Title: Coin-ejecting mechanism
IPC: G06C25/00
Filed: 1958-10-13
Abstract: 849,018. Coin-delivery apparatus. NATIONAL CASH REGISTER CO. Oct. 13, 1958 [Nov. 22, 1957], No. 32548/58. Class 27 A coin-ejecting mechanism, particularly for a cash register, comprises several coin compartments 151 each provided with an ejector 153, a driving shaft 158 common to all the ejectors, a driving member 168 on the shaft for each ejector and coupling means 163 selectively operable according to the amount of change required to connect the required number of ejectors to the shaft 158. The ejector 153 is pivoted at 156 on a rocking arm 157 which is loosely pivoted on the shaft 158 and is spring-loaded into engagement with a stud 160 on an arm 161 also loose on the shaft 158. When the shaft 158 is rocked counterclockwise, the arm 168 pinned on the shaft releases the latch 163 and, provided the other end of the latch has also been released by the withdrawal of a stud 191 by the energization of a solenoid 131, a shoulder 197 on the latch is picked up by a shoulder 198 on the arm 168. The rotation of the latch 163 and arm 161 then allows the spring 148 to drive the ejector to the left and eject two coins. For rocking the shaft 158, it is connected by a crank and connecting rod to a first lever pivoted at 173 and having a slot in which works a stud 175 on a disc 176 loose on a motor-driven shaft 188. When a solenoid 184 is energized, a locking pawl 178 is withdrawn from the disc 176 and a clutch arm 182 is withdrawn from a clutch pawl 186 so that the latter engages a clutch member 177 and connects the disc to the shaft 188. A switch 261 controlling the time when the solenoids 131 can be selectively energized is either operated directly by the first pivoted lever or a second lever 265 pivoted at 173 is provided and is rocked by the stud 175, the amount of movement being controlled by notches 267 and 273 on a latch arm 268 moved by a stud 272 on the clutch arm 182. When the coins in a compartment are exhausted, a feeler 245 can move into the compartment and open a switch in the circuit of the motor driving the shaft 188. During the coinejecting operation, the feeler is withdrawn to relieve pressure on the coins by an arm 250 engaging a yoke 248 bearing on an extension of the feeler, the arm being raised by a member 252 which has a cam surface 254 engaging a stud on an arm secured to the shaft 158.

Filed: 1957-10-21
Abstract: 837,047. Fluid actuation of switches; thermal switches. HAUSSAUER, L. P. Sept. 19, 1958 [Oct. 21, 1957], No. 32785/57. Class 38 (5). A cut-out for an electric water-heater comprises a pressure-responsive diaphragm 21 secured round its periphery to a head portion 13 of a housing, the head portion being threaded into a water tank 16 so that the diaphragm is within the tank. A rectilinearly-moving stem 24 is secured to the diaphragm and carries an adjustable actuating screw 29 which bears on a plunger 33 of a snap-action switch having a contact 37 carried by a blade spring 35 cooperating with a bowed spring 40. If the heater is switched on with no water in the tank, the pressure in the tank forces the diaphragm downwards to open the contacts 37, 38, which remain open until reset by a button 41. The diaphragm is made of bimetallic material so that the switch is also opened upon predetermined water temperature being reached. The housing has a spigot portion 53 which is held in a recess 55 of the switch housing 32 by two set screws which engage a conical face 59 on the spigot (Fig. 2, not shown).

Abstract: 446,960. Making girders &c. KRUPP AKT.-GES., F., Essen, Germany. Nov. 27, 1935, No. 32920. Convention date, Nov. 30, 1934. [Classes 83 (ii) and 83 (iv)] Uniting by fusion.-A welded girder consists of a rolled section having a tapered rib 3 welded at 8 to another part section such as a web plate 7, the taper being such that by slight reduction of the height of the rib, it may be welded to a part of different thickness. Thus the rib may first be shortened as by planing at 9 so that its thickness is equal to that of a thicker web plate 10. The rib also merges into the flange 1 of the T-section shown in gradual curves 2 and the gradual transition from web to flange avoids concentrated stresses. The free end may be bevelled at 5 and the end of the web plate squared off at 6, or the ends may be gable-shaped to effect an X-weld. Angle, U-, I-, and Z-sections may also have their legs similarly tapered. A stanchion or column may be made by welding to each of the four flanges of a broad-flanged section a T-shaped section of the kind shown in the drawing. Girders may also be made by welding angle, U- and Z-sections to part sections having ribs tapered as shown.

Title: Improvements in or relating to soldering of metals
IPC: B23K35/36
Filed: 1952-12-31
Abstract: Pyrazoline hydrohalides for use in solder fluxes (see Group VI) are prepared by reacting an aldehyde or ketone with a hydrazine hydrohalide or with a hydrazine and a hydrogen halide.  The carbonyl compound may be reacted with the hydrazine, used for example in the anhydrous state or as an aqueous solution of the hydrate, and thereafter with the hydrogen halide in aqueous or gaseous form.  The carbonyl compound may be reacted with the hydrazine hydrohalide by admixture at ordinary temperatures or with application of controlled heat.  An inert solvent is used when the reactants are solid or viscous.  The products are recovered by crystallization and may be recrystallized, e.g. from methanol.  Examples describe the preparation of the hydrochloride and hydrobromide of 3,5,5-trimethyl pyrazoline from acetone and the appropriate hydrohalide of hydrazine and of a pyrazoline hydrochloride from methyl ethyl ketone and hydrazine hydrochloride.  Other reactants mentioned are di-acetone alcohol, di-ethyl ketone, methyl vinyl ketone, mesityl oxide, methyl phenyl ketone, acetaldehyde, propionaldehyde, acrolein and crotonaldehyde and dimethyl hydrazine, phenyl hydrazine and hydroxyethyl hydrazine and their hydrohalides including the hydrofluorides.ALSO:A solder flux comprises a solution of a pyrazoline hydrohalide obtainable by the reaction of an aldehyde or ketone with a hydrazine hydrohalide or with a hydrazine and a hydrohalide (see Group IV(b)).  The fluxes are particularly applicable to the soldering of a metal whose oxide can be reduced by the hydrazine e.g. copper, brass and aluminium and its alloys including the soldering of aluminium and its alloys with copper or brass using cadmium- or tin-zinc solders.  The preferred fluxes are aqueous solutions containing for example 2-50 per cent by weight of the pyrazoline hydrohalide.  However, an alcohol such as methanol or acetone may be used as the solvent.  The fluxes may contain additional materials such as wetting agents and, as an extender, ammonium chloride.  Specified fluxes are aqueous solutions of 3, 5, 5 - trimethyl pyrazoline hydrochloride or the corresponding hydrobromide, obtained by reaction of acetone with the appropriate hydrohalide of hydrazine and the pyrazoline compound prepared from methyl ethyl ketone and hydrazine hydrochloride and examples illustrate their spread action on aluminium.  Other starting materials mentioned are di-acetone alcohol, di-ethyl ketone, methyl vinyl ketone, mesityl oxide, methyl phenyl ketone, acetaldehyde, propionaldehyde, acrolein and crotonaldehyde and dimethyl hydrazine, phenyl hydrazine, hydroxy ethyl hydrazine and their hydrohalides including the hydro fluorides.

[Also in Group XL (a)] A colour television tube is provided with two beams, one beam 25, Fig. 4, having a width traverse to the phosphors equal to the width of one phosphor line, and the other beam 26 having a width transverse to the phosphors of all three phosphor lines. The beams may be derived from a single gun 12, 14, Fig. 6, the luminance signal 54 being used to control tube brightness and the beam being split by plates 15, 16 in accordance with the ratio of chrominance amplitude to luminance amplitude to give saturation control.
