Filed: 1972-06-28
Abstract: 1362491 Safety caps REFLEX CORP OF CANADA Ltd 28 June 1972 [1 July 1971 5 May 1972] 30271/72 Heading B8T  A safety cap assembly 30, e.g. for an aerosol dispenser, has an adapter 32, secured to a rim 20 of the dispenser and formed with a resilient flange 64, and a cap with locking lugs 60 which engage notches 42 in locking elements 38 formed on the adapter, to provide a bayonet joint, the cap lugs being held in the notches by the spring action of the flange 64 on an inner skirt 62 of the cap. As the cap is applied the flange 64 is depressed, -Fig. 2 (not shown), but a stop 56 on the cap engages a rim 66 of the adapter so that the cap cannot actuate the aerosol dispenser valve 22. The cap is then twisted sideways, its lugs 60 camming up surfaces 46 of the locking elements 38 before the flange 64 springs the bayonet joint into its locked position. The resilient adapter flange (164) may extend radially outwards, Figs. 4-5 (not shown), the flange (264) may be discontinuous, Fig. 8 (not shown), and the locking elements (338) may be set in recesses (337) in a side wall (336) of the adapter, Fig. 11 (not shown). The inner skirt 62 may be resilient and the flange 64 rigid.
Patent GB-876563-A (GB)
Title: Phosphatic fertilizers
Inventor: DEE THOMAS PRIDE
IPC: C05B11/06
Filed: 1956-10-05
Abstract: A process for the production of phosphatic fertilizers of high phosphate water solubility comprises reacting phosphate rock with at least 4 makes of phosphoric acid per mole of P2O2 in the rock and at least 4 moles of nitric acid per mole of P2O5 in the rock and neutralising the product so obtained e.g. with ammonia under agitation.  The acids may be added to the rock together or sequentially and the reactive time is suitably at least 10 minutes. During neutralization the slurry obtained from the acid attack on the rock is preferably strongly agitated, in which case the mode of adding the neutralizer is arbitrary, but if the agitation is not vigorous the neutralizer should be added batchwise at a temperature less than 60 DEG C. Convenient acids to use in the process are the commercial concentrated grades i.e. 50-70% concentrated phosphoric acid and 40-60% concentrated nitric acid.  The nitric acid may be replaced wholly or in part by urea nitrate.  Other neutralizing agents than ammonia are potassium hydroxide or potassium carbonate, and other fertilizer components such as ammonium sulphate ammonium nitrate or potassium chloride may be added to the product, which may also be granulated.

Abstract: 1514717 Automatic speed control GECELLIOTT AUTOMATION Ltd 30 June 1975 [12 July 1974] 30980/74 Heading G3R A speed control system for an electric motor has a motor speed feedback loop including a lowpass filter whose characteristic is varied temporarily to increase the system response e.g. to a step load. In the embodiment, for use with a D.C. motor, the output at 6 from a motor driven D.C. tachometer is compared in amplifier 7 with a speed reference, on 9, to form a current reference for an inner motor current control loop. The negative feedback components of speed control amplifier 7 form a first path 14, 15 and a second path 11, 12, 13, 21, 22, the latter being provided with grounded diodes 16, 17. In response to a step change in load e.g. in a strip rolling mill, the current in resistance 13 increases until one of the diodes 16, 17 breaks down. The amplifier feedback is then determined only by the first path 14, 15 whose components are such as to give a temporarily higher amplifier gain and bandwith, lower error time integral and thus faster system response. Non-linear network 20 limits the rate output of amplifier 7 and affords motor protection. Diode bridge 21, whose forward biasing current determines the switch on time of the diodes, and resistance 22, which determines when the diodes cease to conduct, may be omitted.

Abstract: 1437205 Frequency multiplex converter COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 3 July 1973 [3 July 1972] 31753/73 Heading H4R In a frequency multiplex converter incoming channels 1 to n are sampled and converted to digital values, if not already in digital form, multiplied by quadrature values of a digitized first carrier signal F1, digitally filtered, and the channel signals multiplied by digital values of quadrature related samples of respective carrier signals, at 20, and the resulting signals combined to give a digitally coded frequency multiplex group which is converted back to analogue form, at 25, and analogue filtered at 26. As described the incoming 12 speech channels are sampled at 112 kHz, fed through a to d converter 10, and are then converted from parallel to serial form by switch circuit 11 so that one sample of each channel is presented at the output of switch 11  during each 8À9 Ás period. The signals are fed to a multiplier 12 where the samples are multiplied by digitized samples of a 1850 Hz carrier signal in two quadrature phases from switch 13. The resulting in phase and quadrature components have their least significant bits discarded, to bring them back to their original number of bits, and are combined and fed to a digital filter 17 of passband 300 to 3400 Hz. In phase and quadrature components are combined in OR circuit 20 and fed to multiplier 21 to be multiplied by quadrature related digitized carrier signals from 22. The samples from each of the input channels are multiplied by respective carrier signals to convert them to their appropriate positions in the band 60 to 108 kHz, then the in phase and quadrature components are added at 24, after appropriate delay of the in phase component in 23, the signals converted back to analogue form in d to a converter 25 and analogue filtered in a 60 to 108 kHz bandpass filter 26. In an arrangement for dealing with two time division multiplex digital pem signals each carrying 32 channels, an array of delay lines is used to provide repeated samples of the signals for application to the multipliers (Fig. 4, not shown) while for two unsynchronized multiplex pcm signals individual digital multiplier and filter systems are provided, the outputs being combined after conversion to analogue form and before filtering, Fig. 5 (not shown).
