Title: Remote-control key
Inventor: MARIE-JOSEPHE MARIN
IPC: G07C9/00
Filed: 1991-06-18
Abstract: The invention relates to an apparatus enabling the security locks of entry doors to be opened by remote control from outside the flats (apartments) by a coded emission of infrared radiation. The code is tapped in (composed) and programmed by the user who can change it in the event of loss or theft of the remote-control key. This key is made up of an infrared-emitter case to which there corresponds a lock having a keypad invisible from outside the door and whose opening mechanism is triggered by the action of the infrared radiation. Moreover, the case is equipped with an alarm which is triggered if the code entered is different from that which has been programmed, and with a warning light for checking the run-down of the supply batteries, whereas the corresponding lock is fitted with reserve batteries ensuring operational autonomy in the event of a cut in the electrical circuit. The remote-control key is more particularly intended to be employed by individuals, but may also be employed in places of communal use.

Title: Pre-cooking of bakery products at 100 per cent humidity - producing products with no crust which can be handled and frozen until final cooking
Inventor: GUY DE LA SERVE
IPC: A21D15/02
Filed: 1992-05-14
Abstract: Loaves of bread or biscuits are pre-cooked, before their final cooking, in an atmos. of 100% humidity around the loaves. The surface temperature of the loaves during the pre-cooking is 75-100 deg.C. Cooking time is within 20% of the time defined by the relation T = m/3.85, where T is cooking time in minutes, and m is the mass of each load in grams. USE/ADVANTAGE - Products pre-cooked by this method have no surface crust or skin, while their internal structure is almost definitive. The process can be used with loaves of bread of all sizes, shapes and weights and other bakers products risen with yeast, such as croissants, brioches etc. and products risen with baking powder, such as cakes, and other products such as turnovers with no raising agents. The pre-cooked products are soft and can be handled without damage. The surface is not likely to crack as in existing methods. Pre-cooked products can be frozen for several days or months without impairing the appearance, flavour or smell of the final product.
