Title: Storage installation
IPC: E04H6/24
Filed: 1971-06-25
Abstract: 1353374 Storage systems CENTRE STEPHANOIS DE RECHERCHES MECANIQUES HYDROMECANIQUE & FROTTEMENT 25 June 1971 [25 June 1970 25 Nov 1970 1 March 1971 18 March 1971 24 June 1971] 29982/71 Heading B8E In a storage system for vehicles or articles, transfer to and from the storage compartments is automatically effected by a self-driven lifting platform 15, Fig. 1, provided with means 17 for moving the articles into and out of the storage positions. Fig. 6 shows an embodiment in which vehicles are parked by a platform 36 which moves up helical guides 34, 35 and carries a trolley 42 which is projected into a storage compartment by a pusher chain 46. The platform carries a pallet which is raised and lowered to deposit the vehicle plus the pallet in the storage position. Fig. 7 shows an arrangement in which a trolley 85 is pushed from a platform 15 by a chain 46 which engages a toothed wheel 87. The latter is held against rotation by clutches 91, 92 whilst the platform 85 is removed. When a platform such as A is to be moved laterally from trolley 85 it is driven by a chain 46a through bevel gears 89, 94 and the clutch 91. The clutch 92 is disengaged so that the wheel 87 may be rotated by the chain 46, thereby driving the chain 46a. Similar chain drives may be arranged to move platforms in sinuous courses, Fig. 11 (not shown). Fig. 13 shows an embodiment in which the main platform 15 carries two subsidiary platforms 15a, 15b. More than two may be provided. Figs. 19, 20 show a platform 17 which restrains a vehicle during packing. Vehicles may be restrained by a series of projectable pins 142b, Figs. 21, 23, which engage the wheels. Fig. 24 shows clamping jaws 166, 170 which are extended from a position beneath the vehicle to clamp the wheels. Vehicles are centred with respect to the longitudinal axis of the trolley by fixed guides and with respect to the transverse axis by support plates 220, Fig. 27, which are mounted on rollers and move the vehicle backwards from a stop 225 until its axis 226 coincides with the axis 227 of the trolley. In a further embodiment, Fig. 30, the vehicle is centred and raised by stops 263, 263A, and forks 258, 258A which are mounted on parallelogram linkages operated by screws 272, 272A, and nuts 274, 275, 274A, 275A.

Title: Printing colours of the indanthrone series
Filed: 1932-10-26
Abstract: Indanthrone derivatives.--A halogenated indanthrone is treated with a sulphonating agent in the presence of an added dehydrating agent such as acetic anhydride, phosphorus pentoxide or sulphuryl chloride.  The azine or dehydroazine may be so treated or the latter may be treated with a sulphonating agent in presence of nitric acid, in this case the addition of dehydrating agent being unnecessary.  The same or similar products are obtained by treating a halogenated indanthrone with chlorsulphonic acid, dissolving the product together with untreated halogenated indanthrone in a sulphuric acid medium, and precipitating out the final product on dilution.  The products contain both sulphur and halogen in stable combination, possibly possessing sulphone groups, and are of value for printing purposes; they yield pure blue prints on cotton which are fast to bleach.  In examples the foregoing processes are illustrated using as starting-materials a halogenated indanthrone prepared as in Examples 1--4 of Specification 357,536, 3 . 3<1> - dibromoindanthrone (Specification 18196/05, [Class 2]) and Anthrene Blue G.CD.  The prior art and Specifications 16246/07, [Class 2], 9269/14, and 251,491, [both in Class 2 (iii)], also are referred to.  The Specification as open to inspection under Sect. 91 comprises the treatment of a halogenated indanthrone or the corresponding azine with a sulphonating agent in presence of a dehydrating agent or an oxidizing agent and includes further examples wherein the above chlorinated indanthrone (Specification 357,536) and a trichloro derivative prepared by chlorination in nitrobenzene are treated with a mixture of chlorsulphonic acid and oleum or monohydrate.  This subject-matter does not appear in the Specification as accepted.

Abstract: 813,090. Windscreen wipers. ANDERSON CO. Sept. 26, 1957 [March 28, 1957], No. 30213/57. Class 138(1). A connector for a windscreen wiper blade comprises a housing for receiving an end of a wiper arm and resilient means carried by the housing also for receiving the end of the arm and having an abutment which interlocks with a projection on the arm.

Title: Frequency generating system
IPC: H03L7/18
Filed: 1962-08-07
Abstract: 972,463. Signal generators. BENDIX CORPORATION. Aug. 7, 1962 [Aug. 9, 1961], No. 30249/62. Heading H3A. A signal generator for producing an output signal which is stabilized in frequency over a wide frequency range comprises an oscillator which emits signals over the desired range, a crystal controlled standard oscillator, means for dividing the output of the oscillator by any of a number of desired integers, comparing means receiving as inputs the output of the dividing means and the output of the crystal oscillator and means for varying the oscillator frequency in response to the output of the comparing means. The arrangement shown in Fig. 1 supplies output frequencies in steps of 1 kc./s. over the range 1.0 mc./s. to 1.999 mc./s. and includes a crystal controlled oscillator 10 providing an output of 500 pulses/sec. The output from the variable oscillator 18 is supplied to a dividing chain 14 which may be set to divide the oscillator output by factors of from 2000 to 3998 in steps of two. A first division by two is afforded by unit 26 and successive divisions by units of from one to ten is provided by each of three decade counters 28, 30 and 32 which are set by switches 20, 22, 24. A second divide by two circuit 34 acts to force the decade counters through two cycles, the first of which counts the output pulses from divider 26 in accordance with the setting of switches 20, 22 and 24 and the second which always counts the 1000 counts of the decades. The output pulses from unit 34 are applied with the crystal controlled oscillator pulses to a comparator 12 which provides an output to control oscillator 18 via unit 16. The comparator, Fig. 2, comprises a first flip-flop 40 which is triggered on by the divided output of the variable oscillator and a second flip-flop 44 which is triggered on by the output of the standard oscillator 10. Assume a pulse from the output of the standard oscillator arrives first, this triggers flip-flop 44 and also triggers via OR circuit 42 a multivibrator 52 which supplies a positive pulse to gate 50 and a negative pulse to gate 48. Gate 50 is closed by the output of flip-flop 44, hence a negative pulse of constant amplitude is supplied via gate 48 to the oscillator frequency control circuit 16 until the arrival of a pulse from the dividing network triggers flip-flop 40 to provide an output which closes gate 48. If the pulse from the dividing network arrives first, gate 48 is closed and a positive pulse of constant amplitude is applied to unit 16 via gate 50 until this is closed by the arrival of a pulse from the standard oscillator. Figs. 3 and 4 (not shown) indicate how the basic arrangement described may be extended to provide output signals in the range 2.5 mc/s.-29.999 mc/s.
