Title: Furnace mechanism for heating bolts, rivets and the like
IPC: B21J17/00
Filed: 1920-07-05
Abstract: 146,877. Twer, A. Aug. 20, 1918, [Convention date]. Rivet-heating furnaces.-In a furnace of the kind in which holders 8 for a number of rivets &c. 4 are continuously moved through a heating-chamber, the holders are guided in endless grooves 9, and are independent of one another, so that when the holders fall quickly along the semi - circular connecting-portion 10 between the upper and lower horizontal grooves at the discharge end of the furnace, the rivets are ejected into a receiver 30. The holders are moved by a pivoted catch 14, which engages projections 12 on their undersides, and is reciprocated by the action of a cam-operated lever 18 and a weight 20. The whole apparatus may be mounted on a carriage, so that it can be positioned in the furnace as desired or withdrawn bodily.

Title: Dual push button safety control system for machines
IPC: H02P1/02
Filed: 1956-06-19
Abstract: 795,996. Machinery safety devices. DICTAPHONE CORPORATION. June L9, 1956 [June 24, 1955], No. 18929/56. Class 80 (4). A two-handed safety operating device for a machine 6 comprises dual push-button switches 2, 4 which have to be closed simultaneously, or substantially so, to actuate a main contactor or relay 22 to initiate the operation of the machine. A time delay relay 21 which is set in operation when either of switches 2, 4 is actuated controls a switch 32 in series with the switches 2, 4 across the power lines 18, 20 so that whilst normally closed it opens after a short delay, governed by the discharge of a condenser 44 through a resistance 40 and the solenoid 42, to break the circuit of the relay 22. Thus if one switch 2 or 4 is operated first the switch 32 may operate before the other is subsequently operated to prevent relay 22 actuating. If both switches are operated together relay 22 will be actuated, before the time delay switch 32 is opened, to start the machine. In a modified arrangement a second time delay relay is provided to ensure that sufficient time is allowed for the main contactor or relay 22 to function after both switches 2 and 4 are closed. ______

Filed: 1973-04-19
Abstract: 1381466 Frictional detents ROBERT BOSCH GmbH 19 April 1973 [21 April 1972] 18932/73 Heading F2E A blower used for vehicle air conditioning and having an impeller connected to the shaft 2 of a motor (e.g. an electric motor) desirable in one direction of rotation incorporates a blocking device in the form of a spring 3 which prevents rotation of the shaft 2 against the direction of rotation of the motor as caused by air pressure from the ventilation. As shown, a conical spiral spring 3 has several windings which embrace the shaft 2-one end 5 of the spring 3 is suspended from a hook 4 cut out on a bearing cover 1 of the motor. The diameter of the spring 3 becomes smaller as the free end 6 is approached with the smallest diameter corresponding approximately to the diameter 0 of the shaft 2. With normal rotation of the shaft 2 by the motor the diameter of the windings nearer end 6 increases to reduce frictional losses (Fig. 1, not shown). When the impeller is moved in the reverse direction (arrow P in Fig. 2) owing to air pressure in the ventilation, the spring 3 is tightened around shaft 2 to bring it to a standstill. A cylindrical spiral spring may alternatively be used, and the spring 3 could be mounted inside the motor housing.

Title: Improvements in and relating to secret carrier wave signalling systems
IPC: H04K1/02
Filed: 1943-11-25
Abstract: 582,798. Frequency modulation. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Nov. 25, 1943, No. 19732. [Class 40 (v)] In a frequency-modulated radio signalling system, secrecy is effected by imposing on the carrier a frequency modulation by a distorting signal before it is frequency-modulated by the desired signal. The distorting signal may be a selected combination of a fundamental and its harmonics, and is removed at the receiver by a similar combination synchronized with that at the transmitter. As shown, the carrier oscillator 3 is first frequency-modulated at 5 by a distorting signal arising from an oscillator 11 and harmonics thereof generated at 12. A suitable combination is selected by plugs 30-32 and applied to modulator 5 through an amplifier 13. The distorted output from 5 passes through an amplifier 6 to a second frequency modulator 7 on which the desired signal is imposed through an amplifier 14. The F.M. carrier is further amplified at 8 and is then amplitude-modulated at 9 by the oscillator 11, the output passing to the aerial 4 through a power amplifier 10. At the receiver the aerial 33 feeds a normal superheterodyne converter 35, 36 and the I.F. output is divided into two channels 38, 39. The former responds to amplitude modulation and includes a rectifier 40 and filter 41 which synchronizes the harmonic generator 42 with that at the transmitter. The other channel 39 includes a heterodyne converter 52 for mixing with oscillations from a source 54 which is frequencymodulated at 53 by the same combination of fundamental and harmonics as was selected at the transmitter. The difference frequency output from the converter 52 is thus free of the distortion signal, amd is passed through the normal F.M. signal detector comprising limiter 55 discriminator 56, amplifier 57 and loud speaker 58. When no signals are present, the distortion signal is cut off at the amplifier 13 by a prohibitive bias which is removed by the device 15 as soon as signals start. Discovery of the distortion signal during non-signalling intervals is thus rendered more difficult. In a further system (Fig. 2, not shown), the desired signal before application to 7 is mixed with an oscillation of about 10 kc. which has a wide frequency deviation imposed on it by a selected combination of harmonics from the source 11, 12.

Title: Improvements in the recovery of high molecular weight carboxylic acids or their salts
IPC: C07C51/48
Filed: 1937-07-19
Abstract: In a process of recovering high-molecular fatty acids, or their soaps, in a pure form from crude mixtures by saponification and extraction of the unsaponifiable constituents, the latter are extracted with a mixture of a fat solvent and a monohydric alcohol, ether, ester, or ketone, all of which contain 3 to 6 carbon atoms. The purified soap is then treated with mineral acid to liberate the fatty acids.  Fat solvents specified are, benzine, benzene, toluene, xylene, carbon tetrachloride, trichlorethylene, chlobenzene, carbon disulphide, or di-isobutyl ether.  Added solvents specified are, propyl, isopropyl, butyl, amyl, or high alcohol; acetone, methyl ethyl ketone; ethyl acetate or diethyl ether.  The crude fatty acid-containing materials may be the oxidation products of paraffin or montan wax, oils, or of hydrogenation products of coal and tar; saponification products of waxes such as beeswax, carnauba or montan wax, sperm oil, or of wool grease.  The extraction is preferably effected at 30 to 80 DEG  C., and at atmospheric pressure, but elevated pressures may be used, using countercurrent flow in an extraction column containing Raschig rings.  With crude products containing a large amount of unsaponifiable constituents, a preliminary extraction with the low molecular alcohols, ethers, esters, or ketones, is preferably effected before the major step. The formation of emulsions is prevented by adding small amounts of methyl or ethyl alcohol.  In an example, a crude saponified mixture obtained from the oxidation products of paraffin wax is dissolved in water and extracted with a mixture of trichlorethylene or benzine and isobutyl alcohol or methyl ethyl ketone at 50 DEG  C.  The purified soap solution is then treated with a restricted amount of dilute sulphuric acid and the solution is concentrated, whereby the solvents are recovered.  A further amount of sulphuric acid is added and the liberated fatty acids are removed, washed and dried.
