Title: Improvements in or relating to power chain saws
IPC: B27B17/00
Filed: 1948-08-06
Abstract: 657,819. Chain saws. QUIRKE, A. T. Aug. 6, 1948, No. 7899. Convention date, Feb. 12. [Class 145(ii)] In a power chain saw, of the type in which a chain, driven around a stationary guiding blade, carries the requisite cutting teeth, and the guiding blade has attached to its outer end a handle assembly carrying an idler wheel for the chain, the idler wheel is normally held and tensioned from the handle assembly which may be removed leaving the idler wheel supported by the guiding blade so that the saw may be withdrawn longitudinally through the cut. In the form described, a main housing 1 is attached to the guiding bar 3 of the saw by a clamping means 5 and surrounds the idler pulley 2. The pulley axle is carried by a yoke 7 which is slidably mounted in guide slots 8 in the casing 1. Pivoted to a handle-grip 4, and attached to the yoke 7, is a lever 13, the pivot 13a being so offset that the tension in the chain keeps the lever within the handle. The link 14 is attached to a sliding nut member 15 within the lever 13 so that the tension in the saw may be varied by rotating the kurled head 16a. The clamping means consists of a releasable clamping plate 5, pivoted to the casing 1, and carries three inwardly directed cone-shaped projections 5b which locate in recesses 21 in the guiding blade. The clamping plate is held by a cam lever 19, attached to the top of the casing by a link 20, so that the lever 19 in the downward position clamps the casing 1 to the guiding bar 3. The link may be screwed and lock nutted to take up wear in the cam lever 19. To remove the handle portion the lever 13 is swung out from the handle 4, the catches 11a, 11b engaging the end of the idler pulley axle are released and the axle withdrawn. The cam lever 19 is then raised, the clamping plate swung out and the handle portion removed from the guiding bar. The saw can then be withdrawn longitudinally through the cut and the saw reassembled in the reverse order. In another form the catches 11a, 11b are omitted and the axle retained by the clamping plate 24 which is of greater width and overlies an enlarged square portion on the axle.

Title: Means for the cathodic protection of ships and the like
Inventor: NOWAK WILHELM
IPC: C23F13/04
Filed: 1958-03-12
Abstract: 859,096. Preventing corrosion. VOLKSWERFT STRALSUND VEB. March 12, 1958, No. 7922/58. Class 123(1) In an impressed current cathodic protection system especially for ships' hulls, the protective current is automatically switched on when the potential between the anode and the hull falls to a preset minimum and is switched off when it rises to a preset maximum. The anode 1 which is of a material such as iron, lead alloy, carbon or platinum and a coppercopper sulphate measuring electrode 2 are mounted in a streamlined body 3 of synthetic plastic material mounted on the hull 4. A voltmeter 6 constantly measures the potential between the electrode 2 and the hull. If the potential falls the voltmeter pointer 5 contacts a terminal 7 and a circuit including a relay 8 and a battery 12 is closed. The relay closes a switch 9 and a flow of protective current is established, an ammeter 10 measuring the current then being applied through the anode 1. As the measured potential rises the pointer 5 eventually contacts a terminal 13 whereupon the relay 8 is again energised to open the switch 9 and stop the current flow. In a modification, a single electrode is used alternately as a measuring electrode and as a protective anode.

Abstract: 691,256. Retractable undercarriages. ROE & CO., Ltd., A. V. March 27, 1951. [April 3, 1950] No. 8256/50. Class 4. The fairing doors are opened and closed in correct sequence with the extension and retraction of an undercarriage by an arrangement comprising gear segments a, d on parts moving with the undercarriage and doors respectively, a locking plate j movable with each segment in operative connection with the doors, a cam plate b in operative connection or integral with each other segment, the cam plate b allowing a locking plunger m to enter a hole k in the locking plate under spring pressure or causing it to leave the hole when the segments are about to disengage or engage, respectively, the plunger and hole being so proportioned that the plunger can enter the hole before movement of the plate is completed in the direction corresponding with extension movement of the undercarriage. As shown the segment a is connected to the cross beam c of the undercarriage, while the segment d is mounted on a shaft e to which the door-operating mechanism is connected. The locking plunger m is tapered in order that it may enter the hole k in the locking plate before disengagement of the gear segments a, d is completed. In the fully retracted condition shown in Fig. 3, the plunger m is held clear of the hole k by the engagement with the cam b of a roller p on the spring-loaded lever n carrying the plunger. During the initial extension movement the segments a, d first rotate the shaft e to open the fairing doors, and after a predetermined angular movement of the undercarriage, as the segments are about to disengage, the cam b allows rotation of the lever n so that the plunger m commences to enter the hole k. Upon disengagement of the cam b from the roller p the loading springs n<SP>1</SP> effect complete engagement of the plunger m in the hole k, thus locking the plate j and shaft e and holding the doors in the opened position. The undercarriage is then free to complete its lowering movement while the doors are held open, as shown in Fig. 4. During retraction the doors are held open until the undercarriage approaches its retracted position, when the segments a, d re-engage and the operation of the mechanism is reversed to effect unlocking and closure of the doors.
