Title: Self-sealing paper envelope
IPC: B65D27/16
Filed: 1944-08-10
Abstract: 583,966. Envelopes. TRIGGS, W. W. (International Plastic Corporation). Aug. 10, 1944, No. 15274. [Class 146 (ii)] An envelope having on the closure flap 2 a stripe 3 of permanently tacky adhesive is prevented from premature sealing &c. by the provision of a zone 4, which is repellent to the adhesive, against which the stripe 3 is folded. As shown, the zone 4 is provided on the flap 2, but it may be provided on a foldable flap on the back of the envelope. Sealing is effected by pressing the closure flap 2 against the untreated back of the envelope. The adhesive may comprise a mixture of rubber or cellulose and resin, and the repellent a film of casein, glue, starch, or resin with which is incorporated a high percentage of a lubricant such as sodium oleate or sodium laurate.

Patent GB-839847-A (GB)
Title: Error reduction by additional control in servo mechanisms
Inventor: HUVERS MARIUS ELIZA
IPC: G05D3/14
Filed: 1956-05-17
Abstract: 839,847. Electric corresponttence control systems. HOLLANDSE SIGNAALAPPARATEN N.V. May 17, 1956, No. 15406/56. Class 40 (1). A correspondence control system for causing a receiving shaft to repeat the rotation of a transmitter shaft comprises two selsyn systems in cascade which act as LP filters to remove most of the noise content plus a proportion of the legal error signal, the latter being reintroduced by passing the misalignment signal of the first selsyn link, which will comprise both legal signal and noise, through a sharply tuned LP filter to remove the noise content, and feeding forward the remainder as an additional control signal to the second selsyn receiver. Alternatively when the mechanical servo links do not remove all the noise, the feed forward signal merely reduces the noise content. As shown (Fig. 1), the rotation of a transmitter shaft 101 attached to the A.C.-energized rotor winding 102 of a selsyn transmitter produces a misalignment signal from the receiver rotor winding 105 which is amplified at 117 to cause motor 107 to rotate shaft 106 and rotor winding 105 until shafts 106, 101 are realigned. The amplifier 117 is also fed with a ## or ## anti-hunting voltage from tachogenerator 108. The rotation of shaft 106 is transmitted via a second selsyn system to a shaft 113, the amplifier 123 for the motor 114 driving shaft 113 being fed with the misalignment signal from the second servo system, which has lost the noise and part of the legal signal from shaft 101, supplemented by the misalignment signal of the first servo system after the noise component only of the latter signal has been removed by a low-pass filter 120. A 6 or 6 anti-hunting voltage for the second selsyn link is obtained from tachogenerator 115. Hence the rotation of shaft 113 follows that of shaft 101 independently of any noise content in the value represented by the angular position of shaft 101. The correction signal for the second selsyn may be derived from the misalignment signal of the first selsyn by other means, e.g. from the tachogenerator 108, and may be applied to different forms of follow-up devices. If any modification of the misalignment signal occurs between the first and second selsyn systems, e.g. if rotor winding 109 of the second selsyn is driven by shaft 106 through an n: 1 gear, then the feed forward signal is modified in the same way, e.g. it is fed through an n: 1 step-up transformer. One embodiment (Fig. 3, not shown) shows the invention applied to a system for converting cartesian co-ordinates to polar co-ordinates. Specification 500,648 is referred to.

Abstract: 117,549. Newsom, J. F. Oct. 26, 1917. Torpedo screens; air casings and water-tight casings, non-structural; ballasting.-To protect ships from torpedo attack, a series of pontoons or caissons 2 are suspended around the hull by means of pairs of pivoted arms and tacker. They may be held close to the ship's side, or be held in an inclined position, the shaped end engaging a recess 56, or suspended quite clear of the vessel. The caissons may be fitted with manholes and loading ports 3 so as to contain freight or ballast. The apparatus may be readily disconnected, and springs may be arranged to absorb wave shocks, a shock-absorbing winding drum being used, shown in Fig. 20. A towing-cable attached to the bow and supported by booms 61, 62, 65, Fig. 13, is connected to the lower ends of the caissons by means of blocks 59 which engage members 60 so that they can be detached. The boom, Fig. 13, can be collapsed against the hull by raising the block 68 to which the arm 65 is pivoted. The block 68 is spring mounted within a. sliding carrier moving within the guide 64. The arms 4 may have bifurcated ends and be pivoted on pins mounted in blocks sliding in brackets and controlled by springs, or they may have spherical portions engaged by socket members, one of which is detachable to release the arm. The caisson is connected to the arm through a spring-controlled block 15a mounted in a sleeve 15 moved by a screw; or the block may be moved by means of chains passing around pulleys. The spaces between the caissons may be closed in by means of plates, and instead of the lower end of the caisson resting in a recess as shown in Fig. 3, intermediate projections and recesses are employed. The cables 29 supporting the arms 4 pass over drums 45, Fig. 20, which are connected to their shafts through springs 48 to absorb wave shocks. The ends of the cables are each provided with a pin or similar member 49 adapted to engage a slot 50 so that the cable may be readily disconnected.

Abstract: 1461890 Impelling tools DUO-FAST CORP 9 April 1974 [11 May 1973] 15708/74 Heading B4C A power actuated fastener driving tool comprises a head portion 22 and a handle 40, the head portion containing a driving piston 28 and a combustion chamber for igniting a compressed fuel/air mixture the chamber containing a valve 38 which contains the mixture during ignition until the pressure in volume 24 exceeds the pressure in a volume 72 above the valve whereupon the valve moves upwardly to allow the combustion gases to act on a piston 28 the rod 30 of which impels a nail 36 into a workpiece. Air is conducted by a pipe 107 and fuel, such as propane through a conduit 116, both passing through a pressure regulator 50 into the handle 40 of the tool. In the handle a manually operable valve 20 is provided which has three positions which permit introduction of fuel and air to various parts of the tool at different stages. In the first position of the valve fuel is fed to a space 104 at a relatively low pressure and compressed air is passed through a regulator valve 90 through the chamber, to the cylinder 26 as the valve 38 is in its upper position and out through vent holes 154, 158. In the next position of the valve 20 air is passed above the valve 38 to move it downwardly to tis seating position and is no longer fed to chamber 24 which is then connected through the valves 20, 90 to space 104 containing the fuel so that fuel under a relatively low pressure is fed to chamber 24. At this point the piston 28 is raised manually by inserting a rod through an outlet passage 32 and a nail 36 is inserted in said passage. The valve 20 is then moved to its third position and the supply of fuel is cut off from the space 24, air under a higher pressure enters the space 24 to mix with the fuel and when the pressures in chambers 88 and 24 are equal valve 90 closes to isolate the explosive mixture in chamber 24. Valve 90 closes since its other end is connected to the relatively low fuel pressure in space 104. When trigger 144 is actuated a glow plug 48 ignites the mixture, valve 38 moves upwards since pressure in space 24 is greater than in space 72, the ignition gases pass below the valve 38 to cylinder 26 and the nail is driven out.
