Abstract: 440,702. Combined sound-reproducing and kinematograph apparatus. RICO, R. P., Ibi, Alicante, Spain, May 10, 1935, No. 13742. [Class 40 (ii)] [See also Group XX] A combined toy kinematograph and sound-producing apparatus comprises a picture projector and a pneumatic device adapted to co-operate with apertures in a moving strip or film in order to produce musical sounds, said strip or film also carrying pictures adapted to be projected by said picture projector. As shown, a moving strip or film formed with two rows of pictures and a plurality of apertures as shown in Fig. 5 is unwound from a spool (not shown), mounted between supports 21, 22, Fig. 2, and wound up on to a second spool 20 by rotation of a handle 1, Fig. 1, the shaft 3 of which has an endless screw 2 meshing with a gear-wheel 24 on the spool 20. During the passage of the film from spool to spool, the musical accompaniment is produced by cooperation of the apertures in the film with apertures 19 fitted with reeds in a container 43 into which air is forced by bellows 5, Fig. 3, operated through levers 4, 28 and 29 from the shaft 3. The pictures on the film also pass between a light source 9 and a pair of stationary apertures 14<a>, 15a with which further apertures 14, 15 in a shutter 13 are adapted to co - operate alternately, the shutter being oscillated vertically, Fig. 2, by a plate 4a on the lever 4 operating the pivoted lever 12. The shutter also carries two prismatic lenses 26, 27, Fig. 3, adapted to bring the light rays into line with an objective 37. A slotted plate is provided which can be operated to lift the wheel 24 out of engagement with the endless screw 2 when the film is to be rewound. The air container 43 is provided with a movable wall and a regulating valve for preventing the pressure of air in said container from exceeding a predetermined value.

Title: Improvements in or relating to building and like units
Inventor: KRUSCHANDL EDWARD VICTOR
IPC: C04B28/00
Filed: 1961-04-19
Abstract: A building unit is formed by moulding a mixture of natural cellulosic fibres, powdered calcined bauxite, and a hydraulic cement at a pressure of 10,000-80,000 p.s.i. and allowing to set. The fibres are preferably of uniform length, e.g. 1/12 to 4 inches, and may be of coir or jute waste, cotton or rice stalks, wood shavings or bagasse. The fibres may be first treated with steam and then with an aqueous fire-proofing solution of calcium chloride, sodium silicate, magnesium sulphate, or an alum.  The bauxite may have a particle size of less than 200 BSS.  The hydraulic cement may be Portland, magnesite, blast furnace, or hydrophobic cement.  Calcined magnesite cement is preferably burnt at 1100-1300 DEG F. and ground to a particle size of at 200 BSS. The amount of bauxite present may be 5-100% based on the hydraulic cement.  An aqueous solution of calcium chloride, magnesium chloride, magnesium sulphate, sodium silicate, or an alum may be present as a setting accelerator.  Calcium nitrate, sulphate, or ligno sulphonate may also be present.  In the examples the proportion of fibres (based on fibres, bauxite, and cement) is in the range of ca 32-63%.

Abstract: 118,642. Kraft, H. P. June 26, 1917, [Convention date]. Butt joints with valves. -In a coupling for attaching an inflating pump to a tyre nipple, in which a swivelling nut screws on to the nipple, the end of which abuts against a packing-ring, the nut C has its internal threads formed upon a separate member I removably held in a recess so that it can be withdrawn when necessary to allow renewal &c. of the packing-ring F. Relative rotation of the parts I, C is prevented by giving the part I a hexagonal or other non-circular form and housing it in a corresponding recess. The member C is held in place by a screwed sleeve J, to which it may be rotatably secured as by flanging outwards the end M to prevent loss and facilitate removal together. The member J has slots J<3> to receive the edge of a coin for use as a screwdriver. A modification is described in which the members I, J are both housed within the member C. The invention is applicable to any form of connector, but is shown as applied to a connector B of the type described in Specification 102,970, in which a valve P carried by a plunger is normally held on a seat O, but is opened when a pressure gauge is applied to depress the plunger, the tyre valve also being opened thereby to put the gauge in communication with the tyre.

Abstract: The invention relates to aromatic hydroxy compounds of the formula <FORM:0935061/IV(a)/1> in which the two substituents in the benzene nucleus stand in the p- or m-position to one another and R1 and R2, which may be the same or different, are mono- or di-hydroxyphenyl, monohydroxyalkyl- or arylphenyl, monohydroxyhalophenyl or monohydroxynaphthyl radicals.  The compounds may be prepared by reacting more than 2 mols. of a phenol, a dihydroxybenzene, an alkyl-, aryl- or halo-phenol or a naphthol with m-or p-diisopropenylbenzene or with a benzene derivative substituted with two groups -C(CH3)2Y, the substituents standing in m-or p-position to one another and Y denoting a halogen atom or a hydroxy, alkoxy, aryloxy or acyloxy group.  The reaction of m-or p-diisopropenylbenzene with a phenolic compound, as defined above, is preferably effected in the presence of a strong acid catalyst, a number of which are specified.  When Y in the formula above is a hydroxy, alkoxy, aryloxy or acyloxy group the reaction is effected similarly.  When Y is a halogen atom the reaction may be effected at room temperature in the absence of a catalyst. Examples are given in which (1) phenol and p-diisopropenylbenzene yield a ,a ,a 1,a 1-tetramethyl-di-(p-hydroxyphenol) -p-xylene (product A); four methods of effecting the reaction are described, and the corresponding products from m-diisopropenylbenzene and from o-cresol are said to be similarly obtainable; (2) phenol and a ,a ,a 1,a 1-tetramethyl-p-xylene dichloride yield product A; (3) phenol and a ,a ,a 1,a 1-tetramethyl-a , a 1-dimethoxy-p-xylene yield product A; (4) phenol and a ,a ,a 1,a 1-tetramethyla , a 1-dihydroxym-xylene yield a ,a ,a 1,a 1- tetramethyldi- (p-hydroxyphenyl) -m-xylene. The products are useful as anti-oxidants.  a ,a ,a 1,a 1- Tetramethylp-xylene dichloride, used in Example 2, is obtained by chlorinating p-diisopropylbenzene under irradiation at about 15 DEG C.  a ,a ,a 1,a 1- Tetramethyla ,a 1- dimethoxyp xylene, used in Example 3, is prepared from a ,a ,a 1,a 1-tetramethyl-p-xylene dichloride and sodium hydroxide in methanol solution.  a ,a ,a 1,a 1- Tetramethyla ,a 1- dihydroxym xylene, used in Example 4, is obtainable by reducing m-diisopropylbenzene dihydroperoxide with sodium hydrosulphite.

In the manufacture of a rolled-type capacitor two metal, e.g. aluminium, foils 1, 2 which are displaced with respect to each other in the width direction are interleaved with strips 3, 4 of stretched or expanded polystyrene and are then wound together, the resultant roll being heated to a temperature of between 100 C. and 110 C. to cause the polystyrene to consolidate to a single mass within which the electrodes 1, 2 are embedded. By virtue of the initial stretched condition of the polystyrene, which is brought about during its manufacture, contraction occurs during heating, thus ensuring that the consolidation takes place. The strips are wound together on a mandrel 5 which is removed before the heating operation is carried out and replaced by a short polystyrene rod fitting wholly within the capacitor roll and two copper wires which protrude from the ends of the roll and are connected to copper strips attached to the electrodes 1, 2 as described in Specification 748,900.

So long as a solenoid 26 is not energized, a spring 24 pulls its armature 25 and thence the arm 7 so that the flexible periphery of a weight 10 is held against the stop 12. When the solenoid is energized e.g. by actuation of a vehicle ignition switch the armature 25 is pulled against the spring 24 into engagement with a pole piece 30 and dis-engages the arm 7. A weaker spring 36 then lifts the weight 10 from the stop 12 until an abutment portion 9 of the arm 7 engages a preselected abutment surface 56 of the member 37, Fig. 3. The selection in made by means of a knob 49 on a shaft 45 pinned to the hub 41 of the member 37 and the selected surface 56 is held in position by a leaf spring 52 urging a detent 55 into a corresponding groove 51. When the vehicle is running, vibrations caused by road shocks cause the arm 7 and a stylus arm 17 to oscillate so that a member 21 traces a band diagram on a chart 22 of width corresponding to the selected range of oscillation of the arm 7 whereby the measured width can be used to identify the vehicle driver during the particular time of operation.
