Title: Improvements in typewriter paper of deferred indelibility and method of preparing the same
IPC: D21H19/10
Filed: 1934-09-08
Abstract: 434,852. Typewriting paper. CALLAN, J. G., 24, Quincy Street, Cambridge, Massachusetts, U.S.A. Sept. 8, 1934, No. 25905. Convention date, Sept. 23, 1933. [Class 96] Paper 2 for typewriting use, has a surface coating 1 of uniform thickness of 1-2 tenths of a mil, following the irregularities of the paper surface and formed of material, e.g. casein, tanned glue, starch, &c., permeable to typewriter ink only after some time during which the typescript may readily be erased without using abrasive erasers, but after which the impression is relatively indelible. The coating is fragile enough to develop slight discontinuities on impact by the typewriter key. The coating is hardened with formaldehyde &c. and may contain sulphonated castor oil or soap, the latter ingredients may also occur in the typewriter ink. The paper may have had the usual rosin sizing at the beater, and the coating material may be applied cold, e.g. by a coating machine having a roller feed and rotary brushes. Initial drying is preferably effected at or below room temperature, e.g. the paper " floating " on a series of upwardly directed streams of air emerging from a blower-trunk of rectangular section. In an example, to make a coating composition, 1¢ lbs. of casein per gallon of water is soaked 1-2 hours, cooked, and cut with borax or ammonia, left 12 hours at room temperature, diluted with 20 gallons of water to 15 of solution, and 2 quarts of 50 per cent formaldehyde and colour and china clay are added.

Title: Improvements relating to lubrication systems
Inventor: KNIGHT FRANK
IPC: F16N25/04
Filed: 1961-07-18
Abstract: 939,078. Lubrication. LOXHAMS ENGINEERING WORKS Ltd. July 13, 1962 [July 18, 1961], No. 25937/61. Class 12 (3). A lubrication system has a distributer with a ported rotor in a ported stator and has a ratchet mechanism which rotates the rotor stepby-step in synchronism with the working cycle of the engine &c. being lubricated. An oil-feed pipe enters the stator and leads to an axial port in the rotor and a number of oil-delivery ports lead from the stator and register successively with a radial port in the rotor. The feedpipe has a check-valve therein. In an embodiment, a casing 1, of the distributer, is mounted on a support 2 and is secured thereto by screws 3. The casing 1 contains an impulse pump having a plunger 4, Fig. 3, in a liner 5, the plunger being reciprocated by a radial arm 6 on a shaft 7 which is mounted in bearings in walls of the casing 1. The shaft 7 carries an arm 8, Fig. 4, which is connected by a member 9 to an oscillating plate 10 on a spindle 11, which has a ratchet wheel 12 thereon engaged by a spring-pressed feed pawl 13 mounted on the plate 10. Return movements of the ratchet-wheel 12 are prevented by a spring-pressed pawl 14 carried by the casing 1. An arm 15, Fig. 2, is carried by the shaft 7 and has at one end thereof a roller 16 which engages a cam 17, the rotation of which displaces the arms 15, 6 and 8 to cause the plunger 4 to supply oil to an outlet pipe 19 and to trail the pawl 13 to the next tooth of the wheel 12. The arms are returned to their initial positions by a spring 18, connected to the arm 15 and the support 2, and the pawl 13 rotates the wheel 12 a distance equal to one tooth. The pipe 19 is connected to a radial port 26, Fig. 5, of a rotor 20, which is in a housing 21 secured to the casing 1. Oil passes from the port 26, via an annular space 27, through an axial port 30 and into a radial port 31, which registers with one of a series of delivery ports 32. Each port 32 communicates with a delivery conduit 33 leading, for example, to a quill, as described in Specification 939,077.

Title: Improvements in brakes for internal combustion engines and the like
IPC: F16D57/06
Filed: 1923-10-23
Abstract: 206,493. Bauer, W. S., (Assignee of Wright, P.). Nov. 2, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Automatic speed or power control; hydraulic transmission.-Comprises means for braking the rotating shafts of internal-combustion engines which may serve either to limit the speed of rotation or, in cases of emergency, to lock the shaft against rotation. The invention is intended for limiting the speed of motor-cars, trains, &c. The device comprises a pump located in a casing 1 fixed to the vehicle, the gears 2, 3 of which are adapted, when rotated by the shaft 4 to which the gear 3 is rigidly ,attached, to circulate liquid from an inlet 6 through the casing 1 to an outlet 5, whence it is returned through the chamber 11, port 14 and chamber 12 to the inlet. The outlet 5 normally registers with a port 8 in a spring- controlled valve 7, and the port 14 may be restricted by a screw-threaded member 16, the position of which may be adjusted by means of a handle 17. Normally the pump circulates liquid freely through the system, but when a certain speed is attained, dependent on the extent to which the port 14 is restricted, the circulation of liquid becomes checked, and it tends to accumulate in the casing 1 and the chamber 11, when the fluid friction tends to check the speed of rotation of the shaft 4. Further increase of speed results in the raising of the valve 7 by the pressure developed in the chamber 11, whereby the ports 5, 8 are thrown out of register and the pressure of liquid in the casing 1 increases rapidly and the fluid-friction decreases the speed of the shaft until the valve 7 drops into its normal position. The valve 7 may be connected through a bell-crank lever 33 with pull rods 38, 40, leading respectively to the valve 55 in the fuel-supply pipe 39, Fig. 7, and to the brake lever 41, so that the raising of the valve may partially cut off the fuel supply, and the driver may operate the valve to check the speed of the shaft, or lock it against rotation. Provision may also be made for electric or pneumatic control of the valve. To enable traffic authorities to limit the speed of motor-vehicles fitted with the device, the member 16 may be locked in position by means of a screw 21 engaging the handle 17 and provided with an arm 24, so that sealing-means may be attached to openings 25, 26 in the members 16, 24 respectively.
