Abstract: 1,133,172. Sorting frangible containers. INTERNATIONAL MACHINERY CORP., S.A. Feb.2, 1967 [March 18, 1966], No.5019/67. Heading G1S.  In apparatus for detecting and separating defective frangible containers from sound containers e.g. glass jars, the containers are subjected to heat treatment sufficient to break any defective container, the broken containers being discharged from the apparatus. As shown in Fig.2, the containers C are discharged from feed conveyer 30 into pockets P of rotor 30 of a pressure feed valve 34, and subsequently are transferred to pockets P 1  of rotor 36 of the defective container detector 40, the sound containers being transferred on to pusher bars 24 of reel 20, whilst the broken containers fall into an accumulator 42. At the defective container detector 40 the containers are subjected to heat treatment, e.g. in the form of heated or cooled gas, such that broken containers fall through opening 118 into the accumulator 42, the sound containers being carried against an arcuate rail 140 to the reel 20. In a modification, the arcuate rail is omitted and further support means are provided for retaining the sound containers in their pockets whilst moving past the defective container accumulator opening. In a further modification, the pockets P 1  are sealed to the cylindrical casing.

Title: Integrated brake booster and adaptive braking modulator
IPC: B60T13/14
Filed: 1973-02-01
Abstract: 1360774 Combined brake booster and modulator BENDIX CORP 1 Feb 1973 5160/73 Heading F2F An integrated brake booster and adaptive braking modulator comprises a piston sliding in a chamber 36 of a housing and defining compartments on either side thereof, an operatoroperated valve 116 controlling communication to one compartment to move the piston which actuates a device for generating brake line pressure, a control unit responsive to the deceleration of at least one braked wheel and an electrically operated valve for communicating pressure fluid to the other compartment to cause reverse piston movement and brake line pressure relief upon occurrence of a skidding condition of the wheel. The chamber 36 is divided into two, each with a piston 44, 46 actuating a further piston 64, 72 via a rod 62, 70 to generate hydraulic pressure in front and rear brake lines respectively, a reservoir being provided in known manner for each further piston. An input rod 140 actuates a seat 130 to first close communication between the right-hand end of the chamber 36 and a return port 15 via passages 136, 138, 142, 144, and then open communication to that chamber end from a pressure source, e.g. an accumulator fed through a charging valve from a steering pump, via a port 12 and passages 122, 138, 136, to move the pistons 44, 46. During normal braking, for each piston 44, 46, a first solenoid valve 108 allows fluid communication between the left-hand end of the chamber 36 and a reservoir via passages 96, 98 and a port 16, and a second solenoid valve 100 blocks communication between the two ends of the chamber 36. A control device upon receipt of a wheel skid signal actuates the solenoid valves 100, 108 to allow communication between the two chamber ends, and to block flow through the port 16, thus equalizing pressures on either side of the pistons 44, 46, causing retraction, and pressure decrease in the associated brake lines. Alternatively, the solenoid 100 controls communication between the left-hand chamber end and an external accumulator. Upon pressure failure, further movement of the rod 140 causes a pivoted castor 148 on a cartridge 118 to engage the pistons 44, 46 to provide mechanical force transmission. Where the booster is fed directly from a steering pump and must allow continued fluid flow to the steering gear, a spool valve is combined with the input rod. This valve allows communication between an input port from the pump and an outlet port to the steering gear when not actuated, and also allowing communication from the right hand chamber end to a return port to a reservoir. Upon actuation, this latter communication is blocked and flow is allowed from the inlet port to the chamber end, with continued flow to the steering gear.

Abstract: 233,088. Schenck Eisengiesserei & Maschinenfabrik Darmstadt Ges., C., and Ohly, K. March 3, 1924. Testing balance of rotary apparatus.- Comprises apparatus for recording deflections on the circumferential surface of a test body during balancing characterized in that the recording member is movable axially as well as radially relative to the test body. In one form, a thin plate spring c is supported on a shaft d adjustably mounted in the machine so that the spring is given initial deflection. The point c<1> either directly or through a marking device, scribes on the surface test body a graph the peak or which indicates the highest deflection of the shaft. In another form the member c may be yieldingly but inelastically supported. It may be carried by equal and parallel links from a shaft, one of the joints of a link and the shaft being fitted with a friction brake. In this form the device remains in the position reached in maximum deflection, and the scribing point leaves the surface of the body at this point. In another form the scriber is guided axially of the shaft and is moved in this direction by a screw driven from the shaft. In still another form, the scriber c is supported in guides which are movable axially, and an adjustable link rigid with the part c bears on a fixed roller and the scriber is given an axial movement which is derived from the radial movement.

Abstract: 991, 494. Record/playback systems; correcting for inherent distortions; electric analogue calculating. DECCA Ltd. Jan. 10, 1964 [Feb. 11, 1963], No. 5536/63. Headings G4G and G5R. To compensate for amplitude non-linear distortion in a magnetic tape record/playback system or in a complete magnetic record/reproduced gramophone disc/play-back disc system, a non- linear network 18 is added to the system, preferably ahead of the recording head 23, to provide a reciprocal amplitude non-linearity to that inherent in the record/playback system. The three pushpull diode stages in the network 18 come into operation at three preset amplitude levels to give a polygonal response curve approximating the record/playback curve. In Fig. 2, the network is driven in antiphase about a transformer centretap 36, while in Fig. 1, (not shown), the same network forms part of a negative feedback loop in a record head amplifier. For lateral-cut discs, the distortion is largely third-harmonic and the diode stages are symmetrical For vertical modulations on a disc, second-harmonic distortion may be compensated by unbalanced diode stages. Frequency correction may be applied to replacing the resistors of the network 18 by impedances with reactive components and the filter may also incorporate means (not detailed) to reduce the amplitude distortions due to the variable tracking radii of the record and playback styli.

Abstract: 780,697. Friction clutches. DAIMLERBENZ AKT.-GES. Feb. 23, 1956 [Feb. 23, 1955], No. 5653/56. Class 80 (2). The axially slidable member of a friction clutch has a toothed connection with a non- slidable support, the teeth are formed such that in the disengaged position of the clutch axis parallel surfaces of the teeth are opposed to one another, and in the engaged position axisinclined surfaces are opposed to increase the frictional engagement of the clutch. In a motor vehicle change-speed gear, a driving shaft 1 has rigid therewith gears 2, 3 in constant mesh with gears 4, 5 freely mounted on a driven shaft 6. An intermediate piece 8 is splined to the shaft 6 and carries lozenge-shaped teeth 9 which interengage with similar teeth 11 within a hub 10. A coiled band spring 14 is splined to the hub and secured from relative axial movement by a resilient ring 16, the periphery of the spring being secured to a shift-ring 17. The spring 14 has a conical shape in both axial directions internally and externally, the angle between the cones being slightly less than corresponding clutch surfaces in the gears 4, 5. When the shift-ring 17 is moved to the right the teeth 9, 11 move from the position where the axis-parallel surfaces are opposed and the right-hand end of the spring 14 contacts the interior core of the gear 5. The spring is wound into engagement with the outer cone of the gear 5, and the resistance causes the inclined surfaces of the teeth 9, 11 to be opposed to transmit the torque and to increase the axial force pressing the spring 14 into engagement with the gear 5 and to retain it in the engaged position. The surface of the spring may be broken by grooves to break down the oil film between the friction surfaces.
