Title: Improvements in or relating to centrifugal spiní¡í¡mes
IPC: D01H1/08
Filed: 1956-02-07
Abstract: 790,271. Centrifugal spinning. GARDELLA, A., and GARDELLA, C. Feb. 7, 1956 [Feb. 10, 1955], No. 3853/56. Class 120(2) [Also in Group XXXIV] A centrifugal spinning frame for long and hard vegetable fibres and in which the spinning cans are suspended and open at the bottom is provided with a support plate for each can to reduce vibration of the cans. Each support plate is rotatable and may be brought into and out of driving engagement with its associated can. Each can 2 suspended from a frame 1 has associated with it a support plate 16 provided with a rubber or leather ring 20 which makes a friction coupling with the edge of the can 2 when the plate 16 is raised into engagement. The support plates 16 for a set of cans are carried by a plate 9 which may be mounted for lateral movement, or supported on a lifting member 13 when the cans are to be engaged. When the cans 2 are to be doffed, yarn carriers are moved to positions in which, the yarn may collapse on to the carriers. The bottom edge 202 of each can may be serrated to sever the threads. A bevelled portion 402 of a can may engage a bevelled portion 216 of a support plate 16. In another embodiment, the inside edge of a can may engage a friction ring on the outer edge of the support plate which may be carried by a resilient bushing permitting it to adjust itself for misalignment with the spindle.

Title: Improvements in and relating to shaft or like couplings
IPC: F16D3/50
Filed: 1939-02-06
Abstract: 524,749. Universal joints and couplings. JULIEN, M. F. A. Feb. 6, 1939, No. 3866. Convention date, Feb. 5, 1938. [Class 80 (ii)] A shaft coupling comprising flanged members connected by rigid members extending axially between them and wherein resilient material is arranged between the rigid members and holes or sockets in the flanged members in which they are inserted has the resilient material adhesively connected to the sockets and rigid members by adhesive cement, bonding medium or by vulcanization or other known process. In the form shown in Fig. 3 the ends of the rigid pins 3 are completely enclosed in rubber which is bonded in sockets 5 inserted in holes in the plates 1, 2. The sockets 5 may be dispensed with and the rubber bonded in the holes. In a modification the ends of the pins are exposed and the holes extend right through the plates 1, 2. In the form shown in Fig. 8 the rigid members 18 are rectangular in cross-section and the separate masses of rubber are amalgamated into a single mass 16 extending between the plates 15, 15' bolted to the flanged members 1b, 2b. In the form shown in Fig. 10 a single mass of rubber is provided for each pin 8 which has a reinforcing flange 18. The metal sockets 9, 9' are provided with flanges 10, 10<1> which enclose an annular part of the rubber mass. The flange 18 may be dispensed with and the rubber and sockets may extend round the ends of the pins.

Title: Bottle inspection apparatus
IPC: G01N33/00
Filed: 1958-02-06
Abstract: 847,694. Bottle inspection apparatus. FENN, G. C., and TROPE, J. R. Feb. 6, 1958 [March 1, 1957], No. 3876/58. Class 40(3). In a transparent or translucent container inspection apparatus in which two photo-electric cells, positioned on one side of a belt conveying the containers to be inspected, receive visible and infra red light via the containers from two light sources positioned on the other side of the belt, a reject mechanism is operated when light from one source is intercepted by foreign matter in a container moving between the light sources and the cells. The arrangement is shown in plan in Fig. 2, the lamp 1 and lamp 2 below it (not shown) direct two beams of light across the belt B conveying the bottles A to the photoelectric cells 4, 5 (not shown). The cells are connected in opposition in the circuit shown in Fig. 1, 4<SP>1</SP> is a resistor common to both cell circuits and when the cells are equally illuminated no voltage appears across this resistor. When however cell 5 is obscured by foreign matter in the lower part of the bottle being inspected, the negative voltage developed across resistor 4<SP>1</SP> reduces the current flow through valve 13, the resulting positive voltage produced in the anode circuit of this valve fires the valve 19 which is normally held in a cut-off condition. Relay 34 is energized operating the heavy duty relays 35, 37 which energize the reject mechanism. This comprises solenoid 36 which is energized to advance the sensing wheel 45 mounted on the shaft 46 across the path of the bottles to prevent succeeding bottles being advanced until the soiled bottle is rejected, when the wheel is fully advanced switch 40 is operated energizing solenoid 41 which lowers the fence 56 to enable the bottle to be ejected into the circular magazine 57 provided to receive soiled bottles. Simultaneously solenoid 44 advances the arm 73 across the conveyer belt to push the soiled bottle into the magazine, when the arm is fully extended co-operating cam 77 breaks the circuit of relay 37 thereby releasing solenoid 44. The momentum of the returning arm causes it to overtravel and open switch 39 which releases relay 35 returning the sensing wheel and fence to their normal positions.

Title: Improvements in or relating to arrangements for controlling air-blowing means and fuel pumps for steam boilers of the single water passage type
IPC: F01K13/00
Filed: 1960-02-04
Abstract: 879,561. Regulating fuel and air supply to furnaces. SOC. D'ETUDE DE VEHICULES. Feb. 4, 1960 [Feb. 4, 1959; Feb. 10, 1959; Feb. 13, 1959], No. 3995/60. Class 51 (1). The air blower 6 and fuel pump 7 of a flashtype steam generator 1 are driven by a turbine 5 connected between the boiler 1 and the point of use of the steam. Parallel valves 8, 8<SP>1</SP> enable more or less of the steam to by-pass the turbine 5, the first valve 8 closing on a given fall in the pressure pv downstream of the turbine 5, and the second valve 81 closing on a further fall in the pressure. The closing of the valves increases the power applied to the turbine 5 and hence the air and fuel supply and the steam pressure generated in the boiler. A three-way cock 19 to return fuel to the storage tank and linked dampers 13, 14 controlling the air supply and an air vent 17 are operated to shut off the boiler without allowing the turbine 5 to race in the event of a sudden increase in the pressure generated in the boiler or downstream of the turbine 5. A valve 21 in the steam line beyond the turbine 5 closes this line if the pressure in it drops so far that the pressure of fuel feed is sufficient to overcome a spring 25, as in the event of a fracture of the steam line.

Title: Logic circuit

Abstract: 1,029,482. Semi-conductor logic circuits. SPERRY RAND CORPORATION. Feb. 4, 1963 [Feb. 13, 1962], No. 4390/63. Heading H3T. A logic circuit comprises a semi-conductor bistable switching element which may be switched from one state to the other by the simultaneous application of an input and a pulse from a first pulse source, and reset to the initial condition by the application of a second pulse source, the two pulse sources being coupled to different electrodes of the switching element. As shown in Fig. 2, if a negative clock pulse is applied from source 208 while a high level signal is applied to the input diodes 200, these diodes conduct and the constant current source 206 draws current through the diodes without switching the state of tunnel diode 228. If on the other hand diodes 200 are cut off by a low level input signal, the source 206 can only draw current from source 234 via the tunnel diode 228 and backward diode 218 and its state is switched to its high voltage one. The tunnel diode is reset to its low voltage state either by a delayed output from source 208 via switch 214, or by a separate reset clock source 212. Sources 222, 232 and backward diodes 220, 230 provide clamping. In a modification, Fig. 4 (not shown), the set clock pulses are applied direct to the cathode of the tunnel diode instead of via the backward diode. A number of stages as described may be cascade, Fig. 5 (not shown), the clock pulses of each stage being out of phase.
