Title: Improvements in or relating to hydraulic shock absorbers
IPC: F16F9/32
Filed: 1931-02-09
Abstract: 368,940. Hydraulic shock - absorbers. HOUDAILLE, M. and ETABLISSEMENTS M. HOUDAILLE, 50, Rue Raspail, Levallois-Perret, Seine, France. Feb. 9, 1931, No. 4060. [Class 108 (iii).] In hydraulic shockabsorbers having an air leak orifice from the top of a pressure chamber into a reservoir, the opening is larger than a capilliary opening, is not provided with a valve, and is submerged on the side towards the reservoir. Filtering material may be inserted in the passage leading to the orifice. In the construction shown in Figs. 1 and 2, an oscillating shaft 22a carries an external operating lever 25a and two internal vanes 20a, 21a movable in a cylindrical casing 12a having two vertical partitions 15a, 16a. The pressure chambers are separated from the reservoir 17a by a partition 13a which also carries the bearing for the shaft 22a. The two chambers into which the casing is divided by the vertical partitions 15a, 16a are provided with one-way replenishing valves 18a at the lower ends. The upper end of each pressure chamber communicates with a reservoir through a plug 35a having a leak orifice 33a which is larger than a capilliary opening and communicates on one side with a small tank 36a closed by a disc 38a. Any liquid leaking from the pressure chamber through the opening 33a fills up the small tank 36a until surplus liquid escapes into the main reservoir 17a through a small opening 39a in the top of the disc 38a. Leakage of liquid from one side to the other of the vanes takes place through radial passages 28a in the shaft, the flow being regulated by a valve 30a which may be screwed in or out by a short lever 9a. A filter 40, Fig. 6, may be interposed between the plug 41 and the pressure chamber. The restricted passage in the plug may be helical, as shown in Fig. 12, the passage being formed by flattening the tops of the threads of a screw plug 41. The ends of the plugs may be slotted or otherwise shaped to facilitate flow of liquid between the orifice and the filtering medium. In a modification shown in Fig. 13, the grooved plugs 146 are submerged by liquid contained in small reservoirs 144 which are supplied with leakage liquid collected by a groove 143 in the bearing of the operating shaft. The adjusting spindle 29 is guided centrally by a collar 140. In the further modification shown in Fig. 18, the packing joint for the operating shaft 23 is formed by a flexible packing ring 250 retained between conical surfaces on a ring 244 and in the end of the cap 238 which is screwed on to the body of the apparatus.

Title: Improvements in electronic ignition devices for internal combustion engines
IPC: F02P3/055
Filed: 1958-02-10
Abstract: 833,836. Ignition systems. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Feb. 10, 1958 [Feb. 28, 1957], No. 4317/58. Class 7(4) [Also in Group XXXV] A transistor 1, 2, 3 is associated with a voltage booster transformer 7, 9 the primary winding 7 being connected to an output circuit of the transister and the secondary winding 9 being connected (lead D) to a conventional ignition distributer (not shown). The transister may be a germanium P N P junction transister or a silicon transistor. As shown a bridge comprising two resistances 10, 11 connected in series between the poles of the battery 4 enables a suitable biasing potential difference to be maintained between the base and emitter of the transistor. A contact breaker 12 is arranged for periodically shorting the resistance 11. A polarizing winding 13 is connected in series with a coil 14 across the poles of the battery 4. The current through the transistor discontinues as soon as the switch 12 closes and a voltage surge occurs in the winding 7 and in the associated secondary winding 9 causing an ignition spark to occur. The induced voltage is much higher than it would be in the absence of the polarizing winding 13. The function of the coil 14, the self inductance of which is high with respect to that of the winding 13 is to maintain substantially constant the polarizing direct current flowing in the latter winding. The core 8 is a ferrite core forming a closed magnetic circuit. The winding 13 is preferably on an arm of the core which is opposite to the windings 7, 9. The pulse duration is shorter than in conventional ignition systems. It is stated that the transistor could be made conductive by means of pulses provided for instance by a photo-diode periodically lighted through a perforated disc driven by the engine. In this case no circuit breaking device would have to be used. To safeguard the transistor a small neon lamp 15 may be employed but in many cases this lamp may be dispensed with. An additional contact breaker could be inserted in series with the resistance 10. Should the negative pole of the battery be earthed the contact breaker 12 would have to be in series with the resistance 10. Circuit component particulars are quoted.

Filed: 1960-02-08
Abstract: 904,409. Control of D.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 24, 1961 [Feb. 8, 1960], No. 4396/60. Class 38 (3). [Also in Group XXXV] The control circuit for a D.C. motor 1 described in Specification 693,899 is modified in that the control voltage for winding 10 now includes an element derived from a transformer 2 proportional to the rate of change of the voltage on field 4 of generator 3, and potentiometer 17 is now connected across the exciter field 6 instead of the generator field 4. Hence, the control voltage, which reduces the forcing of generator 3 and therefore the acceleration of motor 1, now comprises the sum of voltages proportional to the load current of the motor 1, the voltage on exciter field 6 and the rate of change of voltage on generator field 4, which sum is matched against a reference voltage from a potentiometer 12. It is stated that greater stability of the system results. The amplidyne 7 may be replaced by a magnetic or electronic amplifier and this device may be connected directly with generator field 4, the exciter 5, 6 being omitted.

Title: Improvements in or relating to transistor flip-flop circuits
IPC: H03K3/286
Filed: 1955-02-15
Abstract: 778,152. Transistor one and two stable state and gating. circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 15. 1955 [Feb. 18, 1954], No. 4499/55. Class 40(6) In a circuit comprising two transistors 1, 2 and resistors 3, 4 each resistor is common to the collector circuit of one transistor and to the base circuit of the other and in at least one stable state the emitterbase paths of the two transistors are conducting, one of the transistors being traversed by a collector current so high that owing to the drop of the collector voltage the collector-base current amplification factor drops below unity. The emitters of the transistors are connected to one pole of the supply and base resistors 5, 6 are connected to the transistors 1, 2. In one stable state the transistor 2 passes heavy current so that the working point is at a, Fig. 2 the voltage drop across resistor 3 together with that across resistor 5 due to the base current of transistor 1, biasing transistor 1 to the point b. Input signals applied at terminal 7 to the base of transistor 1 are amplified using the load line R and appear at terminal 9. The circuit may be switched from one stable state to the other by signals applied at terminals 7 or 8. Resistor 10 may be the internal impedance of a switching source. By increasing the value of the resistor 5 and decreasing the resistor 4 the circuit may be made mono-stable. A pulse applied at terminal 7 triggers transistor 1 to point a and transistor 2 to point b. Due to the choice of component values the circuit is only maintained in this state until the: input capacitor has charged sufficiently when the circuit reverts to its normal state.

Filed: 1965-02-03
Abstract: A method of storing harvested bananas for a storage period during which they consume oxygen and give off unsaturated hydrocarbon gases including ethylene having a ripening and destructive effect on the bananas during storage, comprises: subjecting the bananas to a storage atmosphere containing oxygen in amount less than that found in normal air, whereby the atmosphere tends to become contaminated with the hydrocarbon gases; and removing the unsaturated hydrocarbon gases at such a rate as to limit the maximum unsaturated hydrocarbon gas in the storage atmosphere contacting the bananas to a safe level dependent upon the amount of oxygen in the atmosphere.  The storage atmosphere may contain 1-10% by volume of oxygen, 1-8% by volume of carbon dioxide and preferably has a high relative humidity of up to 95% and a temperature of 55-65 DEG F.  In a banana storage room, the unsaturated hydrocarbon content of the atmosphere therein is controlled by continuously displacing this atmosphere with oxygen reduced air, which air may also have an increased carbon dioxide content.  The catalytic burner apparatus described in Specification 1,067,017 is used to produce the oxygen reduced air.  The storage room also includes cooling means and means for adding water to raise the humidity of the atmosphere therein.
