Title: A flexible abrasive disc and method of manufacture thereof
IPC: B24D13/14
Filed: 1964-06-04
Abstract: A flexible abrasive disc comprises a supporting disc (1, Figs 1 and 5) of flexible material in laminar form, and a thickness of abrasive material made up by the superposition of several alternate layers of an abrasive material (5) and and adhesive material (4) in direct contact with one another.  The supporting disc may be of vulcanized fibre and has its surface knurled or punched to provide depressions (2) which may extend through the disc to form holes.  The surface may also be sandblasted and formed with larger holes (3), which during rotation of the disc, render the disc partially transparent to enable an operator to view the surface of a workpiece being abraded.  The surface is then covered with alternate layers of adhesive (4, 40, 41, 411), such as liquid synthetic resin, an abrasive (5, 5 DEG , 51, 511), the final layer being subjected to slight impression to form grooves (6, Fig. 3).  The disc is then placed in a furnace for drying and polymerizing of the adhesive. In apparatus for making the flexible abrasive disc, supporting discs (1, Fig. 7) are placed on supports (9) carried by a conveyer belt (7) guided over rolls (8). Each disc passes under a nozzle (10) which sprays adhesive on the disc, excess adhesive falling into a container (11), and a device (12) for spraying abrasive, the abrasive falling into a container (13).  At the end of the upper run of the conveyer, the discs are inverted to travel along the lower run of the conveyer, excess abrasive from the discs falling into a container (14).  The discs are carried repeatedly under the nozzle (10) and device (12) until the desired number of layers of adhesive and abrasive have been deposited on the supporting discs.  A rack or pawl arrangement may be provided to slowly rotate the discs as they travel along the upper run of the conveyer.

Title: Upgrading of calcareous rock phosphate
Inventor: BEN-ARI CAMELA
IPC: C05B11/02
Filed: 1960-07-01
Abstract: Calcareous rock phosphate is upgraded by calcining the rock, wet-slaking the calcined mass, separating the so-formed supernatant suspension of calcium hydroxide and phosphate from the main phosphate sediment, contacting the mixture of calcium hydroxide and phosphate thus separated with aqueous ammonium chloride, and separating the aqueous solution of calcium chloride and ammonia thereby formed from the residual phosphate, e.g. by decantation or filtration.  The slaking operation is preferably effected at the boil.  The suspension of calcium hydroxide and phosphate is preferably concentrated to a solid:liquid ratio (weight/weight) of 1:4 to 1:5 prior to the addition of ammonium chloride.  Solid ammonium chloride may be introduced into the suspension having such a solid-liquid ratio in order to dissolve therein, or the mixture of calcium hydroxide and phosphate may be recovered from the suspension and then introduced into an aqueous ammonium chloride solution.  The ammonium chloride used is preferably the stoichiometric equivalent of the calcium hydroxide. Ammonia may be recovered from the aqueous solution of ammonium hydroxide and calcium chloride by distillation and may be reconverted to ammonium chloride by introduction into an aqueous saturated sodium chloride solution which is then saturated with CO2 to precipitate sodium bicarbonate which may be separated to leave an effluent containing ammonium chloride.  Specification 887,000 is referred to.

The signals from the accelerometers 10 are integrated, squared and summed to give the square of the instantaneous linear velocity V in circuit 6. The outputs of the gyros 12 are squared and summed to give the square of the instantaneous angular velocity #. In a further circuit 38 signals from the accelerometers and gyros are multiplied in three pairs, the products summed and the sum squared to give by an identity shown in the specification (V. #)<SP>2</SP>. With the switches 40, 41 in the positions shown, the V<SP>2</SP> signal from circuit 36 goes in turn to a square root circuit 58, a reciprocal circuit 59 and a multiplier 60 where the signal is multiplied by a reference signal from 61 representing the design critical linear acceleration. It is shown that the ouput of multiplier 60 represents the instantaneous critical angular acceleration. The V<SP>2</SP> signal is also fed from circuit 36 to a reciprocal circuit 62, thence to a multiplier 63 for multiplication by (V.#)<SP>2</SP>, a subtractor 64 for subtraction of #<SP>2</SP> from circuit 37, the difference being fed to a square root circuit 65 the output of which is shown to represent the instantaneous measured angular velocity. With the switches 40, 41 reversed the outputs will relate to linear acceleration. The oritical acceleration signal is used to feed a sine arid cosine generator which causes one beam of an oscillo - scope to follow a circle of radius representing the magnitude of the signal while the measured value is displayed as a radial line within the circle, Fig. 5 (not shown).

Title: Automatic choke valve apparatus for an internal combustion engine
IPC: F02D41/06
Filed: 1975-06-03
Abstract: 1483175 Automatic chokes for IC engines HONDA GIKEN KOGYO KK 3 June 1975 23995/75 Heading F1H In order that a throttle 15 of an automatic choke assembly may be held open to a.greater extent at lower engine temperatures when starting, there is provided a fast idle cam 18 with an extra cam surface 18b brought into operation at low temperatures by a link 21, 22, 23 operated by a reversible pulse motor 5 which link can operate independently of a choke 2. The choke 2 is also operated by the reversible pulse motor 5 by means of a coupling which is resilient in respect of one direction of rotation of the pulse motor 5. Before starting the choke 2 is fully open and upon switching on the ignition circuit, a control means 4 rotates the motor anticlockwise so that a pawl 20 entrains link 21 to rotate the fast idle cam 18 to bring cam surface 18a beneath the throttle cam follower 17a. The torque from motor 5 is transmitted through a spring from a shaft 6 to a shaft 3 to close the choke 2. If the engine is very cold then the motor 5 rotates further anti-clockwise to bring the cam surface 18b beneath the follower 17a thus opening the throttle 15 further; the further rotation of shaft 6 being taken up by winding up the spring 7 since the choke 2 remains closed. Upon operating the starter, the motor 5 rotates clockwise so that pawl 9 engages pawl 8, thus rotating shaft 3 clockwise and opening the choke 2 to a part-open position which is maintained until the engine fires. Thereafter the choke 2 is  opened automatically by clockwise rotation of the motor 5 at a rate controlled by the control means 4 until it is fully open when the engine is warm. To ensure proportionality of throttle and choke openings as the throttle is opened by anti-clockwise motion, a projection 25 on a cam follower lever 17 bears against the cam 18 to rotate it clockwise, moving a link 26, with a lost motion slot 27, upwardly, thus lifting a link 14 and opening the choke 2.
