fish is to be mounted on a brooch, cellulose cement is applied to one side which is then applied to the bar of the pin.  When to be used as bait, spinner fins may be secured to front portion of the fish, e.g. by securing by cellulose cement in slots formed therein.  The hooks are secured to wire which has been passed through the body from head to tail prior to packing or the wire may be passed through a tube in the body of the fish. The tube may be in the form of an eyed weight.  Frogs, newts, &c. and insects may be similarly treated and in mounting on a brooch may be cemented to a holder, e.g. a frame secured to the bar pin additionally or alternatively to the body mounting.
