IPC: H01J25/68
Filed: 1957-05-23
Abstract: 863,002. Pneumatic tyres. PIRELLI S.p.A. May 23, 1957 [May 29, 1956; Jan. 31, 1957; April 18, 1957], No. 16434/57. Class 144 (2). For use on icy or snow-covered roads, a pneumatic tyre 1 has a circumferential groove 4 formed centrally in, and of one-third to onesixth the axial width of, the tread 3, to receive a removable tread ring 4 which forms part of the tyre tread and is held without slip in the groove 4 by the inflation pressure of the tyre, the treadring being substantially inextensible circumferentially and comprising a tread pattern of transverse bars 10 separated by grooves 9, and the ring either carrying anti-skid studs 6 projecting from each bar 10, or serving to retain removably in the groove 4, U-shaped (Fig. 5) or L-shaped (Fig, 8) brackets which carry stud-like projections 16. For use on normal road conditions, the ring 5 may be replaced by a similar ring, Fig. 4, having a circumferential rib tread pattern. Fig. 3 shows the tread-ring 5 comprised of hard rubber with a base reinforcement of one or more plies of textile or metal substantially circumferential cords, and carrying rivet members 11 each with a head 12 from which project frusto-conical radially outwardly tapering, round-ended studs 6. The U-shaped bracket 19 shown in Fig. 5 has bosses 20, 21 on its side walls 17, 18 to support the studs 16, and in this case, the tread groove 4 is recessed at circumferential intervals to receive the brackets so that it lies with its inner surfaces flush with the groove faces. The L-shaped bracket 32 Fig. 8, is used with the same recessed tread groove and such brackets may, therefore, be disposed in staggered sequence around the groove, or in opposed pairs to simulate the brackets 19. Reference has been directed by the Comptroller to Specification 825,632.

Title: Improvements in or relating to steroids
IPC: C07J9/00
Filed: 1952-07-01
Abstract: The invention comprises steroid compounds of the general formula <FORM:0722362/IV (b)/1> wherein R represents a hydroxy, alkoxy or acyloxy radical, and a process for the preparation of a 7(8), 9(11) diene steroid by treating a 7(8) unsaturated steroid having an aliphatic oxygenated substituent at C1 7 with a halogen, e.g. bromine, or a mercuric salt.  The substituent at C17 may be of the formula CH3C=R, where R is <FORM:0722362/IV (b)/2> <FORM:0722362/IV (b)/3> The keto group in the C17 substituent may be in the form of a ketal.  The starting steroid for the process may contain a hydroxy, alkoxy or acyloxy group in the 3-position.  It is preferred to dissolve the steroid in a solvent for treatment with the halogen or mercuric salt, suitable solvents mentioned being chlorinated hydrocarbons such as chloroform, carbon tetrachloride or ethylene dichloride, or alcohols such as methyl or ethyl alcohol.  The mercuric salt used in the above process may be a mercuric salt of a lower aliphatic carboxylic acid such as mercuric acetate or propionate.  The process is accelerated by the addition of a small amount of an aliphatic carboxylic acid such as acetic acid.  In the examples the following compounds are prepared: 3-b -acetoxyallo - 7, 9(11) - pregnadiene - 20 - one, methyl - 3 - b  - acetoxybisnorallo - 7, 9(11)-choladienate, enol acetate of 3-b -acetoxybisnorallo - 7, 9(11) - chloadienealdehyde and 3 - b -acetoxybisnorallo - 7, 9(11) - choladienic acid.

Title: Control system for the load control of engines of vehicles for agricultural work with rotary working implements
IPC: E02F3/84
Filed: 1976-04-23
Abstract: 1534314 Tractor power lift mechanism KUBOTA TEKKO KK 23 April 1976 [25 April 1975] 16583/76 Heading A1P [Also in Division G3] A control system for the powered lift of an agricultural tractor monitors both engine speed and depth (or draft) of the implement and combines their deviations from preset values to adjust the depth of cultivation so that both speed and depth are maintained more constant. It also provides a forced raising provision if the engine speed falls below a lower limit. In the control arrangement shown in Figure 2 the implement is raised and lowered by operation of electromagnetic valves 38, 42 respectively and the mode of operation is controlled by the manually operated 4 position gauged switch 53-57. The desired speed is set at 21 and the desired depth at 26 and the actual conditions monitored by sensors for speed 18, depth 29 and draft load 31. Under manual conditions, switch position M, the implement is raised and lowered by the operation of switch 58 and at all other switch positions switch 34 provides the 'up' control. A 'soft' engagement is achieved by the provision of a ground reference signal 49 and the arangement of comparators 48, 51 and intermittent signal generator 50 to cause valve 42 to operate in pulse fashion and thus slowly lower the implement. With the switch in position P the implement is controlled to keep the depth constant by the output signal of comparator 32 and in position D, for ploughing and like operation, a comparison is made of desired depth with draft load to control the height of the implement. With the switch in the RD position shown the tractor employs a power take off drive to the implement and a control is obtained as shown in Figure 3. The actual and set speeds are compared in comparator 35 to provide a speed error signal whose magnitude is assisted in further comparators 43, 45. If the error signal is above a magnitude set by 44 a comparator 43 provides an inhibiting signal to the 'down' control amplifier, i.e. the engine speed is below level a on Figure 3. If the engine speed falls below level c then comparator 45 operates the intermittent emitter 46 to provide a lifting signal direct to the 'UP' control amplifier 37. Under normal conditions when the speed lies between levels a and b the speed error signal is added to the preset depth signal in comparator 32. If the output of comparator 32 exceeds a dead band α then depending on the sign of the signal the implement height is adjusted in a direction that tends to restore the speed of the engine to its set speed. When the engine speed exceeds b then the signal provided by the comparator 25 is negligible and the control operates to keep the depth of cultivation constant.

Apparatus for recording working cycles of machine tools or the numbers of workpieces produced thereby comprises a graduated disc 28 rotatable in dependence on time and a writing arm 13 controlled by an electromagnet 3 and pivotable about a pin 14 between abutments with provision for emphasising say every tenth working cycle or workpiece to be recorded comprising means stepped onwards at the rhythm of the pivoting movements of the writing arm to influence the position of one of the abutments for every tenth recording. Each time an event to be recorded causes the electromagnet 3 to be energized a bell-crank lever 7 rocks anticlockwise against the action of a spring secured to a pawl 9 pivoted thereto. A weaker spring 17 acting on another bellcrank lever secured to the writing arm 13 rocks until a lug 20 encounters the periphery of a disc 12 while the writing arm 13 moves outwards marking the disc 28. When the electromagnet releases the lever 7 the pawl 9 advances the disc 12 through rachet wheel 8 and abutment surface 19 of lever 7 re-engages a pin 18 on lever 15 moving the writing arm in again until a projection 15a hits a fixed abutment 27. The periphery of the disc 12 has regularly spaced indentations 23 so that every tenth outward movement of arm 13 causes a longer mark to be recorded. Every fifth or tenth indentation 23 may be deeper still, as shown at 24, to cause even longer marks, 26.

Filed: 1960-05-11
Abstract: 956,446. Running generators in parallel. BAILEY METER CO. May 11, 1960 [May 11, 1959], No. 16699/60. Heading H2H. [Also in Division G3] A system of automatic load control for a generating station which may be part of a system, for apportioning generation between a number of stations or units in a station for producing power at the least cost comprises establishing an error signal proportional to the difference between signals representative of desired and actual generation, which error signal adjusts the loading of the station or stations. A station may be sub-divided into a number of units where it is desired to apportion the load within the station. The error signal may be converted into a control signal which functions as an index of the incremental generating cost, several control signals being fed to an apparatus which adjusts the stations outputs of each so that the incremental costs of each station are equal. The control signals may be adjusted to allow for the cost of transmission losses. Under transient load conditions the action of the apparatus is delayed to allow the various stations to feed the load proportionately within their maximum outputs, which proportions are then gradually re-adjusted if necessary, if the system is not working at the optimum economy. An error signal representative of the difference between actual and desired output is fed into a master controller 1 which transmits through a proportioning device 4 a control signal to station controllers 2a. The control signal may be modified at 5 to allow for line losses. The station may be divided into a number of units and a participation adjuster 8 determines the proportion of station load to be generated by each unit. A differential control action unit permits through a servo amplifier 10 and a control motor the immediate adjustment of a turbo alternator set or sets 12, which adjustment is subsequently modified by a unit 15 which is responsive to an error signal produced by a unit 13 which compares the control signal with the revised incremental cost developed from a function representative of the machine output. Selector switches 6, 16 change the station and units respectively from incremental cost control to pre-set automatic control, and a switch 18 provides a fixed incremental cost signal.
