Abstract: 1,029,377. Plant for the continuous production of building elements. L. FOULQUIER. July 15, 1964 [June 17, 1964], No. 29144/64. Heading B5A. A plant for the continuous production of building elements comprises a number of stations around a closed circuit, mould carriers 24 transversing the circuit from a casting station 21 to a component removal station 17 where each carrier is tipped sideways and the element is held and removed by a conveyer or transporter 27. The circuit comprises production tracks 2-4 and further tracks 5-10 where the concrete is allowed to set, the mould carriers 24 being transferred from tracks 2-4 to tracks 5-10 by a carriage 13 and are returned to one of tracks 2-4 by a further carriage 14. Each mould, fixed or replaceable on a carrier 24, is loaded with concrete at station 21, passes various finishing stations at 22 and is brought back to a production track as above mentioned to enter a station 16, where the mould is dismantled to allow the formed element to be subsequently removed at station 17 by transporter 27. Cleaning takes place at station 18, reassembly of the mould at 19 and addition of accessories, such as facings, at 20. The mould carriers 24 are moved on tracks 2-10 by devices 15 which comprise cable driven trolleys 52 which run beneath carriers 24 and couple therewith by means of fingers 69 which engage stops 47, Figs. 5, 6 (not shown). The mould carriers are transferred to or from and positioned on carriages 13, 14 by endless chains 42, Fig. 3 (not shown) mounted on the latter, the chains carrying lugs 46 which cooperate with the stops 47 when the carriers have been brought adjacent either pits 11, 12 or the appropriate track. At station 17 a tipper is provided, Fig. 7 (not shown), wherein the carrier 1 is locked by a device 26 and a supporting frame 73, 74, 76 is rotated on roller 78, the building element being simultaneously retained by the transporter 27.

Title: Improvements in or relating to slide projectors
Inventor: SZYMBER OLEG
IPC: G03B23/06
Filed: 1970-06-16
Abstract: 1,274,981. Control Of D.C. motors. G.A.F. CORP. 16 June, 1970 [17 June, 1969], No. 29207/70. Heading H2J. [Also in Divisions G2-G3 and H1] In a slide projector 10 having a rotary slide tray 14, a selector device controls the reversible motor 24 which rotates the tray to bring a selected slide to the projection position (see Divisions G2-G3). Tray 14 is keyed to a cap 35 which is rotated by motor 24 and which houses "units" and "tens" spring fingers such as 42a, 41a wiping over resistors 95a-95i, and 96a- 96i, to switch in an increasing resistance which is compared with a resistance set by "units" and "tens" wheels 110, 130 of a remote control unit 100 via terminals 165, 166, 172, 218. Motor 24 is energized until these resistances balance. Transistor 181 (NPN) and relay 182 control motor 24, while transistor 183 (PNP) and relay 184 operate to reverse the motor to achieve "short-way home operation". When "units" selector wheel 110 is moved to a lower units number, contact 145 moves counterclockwise to decrease "units" resistance U R  and a negative pulse passes through diode 217 to switch on transistor 183 and so energize relay 184 to reverse motor 24. Conversely, movement of wheel 110 to a higher "units" number causes forward rotation of the motor. Rotation of "tens" selector wheel 130 also rotates contact 150, Fig. 12, so that for clockwise rotation, a fixed resistor 222 is added to U 2  to give a value greater than U in the projection. Transistor 183 is thereby switched off to give forward rotation of the motor and tray. Anticlockwise rotation of wheel 130 shunts U R  by the value of fixed resistor 223 to give a combined resistance less than U. Transistor 183 now operates to reverse the motor. Resistors 222, 223 and contact 150 thus provide an over-riding directional control of motor rotation during the 0-180 and 180-360 degrees tray positions. Control transistor 181 is switched off to stop motor 24 only when U = U R  and T = T R , ambiguous balances being eliminated by diodes 190, 190a. In the stop position of relay 182 the motor is short circuited to provide dynamic braking.

Filed: 1932-10-19
Abstract: 408,699. Cleaning eggs. MIDWINTER, W., Ridley Cottage, Greenham Common, Newbury, Berkshire. Oct. 19, 1932, No. 29275. [Class 28 (ii).] An egg-cleaning apparatus comprises a rotary roller brush and a guide extending substantially parallel to the axis of the brush, the co-operating surfaces of the brush and the guide being so formed that, as the brush is rotated, the eggs are turned to present different parts of their surfaces to the brush and are simultaneously fed along the guide through the machine. As shown, the guide is formed by two other rotary brushes, and the longitudinal feeding is effected by a helical formation of the bristles. The brushes have end sprockets and a chain running over the sprockets connects the brushes together, so that when one is revolved by a handle, the others rotate in the same direction. The brushes are arranged in a trough 10 containing cleansing liquid, preferably warm soapy water, and are supported midway along their lengths by plate 23 which is cut away at 24 to permit the passage of the eggs. The eggs are inserted between the brushes through an aperture at one end of the top of the casing and are discharged on to a shoot, slightly inclined upwardly, at the other end of the casing. If desired, a spring stop may be provided for deflecting the eggs at some point in their travel, to present the ends of the eggs to the brushes, but generally it is found the pressure of adjacent eggs effects sufficient canting.

Title: Improvements relating to the soft soldering of aluminium
IPC: B23K35/36
Filed: 1936-11-02
Abstract: In soft soldering aluminium a soldering agent consisting of or containing the hydrohalic acid salt of a hydrogen-rich amine base is directly applied to the surfaces to be united.  Hydrogen-rich amine bases are defined as primary, secondary, and tertiary aliphatic amines, completely hydrogenated aromatic amines, completely hydrogenated heterocyclic amino-compounds containing not more than two nitrogen atoms in the molecule, mixed aliphatic-aromatic secondary and tertiary amines containing an aromatic and one or two aliphatic radicals, and mixed aliphatic-hydroaromatic amines with one or two hydro-aromatic and one or two aliphatic radicals.  Numerous examples of suitable salts are given.  Mixtures of various halide salts, e.g. hydrochlorides with hydrobromides or hydrofluorides, may be used, and the fluxes may be used in powder or paste form and may be mixed with plasticizers such as petroleum jelly, paraffin oil, oil of turpentine &c.  The powder or paste may be mixed with granules or powder of the solder metal, may be combined with the solder metal to form pellets, or may be used as filling for a hollow wire of the solder.  The solder may be, for example, tin, an alloy of 60 per cent of tin and 40 per cent of zinc, or an alloy of 40 per cent of tin, 40 per cent of zinc, and 20 per cent of cadmium.  A soldering paste may, for example, be formed of a mixture of dust of the alloy of tin, zinc, and cadmium, with 22 per cent of trimethylamine hydrochloride, and 6-8 per cent of petroleum jelly.  The hydrohalic acid salts may be combined with stannic halides to form complex salts, e.g. [(CH3)3NH]2SnCl6 or [(C2H5)3NH]2 SnBr2F4 which, when dissociated, do not attack any zinc present in the solder. These complex compounds may be used as complete soldering agents, the combined tin acting as soldering metal, but additional metal is preferably employed.
