Title: Improvements in or relating to step-by-step electric switch control apparatus
IPC: F16H63/14
Filed: 1961-04-14
Abstract: 950,755. Switches held. set and freed mechanically. REGIE NATIONALE DES USINES RENAULT. April 14, 1961 [April 22, 1960], No. 13521/61. Heading H2B. A manually operable step-by-step switch comprises two coaxial rings 3, 9, rotatable separately and urged by springs 4, 10, to a neutral position, ring 3 having spaced notches along its outer periphery, a neutral notch N being empty and the other notches (in the preferred embodiment) containing contacts 5 engageable by a spring latching member 7, which is also a contact member, slidable in the switch casing (not shown), a handle 15 operating a switch actuator member 11 pivoted to ring 9, actuator 11 having projections 38 for engaging said notches, movement of the handle unlatching member 7 from its notch and causing a projection 38 to engage a notch of ring 3 and step rings 3, 9 together round one notch until member 7 latches in the notch adjacent its initial notch, ring 9 returning to the neutral position when handle 15 is released. Conducting pins 22, 23, insulatingly fixed in ring 9, project through elongated apertures 34, 35 of actuator 11 to form alternative pivotal points for the actuator, which has a conducting bar 12 bearing upon both pins in the neutral position. When handle 15 is moved, the actuator pivots about one pin 23, say, and bar 12 engages a shoulder 43 on contact 7 to unlatch it before the rings are stepped round a notch with further movement of the handle, ring 9 being moved when the other pin 22 engages the edge of aperture 34 of the actuator. A spring 14 ensures the return of the handle 15 and actuator 11 to the neutral position. An indexing blade (not shown) attached to ring 3 acts as a position indicator, and operation of this blade upon failure of the actuator mechanism unlatches contact 7 in an emergency. The step-by-step mechanism is by-passed by pulling handle 15 radially outwardly to unlatch contact 7 from its notch, whereupon spring 4 returns ring 3 immediately to its neutral position. A resistance (not shown) is connected across pins 22, 23, so as to be short-circuited by bar 12 in the neutral position but included in the energizing circuit during the stepping operation (Fig. 14, not shown). The switch casing is in two halves and is mountable on the steering column of a vehicle, the switch controlling the gears of the vehicle (Figs. 1, 2, not shown).

Abstract: 806,024. Pneumatic jacks. BRITISH MESSIER, Ltd. May 2, 1957 [May 2, 1956], No. 13598/56. Class 8(2). [Also in Groups XXIX and XXXIII] A jack for an aircraft undercarriage (see Group XXXIII) comprises a cylinder 31 and a piston 34 forming a chamber pressurized to a desired value through an air valve 46. A disc 36 secured to the piston supports a ring of flexible tongues 37 ending in abutments 38 engageable with a shoulder 42b on a lock sleeve 42 fixed to the cylinder. A lock piston 39 also slides in cylinder 31 under the action of a spring 40, and has a portion engageable within the ring of tongues 37, to maintain the latter in engagement with lock sleeve 42. To unlock and retract the jack, fluid under pressure, is admitted through a port 45, to force back the lock piston 39 against spring 40 and release the tongues 37, whereupon the piston is free to move under the fluid pressure, compressing the air in the reservoir. To extend the jack, the pressure fluid is cut off from port 45. Spring 40 extends, and the air in the reservoir expands to return the piston 34. At the end of the stroke, the tongues 37 push back piston 39 until the abutments 38 engage the shoulder 42b whereupon spring 40 returns piston 39 to lock the jack.
Patent GB-895220-A (GB)
Title: A process of making refractory shells for casting metal
IPC: B22C1/16
Filed: 1960-04-19
Abstract: A refractory shell mould for casting metal articles is made by coating an expendable, e.g. wax, pattern at least twice with a slurry containing a silica binder and a refractory powder, applying a stucco of coarse refractory material to each slurry coating, and applying to each stucco coating a dry powdered alkaline binder material, thereafter removing the pattern from the shell and firing the shell. The dry alkaline binder, which acts as a low temperature binder, may, if desired, be applied by incorporating it in the stucco.  In a preferred embodiment, the pattern is precoated by dipping in a refractory slurry, drained, and then stuccoed with a sharp angular sand to provide a mechanical keying to the following shell coat.  The silica binder, which acts as a high temperature binder, contains a substantial proportion of a volatile medium and has a silica concentration of about 25%, such a composition being ethyl silicate 58,9%, methyl alcohol 33,9%, water 7,2% and hydrochloric acid 0,1%. This is mixed with equal parts by weight of silica flour (200 mesh) and silica sand (60 mesh), suitably 53 lbs. of silica to 10,000 c.c. of binder.  The precoated pattern is immersed in this slurry and after draining is sprinkled with a coarse refractory grit, e.g. calcined aluminium silicate, and then dusted with a dry, powdered alkali binder, e.g. sodium metaborate or tetra-borate.  The pattern is then allowed to dry for 2 or 3 minutes until gelation has taken place.  This cycle of operations is repeated until a shell of adequate strength has been built up.  In another embodiment, the shell strength is increased by the incorporation in the refractory slurry of a second high temperature binder, e.g. magnesium ammonium phosphate.  The elimination of the pattern and the firing of the shell preferably take place in one operation by heating to between 1500 and 2000 DEG F., commonly about 1800 DEG F.  The shell is then cooled to the desired casting temperature.

Abstract: 990,866. Gravity-separation apparatus; sandcones ; classifying granular materials. B. LEY. April 10, 1962 [April 19, 1961], No. 13746/62. Headings B1D and B2H. A mixture of sands, or sand and dirt, and water, is pumped through an inlet pipe 17 to a vertically-movable cone 3. Lighter sand or dirt flows out with the water at 21, 19. When a predetermined weight of heavier sand in the cone 3 is exceeded, the cone moves downwards, raising, as it does so, the inner ends of levers 5 from which it is suspended about fulcrums 6 by links 4. Segment-shaped plates 8 secured at the inner ends of the levers 5, and bearing under a stop 9 on a valve rod 10, thereupon raise the rod 10 to withdraw a valve cone 11 from a discharge opening at the lower end of the cone 3. Surplus water can be tapped off through a perforate pipe end 22 connected at 20 to a combined drain and water-feed system. The apparatus is mounted on a mobile stand 1. For sorting a mixture of sands in water according to grain sizes the mixture is fed into cone 3 as before. Then water is introduced at 20, 23 into the sand at a pressure which ensures that the large-grained sand remains in the cone, whilst smaller grains are discharged with water at 21, 19 (for further sorting in similar apparatus). For washing dirty sand, water is introduced at 20, 23 (after draining at 19, and 22, 20), and leaves with dirt at 19. Additional features are provided in Fig. 3 (not shown) for classifying according to grain size. The rod 10 is made hollow, and additional water can be fed down it to emerge through one or more of a number of circular discharge tubes arranged around it. A float with a horizontal baffle, and supporting a feed ring, may be secured adjustably around the upper end of the hollow rod.

Title: Method of and apparatus for making dental radiographs
IPC: G03B42/04
Filed: 1939-05-11
Abstract: 530,440. R÷ntgen-ray apparatus. WEAL, A. DE. May 11, 1939, No. 14045. Convention date, May 13, 1938. [Class 98 (i)] A dental radiograph is made by holding a film adjacent the inner face of a tooth and directin the X-rays along a path deviating from a path perpendicular to the plane bisecting the angle between the plane of the film and the long axis of the tooth, as indicated by the crown of the tooth, by the addition of an angle which increases in size as the long axis of the root deviates increasingly from the long axis of the crown of the tooth. The added angle may consist of a fixed angle of from 5 degrees to 12 degrees, and preferably of about 9 degrees, a variable angle increasing from 0 degrees to 10 degrees as the deflection of the film increases from 0 degrees to 60 degrees with respect to a plane perpendicular to the occlusal plane. The apparatus shown for indicating the direction of the rays comprises an elongated hollow frame formed of two channel-shaped members 10, 11 terminating in down-turned grip portions 10a, 11a. The film-holder comprises a bar 13 over which fits a tubular member 15 having an overhanging top portion 18 to receive the top edge of the film 17, the lower edge of the film fitting into a recess in the bar. A pivoted link 19 connects the film holder to the end of the frame, and the lower end of the holder is connected by a link 12 sliding in the hollow frame to the upper ends of finger members 29. The members 29 are connected by pivots 31 to arms 24 secured to a pointer 23 mounted on a shaft 25 carried by the frame. A spring 27 tends to turn the pointer towards the horizontal, and the film holder towards the vertical positions. A bite block 32 comprising surfaces 32b, 32c engaged respectively by the biting and outer surfaces of the tooth is removably held on the frame by means of spaced depending legs engaging in tubular sockets secured to the frame, to which is also secured a saddle member 35 to be engaged by the opposed teeth. In use, the finger members 10a, 10b and 29 are gripped by the operator, tilting the film holder backwardly to the limit of its movement, and the forward end of the apparatus is inserted in the mouth of the patient so that the tooth to be radiographed bears on the block 32. On release of the finger pieces the spring 27 causes the film holder to move clockwise until the film is as nearly as possible parallel to the tooth, and at the same time the pointer 23 moves to a position in which it indicates the correct direction of the rays. Suitable dimensions are given for the various parts so that the pointer may correctly indicate the desired direction.
