Abstract: 1,105,542. Measuring speed, viscosity or temperature. HONEYWELL Inc. March 9, 1965 [March 16, 1964], No.10052/65. Headings G1K and G1S. [Also in Division G3] Hydrodynamic apparatus for sensing angular velocity or fluid-viscosity comprising a housing 11 with a plane surface 12 having two orifices therein terminating passages 13, 15 equidistant from an axis 17 in the plane 12 and with a flange 18 whereby the housing 11 is mounted close to a body 25 rotating about an axis parallel to axis 17 with the plane 12 close to the periphery 26 whereby the passages 13, 15 sense the increased and decreased pressures which occur in ambient fluid ahead of and behind the tangent point 27 during rotation as a hydrodynamic pumping action is set up. The differential pressure may be measured or applied to actuate a fluid switch (see Division G3) for control purposes which may be retroactive e.g. to maintain a constant angular velocity in a turbo-jet engine. Elongated orifices, Fig. 4 (not shown) are needed to increase the flow to a fluid amplifier. Formulae are given showing the relationship between dimensions, viscosity, pressure and velocity. Because the viscosity and clearance 'h' depend upon temperature, the apparatus can be used to measure temperature if the speed and diameter R are held constant. When designing the apparatus for measuring speed or viscosity, the coefficients of expansion of the housing 11, and body 25 may be chosen to vary 'h' so as to compensate for the effect of temperature on viscosity. A clearance of 0À005 inches was found successful.

Title: Improvements in and relating to tool holders for planing, shaping, or the like machines
IPC: B23D13/00
Filed: 1952-04-29
Abstract: 714,455. Planing-machine details. WALDRICH, GES., H. A. April 29, 1952 [April 30, 1951], No. 10772/52. Class 83 (3). A tool clapper, slide &c. 1 in a planing &c. machine has mechanism for positively moving it into the operative position after each non- working, return stroke of the tool or work. An electric motor 11, Fig. 1, is mounted on the tool head 3 and energized by a dog on the machine table to lower the tool slide 1 until an inclined face 4<SP>1</SP> on the slide bears against a similar face 4 on the head. The motor is coupled to the slide through gearing 12, Fig. 2, a shaft 13, an irreversible worm-wheel drive 6, 6a, and a link 2<SP>1</SP> mounted eccentrically on the wheel 6a and connected by a pin 8 to a member having an inclined surface 51 which engages a similar surface 5 on the slide to clamp the faces 4, 41 together when the pin 2 nears its deadcentre position. The motor 11 continues to rotate the worm, which consequently moves relatively to the worm-wheel against the influence of a pressure device, such as springs 7, until it operates a limit device, such as a clutch for interrupting the drive or a switch 10 for stopping the motor, whereafter the influence of 'the compressed springs maintains the clamping pressure. A wedge 9, beneath a pad 9<SP>1</SP> through which the clamping pressure is transmitted by the end of the link 2<SP>1</SP>, can be adjusted to compensate for wear by a screw 9<SP>11</SP> or by a spring if the angle of the wedge is small enough for the wedge to be self-locking. At the end of a working stroke, a dog on the table energizes the motor to run in the opposite direction and raise the slide 1, a limit device, such as a switch associated with the tool-holder or the operating mechanism, stopping the motor when the slide has been raised. In a modification, Fig. 3, the inclined face 4 on the tool-clapper 1 is clamped against the head by a roller 2a slidable in a slot 2b in the clapper and mounted on a crank 2 rotated by the worm-wheel 6a. As in the first embodiment, the worm-shaft 13 operates the switch 10, Fig. 4, for stopping the motor 11 which drives the shaft 13 through gears 12, the shaft 13 co-operating with the switch through a lever 10b and a push-rod 10c. After rocking the clapper about its pivot la to the raised position, the motor 11 is stopped by a switch 19b which is operated by a dog 19 contacting a lever 19a. The dog 19 is mounted adjustably on a slide, Fig. 5 (not shown), driven through reduction gears from a rack which is operated by a pinion on one end of a shaft 21, the shaft being rotated by an arcuate rack 23 on the clapper which meshes with teeth on the other end of the shaft 21. A scale co-operates with a pointer on the slide to indicate the angular position of the clapper. The setting of the crank may be adjusted by a wedge.
